Abstract
Numerous studies have revealed that the ATP-gated ion channel purinergic 2X7 receptor (P2X7R) plays an important role in tumor progression and the pathogenesis of cancer pain. P2X7R requires activation by extracellular ATP to perform its regulatory role functions. During tumor development or cancer-induced pain, ATP is released from tumor cells or other cells in the tumor microenvironment (such as tumor-associated immune cells), which activates P2X7R, opens ion channels on the cell membrane, affects intracellular molecular metabolism, and regulates the activity of tumor cells. Furthermore, peripheral organs and receptors can be damaged during tumor progression, and P2X7R expression in nerve cells (such as microglia) is significantly upregulated, enhancing sensory afferent information, sensitizing the central nervous system, and inducing or exacerbating pain. These findings reveal that the ATP-P2X7R signaling axis plays a key regulatory role in the pathogenesis of tumors and cancer pain and also has a therapeutic role. Accordingly, in this study, we explored the role of P2X7R in tumors and cancer pain, discussed the pharmacological properties of inhibiting P2X7R activity (such as the use of antagonists) or blocking its expression in the treatment of tumor and cancer pain, and provided an important evidence for the treatment of both in the future.

Abstract
The synthesis and pharmacological activity of a new series of dual ligands combining activities towards the α2δ-1 subunit of voltage-gated calcium channels (Cavα2δ-1) and the μ-opioid receptor (MOR) as novel pain therapeutics are reported. A careful exploration of the pharmacophores related to both targets, which in principle had few common characteristics, led to the design of novel compounds exhibiting both activities. The construction of the dual ligands started from published Cavα2δ-1 ligands, onto which MOR ligand pharmacophoric elements were added. This exercise led to new amino-acidic substances with good affinities on both targets as well as good metabolic and physicochemical profiles and low potential for drug-drug interactions. A representative compound, (2S,4S)-4-(4-chloro-3-(((cis)-4-(dimethylamino)-4-phenylcyclohexyl)methyl)-5-fluorophenoxy)pyrrolidine-2-carboxylic acid, displayed promising analgesic activities in several in vivo pain models as well as a reduced side-effect profile in relation to morphine.

Bäckryd E. Should cancer pain still be considered a separate category alongside acute pain and chronic non-cancer pain? Reflections on ICD-11. FRONTIERS IN PAIN RESEARCH 2024; 5:1397413. [PMID: 38756912 PMCID: PMC11096455 DOI: 10.3389/fpain.2024.1397413] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Accepted: 04/24/2024] [Indexed: 05/18/2024] Open
Abstract
Introduction Traditionally, cancer pain has often been viewed as an independent third major category in pain medicine alongside acute pain and chronic non-cancer pain. However, the new chronic pain category MG30 in the eleventh version of International Classification of Diseases (ICD-11) includes cancer-related pain as one of its seven subgroups. In light of this, the aim of the paper is to investigate whether the traditional trichotomy should be replaced by a dichotomy between acute pain and chronic pain, cancer-related pain being part of both groups depending on the duration of pain. Methods The rationale for viewing cancer pain as a separate category is reviewed. Results Cancer being a deadly disease, cancer pain has a life-and-death and existential dimension that is different from non-cancer pain. It seems sensible to believe that this is an additional dimension to the suffering caused by cancer pain, and that clinicians should therefore take this existential dimension into consideration when assessing pain. Conclusion Without challenging the place of chronic cancer-related pain under the MG30 heading, it is concluded that while using ICD-11 in the future, pain clinicians should continue being mindful of the fact that the reality of death shapes the experience of cancer pain. The traditional trichotomy is therefore still valid and mirrors the fact that human beings are vulnerable (acute pain), temporal (chronic pain) and mortal (cancer pain).

Abstract
INTRODUCTION Foreign workers comprise a significant portion of Singapore's workforce. They face multiple challenges when working there. A hand injury may add to these stressors, causing profound psychological and social impact. There are few studies in the literature that have analyzed this effect. The primary objective of this study, the first of its kind in Singapore, is to investigate the psychological impact and functional outcomes of hand injuries among foreign workers. By assessing the prevalence of psychological conditions such as stress, anxiety, and depression, along with measuring functional impairment using validated tools, this study aims to provide insights into the psycho-social challenges faced by this vulnerable population. METHODS A single-encounter interview was conducted for eligible patients. Psychological impact was measured using the DASS-21, symptom severity and function with the QuickDASH, and pain with the VAS. Injury-specific and demographic data were also collected. The Mann-Whitney U test and the Chi-Squared test were applied for non-parametric variables and categorical data, respectively. The adjusted p-value was <0.05. RESULTS Eighty foreign workers were recruited. The mean age was 33 years, and the median age was 31.5 years (28.2 to 37.0). The majority were male (97.5%), married (60%), and had a salary of less than SGD1500 (USD1077) per month (81.3%). The most common mechanism of injury was penetrating (60%, n=48). Stress, anxiety, and depression were positively associated with limitations in daily function. Multivariate analysis found that limitations in daily function were independently associated with stress, anxiety, and depression, regardless of hand dominance. Conclusion: This study has shown a significant psychological and social impact of hand injuries among foreign workers in Singapore. There is potential for the development of screening and support programs for at-risk workers to cater to their mental well-being. We recommend that the psychological impact of hand injuries be factored into holistic management and rehabilitation with adequate time and resource allocation. An ancillary benefit is the improvement of productivity and overall contribution to Singapore's economy.

Exploring downstream effects of gender roles in healthcare decision-making and relationships within systems: A cross-sectional analysis of openness to treatment in pediatric headache. J Psychosom Res 2024; 179:111611.

Abstract
OBJECTIVE Socio-culturally defined identity factors present significant and often understudied influences on the experience, management, and treatment of chronic pain. For instance, there exist societal narratives about how males and females are expected to experience and express pain. Such gender roles may impact youth and caregiver openness to individual multidisciplinary treatments for pediatric headache. METHODS In this cross-sectional study, participants (N = 1087 youth/caregiver dyads, Mage = 14.5 years, 71% female, 97% cisgender, 77% White) completed a series of questionnaires, including Openness to Headache Treatment (OHT), upon presenting for initial multidisciplinary evaluation of chronic headache. Pearson correlations, independent samples t-tests and hierarchical regressions were used to analyze potential gender differences in youth and caregiver openness, as well as its relationships with pain-related and psychological factors. RESULTS Overall, female youth and their caregivers were more open to headache treatment, broadly and for individual interventions, when compared to male counterparts. Caregiver distress related to their child's headaches (i.e., fear and avoidance) was significantly correlated with openness in female youth and their caregivers, but not males. CONCLUSION Gendered patterns in healthcare decision-making in youth and caregivers provide insight on individual, societal, and systemic gender bias.

Abstract
This critical review highlights the advances in developing new molecules for treating pain syndrome, an important issue for human health. Acetaminophen (APAP, known as paracetamol) and nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used in clinical practice despite their adverse effects. Research is being conducted to develop innovative drugs with improved pharmaceutical properties to mitigate these effects. A more practical way to achieve that is to study well-known and time-tested drugs in their molecular combinations. Accordingly, the present work explores APAP and their combined chemical entities, i.e., prodrugs (soft drugs), codrugs (mutual prodrugs), and hybrids. Due to their molecular structure, APAP prodrugs or codrugs could be considered merged or conjugated hybrids; all these names are very fluid terms. This article proposed a structural classification of these entities to better analyze their advances. So, the following: carrier-linked O-modified APAP, -linked N-modified APAP derivatives (prodrugs), and direct- and spacer-N,O-linked APAP hybrids (codrugs) are the central parts of this review and are examined, especially ester and amide NSAID-APAP molecules. The C-linked APAP and nitric oxide (NO)-releasing APAP hybrids were also briefly discussed. Prime examples of APAP-based drugs such as propacetamol, benorylate, acetaminosalol, nitroparacetamol, and agent JNJ-10450232 weave well into this classification. The proposed classification is the first and original, giving a better understanding of the SAR studies for new pain relievers research and the design development for the analgesic APAP-(or NSAID)-based compounds.

Abstract
BACKGROUND Tramadol (TRM) and celecoxib (CLX) form a novel mixture that helps relieve acute pain when other painkillers have no action. It is also reported that these drugs, TRM and CLX, are used to control COVID-19 symptoms. OBJECTIVE The current work highlights three important pillars of modern pharmaceutical analysis, which are as follows; impurity profiling, greenness/whiteness studies and simplicity accompanied by sensitivity. Since 4-methyl acetophenone inhibits the human carbonyl reductase enzyme (type I) and since this compound may pose a health risk, it is crucial to regulate its concentration in all dosage forms of CLX. METHODS Two simple and green spectrophotometric methods were developed, namely third derivative (D3) and Fourier self- deconvulation (FSD), for resolving severely overlapped spectra of TRM and CLX in the presence of 4-methyl acetophenone (4-MAP) as a process-related impurity in their novel tablet combination. RESULTS The two approaches showed acceptable linearity with an excellent correlation coefficient. In both methods, TRM was measured when CLX and 4-methyl acetophenone were zero-crossing. The same procedure was applied for measuring CLX and its process-related impurity 4-MAP. CONCLUSION The methodologies developed were thoroughly validated in compliance with ICH (International Council on Harmonisation) guidelines. Student t- and F-tests revealed no statistically significant variation among the current methods and the reported method. HIGHLIGHTS No spectrophotometric methods have been published previously for the simultaneous analysis of TRM and CLX along with 4-MAP. As a result, the newly developed spectrophotometric approaches have great relevance and originality in the field of pharmaceutical analysis.

Abstract
OBJECTIVES The impact of benzodiazepine use on mortality in patients with chronic non-cancer pain (CNCP) has not been identified. We aimed to examine the factors associated with benzodiazepine use among patients with CNCP and examine whether long-term benzodiazepine usage is associated with mortality in patients with CNCP. METHODS This study was conducted using data from the National Health Insurance Service database of South Korea. We selected 2.5% of all adult patients diagnosed with musculoskeletal diseases (MSD) in South Korea from 2010 to 2019 using a stratified random sampling technique and included them in the analysis as patients with CNCP. The risk of 10-year all-cause mortality in patients with CNCP was investigated using the 2010 cohort of patients with CNCP. RESULTS The proportion of the study population that used benzodiazepine during the 10-year study period was 2.1% (390,683/18,770,234). Multivariable logistic regression showed that old age; increased Charlson comorbidity index (CCI); opioid, gabapentin or pregabalin, paracetamol, non-steroidal anti-inflammatory drugs, and Z-drugs usage; and underlying psychiatric comorbidities were associated with increased benzodiazepine use. In addition, benzodiazepine use was associated with increased 10-year all-cause mortality (adjusted hazard ratio: 1.03, 95% confidence interval: 1.01, 1.06; p < 0.001). CONCLUSIONS Benzodiazepine was prescribed to 2.1% of the patients with CNCP in South Korea from 2010 to 2019. Old age, increased CCI, underlying psychiatric comorbidities, and use of certain drugs are associated with increased use of benzodiazepines. In addition, benzodiazepine use is associated with 10-year all-cause mortality in patients with CNCP.

Abstract
RATIONALE Increasing evidence shows that imidazoline I2 receptor agonists enhance opioid-induced analgesia, suggesting that the combination of I2 receptor agonists with opioids could be a favorable strategy for pain control. However, the effect of I2 receptor agonists on the abuse liability of opioids is unknown. This study examined the impact of the I2 receptor agonist 2-BFI on some abuse-related behavioral effects of the opioid morphine in rats. OBJECTIVES The von Frey filament test was used to determine the antinociceptive effects of 2-BFI (intravenous, i.v.) in a rat model of complete Freund's adjuvant (CFA)-induced inflammatory pain. IV self-administration was used to assess the reinforcing effects of 2-BFI alone and to assess the effects of non-contingent injections of 2-BFI (i.p.) on morphine self-administration. A two-lever drug discrimination paradigm in which rats were trained to discriminate 3.2 mg/kg morphine (i.p.) from saline was used to examine whether 2-BFI or another I2 receptor agonist 2-(4,5-dihydroimidazol-2-yl)quinoline hydrochloride (BU224) affected the discriminative stimulus effects of morphine. RESULTS 2-BFI could not maintain reliable self-administration behavior in rats with no pain or CFA-treated inflammatory pain. However, pretreatment with 2-BFI (i.p.) produced dose-dependent decreases in the dose-effect curve of morphine self-administration. Both 2-BFI and BU224 did not substitute for morphine but significantly attenuated the discriminative stimulus effects of morphine. CONCLUSIONS These results suggest that I2 receptor agonists do not enhance, but in fact appear to decrease, the abuse liability of opioids, further supporting the potential utility of I2 receptor agonist-opioid combination therapy for pain control.

Abstract
Background The management of chronic pain may involve an array of tools, including radiofrequency thermocoagulation (Rf-Tc) of sensory nerve terminals. Like many other invasive procedures, Rf-Tc can generate anxiety in a lot of patients, either during the expectation of the procedure or in the course of it. Virtual reality hypnosis (VRH) is a promising tool for managing anxiety and pain in several situations, but its anxiolytic property has not been investigated in participants with chronic pain and going through a Rf-Tc procedure. Objectives The goal of this study was to evaluate the effectiveness of VRH for reducing self-assessed anxiety in participants with chronic pain, when received in preparation for Rf-Tc. Materials and methods This prospective, controlled trial was conducted in the Interdisciplinary Algology Centre of the University Hospital of Liège (Belgium). Participants were assigned to two groups: VRH or control (usual care). Assessment was carried-out at 4 time points: T0 (one week before Rf-Tc); T1 (pre-intervention, on the day of Rf-Tc); T2 (immediately after the VRH intervention outside of the Rf-Tc room); and T3 (right after Rf-Tc). Medical, sociodemographic data, anxiety trait and immersive tendencies were collected at T0. Anxiety state and pain intensity were assessed at each time points. Satisfaction was examined at T3. Results Forty-two participants were quasi-randomly assigned to the VRH or control group. No statistically significant interaction group by time was observed regarding all measured variables, including primary endpoint. However, a significant effect of time was found for anxiety and pain when considering both groups together, toward a progressive reduction. Conclusion In the context of our study, there appears to be no significant effect of VRH at reducing anxiety in participants with chronic pain undergoing Rf-Tc. Anxiety decreases along the procedure, while pain is attenuated by the local anesthetic infiltration of the Rf site. Our results suggest that the presence of a caregiver throughout the procedure might explain the progressive decrease in anxiety. Future randomized controlled trials are needed to precisely study the effectiveness of the VRH tool, and the possibility of using it as a complementary approach for anxiety during invasive procedures.

Abstract
Individuals suffering from chronic pain develop substance use disorders (SUDs) more often than others. Understanding the shared genetic influences underlying the comorbidity between chronic pain and SUDs will lead to a greater understanding of their biology. Genome-wide association statistics were obtained from the UK Biobank for multisite chronic pain (MCP, Neffective = 387,649) and from the Million Veteran Program and the Psychiatric Genomics Consortium meta-analyses for alcohol use disorder (AUD, Neffective = 296,974), cannabis use disorder (CanUD, Neffective = 161,053), opioid use disorder (OUD, Neffective = 57,120), and problematic tobacco use (PTU, Neffective = 270,120). SNP-based heritability was estimated for each of the traits and genetic correlation (rg) analyses were performed to assess MCP-SUD pleiotropy. Bidirectional Mendelian Randomization analyses evaluated possible causal relationships. Finally, to identify and characterize individual loci, we performed a genome-wide pleiotropy analysis and a brain-wide analysis using imaging phenotypes available from the UK Biobank. MCP was positively genetically correlated with AUD (rg = 0.26, p = 7.55 × 10-18), CanUD (rg = 0.37, p = 8.21 × 10-37), OUD (rg = 0.20, p = 1.50 × 10-3), and PTU (rg = 0.29, p = 8.53 × 10-12). Although the MR analyses supported bi-directional relationships, MCP had larger effects on AUD (pain-exposure: beta = 0.18, p = 8.21 × 10-4; pain-outcome: beta = 0.07, p = 0.018), CanUD (pain-exposure: beta = 0.58, p = 2.70 × 10-6; pain-outcome: beta = 0.05, p = 0.014) and PTU (pain-exposure: beta = 0.43, p = 4.16 × 10-8; pain-outcome: beta = 0.09, p = 3.05 × 10-6) than the reverse. The genome-wide analysis identified two SNPs pleiotropic between MCP and all SUD investigated: IHO1 rs7652746 (ppleiotropy = 2.69 × 10-8), and CADM2 rs1248857 (ppleiotropy = 1.98 × 10-5). In the brain-wide analysis, rs7652746 was associated with multiple cerebellum and amygdala imaging phenotypes. When analyzing MCP pleiotropy with each SUD separately, we found 25, 22, and 4 pleiotropic variants for AUD, CanUD, and OUD, respectively. To our knowledge, this is the first large-scale study to provide evidence of potential causal relationships and shared genetic mechanisms underlying MCP-SUD comorbidity.

PATIENT EDUCATION AND COUNSELING 2024; 119:108097. [PMID: 38065021 DOI: 10.1016/j.pec.2023.108097] [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: 09/25/2023] [Revised: 11/29/2023] [Accepted: 11/30/2023] [Indexed: 01/02/2024]
Abstract
BACKGROUND Interventions used in chronic pain management do not routinely use clinical hypnosis (CH), despite evidence to suggest its effectiveness in improving pain outcomes. This study aimed to explore the beliefs and attitudes of clinicians' towards the implementation of CH in chronic pain management. METHOD We conducted a cross-sectional qualitative analysis following online CH training. Clinicians working in three tertiary pain clinics, were recruited to participate in the online training program and invited to focus groups following completion of the training to explore beliefs and attitudes towards CH and the training program. RESULTS We identified three themes regarding barriers and two themes regarding facilitators to implementation of CH. Barriers: (i) misconceptions about CH, (ii) reduced confidence in implementing CH, and (iii) concerns about integrating CH with current treatment frameworks. Facilitators: (i) change in knowledge and attitude following training and (ii) an openness to exploring the technique and skills. The online training program was evaluated as positive with two themes: (i) training structure and (ii) training credibility. CONCLUSION Successful implementation of CH requires the development of training programs that address existing misconceptions of CH, allow for knowledge and skills acquisition, and adapt to the contextual setting within which the intervention is implemented. PRACTICAL IMPLICATIONS Training of clinicians in the process and skills required to deliver clinical hypnosis for chronic pain should be supported to facilitate its successful implementation into clinical settings.

Abstract
BACKGROUND Pain is highly burdensome, affecting over 30% of long-term care (LTC) residents. Pain significantly reduces residents' health-related quality of life (HRQoL), limits their ability to perform activities of daily living (ADLs), restricts their social activities, and can lead to hopelessness, depression, and unnecessary healthcare costs. Although pain can generally be prevented or treated, eliminating pain may not always be possible, especially when residents have multiple chronic conditions. Therefore, improving the HRQoL of LTC residents with pain is a priority goal. Understanding factors influencing HRQoL of LTC residents with pain is imperative to designing and evaluating targeted interventions that complement pain management to improve residents' HRQoL. However, these factors are poorly understood, and we lack syntheses of available research on this topic. This systematic review protocol outlines the methods to identify, synthesize, and evaluate the available evidence on these factors. METHODS This mixed methods review will follow the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. We will systematically search Medline, EMBASE, PsycINFO, CINAHL, Scopus, Cochrane Database of Systematic Reviews and ProQuest Dissertation and Thesis Global from database inception. We will include primary studies and systematically conducted reviews without restrictions to language, publication date, and study design. We will also include gray literature (dissertation and reports) and search relevant reviews and reference lists of all included studies. Two reviewers will independently screen articles, conduct quality appraisal, and extract data. We will synthesize results thematically and conduct meta-analyses if statistical pooling is possible. Residents and family/friend caregivers will assist with interpreting the findings. DISCUSSION This proposed systematic review will address an important knowledge gap related to the available evidence on factors influencing HRQoL of LTC residents with pain. Findings will be crucial for researchers, LTC administrators, and policy makers in uncovering research needs and in planning, developing, and evaluating strategies in addition to and complementary with pain management to help improve HRQoL among LTC residents with pain.

Abstract
Chronic pain complicates many diseases and is notoriously difficult to treat. In search of new therapeutic targets, pannexin-1 (Panx1) channels have sparked intense interest as a key mechanism involved in a variety of chronic pain conditions. Panx1 channels are transmembrane proteins that release ions and small molecules, such as adenosine triphosphate (ATP). They are expressed along important nodes of the pain pathway, modulating activity of diverse cell types implicated in the development and progression of chronic pain caused by injury or pathology. This review highlights advances that have unlocked the core structure and machinery controlling Panx1 function with a focus on understanding and treating chronic pain.

Abstract
OBJECTIVES The complexity of chronic pain requires interdisciplinary collaboration. Although this is recognisable in the framework for pain centres, few studies have investigated how interdisciplinary collaboration in pain centres is experienced by healthcare professionals, including the facilitators and barriers to interdisciplinary collaboration. The aim of the current study was therefore to investigate experiences of interdisciplinary collaboration in the treatment of patients with chronic pain among healthcare professionals in tertiary care pain centres. METHODS Eleven healthcare professionals, representing different healthcare disciplines from the four regional pain centres in Norway, participated in semi-structured individual interviews. The data were analysed thematically. RESULTS The results were categorised into three themes 'The best approach for chronic pain treatment', 'Collegial collaboration', and 'Challenges with interdisciplinary teamwork'. The informants valued the interdisciplinary work at the pain centre. They perceived it as the best approach for their patients and appreciated the support the collegial collaboration gave them as professionals. Although working together was rewarding and provided new insights, the informants also experienced the interdisciplinary teamwork as challenging, e.g., when the different professions disagreed on recommendations for further treatment or did not manage to work together as a team. CONCLUSION The informants found the interdisciplinary collaboration at the pain centre to provide the best treatment approach for their patients. It should be acknowledged that interdisciplinary teamwork can be challenging, and efforts should be put into establishing a good climate for collaboration and gaining knowledge about each profession's unique character and how they contribute to pain centre treatments.

Abstract
Introduction Chronic non-cancer pain (CNCP) is a lifelong condition with radical consequences, calling for management involving patients' families. Interventions based on the family systems nursing framework by Wright and Leahey have proved beneficial in other populations but require investigation in a CNCP population. This trial assumed that family nursing conversations (FNCs) based on the family systems nursing framework would increase patients' and family members' self-efficacy concerning CNCP management. Objective To investigate whether an intervention with FNCs as an add-on to the usual multidisciplinary treatment of CNCP would have an effect on patients' and family members' self-efficacy. Additionally, to investigate any impact on family function, health-related quality of life, anxiety, and depression. Methods The trial applied a prospective non-blinded quasi-experimental design with two comparable groups of patients and family members: a historical control group (HCG) and an intervention group (IG). The intervention was executed by nurses employed at a multidisciplinary pain center in the Capital Region of Denmark. HCG data were collected before the nurses' intervention training. The primary outcome was self-efficacy. Secondary outcomes were family function, health-related quality of life, anxiety, and depression. Results In total, 58 patients and 85 family members were included. The primary outcome, self-efficacy, detected no statistically significant between-group differences in mean change for patients, p = .990, or family members, p = .765. A statistically significant effect in favor of the IG was found in between-group differences in mean change in patients' behavioral family function, p = .034, and anxiety, p = .031. No statistically significant between-group differences were detected in family members' secondary outcomes. Conclusion The intervention had no effect on patients' or family members' self-efficacy but a positive effect on patients' behavioral family function and anxiety. The intervention was deeply affected by the COVID-19 pandemic. Hence, any results should be interpreted with caution.

Abstract
Background When theoretically discussing pain, the distinction between acute and chronic pain is not always taken into consideration. By contrast, informed by the pain medicine distinction between acute and chronic pain, the present theoretical paper analyses the phenomena of chronicity and chronification in the pain setting. Methods Philosopher Fredrik Svenaeus and his paper The phenomenology of chronic pain: embodiment and alienation (Continental Philosophy Review 2015;48:107-122) is used as a dialogue partner. Results Three aspects, relevant for clinicians, are discussed: (1) the distinction between emotion and mood, arguing that the process of chronification entails pain evolving from the former to the latter; (2) chronification as a process in which the pain patient becomes aware of his/her temporality, both the past and the future coming to the fore (as opposed to severe acute pain in which only the present counts, ie, getting rid of the pain now); (3) the acquisition of a pain-related narrative identity, interdisciplinary pain rehabilitation programs being described as helping patients regain a narrative identity that is not dominated by pain or by a fruitless chase after pain relief. Conclusion Chronic pain reminds us of our temporality and of the narrative character of our lives.

Abstract
The drive for a more person-centred approach in the broader field of clinical medicine is also gaining traction in chronic pain treatment. Despite current advances, a further departure from 'business as usual' is required to ensure that the care offered or received is not only effective but also considers personal values, goals, abilities, and day-to-day realities. Existing work typically focuses on explaining pain symptoms and the development of standardised interventions, at the risk of overlooking the broader consequences of pain in individuals' lives and individual differences in pain responses. This review underscores the importance of considering additional factors, such as the influence of chronic pain on an individual's sense of self. It explores innovative approaches to chronic pain management that have the potential to optimise effectiveness and offer person-centred care. Furthermore, it delves into research applying hybrid and individual formulations, along with self-monitoring technologies, to enhance pain assessment and the tailoring of management strategies. In conclusion, this review advocates for chronic pain management approaches that align with an individual's priorities and realities while fostering their active involvement in self-monitoring and self-management.

Abstract
Objectives. Adherence to treatment recommendations is critical for optimising quality of life for individuals with chronic pain, however adherence rates are low. This study explores the role that significant others are perceived to play in supporting or impeding treatment adherence, as well as examining patient views of the impact of their adherence regimes on their significant others.Design. 25 treatment seeking adults with chronic pain, who were currently living with a romantic partner or adult family member, took part in individual semi-structured interviews.Main outcome measures Interviews were transcribed verbatim and analysed using thematic analysis.Results. Three treatment adherence support themes emerged: social support (emotional, instrumental), positive social control, and supporting autonomy. Participants did not perceive significant others as having any negative influence on their adherence. By contrast, patients perceived that their adherence behaviors had both positive and negative effects on their significant others.Conclusions. These data present an encouraging perspective on the interpersonal context of coping with chronic pain. Significant others facilitated adherence in a range of ways. Future research identifying how best to integrate significant other support into patient self-management programs is needed, in order to lift the poor treatment adherence rates that are noted in the literature.

Abstract
ABSTRACT The decades since the inauguration of the International Association for the Study of Pain have witnessed major advances in scientific concepts (such as the biopsychosocial model and chronic primary pain as a disease in its own right) and in new technologies and approaches (from molecular biology to brain imaging) that have inspired innovations in pain research. These have guided progress in pain management and education about pain for healthcare professionals, the general public, and administrative agencies.

Objective Explore perceptions and preoccupations regarding use of medical cannabis against chronic musculoskeletal pain, among patients and physicians. Design Qualitative study using interviews with patients and physicians, based on the Theory of Planned Behavior (TPB). Setting The study was conducted in Quebec, Canada, in spring 2020. Subjects We included 27 adult patients and 11 physicians (GPs, anesthesiologists, psychiatrists, and a rheumatologist); the mean age of patients was 48.2 years; 59.3% of patients and 36.4% of physicians were women; 59.3% of patients used no medical cannabis at the time of study; 45.5% of physicians had never authorized it. Methods Semi-structured interviews were conducted, transcribed and for the qualitative analysis codes were developed in a hybrid, inductive and deductive approach. Guided by the TPB, facilitators and barriers, perceived benefits and harms, and perceived norms that may influence cannabis use or authorization were documented. Results Although medical cannabis is an interesting avenue for the relief of chronic musculoskeletal pain, doctors and patients agreed that it remained a last line option, due to the lack of scientific evidence regarding its safety and efficacy. The norms surrounding medical cannabis also play an important role in the social and professional acceptance of this therapeutic option. Conclusion Medical cannabis is seen as a last line option among interventions in the management of chronic pain, and attitudes and prior experiences play a role in the decision to use it. Study results may contribute to improved shared decision making between patients and physicians regarding this option.

Effect and safety of listening to music or audiobooks as a coadjuvant treatment for chronic pain patients under opioid treatment: a study protocol for an open-label, parallel-group, randomised, controlled, proof-of-concept clinical trial in a tertiary hospital in the Barcelona South Metropolitan area. BMJ Open 2023; 13:e074948. [PMID: 37696633 PMCID: PMC10496714 DOI: 10.1136/bmjopen-2023-074948] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Accepted: 08/21/2023] [Indexed: 09/13/2023] Open
Abstract
BACKGROUND Chronic non-cancer pain (CNCP) treatment's primary goal is to maintain physical and mental functioning while improving quality of life. Opioid use in CNCP patients has increased in recent years, and non-pharmacological interventions such as music listening have been proposed to counter it. Unlike other auditive stimuli, music can activate emotional-regulating and reward-regulating circuits, making it a potential tool to modulate attentional processes and regulate mood. This study's primary objective is to provide the first evidence on the distinct (separate) effects of music listening as a coadjuvant maintenance analgesic treatment in CNCP patients undergoing opioid analgesia. METHODS AND ANALYSIS This will be a single-centre, phase II, open-label, parallel-group, proof-of-concept randomised clinical trial with CNCP patients under a minimum 4-week regular opioid treatment. We plan to include 70 consecutive patients, which will be randomised (1:1) to either the experimental group (active music listening) or the control group (active audiobooks listening). During 28 days, both groups will listen daily (for at least 30 min and up to 1 hour) to preset playlists tailored to individual preferences.Pain intensity scores at each visit, the changes (differences) from baseline and the proportions of responders according to various definitions based on pain intensity differences will be described and compared between study arms. We will apply longitudinal data assessment methods (mixed generalised linear models) taking the patient as a cluster to assess and compare the endpoints' evolution. We will also use the mediation analysis framework to adjust for the effects of additional therapeutic measures and obtain estimates of effect with a causal interpretation. ETHICS AND DISSEMINATION The study protocol has been reviewed, and ethics approval has been obtained from the Bellvitge University Hospital Institutional Review Board, L'Hospitalet de Llobregat, Barcelona, Spain. The results from this study will be actively disseminated through manuscript publications and conference presentations. TRIAL REGISTRATION NUMBER NCT05726266.

Patients' and Family Members' Experiences of a Novel Nurse-Led Intervention Using Family Conversations Targeting Families Afflicted by Chronic Non-Cancer Pain. J Pain Res 2023; 16:3029-3043. [PMID: 37693340 PMCID: PMC10492541 DOI: 10.2147/jpr.s412721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 08/01/2023] [Indexed: 09/12/2023] Open
Abstract
Purpose To explore patients' and family members' experiences of participating in an intervention using nurse-led family nursing conversations (NLFCs) targeting families affected by chronic non-cancer pain (CNCP), including the perceived impact of the intervention on the individual and the family. CNCP substantially impacts patients and families. Due to a lack of simple treatment solutions, the condition needs to be managed rather than cured. Family involvement seems a promising tool, but research evaluating specific approaches is limited. Interventions based on the family systems nursing framework by Wright and Leahey have been helpful in other populations. Nonetheless, the approach warrants further investigation and evaluation in patients with CNCP. Patients and Methods A phenomenological hermeneutical design was applied, and individual interviews were conducted with ten patients and ten family members who received the intervention. The analysis was inspired by Ricoeur's philosophy of text interpretation. Findings Three themes emerged during the analysis. "Taking part in the intervention while being affected by previous experiences" showed that patients and family members were affected by different experiences and burdens and therefore entered the intervention with varied starting points. "Being empowered through validation and understanding" showed that participants mainly viewed the intervention as beneficial, increasing patients' and family members' mutual understanding and underpinning acceptance of the chronic pain condition. "Being receptive to the intervention - mechanisms contributing to achieving benefit" identified contributing mechanisms influencing patients' and family members' experiences of the intervention. These mechanisms included confidence in the nurses' facilitation of the intervention, the timing of the intervention, the participant's level of acceptance, and readiness to engage in the intervention. Conclusion and Relevance to Clinical Practice The intervention was mainly experienced as helpful. Thus, healthcare settings treating CNCP should consider implementing NLFC in clinical practice with adjustments to meet the vulnerability of the CNCP population.

Abstract
Background and purpose Given that chronic pain has become a major problem in recent years, affecting approximately 30% of the general population, this study used the Japanese version of the Short Form-8 (SF-8) to investigate (1) the quality of life (QOL) of patients with burning mouth syndrome (BMS) or persistent idiopathic facial pain (PIFP) (compared with a Japanese control group) and (2) whether therapeutic intervention improves the QOL and reduces pain (comparison between 0 and 12 weeks) of patients with BMS or PIFP. Materials and methods A total of 63 patients diagnosed with either BMS (n=45) or PIFP (n=18) were included in this study. The diagnostic criteria for BMS and PIFP were established based on the third edition of the International Classification of Headache Disorders. Results Our study results showed that while Physical Component Summary (PCS) in patients with BMS or PIFP improved with treatment, it did not improve to the national standard value (NSV) after 12 weeks of intervention. In contrast, the Mental Component Summary (MCS) improved to the same level as the NSV after 12 weeks of intervention. Conclusions We found that therapeutic intervention improves MCS and reduces pain; however, improving PCS requires time.

The effects of physical exercise on structural, functional, and biochemical brain characteristics in individuals with chronic whiplash-associated disorder: A pilot randomized clinical trial.

Abstract
BACKGROUND Exercise for people with whiplash associated disorder (WAD) induces hypoalgesic effects in some, but hyperalgesic effects in others. We investigated the exercise-induced neurobiological effects of aerobic and strengthening exercise in individuals with chronic WAD. METHODS Sixteen participants (8 WAD, 8 pain-free [CON]) were randomised to either aerobic or strengthening exercise. MRI for brain morphometry, functional MRI for brain connectivity, and magnetic resonance spectroscopy for brain biochemistry, were used at baseline and after the 8-week intervention. RESULTS There were no differences in brain changes between exercise groups in either the WAD or CON group, therefore aerobic and strengthening data were combined to optimise sample size. After the exercise intervention, the CON group demonstrated increased cortical thickness (left parahippocampus: mean difference = 0.04, 95% CI = 0.07-0.00, p = 0.032; and left lateral orbital frontal cortex: mean difference = 0.03, 95% CI = 0.00-0.06, p = 0.048). The WAD group demonstrated an increase in prefrontal cortex (right medial orbital frontal) volume (mean difference = 95.57, 95% CI = 2.30-192.84, p = 0.046). Functional changes from baseline to follow-up between the default mode network and the insula, cingulate cortex, temporal lobe, and somatosensory and motor cortices, were found in the CON group, but not in the WAD group. There were no changes post-exercise in brain biochemistry. CONCLUSION Aerobic and strengthening exercises did not exert differential effects on brain characteristics, however differences in structural and functional changes were found between WAD and CON groups. This suggests that an altered central pain modulatory response may be responsible for differential effects of exercise in individuals with chronic WAD.

THE INTERNATIONAL JOURNAL OF DRUG POLICY 2023; 119:104112.

Abstract
BACKGROUND Gabapentinoid medications are increasingly being used in chronic pain management, yet very little is known about the experiences of those using them. The aim of this study was to address this gap in the literature by qualitatively exploring the lived experiences of patients using gabapentinoids for chronic pain. METHODS Semi-structured interviews were conducted with 12 adults prescribed a gabapentinoid medication - either pregabalin or gabapentin - for chronic pain in Australia. Interviews were conducted in May 2022 via telephone or online video chat. Audio recordings of the interviews were transcribed verbatim, and data were analysed using reflexive thematic analysis. The Medication Adherence Model was used as a framework for synthesising the data and organising themes. RESULTS For participants in this study, the initial decision to use gabapentinoids for chronic pain was driven by a level of desperation for pain relief, a perceived lack of pain management alternatives, and a belief that the medication was safer and easier to access than opioids. However, once using gabapentinoids, experiences varied considerably with some viewing the medication as effective and safe, and others viewing it as useless or harmful. Some participants expressed concern that they were not adequately informed by their prescribers about the risks of gabapentinoid use. CONCLUSION These findings emphasise the importance of patient-provider communication and taking a patient-centred approach to gabapentinoid prescribing and de-prescribing. Future qualitative research in this area should involve primary care providers to gain a better understanding of factors driving increased gabapentinoid prescribing in chronic pain management as well as barriers to patient education.

Chronic thoracic pain after cardiac surgery: role of inflammation and biomechanical sternal stability. FRONTIERS IN PAIN RESEARCH 2023; 4:1180969. [PMID: 37637509 PMCID: PMC10450746 DOI: 10.3389/fpain.2023.1180969] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 07/28/2023] [Indexed: 08/29/2023] Open
Abstract
Introduction The pathogenesis of chronic chest pain after cardiac surgery has not been determinate. If left untreated, postoperative sternal pain reduces the quality of life and patient satisfaction with cardiac surgery. The purpose of the study was to examine the effect of chest inflammation on postoperative pain, risk factors for chronic pain after cardiac surgery and to explore how chest reconstruction was associated with the intensity of pain. Methods The authors performed a study of acute and chronic thoracic pain after cardiac surgery in patients with and without sternal infection and compared different techniques for chest reconstruction. 42 high-risk patients for the development of mediastinitis were included. Patients with mediastinitis received chest reconstruction (group 1). Their demographics and risk factors were matched with no-infection patients with chest reconstruction (group 2) and subjects who underwent conventional sternal closure (group 3). Chronic pain was assessed by the numeric rating scale after surgery. Results The assessment of the incidence and intensity of chest pain at 3 months post-surgery demonstrated that 14 out of 42 patients across all groups still experienced chronic pain. Specifically, in group 1 with sternal infection five patients had mild pain, while one patient experienced mild pain in group 2, and eight patients in group 3. Also, follow-up results indicated that the highest pain score was in group 3. While baseline levels of cytokines were increased among patients with sternal infection, at discharge only the level of interleukin 6 remained high compared to no infection groups. Compared to conventional closure, after chest reconstruction, we found better healing scores at 3-month follow-up and a higher percentage of patients with the complete sternal union. Conclusions Overall, 14 out of 42 patients have chronic pain after cardiac surgery. The intensity of the pain in mediastinitis patients significantly decreased at 3 months follow-up after chest reconstruction. Thus, post-surgery mediastinitis is not a determining factor for development the chronic chest pain. There is no correlation between cytokines levels and pain score except interleukin 6 which remains elevated for a long time after treatment. Correlation between sternal healing score and chronic chest pain was demonstrated.

In this study, we examined risk factors for depression in patients with pain conditions and associations between depression and long-term mortality in such patients. MATERIALS AND METHODS Data from the National Health Insurance Service database in South Korea were used in this cohort study. A total of 2.5% of adult patients diagnosed with pain conditions in 2010 were selected using a stratified random sampling technique and included for analysis. We performed multivariate logistic regression modelling to identify risk factors associated with depression and multivariate Cox regression modelling to determine whether depression is associated with 10-year survival outcomes in patients with pain conditions. RESULTS In total, data from 1808043 patients with pain conditions in 2010 were analyzed. Among them, 70148 (3.9%) patients had depression. Multivariate logistic regression modelling identified older age, comorbidities, analgesics, female sex, living in an urban area, and other underlying psychiatric morbidities as potential risk factors for depression in patients with pain conditions. Multivariate Cox regression revealed that 10-year all-cause mortality in patients with depression was 1.13-fold (hazard ratio, 1.13; 95% confidence interval, 1.11-1.16; p<0.001) higher than that in patients without depression and pain conditions. CONCLUSION We identified a few potential risk factors for depression among South Korean patients with pain conditions. Depression was associated with elevated 10-year all-cause mortality in patients with pain conditions.

Abstract
BACKGROUND In the future, extended reality technology will be widely used. People will be led to utilize virtual reality (VR) and augmented reality (AR) technologies in their daily lives, hobbies, numerous types of entertainment, and employment. Medical augmented reality has evolved with applications ranging from medical education to picture-guided surgery. Moreover, a bulk of research is focused on clinical applications, with the majority of research devoted to surgery or intervention, followed by rehabilitation and treatment applications. Numerous studies have also looked into the use of augmented reality in medical education and training. METHODS Using the databases Semantic Scholar, Web of Science, Scopus, IEEE Xplore, and ScienceDirect, a scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. To find other articles, a manual search was also carried out in Google Scholar. This study presents studies carried out over the previous 14 years (from 2009 to 2023) in detail. We classify this area of study into the following categories: (1) AR and VR in surgery, which is presented in the following subsections: subsection A: MR in neurosurgery; subsection B: spine surgery; subsection C: oral and maxillofacial surgery; and subsection D: AR-enhanced human-robot interaction; (2) AR and VR in medical education presented in the following subsections; subsection A: medical training; subsection B: schools and curriculum; subsection C: XR in Biomedicine; (3) AR and VR for rehabilitation presented in the following subsections; subsection A: stroke rehabilitation during COVID-19; subsection B: cancer and VR, and (4) Millimeter-wave and MIMO systems for AR and VR. RESULTS In total, 77 publications were selected based on the inclusion criteria. Four distinct AR and/or VR applications groups could be differentiated: AR and VR in surgery (N = 21), VR and AR in Medical Education (N = 30), AR and VR for Rehabilitation (N = 15), and Millimeter-Wave and MIMO Systems for AR and VR (N = 7), where N is number of cited studies. We found that the majority of research is devoted to medical training and education, with surgical or interventional applications coming in second. The research is mostly focused on rehabilitation, therapy, and clinical applications. Moreover, the application of XR in MIMO has been the subject of numerous research. CONCLUSION Examples of these diverse fields of applications are displayed in this review as follows: (1) augmented reality and virtual reality in surgery; (2) augmented reality and virtual reality in medical education; (3) augmented reality and virtual reality for rehabilitation; and (4) millimeter-wave and MIMO systems for augmented reality and virtual reality.

Abstract
This study aimed to examine the associated factors of oral glucocorticoid (GC) use in patients with chronic non-cancer pain (CNCP) associated with musculoskeletal diseases (MSDs) in South Korea. Moreover, we examined whether oral GC use was associated with long-term mortality in patients with CNCP. This population-based cohort study used data from the national registration database in South Korea. Using a stratified random sampling technique, we extracted the data from 2.5% of adult patients diagnosed with MSDs in 2010. Patients with CNCP-associated MSDs who were prescribed oral GC regularly for ≥30 days were defined as GC users, while the other patients were considered to be non-GC users. A total of 1,804,019 patients with CNCP were included in the final analysis, and 9038 (0.5%) patients were GC users, while 1,794,981 (95.5%) patients were non-GC users. Some factors (old age, comorbid status, pain medication use, and MSD) were associated with GC use among patients with CNCP. Moreover, in the multivariable time-dependent Cox regression model, GC users showed a 1.45-fold higher 10-year all-cause mortality (hazard ratio: 1.45, 95% confidence interval: 1.36-1.54; p < 0.001) than non-GC users. In South Korea, the 10-year all-cause mortality risk increased in the patients with CNCP using GC.

[PMID: 37263232 DOI: 10.1159/000530778] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Accepted: 04/14/2023] [Indexed: 06/03/2023]
Abstract
BACKGROUND Acupuncture has gained increasing international attention in recent decades. The act of incorporating acupuncture treatment into the routine treatment of COVID-19 in China drove us to review the 100 most influential articles of the last 20 years to learn about the current status and trends of acupuncture. METHOD Articles related to acupuncture from January 1, 2001, to July 4, 2022, were searched in the Clarivate Analytics Web of Science Core Collection database. The top 100 most cited publications were selected, and information was extracted. Software such as VOSviewer, GraphPad Prism, Scimago Graphica, and CiteSpace were used to visualize and analyze the extracted data. RESULT The 100 most cited articles were identified, with an average of 218 citations (range: 131-625). The majority of the top 100 articles were from the USA (n = 53). The institution that published the most highly cited papers was Harvard University (n = 16). The most influential team was Klaus Linde's group. Pain was the top-ranked journal in terms of the number of publications. The largest clusters for co-occurrence keyword analysis focused on acupuncture and electroacupuncture analgesia and brain imaging responses to acupuncture stimulation via functional MRI. The two highest strength burst keywords were "randomized controlled trials" and "osteoarthritis," with "randomized controlled trials" being a consistent burst keyword from 2011 to the present. CONCLUSION This study provides insight into articles of historical significance in the field of acupuncture through bibliometric analysis. These data should provide clinicians and researchers with insight into future directions related to acupuncture. Hintergrund Die Akupunktur hat in den vergangenen Jahrzehnten zunehmend die internationale Aufmerksamkeit auf sich gezogen. Die Einbeziehung der Akupunktur in die Routinebehandlung von COVID-19 in China hat uns dazu veranlasst, die 100 einflussreichsten Artikel der letzten 20 Jahre zu überprüfen, um etwas über den aktuellen Stand und die Trends in der Akupunktur zu erfahren. Methode Artikel mit Bezug zu Akupunktur vom 1. Januar 2001 bis 4. Juli 2022 wurden in der Clarivate Analytics Web of Science Core Collection Datenbank gesucht. Die 100 am häufigsten zitierten Veröffentlichungen wurden ausgewählt und die Informationen wurden extrahiert. Visualisierung und Analyse der extrahierten Daten erfolgten mithilfe der Software VOSviewer, GraphPad Prism, Scimago Graphica und CiteSpace. Ergebnis Es wurden die 100 am häufigsten zitierten Artikel ermittelt mit durchschnittlich 218 Zitierungen (Spanne: 131 bis 625). Der Großteil der 100 meistzitierten Artikel stammte aus den Vereinigten Staaten ( n = 53). Die Institution, die die meisten zitierten Artikel veröffentlichte, war die Harvard-Universität ( n = 16). Das einflussreichste Team war die Gruppe von Klaus Linde. Was die Zahl der Veröffentlichungen betrifft, war Pain die am häufigsten zitierte Zeitschrift. Bei der Analyse der Koinzidenz von Schlüsselwörtern lag der Fokus der größten Cluster auf Akupunktur-und Elektroakupunktur-Analgesie sowie auf den Reaktionen auf Akupunkturstimulation in den bildgebenden Untersuchungen des Gehirns mittels funktioneller MRT. Die beiden stärksten Burst-Schlüsselwörter waren “randomisierte kontrollierte Studien” und “Osteoarthritis,” wobei “randomisierte kontrollierte Studien” von 2011 bis heute durchgängig ein Burst-Schlüsselwort ist. Schlussfolgerung Diese Studie bietet einen Einblick in historisch bedeutsame Artikel auf dem Gebiet der Akupunktur mittels bibliometrischer analyse.

Abstract
Background There is a need for novel analgesics with favorable risk to benefit profiles. Oxytocin has recently gained attention for its potential analgesic properties. Aim The aim of this study was to perform an updated systematic review and meta-analysis evaluating the effect of oxytocin for pain management. Method Ovid MEDLINE, Embase, PsycINFO, CINAHL, and Clinicaltrials.gov were searched for articles reporting on associations between oxytocin and chronic pain management from January 2012 to February 2022. Studies published before 2012 that were identified in our previous systematic review were also eligible. Risk of bias of included studies was assessed. Synthesis of results was performed using meta-analysis and narrative synthesis. Results Searches returned 2087 unique citations. In total, 14 articles were included that reported on 1504 people living with pain. Results from meta-analysis and narrative review were mixed. Meta-analysis of three studies indicated that exogenous oxytocin administration did not result in a significant reduction in pain intensity relative to placebo (N = 3; n = 95; g = 0.31; 95% confidence interval [CI] -0.10, 0.73). Narrative review provided encouraging evidence that exogenous oxytocin administration reduced pain sensitivity among individuals with back pain, abdominal pain, and migraines. Results suggested that individual difference factors (e.g., sex and chronic pain condition) may influence oxytocin-induced nociception, but the heterogeneity and limited number of studies identified precluded further investigation. Discussion There is equipoise for the benefit of oxytocin for pain management. Future studies are imperative and should undertake more precise exploration of potential confounds and mechanisms of analgesic action to clarify inconsistency in the literature.

Abstract
PURPOSE This study aimed to investigate the association of modifiable lifestyle factors with long-term survival outcomes in patients with chronic non-cancer pain (CNCP) in South Korea. METHODS This population-based cohort study used data from the National Health Insurance Service database in South Korea. We considered three lifestyle factors from the standard health examination (smoking status, alcohol consumption, and physical activity). RESULTS A total of 1,298,314 patients with CNCP were analyzed; moreover, the 5-year all-cause mortality rate was 3.3% (42,875 patients). In the multivariable Cox regression model, in the previous-smoker and current-smoker groups, it was 5% (hazard ratio [HR]:1.05, 95% confidence interval [CI]:1.02-1.08; P = 0.003) and 65% (HR: 1.65, 95% CI: 1.60-1.69; P < 0.001) higher, respectively, than that in the never-smoker group. The 5-year all-cause mortality was 19% (HR: 1.19, 95% CI: 1.14-1.24; P < 0.001) higher in the heavy-alcohol-consumption group than in the non-alcohol-consumption group. Compared with those without mild physical activity, patients who engaged in mild physical activity for 1-3 (HR: 0.89, 95% CI: 0.87-0.92; P < 0.001), 4-5 (HR: 0.88, 95% CI: 0.86-0.91; P < 0.001), and 6-7 (HR: 0.90, 95% CI: 0.88-0.93; P < 0.001) days per week exhibited a significantly decreased 5-year all-cause mortality. The association between moderate/intensive physical activity and 5-year all-cause mortality yielded similar results. CONCLUSION Lifestyle factors, including previous/current smoking, heavy alcohol consumption, and physical activity, were associated with a higher 5-year all-cause mortality risk among patients with CNCP in South Korea.

COMMunity of Practice And Safety Support for Navigating Pain (COMPASS-NP): study protocol for a randomized controlled trial with home care workers. Trials 2023; 24:264. [PMID: 37038235 PMCID: PMC10088173 DOI: 10.1186/s13063-023-07149-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Accepted: 02/08/2023] [Indexed: 04/12/2023] Open
Abstract
BACKGROUND Chronic pain is a prevalent and costly problem that often has occupational origins. Home care workers (HCWs) are at high risk for work-related injuries, pain, and disability. Current treatments for chronic pain emphasize medications, which are an inadequate stand-alone treatment and can produce significant adverse effects. METHODS In this translational study, we will adapt an established work-based injury prevention and health promotion program (COMmunity of Practice And Safety Support: COMPASS) to address the needs of HCWs experiencing chronic pain. COMPASS employs peer-led, scripted group meetings that include educational content, activities, goal setting, and structured social support. The translated intervention, named COMPASS for Navigating Pain (COMPASS-NP), will be delivered in an online group format. Safety protections will be strengthened through an ergonomic self-assessment and vouchers for purchasing ergonomic tools. Educational content will integrate a self-management approach to chronic pain using proven cognitive-behavioral therapy (CBT) principles. We will use a mixed-methods hybrid type 2 evaluation approach to assess effectiveness and implementation. A cluster-randomized waitlist control design will involve 14 groups of 10 HCWs (n = 140) recruited from Washington, Oregon, and Idaho. Half of the groups will be randomly selected to complete the intervention during the first 10 weeks, while the waitlist groups serve as controls. During weeks 10-20, the waitlist groups will complete the intervention while the original intervention groups complete a follow-up period without further intervention. Our primary hypothesis is that COMPASS-NP will reduce pain interference with work and life. Secondary outcomes include injury and pain prevention behaviors, pain severity, changes in medication use, risk for opioid misuse, well-being, physical activity, and sleep. Qualitative data, including phone interviews with group facilitators and organizational partners, will evaluate the implementation and guide dissemination. DISCUSSION The results will advance the use and knowledge of secondary prevention interventions such as ergonomic tools and cognitive behavior therapy, to reduce injury, pain, and disability and to encourage appropriate uses of analgesic medications among HCWs.

Abstract
BACKGROUND Burning mouth syndrome (BMS) is characterised by persisting burning pain of the oral mucosa, and its etiopathogenesis remains poorly understood. OBJECTIVES Our study aimed to detect the expression of miRNA-206 in the blood and clarify the relationship among miRNA-206, pain, anxiety and depression of BMS patients. METHODS Thirty patients with BMS and 30 healthy individuals were enrolled in the experimental and control groups, respectively. Data on medical history and clinical oral examination for all participants were collected. Simultaneously, scores of Visual Analogous Scale (VAS), Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) were administered. The expression level of miRNA-206 in plasma were determined by RT-(q)PCR. Finally, the relationship of miRNA-206 expression with the VAS score, SAS score, and SDS score was analysed. Chi-square test and t-test were used for statistical analysis of the data, and p < .05 was considered statistically significant. RESULTS The majority of the patients with BMS identified the tongue as the main pain area, and showed dry mouth and poor sleep quality. The SAS and SDS scores of patients with BMS were higher than those of healthy controls (p < .05) and were positively correlated with VAS pain score. In addition, miRNA-206 expression was higher in patients with BMS than in healthy individuals (p < .05), and was positively correlated with the VAS and SDS scores (p < .05). CONCLUSIONS Patients with BMS suffer from pain and tend to be more anxious and depressed than healthy controls. miRNA-206 expression in the peripheral blood of patients with BMS is positively correlated with pain and depression, which may be involved in the pathogenesis of BMS.

Abstract
OBJECTIVES to estimate the burden of disease related to chronic pain in Ecuador. METHODS We used Global Burden of Disease (GBD) methods to estimated disability-adjusted life years (DALYs) related to chronic pain in Ecuador. We focused on chronic pain related to lumbar pain, osteoarthritis, post-herpetic neuralgia, diabetic neuropathy, cancer-related pain, and other musculoskeletal pain. We estimated the prevalent cases by sex and age group using literature data. We only estimated years lived with disability using disability weights obtained from the GBD, with the assumption that no premature death would be related to pain. We used a prevalence-based approach to estimate cases by sex and age group using literature, without discounting or age adjustment. We calculated total DALYs and DALYs/100,000 inhabitants. RESULTS Our estimated yielded a total of 3,644,108 patients with chronic pain. They would produce 256,090 DALYs or 1,483 DALYs/100,000 inhabitants attributable to chronic pain. Low back pain, osteoarthritis and cancer-related pain were the drivers of DALY production. CONCLUSIONS Chronic pain is an important source of burden of disease. It is comparable to other important causes such as headaches, stroke, diabetes and chronic obstructive pulmonary disease, among others. Low back pain, osteoarthritis and other musculoskeletal pain were the biggest contributors given their high prevalence.

Non-pharmacological and non-invasive interventions for chronic pain in people with chronic obstructive pulmonary disease: A systematic review without meta-analysis. Respir Med 2023; 211:107191. [PMID: 36889522 DOI: 10.1016/j.rmed.2023.107191] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Revised: 02/18/2023] [Accepted: 03/03/2023] [Indexed: 03/08/2023]
Abstract
OBJECTIVES Chronic Obstructive Pulmonary Disease (COPD) is complicated by chronic pain. People with COPD report higher pain prevalence than the general population. Despite this, chronic pain management is not reflected in current COPD clinical guidelines and pharmacological treatments are often ineffective. We conducted a systematic review that aimed to establish the efficacy of existing non-pharmacological and non-invasive interventions on pain and identify behaviour change techniques (BCTs) associated with effective pain management. METHODS A systematic review was conducted with reference to Preferred Reporting Items for Systematic Review (PRISMA) [1], Systematic review without Meta analysis (SWIM) standards [2] and Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidelines [3]. We searched 14 electronic databases for controlled trials of non-pharmacological and non-invasive interventions where the outcome measure assessed pain or contained a pain subscale. RESULTS Twenty-nine studies were identified involving 3,228 participants. Seven interventions reported a minimally important clinical difference in pain outcomes, although only two of these reached statistical significance (p < 0.05). A third study reported statistically significant outcomes, but this was not clinically significant (p = 0.0273). Issues with intervention reporting prevented identification of active intervention ingredients (i.e., BCTs). CONCLUSIONS Pain appears to be a meaningful issue for many individuals with COPD. However, intervention heterogeneity and issues with methodological quality limit certainty about the effectiveness of currently available non-pharmacological interventions. An improvement in reporting is required to enable identification of active intervention ingredients associated with effective pain management.

Abstract
OBJECTIVES To give an overview of central aspects of pain medicine-specific clinical reasoning when assessing a pain patient. Clinical reasoning is the thinking and decision-making processes associated with clinical practice. METHODS Three core pain assessment areas that are crucial for clinical reasoning in the field of pain medicine are discussed, each of them consisting of three points. RESULTS First, it is important to distinguish acute, chronic non-cancer, and cancer-related pain conditions. This classical and very simple trichotomy still has important implications treatment-wise, e.g., concerning the use of opioids. Second, the pain mechanism needs to be assessed. Is the pain nociceptive, neuropathic, or nociplastic? Simply put, nociceptive pain has to do with injury of non-neural tissue, neuropathic pain is caused by a disease or lesion of the somatosensory nervous system, and nociplastic pain is believed to be related to a sensitized nervous system (c.f. the concept of "central sensitization"). This also has implications concerning treatment. Some chronic pain conditions are nowadays viewed more as diseases rather than the pain being merely a symptom. In the new ICD-11 pain classification, this is conceptualized by the characterization of some chronic pains as "primary". Third, in addition to a conventional biomedical evaluation, psychosocial and behavioral aspects must also be assessed, the pain patient being viewed as an active agent and not merely as the passive recipient of an intervention. Hence, the importance of a dynamic bio-psycho-social perspective. The dynamic interplay of biological, psychological, and social aspects must be taken into account, putative behavioral "vicious circles" thereby being identified. Some core psycho-social concepts in pain medicine are mentioned. CONCLUSIONS The clinical applicability and clinical reasoning power of the 3 × 3 framework is illustrated by three short (albeit fictional) case descriptions.

The Efficacy of Acceptance and Commitment Therapy for Chronic Pain: A Systematic Review and Meta-analysis. Clin J Pain 2023; 39:147-157.

Abstract
OBJECTIVES Previous meta-analyses of a small number of trials showed that acceptance and commitment therapy (ACT) might improve chronic pain. Many new trials have been published afterward, and the factors that may impact the efficacy of ACT are less understood. We, therefore, conducted an updated systematic review with meta-analysis to investigate the efficacy of ACT for people with chronic pain. METHODS Randomized controlled trials that investigated the efficacy of ACT in clinical or community setting for adult populations with chronic pain were included. The methodological quality of trials was assessed with the Cochrane Risk of Bias tool. Standardized mean differences between ACT and comparison groups in their effects on 6 outcomes (ie, pain acceptance, quality of life, pain-related functioning, pain intensity, anxiety, and depression) were pooled across studies. RESULTS Of the 3171 records identified, 21 trials with 1962 participants were included for analysis. The comparison groups included active treatment and waitlist control/usual care. The standardized mean difference was 0.67 (95% CI: 0.48, 0.87) for pain acceptance, 0.43 (95% CI: 0.29, 0.57) for quality of life, -0.88 (95% CI: -1.14, -0.63) for pain-related functioning, -0.45 (95% CI: -0.62, -0.27) for pain intensity, -0.35 (95% CI: -0.54, -0.15) for anxiety, and -0.74 (95% CI, -0.98, -0.50) for depression, all favoring ACT. Subgroup analyses showed that the effects were statistically significant across almost all subgroups and for some outcomes were greater in the trials conducted in people with a specific diagnosis (as compared with those conducted in people with general chronic pain), the trials with waitlist or usual care control, the trials with a greater number of sessions of ACT, and the trials with a longer ACT intervention. DISCUSSION ACT is effective and comparable to, if not better than, some other available active treatments for chronic pain.

Abstract
OBJECTIVES To identify patient risk factors associated with prescription opioid misuse and abuse as well as groupings of misuse and abuse behaviors as measured by the Prescription Opioid Misuse and Abuse Questionnaire (POMAQ). METHODS Adults with chronic pain requiring long-term treatment with opioids completed the POMAQ and other study questionnaires. Latent class analysis (LCA) was used to examine underlying subgroups exhibiting particular risk profiles. Patient demographic and clinical characteristics were examined as covariates and the concordance between the identified latent classes at-risk classifications and the POMAQ clinical scoring algorithm was assessed. RESULTS Analysis of data from 809 patients revealed four classes: "chronic pain, low risk" (n = 473, low to no prevalence of POMAQ behaviors), "chronic pain, comorbid condition" (n = 152, high prevalence of anti-anxiety, sleeping pill, and antihistamine use), "at risk" (n = 154, taking more opioids than prescribed and drinking alcohol with opioids more frequently than other groups), and "high risk" (n = 30, highest prevalence of each behavior). The "high risk" group was associated with being younger, less educated, and unemployed compared to other groups. When examining the LCA classes by groups defined by the original POMAQ clinical scoring algorithm, the "high risk" class had the highest proportion of participants identified with abuse behaviors (46.7%), compared to just 4.7% in the "chronic pain, low risk" group. CONCLUSIONS Findings suggest there are four distinct subgroups of patients defined by chronic opioid misuse and abuse behaviors and support the use of the POMAQ to identify risk factors associated with prescription opioid misuse and abuse.

Efficacy and safety of anti-interleukin-1 therapeutics in the treatment of knee osteoarthritis: a systematic review and meta-analysis of randomized controlled trials. J Orthop Surg Res 2023; 18:100. [PMID: 36782214 PMCID: PMC9923921 DOI: 10.1186/s13018-023-03590-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Accepted: 02/07/2023] [Indexed: 02/15/2023] Open
Abstract
OBJECTIVE We aimed to evaluate the efficacy and safety of anti-interleukin-1 therapeutics, including IL-1 antibodies, interleukin-1 receptor antagonists (IL-1 Ras) and IL-1 inhibitors, for knee osteoarthritis (KOA) treatment. METHODS Databases (Medline, Embase, Web of Science and CENTRAL) and ClinicalTrials.gov were systematically searched for randomized controlled trials (RCTs) of anti-interleukin-1 therapeutics from inception to August 31, 2022. The outcomes were the mean change in pain and function scores and the risk of adverse effects (AEs). RESULTS In the 12 studies included, anti-interleukin-1 therapeutics were superior to placebo in terms of pain relief (standardized mean difference [SMD] = - 0.38, 95% confidence interval [CI] = - 1.82 to - 0.40, p < 0.001, I2 = 77%) and functional improvement (SMD = - 1.11, 95% CI = - 1.82 to - 0.40, p = 0.002, I2 = 96%). The incidence of any AE (risk ratio [RR] = 1.02, 95% CI = 0.88-1.18, p < 0.001, I2 = 76%) was higher following treatment with anti-interleukin-1 therapeutics than placebo, while no significant difference was found in the incidence of serious AEs (SAEs) or discontinuations due to AEs. Subgroup analyses showed that IL-1 antibodies and the IL-1 inhibitor provided pain relief (IL-1 antibodies: SMD = - 0.61, 95% CI = - 0.92 to - 0.31, p < 0.001; IL-1 inhibitor: SMD = - 0.39, 95% CI = - 0.72 to - 0.06, p = 0.02, I2 = 74.0%) and functional improvement (IL-1 antibodies: SMD = - 1.75, 95% CI = - 2.10 to - 1.40, p < 0.001; IL-1 inhibitor: SMD = - 0.28, 95% CI = - 0.83 to 0.27, p = 0.31, I2 = 88%) superior to those of placebo, whereas IL-1 Ras did not. However, the IL-1 inhibitor increased the incidence of any AE (RR = 1.35, 95% CI = 0.92-1.98, p < 0.001, I2 = 85%) but not the risk of SAEs or discontinuations due to AEs. IL-1 antibodies and IL-1 Ras showed no difference in safety compared with placebo. CONCLUSIONS Anti-interleukin-1 therapeutics could relieve OA-related pain and improve function, but is probably associated with an increased risk of adverse events. Specially, IL-1 antibodies and an IL-1 inhibitor could relieve OA-related pain and improve function, whereas IL-1 Ras could not. IL-1 antibodies and IL-1 Ras were relatively safe options, but IL-1 inhibitors were associated with safety concerns.

Moderators and Nonspecific Predictors of Treatment Benefits in a Randomized Trial of Mindfulness-Based Stress Reduction vs Cognitive-Behavioral Therapy vs Usual Care for Chronic Low Back Pain. THE JOURNAL OF PAIN 2023; 24:282-303. [PMID: 36180008 PMCID: PMC9898119 DOI: 10.1016/j.jpain.2022.09.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 09/12/2022] [Accepted: 09/15/2022] [Indexed: 02/06/2023]
Abstract
Both mindfulness-based stress reduction (MBSR) and cognitive-behavioral therapy (CBT) are effective for chronic low back pain (CLBP), but little is known regarding who might benefit more from one than the other. Using data from a randomized trial comparing MBSR, CBT, and usual care (UC) for adults aged 20 to 70 years with CLBP (N = 297), we examined baseline characteristics that moderated treatment effects or were associated with improvement regardless of treatment. Outcomes included 8-week function (modified Roland Disability Questionnaire), pain bothersomeness (0-10 numerical rating scale), and depression (Patient Health Questionnaire-8). There were differences in the effects of CBT versus MBSR on pain based on participant gender (P = .03) and baseline depressive symptoms (P = .01), but the only statistically significant moderator after Bonferroni correction was the nonjudging dimension of mindfulness. Scores on this measure moderated the effects of CBT versus MBSR on both function (P = .001) and pain (P = .04). Pain control beliefs (P <.001) and lower anxiety (P < .001) predicted improvement regardless of treatment. Replication of these findings is needed to guide treatment decision-making for CLBP. TRIAL REGISTRATION: The trial and analysis plan were preregistered in ClinicalTrials.gov (Identifier: NCT01467843). PERSPECTIVE: Although few potential moderators and nonspecific predictors of benefits from CBT or MBSR for CLBP were statistically significant after adjustment for multiple comparisons, these findings suggest potentially fruitful directions for confirmatory research while providing reassurance that patients could reasonably expect to benefit from either treatment.

Abstract
BACKGROUND Pain is a complex experience with both sensory and affective dimensions, and the affective dimension can increase the risks of chronic pain development. It is thus critical to identify factors influencing the affective dimension of pain. OBJECTIVE This study aimed to identify the relationship between the affective dimension of pain and disorder site (primary pain source). METHODS Study participants were recruited from patients referred for physical therapy at an orthopedic outpatient clinic. Pain quality including the affective dimension, disorder site from descriptive medical diagnosis, pain intensity, duration from pain onset, and demographic data, was collected. A multivariable logistic regression model was constructed to analyze the relationship between the affective dimension of pain and the disorder site. RESULTS A total of 282 participants were included. Cervical and lumbar spine disorders were significantly associated with an affective dimension of pain compared to limbs disorders when adjusted for age, sex, pain intensity, and duration from the onset in the regression model. CONCLUSIONS Regardless of duration from the onset and other confounding factors, disorder site is correlated with the affective dimension of pain. Multidimensional pain assessment is crucial when clinicians evaluate patients with cervical and lumbar spine disorders, even in the acute phase.

Abstract
The G protein-coupled P2Y12 receptor (P2Y12R) was cloned in platelets and found to play a key role in maintaining platelet function in hemostasis and thrombosis, and these effects could be mediated by the P2Y12R. However, it has recently been found that P2Y12R-mediated the progression of tumor through interactions between platelets and tumor and stromal cells, as well as through products secreted by platelets. During tumor progression, tumor cells or other cells in the tumor microenvironment (such as immune cells) can secrete large amounts of ATP into the extracellular matrix, and extracellular ATP can be hydrolyzed into ADP. ADP is a P2Y12R activator and plays an important regulatory role in the proliferation and metastasis of tumor cells. P2Y12R is involved in platelet-cancer cell crosstalk and become a potential target for anticancer therapy. Moreover, tumor progression can induce pain, which seriously affects the quality of life of patients. P2Y12R is expressed in microglia and mediates the activities of microglial and participates in the occurrence of cancer pain. Conversely, inhibiting P2Y12R activation and down-regulating its expression has the effect of inhibiting tumor progression and pain. Therefore, P2Y12R can be a common therapeutic target for both. In this article, we explored the potential link between P2Y12R and cancer, discussed the intrinsic link of P2Y12R in cancer pain and the pharmacological properties of P2Y12R antagonists in the treatment of both.

Abstract
The assessment and management of pain and nociception is very challenging in patients unable to communicate functionally such as patients with disorders of consciousness (DoC) or in locked-in syndrome (LIS). In a clinical setting, the detection of signs of pain and nociception by the medical staff is therefore essential for the wellbeing and management of these patients. However, there is still a lot unknown and a lack of clear guidelines regarding the assessment, management and treatment of pain and nociception in these populations. The purpose of this narrative review is to examine the current knowledge regarding this issue by covering different topics such as: the neurophysiology of pain and nociception (in healthy subjects and patients), the source and impact of nociception and pain in DoC and LIS and, finally, the assessment and treatment of pain and nociception in these populations. In this review we will also give possible research directions that could help to improve the management of this specific population of severely brain damaged patients.

Abstract
Managing pain is essential for social, psychological, physical, and economic reasons. It is also a human right with a growing incidence of untreated and under-treated pain globally. Barriers to diagnosing, assessing, treating, and managing pain are complicated, subjective, and driven by patient, healthcare provider, payer, policy, and regulatory challenges. In addition, conventional treatment methods pose their own challenges including the subjectivity of assessment, lack of therapeutic innovation over the last decade, opioid use disorder and financial access to treatment. Digital health innovations hold much promise in providing complementary solutions to traditional medical interventions and may reduce cost and speed up recovery or adaptation. There is a growing evidence base for the use of digital health in pain assessment, diagnosis, and management. The challenge is not only to develop new technologies and solutions, but to do this within a framework that supports health equity, scalability, socio-cultural consideration, and evidence-based science. The extensive limits to physical personal interaction during the Covid-19 pandemic 2020/21 has proven the possible role of digital health in the field of pain medicine. This paper provides an overview of the use of digital health in pain management and argues for the use of a systemic framework in evaluating the efficacy of digital health solutions.

Abstract
Background Adults with chronic pain have a lower quality of life (QOL) compared to the general population. Chronic pain requires specialized treatment to address the multitude of factors that contribute to an individual's pain experience, and effectively managing pain requires a biopsychosocial approach to improve patients' QOL. Aim This study examined adults with chronic pain after a year of specialized treatment to determine the role of cognitive markers (i.e., pain catastrophizing, depression, pain self-efficacy) in predicting changes in QOL. Methods Patients in an interdisciplinary chronic pain clinic (N = 197) completed measures of pain catastrophizing, depression, pain self-efficacy, and QOL at baseline and 1 year later. Correlations and a moderated mediation were completed to understand the relationships between the variables. Results Higher baseline pain catastrophizing was significantly associated with increased mental QOL (b = 0.39, 95% confidence interval [CI] 0.141; 0.648) and decreased depression (b = -0.18, 95% CI -0.306; -0.052) over a year. Furthermore, the relationship between baseline pain catastrophizing and the change in depression was moderated by the change in pain self-efficacy (b = -0.10, 95% CI -0.145; -0.043) over a year. Patients with high baseline pain catastrophizing reported decreased depression after a year of treatment, which was associated with greater QOL improvements but only in patients with unchanged or improved pain self-efficacy. Conclusions Our findings highlight the roles of cognitive and affective factors and their impact on QOL in adults with chronic pain. Understanding the psychological factors that predict increased mental QOL is clinically useful, because medical teams can optimize these positive changes in QOL through psychosocial interventions aimed at improving patients' pain self-efficacy.

[PMID: 36606031 PMCID: PMC9807876 DOI: 10.3389/fpain.2022.1067103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Accepted: 12/06/2022] [Indexed: 12/24/2022]
Abstract
A thorough pain assessment is of utmost importance when managing pain in clinical practice as it is the foundation for defining pain in need of treatment, either interventional or pharmacological. Pain characteristics can also guide interventional strategies and help evaluate the effect of treatment. In research settings, standardized pain assessment is crucial to improve comparability across studies and facilitate meta-analysis. Due to the importance of thorough visceral pain assessment, this manuscript describes the key elements of pain evaluation focusing on chronic pancreatitis. Most studies in pain assessment have focused on somatic pain, and although chronic pain often shares characteristics between etiologies, some differences must be addressed when assessing visceral pain. Especially differences between somatic and visceral pain are apparent, where visceral pain is diffuse and difficult to localize, with referred pain aspects and often autonomic symptoms dominating the clinical picture. These aspects need to be incorporated into the pain assessment instrument. The manuscript will discuss the different ways of assessing pain, including unidimensional measurement scales, multidimensional questionnaires, and quantitative sensory testing. The advantages and challenges linked to the different methods will be evaluated.
