THE JOURNAL OF PAIN 2024; 25:104447. [PMID: 38122876 DOI: 10.1016/j.jpain.2023.12.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 11/28/2023] [Accepted: 12/10/2023] [Indexed: 12/23/2023]
Abstract
Young adults report chronic pain at rates of around 12% but lack access to clinical services. There is interest in learning how this emerging adult population engages with and responds to treatment. Using data from young adults aged 18 to 30 years (Mage = 25.8, SD = 3.2), taken from 4 previous randomised controlled trials, the current study investigated the feasibility, acceptability, and efficacy of an internet-delivered psychological pain-management intervention for young adults with chronic pain. We compared young adults in a treatment group (n = 104) with 1) a young-adult wait-list control group (n = 48), and 2) a treatment group reflecting the average-aged participant from the previous trials (39-63 years, n = 561). Feasibility was determined through treatment engagement, adherence and completion, and acceptability through a treatment satisfaction measure. Clinical outcomes were disability, pain intensity, anxiety, and depression; assessed at pre-treatment, post-treatment, and 3-month follow-up. Generalised estimation equation analyses were undertaken, using multiple imputations to account for missing data. Young adults had high engagement and acceptability ratings, though 34% did not complete the intervention. The treatment group significant improved across all outcomes, compared with control, with improvements maintained at follow-up. Post-treatment improvements were equivalent for young-adult and average-aged adult treatment groups, with no significant differences in feasibility or acceptability outcomes. Findings indicate young adults can engage with and show improvements following a psychological pain-management intervention designed for all adults with chronic pain. Future research is encouraged to examine outcomes related to role functioning of young adults, and moderators of treatment acceptability and efficacy for this population. PERSPECTIVE: Secondary analysis of data from 4 RCTs found an Internet-delivered psychological pain-management intervention acceptable and clinically efficacious for improving disability, anxiety, depression and pain intensity in young adults (18-30) with chronic pain.

Abstract
PURPOSE OF REVIEW Chronic pain affects a significant portion of the population globally, making it a leading cause of disability. Understanding the multifaceted nature of chronic pain, its various types, and the intricate relationship it shares with risk factors, comorbidities, and mental health issues like depression and anxiety is critical for comprehensive patient care. Factors such as socioeconomic status (SES), age, gender, and obesity collectively add layers of complexity to chronic pain experiences and pose management challenges. RECENT FINDINGS Low SES presents barriers to effective pain care, while gender differences and the prevalence of chronic pain in aging adults emphasize the need for tailored approaches. The association between chronic pain and physical comorbidities like cardiovascular disease, chronic obstructive pulmonary disease (COPD), and diabetes mellitus reveals shared risk factors and further highlights the importance of integrated treatment strategies. Chronic pain and mental health are intricately linked through biochemical mechanisms, profoundly affecting overall quality of life. This review explores pharmacologic treatment for chronic pain, particularly opioid analgesia, with attention to the risk of substance misuse and the ongoing opioid epidemic. We discuss the potential role of medical cannabis as an alternative treatment with a nuanced perspective on its impact on opioid use. Addressing the totality and complexity of pain states is crucial to individualizing chronic pain management. With different types of pain having different underlying mechanisms, considerations should be made when approaching their treatment. Moreover, the synergistic relationship that pain states can have with other comorbidities further complicates chronic pain conditions.

Abstract
Introduction Movement-evoked pain (MEP) impacts a substantial proportion of US adults living with chronic pain. Evidence suggests that MEP is influenced by numerous biopsychosocial factors and mediated by mechanisms differing from those of spontaneous pain. However, both characteristic and mechanistic knowledge of MEP remain limited, hindering effective diagnosis and treatment. Objectives We asked (1) can chronic pain, functional, psychosocial, and behavioral measures be grouped into descriptive domains that characterize MEP? and (2) what relationships exist between biopsychosocial factors across multiple domains of MEP? Methods We formed 6 characteristic domains from 46 MEP-related variables in a secondary analysis of data from 178 individuals (aged 45-85 years) with knee pain. Ratings of pain during 3 functional activities (ie, Balance, Walking, Chair Stand) were used as primary MEP variables. Pearson correlations were calculated to show linear relationships between all individual domain variables. Relationships between variables were further investigated through weighted correlation network analysis. Results We observed a unique combination of pain characteristics associated with MEP apart from general pain. Notably, minutes doing physical activity were inversely associated with multiple variables within 4 of the 6 domains. Weighted correlation network analysis largely supported our classification of MEP domains. Additional interdomain relationships were observed, with the strongest existing between MEP, Mechanical Pain, and Multiple Pain Characteristics and Symptoms. Additional relationships were observed both within and between other domains of the network. Conclusion Our analyses bolster fundamental understanding of MEP by identifying relevant mechanistic domains and elucidating biopsychosocial and interdomain relationships.

Abstract
INTRODUCTION Ganglionic local opioid analgesia (GLOA) at the superior cervical ganglion (SCG) is performed for pain control and is known to be an effective procedure. In this study, we evaluated the spread of the injectate in the area of the SCG. Our expectation was that there would be a correlation between the area and volume of the injectate spread and post-procedural outcome measures. METHODS This was a retrospective blinded review of magnetic resonance imaging (MRI) scans. Assessors evaluated the anatomical area of fluid spread, the furthermost spread from midline, any hampered spread and contact of contrast fluid with other structures. The efficacy of GLOA and complications were estimated. RESULTS The main solution spread reached from the C1 to C3 vertebrae. The furthest spread in the lateral and sagittal planes was 21.2 and 15.2 mm, respectively. The furthest craniocaudal spread was 63.5 mm. In 53.3% and 33% of interventions, the solution was found in the parapharyngeal space and in its "medial compartment," respectively. A correlation was found between pain relief and both solution spread and volume of solution spread. No hampered spread was recorded. A negative correlation between pain reduction and number of GLOA was observed. Higher pre-procedural pain intensity was correlated with higher pain reduction. We estimated pain relief in 93% of procedures correctly. No correlation between post-procedural Numerical Rating Scale (NRS) scores and different needle approaches was found. CONCLUSION For the transoral blocking technique, a strict laterodorsal needle direction is recommended to prevent possible block failures. A total volume of 2 ml injected into the parapharyngeal space and its "medial compartment" is recommended. Higher volumes may lead to uncontrolled distribution patterns.

Abstract
PURPOSE OF REVIEW Chronic Postsurgical Pain (CPSP) and the risk for long-term opioid dependency are known complications following major surgery. The idea of Transitional Pain Service (TPS) has been introduced as an interdisciplinary setting to manage pain in the perioperative continuum. We expand on the basic framework and principles of TPS and summarize the current evidence of the TPS and possible interventions to adress postoperative pain. Areas of future work in TPS-related research are discussed. RECENT FINDINGS Several studies support the effectiveness of TPS in reducing opioid consumption in the perioperative period and following discharge. Some studies also show an improvement in functional outcome with TPS with patients reporting lower pain severity and pain interference. The TPS aims to halt the progress of acute postoperative pain to CPSP by providing longitudinal support with patient-centered care. While some studies suggest a positive impact of TPS implementation in terms of reduction in postoperative opioid consumption and improvement of some functional outcomes, direct evidence in terms of reduction in the incidence of CPSP is still missing. The cost-effectiveness of TPS and the expansion of TPS through e-health services and digital applications also need to be evaluated.

Abstract
OBJECTIVE A substantial body of research supports what many nurses know from experience: empathy is at the heart of providing quality care. The major objective of this study was to identify unique mechanisms through which higher empathy translates into greater intentions to treat patients in pain employing novel methodology. METHODS Using an ecologically-valid scenario methodology, student nurses (N = 156) reviewed the narrative of a patient in chronic pain. They completed standard, valid measures of empathy toward the patient, perception of the patient's pain, and intention to provide pain-relieving treatment. Nursing student's personality traits were assessed and perception of patients' age and sex were experimentally manipulated. RESULTS Empathy was associated with higher intention to treat the patient in chronic pain irrespective of patients' age or sex. A moderated-mediation analysis confirmed that nursing students with higher empathy perceived the patient in the scenario as being in greater pain. This was correspondingly associated with higher intention to provide treatment. Nursing students' trait Extraversion was a moderator. CONCLUSION Empathy not only improves rapport between patients and providers but is related to intentions to provide pain-relieving treatment. PRACTICE IMPLICATIONS The clinical and educational importance of empathy in patient-provider relationships are discussed.

Abstract
BACKGROUND The relationship between chronic pain and the occurrence of falls in healthy older adults has been clarified in previous studies, but its relationship in older adults with disabilities has not. OBJECTIVE This study aimed to determine whether chronic pain is related to the occurrence of falls in older adults with disabilities. METHODS The participants were 101 older adults above 65 years old who used long-term care insurance services in Japan. Of these, 30 were fallers and 71 were non-fallers. Chronic pain, defined as pain lasting more than three months, was assessed using questionnaires, and the falls' occurrence was followed up for six months using a fall calendar. Logistic regression analysis was used to analyze the data, with falls as the dependent variable, chronic pain as the independent variable, and age, sex, body mass index, number of drugs, sleep disorders, and depression as covariates. RESULTS After adjusting for covariates, chronic pain significantly influenced the occurrence of falls (odds ratio: 3.168, 95% confidence interval: 1.057-9.495, p = .04). CONCLUSION Chronic pain was related to the occurrence of falls in older adults with disabilities. There is a need to focus on chronic pain presence in falls' prevention among older adults with disabilities.

Abstract
INTRODUCTION Chronic pain (CP) and depression/anxiety often coexist, worsening each other's symptoms. Treating this comorbidity is challenging. Tricyclic antidepressants and serotonin noradrenaline reuptake inhibitors are the first-line treatment options for this comorbidity, although sometimes they are not effective and/or well tolerated by patients, and there is little clinical evidence that selective serotonin reuptake inhibitors are useful for controlling CP. The antidepressant vortioxetine, with a multimodal mechanism that may help reduce pain, has proven clinical efficacy in patients with major depressive disorder (MDD). This study investigated vortioxetine's effectiveness for MDD and CP in clinical practice. METHODS This was a 3-month, multicenter, prospective, open-label, non-interventional pharmacoepidemiologic study. Patients (n = 64) with MDD (9-item Patient Health Questionnaire [PHQ-9] score ≥ 15) and CP (visual analogue scale [VAS] score ≥ 4) were treated with vortioxetine for 3 months (initiated with 10 mg/day, with flexible dosing thereafter [5-20 mg/day]). VAS, Clinical Global Impression (CGI), and Patient Global Impression (PGI) scales were used at baseline and at 1 and 3 months. Brief Pain Inventory (BPI), PHQ-9 scale, and Satisfaction with Medicines Questionnaire (SATMED-Q) were used at baseline and at 3 months. Adverse Events (AEs) were recorded. Descriptive statistics, chi-square tests, and Student's t-tests were used for paired data. RESULTS MDD patients showed a statistically significant improvement in VAS from baseline (mean [standard deviation (SD)]: 7.42 [0.69]) to 1 month (mean [SD]: 6.1 [0.81], P < 0.001) and 3 months (mean [SD]: 5.09 [1.26], P < 0.0001). Similarly, BPI and PHQ-9 scores showed significant improvement from baseline (mean [SD]: 6.20 [0.80] and 16.63 [1.47], respectively) to 3 months (mean [SD]: 4.73 [0.98] and 7.30 [2.60], P < 0.0001, respectively). Patients showed clinical improvement with CGI and PGI scales and reported being satisfied with the treatment in the SATMED-Q. A few mild EAs were registered. CONCLUSION Vortioxetine can relieve depressive and pain symptoms, with a good safety profile, in patients with MDD and CP.

Abstract
Chronic pain, a complex and debilitating condition, involves intricate interactions between central and peripheral inflammatory processes. Cytokines, specifically tumor necrosis factor (TNF) and interleukins (IL), are key mediators in the initiation and maintenance of chronic pain states. Sensory neurons expressing receptors for cytokines like TNF, IL-1, and IL-6 are implicated in peripheral sensitization, contributing to increased signaling of painful sensations. The potential of targeting TNF and IL for therapeutic intervention in chronic pain states is the focus of this review, with preclinical and clinical evidence supporting the use of TNF and IL modulators for pain management. The physiological and pathological roles of TNF in neuropathic pain is complex. Experimental evidence highlights the effectiveness of TNF modulation in mitigating pain symptoms in animal models and displays promising outcomes of clinical trials with TNF inhibitors, such as infliximab and etanercept. ILs, a diverse group of cytokines, including IL-1, IL-6, and IL-17, are discussed for their contributions to chronic pain through inflammation and peripheral sensitization. Specific IL modulators, such as secukinumab and tocilizumab, have shown potential in managing chronic neuropathic pain, as demonstrated in various studies and clinical trials. The pharmacokinetics, safety profiles, and challenges associated with TNF and IL modulators highlight the need for cautious medication monitoring in clinical practice. Comparative evaluations have revealed distinct efficacy and safety profiles among different cytokine modulators, emphasizing the need for personalized approaches based on the specific underlying causes of pain. Further research is necessary to elucidate the intricate mechanisms by which cytokines contribute to chronic pain, as well as to understand why they may affect pain differently in various contexts. Additionally, long-term safety profiles of cytokine modulators require more thorough investigation. This continued exploration holds the promise of enhancing our comprehension of cytokine modulation in chronic pain and shaping more potent therapeutic strategies for the future.

Abstract
Current epidemiological data estimate that one in five people suffers from chronic pain with considerable impairment of health-related quality of life. The pharmacological treatment is based on first- and second-line analgesic drugs, including COX-2 selective and nonselective nonsteroidal anti-inflammatory drugs, paracetamol, antidepressants, anti-seizure drugs and opioids, that are characterized by important side effects. N-palmitoylethanolamine (PEA) is a body's own fatty-acid ethanolamide belonging to the family of autacoid local injury antagonist amides. The anti-inflammatory and pain-relieving properties of PEA have been recognized for decades and prompted to depict its role in the endogenous mechanisms of pain control. Together with its relative abundance in food sources, this opened the way to the use of PEA as a pain-relieving nutritional intervention. Naïve PEA is a large particle size lipid molecule with low solubility and bioavailability. Reducing particle size is a useful method to increase surface area, thereby improving dissolution rate and bioavailability accordingly. Micron-size formulations of PEA (e.g., ultramicronized and co-(ultra)micronized) have shown higher oral efficacy compared to naïve PEA. In particular, ultramicronized PEA has been shown to efficiently cross the intestinal wall and, more importantly, the blood-brain and blood-spinal cord barrier. Several preclinical and clinical studies have shown the efficacy, safety and tolerability of ultramicronized PEA. This narrative review summarizes the available pharmacokinetic/pharmacodynamic data on ultramicronized PEA and focuses to its contribution to pain control, in particular as 'add-on' nutritional intervention. Data showing the ability of ultramicronized PEA to limit opioid side effects, including the development of tolerance, have also been reviewed.

Abstract
Introduction Isolating the effect of an intervention from the natural course and fluctuations of a condition is a challenge in any clinical trial, particularly in the field of pain. Regression to the mean (RTM) may explain some of these observed fluctuations. Objectives In this paper, we describe and quantify the natural trajectory of questionnaire scores over time, based on initial scores. Methods Twenty-seven untreated chronic low back pain patients and 25 healthy controls took part in this observational study, wherein they were asked to complete an array of questionnaires commonly used in pain studies during each of 3 visits (V1, V2, V3) at the 2-month interval. Scores at V1 were classified into 3 subgroups (extremely high, normal, and extremely low), based on z-scores. The average delta (∆ = V2 - V1) was calculated for each subgroup, for each questionnaire, to describe the evolution of scores over time based on initial scores. This analysis was repeated with the data for V2 and V3. Results Our results show that high initial scores were widely followed by more average scores, while low initial scores tended to be followed by similar (low) scores. Conclusion These trajectories cannot be attributable to RTM alone because of their asymmetry, nor to the placebo effect as they occurred in the absence of any intervention. However, they could be the result of an Effect of Care, wherein participants had meaningful improvements simply from taking part in a study. The improvement observed in patients with high initial scores should be carefully taken into account when interpreting results from clinical trials.

Abstract
BACKGROUND Every second human will experience a phase of neck pain in their lifetime and a high rate of chronicity exists. Because of the complexity and multiple influencing factors, chronic pain conditions are associated with a long treatment and diagnostic process. This leads to a prolonged healing process and high costs. OBJECTIVE To evaluate the effect of myofascial release on the variables of pain and range of motion in patients with chronic neck pain. METHOD Selection criteria were set to create a search algorithm for a systematic search in the databases: PubMed, Google Scholar, EBM Reviews, Medline, CINAHL, PEDro, and Science Direct. The risk of bias and the methodological quality was analyzed with the PEDro scale. RESULT Ten randomized controlled trials, with 549 participants met the eligibility criteria. The methodological quality was ranked from good to excellent. The myofascial release showed a significant difference in pain (p = 0.03), rotation to the right (p = 0.05), and lateral flexion to the right (p = 0.04), compared to other treatment methods. No significant effect was found for improvements in pressure pain threshold. CONCLUSION Modest effects are observed in pain reduction, suggesting potential benefits of myofascial release in managing chronic neck pain. Further research with standardized protocols and direct comparisons to established therapies is crucial for a comprehensive understanding of myofascial release efficacy. CONTRIBUTION OF THE PAPER What does the meta-analysis add to the current literature.

Abstract
Neuropathic pain can be caused by multiple factors, and its prevalence can reach 10% of the global population. It is becoming increasingly evident that limited or short-lasting response to treatments for neuropathic pain is associated with psychological factors, which include psychiatric comorbidities known to affect quality of life. It is estimated that 60% of patients with neuropathic pain also experience depression, anxiety, and stress symptoms. Altered mood, including stress, can be a consequence of several painful conditions but can also favor pain chronicization when preexisting. Despite the apparent tight connection between clinical pain and mood/stress disorders, the exact physiological mechanisms remain unclear. This review aims to provide an overview of state-of-the-art research on the mechanisms of pain related to the pathophysiology of depression, anxiety, and stress disorders.

Abstract
Background and objective Chronic pain is associated with a poor health-related quality of life (HRQL). Whereas the prescription rate of opioids increased during the last decades, their use in chronic non-malignant pain remains unclear. However, there is currently no clinical consensus or evidence-based guidelines that consider the long-term effects of opioid therapy on HRQL in patients with chronic non-cancer pain. This systematic review aims to address the question of whether opioid therapy improves HRQL in patients with chronic non-malignant pain and provide some guidance to practitioners. Databases and data treatment PubMed, EMBASE and CENTRAL were searched in June 2020 for double-blind, randomized trials (RCTs), comparing opioid therapy to placebo and assessed a HRQL questionnaire. The review comprises a qualitative vote counting approach and a meta-analysis of the Short Form Health Survey (SF-36), EQ-5D questionnaire and the pain interference scale of the Brief pain inventory (BPI). Results 35 RCTs were included, of which the majority reported a positive effect of opioids for the EQ-5D, the BPI and the physical component score (PCS) of the SF-36 compared to placebo. The meta-analysis of the PCS showed a mean difference of 1.82 [confidence interval: 1.32, 2.32], the meta-analysis of the EQ-5D proved a significant advantage of 0.06 [0.00, 0.12]. In the qualitative analysis of the mental component score (MCS) of the SF-36, no positive or negative trend was seen. No significant differences were seen in the MCS (MD: 0.65 [-0.43, 1.73]). A slightly higher premature dropout rate was found in the opioid group (risk difference: 0.04 [0.00, 0.07], p = .07). The body of evidence is graded as low to medium. Conclusion Opioids have a statistically significant, but small and clinical not relevant effect on the physical dimensions of HRQL, whereas there is no effect on mental dimensions of HRQL in patients with chronic non-malignant pain during the initial months of treatment. In clinical practice, opioid prescriptions for chronic non-cancer pain should be individually assessed as their broad efficacy in improving quality of life is not confirmed. The duration of opioid treatment should be determined carefully, as this review primarily focuses on the initial months of therapy.

PATIENT EDUCATION AND COUNSELING 2024; 123:108179. [PMID: 38367303 DOI: 10.1016/j.pec.2024.108179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 12/12/2023] [Accepted: 01/26/2024] [Indexed: 02/19/2024]
Abstract
OBJECTIVE The development of health literacy is important in the management of chronic pain and virtual reality may be an effective medium for its development. This study aims to understand the usability and acceptability of a virtual reality-based pain education system for the facilitation of health literacy. METHODS Semi-structured interviews were conducted with health professionals who had used a VR-based pain education system within their clinical practice, to explore perceptions of feasibility. Data collection and analyses were informed by the Unified Theory of Acceptance and Use of Technology and the Integrated Model of Health Literacy. RESULTS From 10 participants, the VR-based system was considered feasible in providing immersive experiential learning which addressed patient understanding and health-related communication. CONCLUSION VR appears to be perceived as an acceptable and feasible technology to support the development of health literacy in people with chronic pain. Its largest perceived benefit was its capacity to provide an immersive and entertaining alternative to conventional methods of pain education. PRACTICE IMPLICATIONS Virtual reality is considered as a feasible method of facilitating patient understanding and health-related communication related to chronic pain. Feasibility of such a tool relies clinically on time available, social expectations of VR, and the role of immersive and experiential learning within the management of chronic pain.

Abstract
Introduction Regular review of patients prescribed opioids for persistent non-cancer pain (PCNP) is recommended but not routinely undertaken. The PROMPPT (Proactive clinical Review of patients taking Opioid Medicines long-term for persistent Pain led by clinical Pharmacists in primary care Teams) research programme aims to develop and test a pharmacist-led pain review (PROMPPT) to reduce inappropriate opioid use for persistent pain in primary care. This study explored the acceptability of the proposed PROMPPT review to inform early intervention development. Methods Interviews (n = 15) and an online discussion forum (n = 31) with patients prescribed opioids for PCNP and interviews with pharmacists (n = 13), explored acceptability of a proposed PROMPPT review. A prototype PROMPPT review was then tested and refined through 3 iterative cycles of in-practice testing (IPT) (n = 3 practices, n = 3 practice pharmacists, n = 13 patients). Drawing on the Theoretical Framework of Acceptability (TFA), a framework was generated (including a priori TFA constructs) allowing for deductive and inductive thematic analysis to identify aspects of prospective and experienced acceptability. Results Patients felt uncertain about practice pharmacists delivering the proposed PROMPPT review leading to development of content for the invitation letter for IPT (introducing the pharmacist and outlining the aim of the review). After IPT, patients felt that pharmacists were suited to the role as they were knowledgeable and qualified. Pharmacists felt that the proposed reviews would be challenging. Although challenges were experienced during delivery of PROMPPT reviews, pharmacists found that they became easier to deliver with time, practise and experience. Recommendations for optimisations after IPT included development of the training to include examples of challenging consultations. Conclusions Uptake of new healthcare interventions is influenced by perceptions of acceptability. Exploring prospective and experienced acceptability at multiple time points during early intervention development, led to mini-optimisations of the prototype PROMPPT review ahead of a non-randomised feasibility study.

Abstract
Chronic pain leads to tau accumulation and hippocampal atrophy in mice. In this study, we provide one of the first assessments in humans, examining the associations of probable chronic pain with hippocampal volume, integrity of the locus coeruleus (LC)-an upstream site of tau deposition-and Alzheimer's Disease-related plasma biomarkers. Participants were mostly cognitively unimpaired men. Probable chronic pain was defined as moderate-to-severe pain in 2+ study waves at average ages 56, 62, and 68. At age 68, 424 participants underwent structural magnestic resonance imaging (MRI) of hippocampal volume and LC-sensitive MRI providing an index of LC integrity (LC contrast-to-noise ratio). Analyses adjusted for confounders including major health conditions, depressive symptoms, and opioid use. Models showed that men with probable chronic pain had smaller hippocampal volume and lower rostral-middle-but not caudal-LC contrast-to-noise ratio compared to men without probable chronic pain. Men with probable chronic pain also had higher levels of plasma total tau, beta-amyloid-42, and beta-amyloid-40 compared to men without probable chronic pain. These findings suggest that probable chronic pain is associated with tau accumulation and reduced structural brain integrity in regions affected early in the development of Alzheimer's Disease. PERSPECTIVE: Probable chronic pain was associated with plasma biomarkers and brain regions that are affected early in Alzheimer's disease (AD). Reducing pain in midlife and elucidating biological mechanisms may help to reduce the risk of AD in older adults.

Abstract
Chronic pain and insomnia symptoms are highly comorbid; however, the psychological mechanisms driving this comorbidity are not well understood. The aim of the present study was to assess whether 2 cognitive biases that occur separately in chronic pain and insomnia, that is, interpretation bias and attentional bias, are heightened in people with comorbid chronic pain and elevated insomnia symptoms. A final sample of N = 109 people with chronic pain and N = 79 people without pain who varied in insomnia symptoms were recruited through Prolific Academic to complete this cross-sectional study. Participants completed measures of sleep and pain-related interpretation bias (ambiguous sentences task) and attentional bias (dot-probe task), as well as questionnaires assessing insomnia symptoms, pain symptoms, and general psychological symptoms. We found an interaction between pain status and insomnia symptoms for sleep-related interpretation bias. That is, people with chronic pain showed greater sleep-related interpretation bias than those without pain, but only when insomnia symptoms were also elevated. This interaction did not extend to pain interpretation bias or attentional bias, although we did find an elevated pain interpretation bias in people with chronic pain compared to pain-free individuals. We also found that both pain and sleep-related interpretation bias were associated with depression symptoms, suggesting that interpretation bias could potentially drive a trimorbidity of chronic pain, insomnia, and depression. Taken together, these findings suggest promise for the role of interpretation bias in the mutual maintenance of chronic pain and insomnia symptoms and the importance of also considering depression. PERSPECTIVE: This article presents data on the cognitive biases that are present in chronic pain, and that are associated with increased insomnia symptoms. Identifying such cognitive biases could help in explaining the high comorbidity between chronic pain and insomnia, leading to more effective and targeted treatments.

Patient Expectations and Therapeutic Alliance Affect Pain Reduction Following Lidocaine Infusion in an Interdisciplinary Chronic Pain Clinic. THE JOURNAL OF PAIN 2024; 25:104443.

Abstract
Pain experience is affected by both ascending nociceptive signals and descending modulation. Expectations can affect pain experience and augment treatment-induced analgesia through descending inhibitory modulation of pain. This open-label, prospective cohort study examined the association between participant expectation ratings and pain reduction in adult participants with chronic pain receiving an intravenous lidocaine infusion. We aimed to explore whether: 1) participants' expectations of treatment efficacy were associated with pain reduction over 8 weeks after infusion; and 2) participants' therapeutic alliance was associated with expectations and/or pain reduction. We recruited 70 participants with chronic pain scheduled for lidocaine infusion. Study measures included pain intensity (pre-treatment, post-treatment, and daily for 8 weeks), treatment expectations (EXPECT), and therapeutic alliance (Trust in Physician and Working Alliance Inventory-Short Revised). Baseline treatment expectations were significantly correlated with pain reduction (r = .42, P < .01). Therapeutic alliance was significantly correlated with expectations (r = .27, P < .05) and pain reduction (r = .38, P < .01). This study quantifies the contribution of: 1) treatment expectations; and 2) therapeutic alliance to the magnitude of lidocaine-induced pain reduction. Results generate the hypothesis that focused efforts to augment treatment expectations and therapeutic alliance could serve to improve pain treatment outcomes. PERSPECTIVE: This study evaluates the relationship between pain reduction and ratings of: 1) treatment expectations; and 2) therapeutic alliance following an intravenous lidocaine infusion. Results generate the hypothesis that focused efforts to augment treatment expectations and therapeutic alliance could serve to improve pain treatment outcomes.

Abstract
BACKGROUND Chronic pain is linked to cognitive impairment; however, the underlying mechanisms remain unclear. In the present study, we examined these mechanisms in a well-established mouse model of Alzheimer's disease (AD). METHODS Neuropathic pain was modeled in 5-month-old transgenic APPswe/PS1dE9 (APP/PS1) mice by partial ligation of the sciatic nerve on the left side, and chronic inflammatory pain was modeled in another group of APP/PS1 mice by injecting them with complete Freund's adjuvant on the plantar surface of the left hind paw. Six weeks after molding, the animals were tested to assess pain threshold (von Frey filament), learning, memory (novel object recognition, Morris water maze, Y-maze, and passive avoidance), and depression-like symptoms (sucrose preference, tail suspension, and forced swimming). After behavioral testing, mice were sacrificed and the levels of p65, amyloid-β (residues 1-42) and phospho-tau in the hippocampus and cerebral cortex were assayed using western blotting, while interleukin (IL)-1β levels were measured by enzyme-linked immunosorbent assay. RESULTS Animals subjected to either type of chronic pain showed lower pain thresholds, more severe deficits in learning and memory, and stronger depression-like symptoms than the corresponding control animals. Either type of chronic pain was associated with upregulation of p65, amyloid-β (1-42), and IL-1β in the hippocampus and cerebral cortex, as well as higher levels of phosphorylated tau. CONCLUSIONS Chronic pain may exacerbate cognitive deficits and depression-like symptoms in APP/PS1 mice by worsening pathology related to amyloid-β and tau and by upregulating signaling involving IL-1β and p65.

Examining Psychological Factors as Contributors to Pain, Disability, and Physical Function in Geriatric Chronic Low Back Pain: A Prospective Analysis of the Delaware Spine Studies Cohort. THE JOURNAL OF PAIN 2024; 25:104448.

Abstract
In younger populations, risk factors from psychologically-focused theoretical models have become accepted as primary drivers behind the persistence of low back pain (LBP), but these risk factors have not been thoroughly assessed in older adult populations (60-85 years). To address this knowledge gap, we sought to examine longitudinal associations between both general and pain-related psychological risk factors and future pain intensity, LBP-related disability, and physical function (gait speed) outcomes in older adults with chronic LBP (n = 250). Questionnaires for general (ie, depressive symptoms) and pain-related psychological risk factors (ie, fear-avoidance beliefs, pain catastrophizing, and kinesiophobia) were collected at baseline. Questionnaire values were entered into principal component analysis to yield a combined psychological component score. LBP intensity (pain thermometers), LBP-related disability (Quebec Back Pain Disability Scale), and gait speed were measured at baseline and 12-month follow-up. Multiple linear regression was used to examine adjusted associations between baseline psychological component scores and each prospective outcome. The baseline psychological component score failed to independently predict 12-month LBP-related disability and gait speed after adjustment for baseline outcomes. Though the psychological component score was associated with 12-month LBP intensity after adjusting for baseline LBP intensity, this association diminished with full adjustment for other baseline characteristics. Cumulatively, general and pain-related psychological risk factors did not independently predict longitudinal pain, disability, and physical function outcomes in this cohort. Compared to younger populations with this condition, general and pain-related psychological risk factors may have less influence on the maintenance of chronic LBP in older adults. PERSPECTIVE: This article failed to establish consistent independent relationships between psychological factors and worse longitudinal pain, disability, and physical function outcomes in older adults with chronic LBP. The findings highlight a need to determine other age-specific biopsychosocial risk factors that may impact the maintenance of chronic pain in this patient population.

Abstract
INTRODUCTION Individuals with chronic pain often receive prescription opioid medication, and they may use cannabis to treat pain as well, although the risks of cannabis-opioid co-use are significant. This study aimed to investigate whether two transdiagnostic factors, emotion regulation and distress tolerance, had significant indirect effects in the relationship between pain and cannabis use in adults with chronic pain and an opioid prescription. METHODS Participants (n = 450; mean age = 38.6 ± 11.09) were recruited using Qualtrics panel service and were 75 % female and 79 % White, non-Hispanic. Participants completed a 30-minute self-report survey capturing three-month cannabis use, the Difficulties in Emotional Regulation Scale (DERS), and the Distress Tolerance Scale (DTS). The Graded Pain Scale (GCPS) assessed pain severity/intensity and disability. Analyses used the SPSS PROCESS macro, with both single (i.e., one transdiagnostic factor) and parallel indirect effects (i.e., both the DERS and DTS) examined. RESULTS There were statistically significant indirect effects for both the DERS and DTS in the relationship between pain intensity or disability and three-month cannabis use in single factor models. In the parallel indirect effect model, only the DERS was statistically significant (intensity indirect effect coefficient = 0.0195 % confidence interval [95 %CI] = 0.0065, 0.390; disability indirect effect coefficient = 0.0147, 95 %CI = 0.0055, 0.0274). CONCLUSIONS When examining parallel indirect effects, only emotional regulation and not distress tolerance mediated the relationship between chronic pain and cannabis use among those with an opioid prescription. Clinically, interventions aimed at improving emotional regulation in individuals with chronic pain can help limit cannabis and opioid co-use.

Abstract
OBJECTIVE (1) To identify the characteristics of PNE programs in terms of teaching-learning strategies, session modality, content delivery format, number of sessions, total minutes and instructional support material used in patients with chronic musculoskeletal pain, (2) to describe PNE adaptations for patients with different educational levels or cultural backgrounds, and (3) to describe the influence of the patient's educational level or cultural background on the effects of PNE. METHODS The PRISMA guideline for scoping reviews was followed. Nine databases were systematically searched up to July 8, 2023. Articles that examined clinical or psychosocial variables in adults with chronic musculoskeletal pain who received PNE were included. RESULTS Seventy-one articles were included. Studies found benefits of PNE through passive/active teaching-learning strategies with group/individual sessions. However, PNE programs presented great heterogeneity and adaptations to PNE were poorly reported. Most studies did not consider educational level and culture in the effects of PNE. CONCLUSIONS Despite the large number of studies on PNE and increased interest in this intervention, the educational level and culture are poorly reported in the studies. PRACTICAL IMPLICATIONS It is recommended to use passive and/or active teaching-learning strategies provided in individual and/or group formats considering the patient's educational level and culture.

Abstract
Psychosocial interventions for people with chronic pain produce significant improvements in outcomes, but these effects on average are modest with much variability in the benefits conferred on individuals. To enhance the magnitude of treatment effects, characteristics of people that might predict the degree to which they respond more or less well could be identified. People with chronic low back pain (N = 521) participated in a randomized controlled trial which compared cognitive therapy, mindfulness-based stress reduction, behavior therapy and treatment as usual. Hypotheses regarding predictors and/or moderators were based on the Limit, Activate, and Enhance model; developed to predict and explain moderators/predictors of psychosocial pain treatments. Results were: 1) low levels of cognitive/behavioral function at pre-treatment predicted favorable pre- to post-treatment outcomes; 2) favorable expectations of benefit from treatment and sound working alliances predicted favorable pre- to post-treatment outcomes; 3) women benefited more than men. These effects emerged without regard to treatment condition. Of note, high levels of cognitive/behavioral function at pre-treatment predicted favorable outcomes only for people in the treatment as usual condition. Analyses identified a set of psychosocial variables that may act as treatment predictors across cognitive therapy, mindfulness-based stress reduction and behavior therapy, as hypothesized by the Limit, Activate, and Enhance model if these 3 treatments operate via similar mechanisms. Findings point toward people who may and who may not benefit fully from the 3 psychosocial treatments studied here, and so may guide future research on matching people to these kinds of psychosocial approaches or to other (eg, forced-based interventions) non-psychosocial approaches. TRIAL REGISTRATION: The ClinicalTrials.gov Identifier is NCT02133976. PERSPECTIVE: This article examines potential predictors/moderators of response to psychosocial treatments for chronic pain. Results could guide efforts to match people to the most effective treatment type or kind.

Abstract
OBJECTIVES Chronic Idiopathic urinary retention is poorly understood. One small study suggests higher than expected rates of functional neurological disorder and pain comorbidity which may have implications for understanding the disorder. We investigated the frequency of functional neurological disorder, chronic pain other medical and psychiatric comorbidity, triggers of urinary retention, results of urodynamic assessment, medication history, management, and outcome in patients with chronic idiopathic urinary retention. METHODS A consecutive retrospective electronic notes analysis was undertaken of patients with chronic idiopathic urinary retention presenting to a secondary care urology clinic between Jan 2018-Jan 2021, with follow-up to their most recent urological appointment. RESULTS 102 patients were identified (mean age of 41.9 years, 98% female). 25% had functional neurological disorder (n = 26), most commonly limb weakness (n = 19, 19%) and functional seizures (n = 16, 16%). Chronic pain (n = 58, 57%) was a common comorbidity. Surgical and medical riggers to urinary retention were found in almost half of patients (n = 49, 48%). 81% of patients underwent urodynamic assessment (n = 83). Most frequently no specific abnormality was reported (n = 30, 29%). Hypertonic urethral sphincter was the most identified urodynamic abnormality (n = 17, 17%). We noted high levels of opioid (n = 50, 49%) and benzodiazepine (n = 27, 26%) use. Urinary retention resolved in only a small number of patients (n = 6, 6%, median follow up 54 months), in three cases spontaneously. CONCLUSION This preliminary data suggests idiopathic urinary retention is commonly comorbid with functional neurological disorder, and chronic pain, suggesting shared mechanisms.
