Chronic pain in the 11th revision of the International Classification of Diseases: users' questions answered. Pain 2021; 163:1675-1687. [PMID: 34862338 DOI: 10.1097/j.pain.0000000000002551] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Accepted: 11/30/2021] [Indexed: 11/27/2022]
Abstract
ABSTRACT The upcoming 11th revision of the International Classification of Diseases (ICD-11) will include a comprehensive classification of chronic pain for the first time, which is based on the biopsychosocial definition of chronic pain. This presents a great opportunity for pain research and clinical practice. The new classification consists of seven main diagnostic categories of chronic pain, which are further divided into increasingly specific levels of diagnoses. Each diagnosis is characterized by clearly defined operationalized criteria. Future users will need to familiarize themselves with the new system and its application. The aim of the present publication is to provide users of the ICD-11 chronic pain classification with answers to frequently asked questions regarding the ICD-11 as a whole, the ICD-11 chronic pain classification, and its application to common pain syndromes. The questions compiled here reached the International Association for the Study of Pain Task Force via different routes (e.g., at conferences, by letter, or during field testing). Furthermore, the authors collected questions posted to the ICD-11 browser and contacted early users of the classification to enquire about their most frequent difficulties when applying the new diagnoses. The authors of the present publication prepared answers to these frequently asked questions. This publication intends to act as a guide for the future users of the new ICD-11 chronic pain classification, hence facilitating its implementation.

Abstract
The increasing number of cancer survivors associated to a longer average life-span after diagnosis of an oncological disease facilitates the observation of deleterious long-term effects of both oncological disease and its treatment. Among these effects, chronic pain emerges as one of the most prevalent and, with its onset, there is a decrease in these patients' functionality and quality of life. The main focus in oncological disease treatment has been tumour eradication and average life expectancy extension after diagnosis, neglecting these deleterious long-term effects. This study aims at assessing the prevalence and characteristics of chronic pain in cancer survivors as well as pain interference in their quality of life and functionality. The study selected cancer survivors (n = 85) after dismissal from oncology service to assess the presence and characteristics of chronic pain, their health-related quality of life (HRQoL) and pain-related disability through a combination of different questionnaires. Chronic pain prevalence was 23.5%. In total, 85% of patients reported neuropathic pain descriptors and 45% presented diagnostic criteria for neuropathic pain. Of these patients, 45% were followed-up for pain surveillance and 35% underwent analgesic medication. There was a median pain disability index of 20.50 (14.50-35.00) and an average HRQoL of 0.5338 in chronic pain patients and 0.8872 in patients without pain. We found that chronic pain was the main negative predictor of HRQoL and was associated with decreased functionality. This study also concluded that these patients often were not offered the appropriate long-term medical follow-up. These findings highlight a need to raise awareness among health professionals to the importance of timely diagnosis and treatment of pain and its impact on HRQoL and functionality of long-term cancer survivors as well as the need to change clinical practice in order to improve healthcare provided to these patients.

Abstract
Cancer pain remains a major public health issue. Despite progress in pain medicine thanks to the interest shown in early and timely supportive care, more than half the patients managed for cancer are in pain. One of the key factors in high quality multidisciplinary management throughout the care pathway is to assess more than just pain: it is necessary to assess the patient as a whole. Understanding the complexity of cancer pain - or the various types of pain - through the innovative multimorphic cancer pain model, effectively opens up new perspectives for a targeted, personalised, and multimodal approach. The subsequent treatment strategies, whether drug-based with opioids, or interventional, are codified by guidelines based on scientific evidence for the healthcare professionals and, ultimately, patients.

Abstract
Traditional Chinese medicine (TCM), especially Chinese herbal medicines and acupuncture, has been traditionally used to treat patients with cancers in China and other East Asian countries. Numerous studies have indicated that TCM not only alleviates the symptoms (e.g., fatigue, chronic pain, anorexia/cachexia, and insomnia) of patients with cancer and improves their quality of life (QOL) but also diminishes adverse reactions and complications caused by chemotherapy, radiotherapy, or targeted-therapy. Therefore, Chinese herbal medicines and acupuncture and other alternative therapies need to be understood by TCM physicians and other health care providers. This review mainly summarizes the experimental results and conclusions from literature published since 2010, and a search of the literature as been performed in the PubMed, MEDLINE, Web of Science, Scopus, Springer, ScienceDirect, and China Hospital Knowledge Database (CHKD) databases. Some Chinese herbal medicines (e.g., Panax ginseng, Panax quinquefolius, Astragali radix, Bu-zhong-yi-qi-tang (TJ-41), Liu-jun-zi-tang (TJ-43), Shi-quan-da-bu-tang (TJ-48), and Ban-xia-xie-xin-tang (TJ-14)) and some acupuncture points (e.g., Zusanli (ST36), Zhongwan (CV12), Neiguan (PC6) and Baihui (GV20)) that are commonly used to treat cancer-related symptoms and/or to reduce the toxicity of chemotherapy, radiotherapy, or targeted-therapy are highlighted and summarized. Through a review of literature, we conclude that TCM can effectively alleviate adverse gastrointestinal reactions (including diarrhea, nausea, and vomiting) to these anti-cancer therapies, decrease the incidence of bone marrow suppression, alleviate cardiotoxicity, and protect against chemotherapy-induced peripheral neuropathy and radiation-induced pneumonitis. Moreover, TCM can alleviate epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI)-related acneiform eruptions, diarrhea, and other adverse reactions. The hope is that this review can contribute to an understanding of TCM as an adjuvant therapy for cancer and that it can provide useful information for the development of more effective anti-cancer therapies. However, more rigorously designed trials involving cancer treatment must be conducted in the future, including complete quality control and standardized models at the cellular, organic, animal and clinical levels, in order to study TCM in multiple forms and at multiple levels.

Abstract
OBJECTIVES Musculoskeletal pain is common among children and adolescents. Despite the lack of evidence regarding harms and benefits, musculoskeletal pain is often managed with pain medication. The aim of this systematic review is to assess the prevalence of pain medication use for musculoskeletal pain among children and adolescents and the factors and side effects associated with use. CONTENT Three databases (EMBASE, CINAHL and PsychINFO) were systematically searched to identify studies designed to examine the prevalence, frequency or factors associated with the use of pain medication for musculoskeletal pain in children and adolescents (aged 6-19 years). The included studies were assessed for study quality and data were extracted. SUMMARY The search initially provided 20,135 studies. After screening titles, abstracts and full-texts, 20 studies were included. In school settings, 8-42% of children used pain medication for musculoskeletal pain, and 67-75% of children in sports clubs and from pain clinics used pain medication. The most consistent factors associated with the use of pain medications were pain characteristics and psychological factors (e.g. being bullied, low-self-esteem), while mixed evidence was found for increasing age and female gender. Only two studies reported on the duration of use and only one study on adverse effects related to the use of pain medication. OUTLOOK We found that 8-42% of adolescents from school-based samples use pain medication for MSK pain, while the prevalence among adolescents from sports clubs and pain clinics is higher (67-75%). Pain characteristics (pain duration, severity, intensity, disability levels and the presence of ≥2 pain conditions or multisite pain) and psychological factors were associated with a higher use of pain medication, while for higher age and female gender the evidence of association was mixed. Future studies should systematically collect information on the type, duration of use of pain medication and side effects to confirm the findings of this review.

Abstract
Purpose Evaluation of symptoms and signs for the management of neuropathic cancer pain (NCP) is challenging. This study aimed to identify clinical predictors of NCP and symptoms and signs most relevant of those in Korean patients. Methods This nationwide, descriptive, cross-sectional, multicenter, observational study included 2,003 cancer patients aged ≥20 years who reported a visual analog scale (VAS) score ≥1 for pain and provided informed consent for participation. The Douleur Neuropathic (DN4) questionnaire (score ≥4) was used to determine symptoms and signs as well as the presence of NCP. Results The prevalence of NCP was associated with age <65 years [OR, 1.57; 95% CI, 1.270–1.934], disease duration >6 months (OR, 1.57; 95% CI, 1.232–2.012), stage IV cancer (OR, 0.75; 95% CI, 0.593–0.955), history of chemotherapy (OR, 1.74; 95% CI, 1.225–2.472), and moderate-to-severe cancer pain (OR, 2.05; 95% CI, 1.671–2.524) after multivariate analysis. The most common descriptive symptoms of NCP were tingling, electric shock, and pins and needles. For NCP patients in the presence or absence of the clinical predictors, pins and needles (p = 0.001) and painful cold (p<0.001) symptoms were significantly frequent in patients with moderate-to-severe pain. Tingling, numbness, and touch hypoesthesia (p = 0.022, 0.033, 0.024, respectively) were more frequent in those with longer cancer duration and hyperesthesia (p = 0.024) was more frequent in young patients. Conclusion Age <65 years, disease duration >6 months, stage IV cancer, history of chemotherapy, and moderate-to-severe cancer pain, were identified as predictors of NCP. Some symptoms and signs of NCP were associated with these predictors. Further studies are warranted on the pathogenesis and management of NCP with respect to the symptoms and signs, and factors associated with pain severity in Korean patients.

Multidimensional Statistical Technique for Interpreting the Spontaneous Breakthrough Cancer Pain Phenomenon. A Secondary Analysis from the IOPS-MS Study. Cancers (Basel) 2021; 13:cancers13164018.

Abstract
Breakthrough cancer pain (BTcP) is a temporary exacerbation of pain that "breaks through" a phase of adequate pain control by an opioid-based therapy. The non-predictable BTcP (NP-BTcP) is a subtype of BTcP that occurs in the absence of any specific activity. Since NP-BTcP has an important clinical impact, this analysis is aimed at characterizing the NP-BTcP phenomenon through a multidimensional statistical technique. This is a secondary analysis based on the Italian Oncologic Pain multiSetting-Multicentric Survey (IOPS-MS). A correlation analysis was performed to characterize the NP-BTcP profile about its intensity, number of episodes per day, and type. The multiple correspondence analysis (MCA) determined the identification of four groups (phenotypes). A univariate analysis was performed to assess differences between the four phenotypes and selected covariates. The four phenotypes represent the hierarchical classification according to the status of NP-BTcP: from the best (phenotype 1) to the worst (phenotype 4). The univariate analysis found a significant association between the onset time >10 min in the phenotype 1 (37.3%)' vs. the onset > 10 min in phenotype 4 (25.8%) (p < 0.001). Phenotype 1 was characterized by the gastrointestinal type of cancer (26.4%) with respect to phenotype 4, where the most frequent cancer affected the lung (28.8%) (p < 0.001). Phenotype 4 was mainly managed with rapid-onset opioids, while in phenotype 1, many patients were treated with oral, subcutaneous, or intravenous morphine (56.4% and 44.4%, respectively; p = 0.008). The ability to characterize NP-BTcP can offer enormous benefits for the management of this serious aspect of cancer pain. Although requiring validation, this strategy can provide many indications for identifying the diagnostic and therapeutic gaps in NP-BTcP management.

Abstract
BACKGROUND AND OBJECTIVE Mindfulness-based interventions (MBIs) have been recently applied in pain management and cancer care. However, inconsistencies exist concerning the effectiveness of MBIs on pain control among cancer patients. Therefore, this study aimed to examine the efficacy of MBIs on pain in cancer patients via a systematic review and meta-analysis of randomized controlled trials (RCTs). METHODS Databases (MEDLINE, PubMed, Embase, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov) were searched using key terms related to pain, cancer and mindfulness. The primary outcome was pain intensity. Standardized mean difference (SMD) of each outcome with 95% confidence interval (95% CI) was calculated. The quality of evidence was assessed by GRADE assessment. RESULTS Ten RCTs with 843 participants were included. Significant pooled effects of MBIs on pain intensity were found at both short-term (SMD = -0.19, 95% CI [-0.33 to -0.04]) and long-term (SMD = -0.20, 95% CI [-0.35 to -0.05]) follow-up, whereas no significance was observed for pain interference. In subgroup analyses, significant intervention effects were only seen in clinic-based MBIs compared to remote MBIs, and pooled effects of MBIs in attenuating pain were discovered relative to passive rather than active comparators. GRADE ratings showed moderate certainty of evidence in MBIs for pain intensity but low for pain interference. CONCLUSIONS The efficacy of MBIs in reducing pain intensity among cancer patients was revealed in this meta-analysis, albeit with a small effect size. Future research is warranted to optimize mindfulness treatment for pain control in cancer patients with high methodological quality and a large sample size. SIGNIFICANCE The effect of MBIs on pain in cancer patients was demonstrated in our analysis, albeit with small effect sizes. High-quality RCTs are needed to verify the efficacy of MBIs on cancer patients or survivors with pain complaints. Future trials should take into account the specific pain outcome measures (pain intensity or pain interference), the approach of intervention provision (clinic-based or remote MBI, group or individual practice), the duration and frequency of interventions and the comparators (passive or active control arms).

Abstract
PURPOSE OF REVIEW An overview on breakthrough cancer pain (BTCP), including inherent limitations of the terminology, assessment, clinical presentation, and treatment options. RECENT FINDINGS The estimated prevalence of BTCP is dependent on the defined cutoffs for controlled background pain and the magnitude of the pain flare. In addition, pain flares outside the definition of BTCP are prevalent. In the 11th Revision of the International Classification of Diseases, the temporal characteristics of cancer pain are described as continuous background pain and intermittent episodic pain. BTCP should be assessed by validated methods, and the patient perspective should be included. The pain may be related to neoplastic destruction of bone, viscera, or nerve tissue and is characterized by rapid onset, high intensity, and short duration. Treatment directed towards painful metastases must be considered. Due to pharmacological properties mirroring the pain characteristics, transmucosal fentanyl formulations are important for the treatment of BTCP. Oral immediate release opioids can be used for slow-onset or predictable BTCP. For more difficult pain conditions, parenteral, or even intrathecal pain medication, may be indicated. SUMMARY All clinically relevant episodic pains must be adequately treated in accordance with the patient's preferences. Transmucosal fentanyl formulations are effective for BTCP.

Abstract
PURPOSE Pain management principles vary considerably between chronic noncancer, acute and cancer pain. Cancer patients responding to oncological treatment may live with low tumor burden for years. Opioid treatment should reflect that the ratio between benefits and risks in these patients is different from patients with a rapidly progressive disease. Our study investigated the prescription patterns of analgesics in patients who died 6 to 9 years after cancer diagnosis. PATIENTS AND METHODS A pharmaco-epidemiological study based on the Norwegian Prescription Database and Cancer Registry of Norway. The 1-year periodic prevalence of receiving different analgesics and of persistent opioid use were analyzed. Persistent opioid use was defined as >365 Defined Daily Doses or >9000 mg Oral Morphine Equivalents during 365 days with prescriptions in all quarters of the 365 days period. Data were reported for the first 7 years for patients who lived 8-9 years after cancer diagnosis (N = 1502), while for patients who lived 6-7 years (N = 3817) data was reported for the first 5 years after diagnosis. RESULTS Compared to age- and gender adjusted general population, the 1-year periodic prevalence of opioid prescription was doubled the first year after diagnosis and remained raised with approximately 50%. The prevalence of persistent opioid use was threefold of the general population. Approximately 55% of patients with persistent opioid use 4 years after a cancer diagnosis were co-medicated with high doses of benzodiazepines and/or benzodiazepine-related hypnotics. CONCLUSION The findings of increased opioid use raise concerns regarding whether the benefits outweigh risks and side effects in this population.

Abstract
Tetrodotoxin (TTX) is a potent neurotoxin found mainly in puffer fish and other marine and terrestrial animals. TTX blocks voltage-gated sodium channels (VGSCs) which are typically classified as TTX-sensitive or TTX-resistant channels. VGSCs play a key role in pain signaling and some TTX-sensitive VGSCs are highly expressed by adult primary sensory neurons. During pathological pain conditions, such as neuropathic pain, upregulation of some TTX-sensitive VGSCs, including the massive re-expression of the embryonic VGSC subtype NaV1.3 in adult primary sensory neurons, contribute to painful hypersensitization. In addition, people with loss-of-function mutations in the VGSC subtype NaV1.7 present congenital insensitive to pain. TTX displays a prominent analgesic effect in several models of neuropathic pain in rodents. According to this promising preclinical evidence, TTX is currently under clinical development for chemo-therapy-induced neuropathic pain and cancer-related pain. This review focuses primarily on the preclinical and clinical evidence that support a potential analgesic role for TTX in these pain states. In addition, we also analyze the main toxic effects that this neurotoxin produces when it is administered at therapeutic doses, and the therapeutic potential to alleviate neuropathic pain of other natural toxins that selectively block TTX-sensitive VGSCs.

C-Reactive Protein and Its Relationship with Pain in Patients with Advanced Cancer Cachexia: Secondary Cross-Sectional Analysis of a Multicenter Prospective Cohort Study. Palliat Med Rep 2021; 2:122-131. [PMID: 34223511 PMCID: PMC8241396 DOI: 10.1089/pmr.2021.0004] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/12/2021] [Indexed: 02/06/2023] Open
Abstract
Background: Limited information is available on the relationship between C-reactive protein (CRP) levels and pain in advanced cancer. Objectives: To investigate the relationship between serum levels of CRP and subtypes of pain. Design: A secondary cross-sectional analysis of a prospective cohort study. Setting/Subjects: Patients with advanced cancer admitted to 23 palliative care units in Japan. Measurements: Patients rated the severity of pain on the numerical rating scale (NRS) and physicians evaluated pain on the integrated palliative care outcome scale (IPOS). Physicians assessed neuropathic pain and breakthrough pain based on their presence or absence. Patients were divided into four groups according to CRP levels. Comparisons were performed using the Kruskal–Wallis test or chi-squared test. To evaluate the relationship between CRP and subtypes of pain, adjusted odds ratios (ORs) and 95% confidence intervals (CIs) in logistic models were calculated. Results: We divided 1513 patients into four groups: low CRP (n = 234), moderate CRP (n = 513), high CRP (n = 352), and very high CRP (n = 414). Spearman's correlation coefficient between CRP and pain NRS and that between CRP and pain IPOS were 0.15 (p < 0.001) and 0.16 (p < 0.001), respectively. In the models of pain NRS and pain IPOS, significantly higher adjusted ORs than in the low CRP group were observed in the very high CRP group (1.81 [95% CI 1.14–2.88], p = 0.01; 1.74 [95% CI 1.18–2.57], p = 0.005, respectively). Relationships were not observed between CRP, neuropathic pain, and breakthrough pain. Conclusions: The results indicated direct relationships between CRP, pain NRS, and pain IPOS.

Abstract
ABSTRACT The International Classification of Diseases-11 (ICD-11) chronic pain classification includes about 100 chronic pain diagnoses on different diagnostic levels. Each of these diagnoses requires specific operationalized diagnostic criteria to be present. The classification comprises more than 200 diagnostic criteria. The aim of the Classification Algorithm for Chronic Pain in ICD-11 (CAL-CP) is to facilitate the use of the classification by guiding users through these diagnostic criteria. The diagnostic criteria were ordered hierarchically and visualized in accordance with the standards defined by the Society for Medical Decision Making Committee on Standardization of Clinical Algorithms. The resulting linear decision tree underwent several rounds of iterative checks and feedback by its developers, as well as other pain experts. A preliminary pilot evaluation was conducted in the context of an ecological implementation field study of the classification itself. The resulting algorithm consists of a linear decision tree, an introduction form, and an appendix. The initial decision trunk can be used as a standalone algorithm in primary care. Each diagnostic criterion is represented in a decision box. The user needs to decide for each criterion whether it is present or not, and then follow the respective yes or no arrows to arrive at the corresponding ICD-11 diagnosis. The results of the pilot evaluation showed good clinical utility of the algorithm. The CAL-CP can contribute to reliable diagnoses by structuring a way through the classification and by increasing adherence to the criteria. Future studies need to evaluate its utility further and analyze its impact on the accuracy of the assigned diagnoses.

Abstract
Immune checkpoint inhibitors (ICIs) are the standard of care for the treatment of several cancers. While these immunotherapies have improved patient outcomes in many clinical settings, they bring accompanying risks of toxicity, specifically immune-related adverse events (irAEs). There is a need for clear, effective guidelines for the management of irAEs during ICI treatment, motivating the Society for Immunotherapy of Cancer (SITC) to convene an expert panel to develop a clinical practice guideline. The panel discussed the recognition and management of single and combination ICI irAEs and ultimately developed evidence- and consensus-based recommendations to assist medical professionals in clinical decision-making and to improve outcomes for patients.

Abstract
Chronic pain has been widely recognized as a major public health problem that impacts multiple aspects of patient quality of life. Unfortunately, chronic pain is often resistant to conventional analgesics, which are further limited by their various side effects. New therapeutic strategies and targets are needed to better serve the millions of people suffering from this devastating disease. To this end, recent clinical and preclinical studies have implicated the epidermal growth factor receptor signaling pathway in chronic pain states. EGFR is one of four members of the ErbB family of receptor tyrosine kinases that have key roles in development and the progression of many cancers. EGFR functions by activating many intracellular signaling pathways following binding of various ligands to the receptor. Several of these signaling pathways, such as phosphatidylinositol 3-kinase, are known mediators of pain. EGFR inhibitors are known for their use as cancer therapeutics but given recent evidence in pilot clinical and preclinical investigations, may have clinical use for treating chronic pain. Here, we review the clinical and preclinical evidence implicating EGFR in pathological pain states and provide an overview of EGFR signaling highlighting how EGFR and its ligands drive pain hypersensitivity and interact with important pain pathways such as the opioid system.

Abstract
There are limited data regarding long-term safety and efficacy in cancer survivors receiving chronic opioid therapy. With conflicting recommendations on opioid-prescribing practices and lack of available outcome data, this study aimed to provide a longitudinal perspective on opioid prescribing in cancer survivors. A retrospective chart review at a comprehensive cancer care center pain clinic used data from pain clinic provider notes from 2013 to 2018. Inclusion criteria were patients in clinical remission not receiving active chemotherapy or immunotherapy and receiving opioids during the study period. Opioid dosing changes and outcomes between zero and five years were evaluated by standard statistical analysis. Thirty-two patients met inclusion criteria. Solid malignancies were more common than hematologic malignancies (72% vs. 28%). Common pain complaints were related to postsurgical changes (43%), postradiation (32%), and chemotherapy-induced pain syndromes (25%). There were no serious adverse events. One patient exhibited possible aberrant behavior. At the initial visit, the median morphine milligram equivalent per day (MME/day) was 130. Median MME/day at Year 0 (study start) and Year 5 was 135 and 159, respectively (P = 0.475). Functional status was satisfactory in 58% at Year 0 and increased to 91% of patients meeting their functional goals at Year 5. In a carefully monitored group of cancer survivors with persistent pain, chronic opioid therapy was safely managed during extended periods without significant opioid escalation or evidence of serious adverse events including aberrant behaviors. This population benefited when opioid therapy was managed with a focus on function rather than reduction of pain intensity scores.

Abstract
Pain is a common symptom in cancer patients. It is subjective and difficult to communicate. It continues to be outsourced and often overlooked despite the existence of multiple recommendations. The objective of this study is to describe pain management in cancer patients in a Tunisian hospital. This is a prospective study, conducted over one month at the maternity centre of Monastir by an intern in pharmacy using a questionnaire. Of 128 patients assessed, 50 were algic. Twenty-six percent of algic patients were not treated. The neuropathic component of pain was present in 30 % of cases but under treatment. Relief opioids were prescribed in 43 % of cases to relieve pain. Paracetamol was prescribed in 26 % of cases. Ten percent of patients use paracetamol self-medication. Sixteen percent of patients have tried non-pharmacological means, of which 62 % consume plants. To optimise the management of pain at our centre, the available analgesic sheets have been developed, validated by the medical staff and disseminated in the departments of carcinology and oncohematology. Therapeutic education sessions were also scheduled to warn patients about the risks of self-medication and misuse of medicinal plants. Pain management is complex. It requires respect for international recommendations, but especially for the efforts made by all stakeholders.

Abstract
ABSTRACT Neuropathic cancer pain (NcP) is associated with worse treatment responses and specific therapy indications, but a standardized clinical diagnosis of NcP is still lacking. This is a prospective observational study on outpatients with cancer, comparing different clinical approaches with NcP evaluation. A three-step assessment of NcP was performed using DN4 (cutoff of 4), palliative care physician Clinical Impression, including etiology and pain syndrome identification, and Retrospective Clinical Classification by a board of specialists with the IASP Neuropathic Pain Special Interest Group criteria. Neuropathic cancer pain classification was specifically referred to pain directly due to cancer. Three hundred fifty patients were assessed, and NcP prevalence was 20% (95% confidence interval [CI] 15.9%-24.6%), 36.9%, (95% CI 31.6%-42.1%), and 28.6% (95% CI 23.8%-33.9%) according to DN4, Clinical Impression, and Retrospective Clinical Classification, respectively. Cohen's kappa concordance coefficient between DN4 and Retrospective Clinical Classification was 0.57 (95% CI 0.47-0.67), indicating moderate concordance. Higher percentages of discordance were found for specific pain syndromes such as pain due to deep soft tissue infiltration and pain associated with tenesmus. Disagreement among clinicians accounted also for different NcP diagnoses and highlighted lack of homogeneous clinical criteria. Rigorous application of etiological and syndrome diagnosis to explain pain cause, associated with standardized diagnostic criteria and assessment of pain characteristics, that is also specific for the cancer pain condition could improve clinical classification of NcP.

Abstract
CONTEXT The International Association for the Study of Pain (IASP) defines chronic pain as pain that persists or recurs for longer than 3 months. Chronic pain has a significant global disease burden with profound effects on health, quality of life, and socioeconomic costs. EVIDENCE ACQUISITION Narrative review. RESULTS There are several treatment options, including pharmacological therapy, physical rehabilitation, psychological therapies, and surgical interventions, for chronic pain management. Magnesium has been FDA-approved for several indications including hypomagnesemia, arrhythmia, prevention of seizures in eclampsia/preeclampsia, and constipation. Magnesium has been used for numerous off-label uses, notably for acute and chronic pain management. The mechanism of magnesium in pain management is primarily through its action as a voltage-gated antagonist of NMDA receptors, which are involved in pain transduction. CONCLUSIONS This narrative review will focus on the current evidence and data surrounding the utilization of magnesium as a treatment option for chronic pain.

Abstract
The incidence of pain in cancer patients during diagnosis and treatment is exceedingly high. Although advances in cancer detection and therapy have improved patient prognosis, cancer and its treatment-associated pain have gained clinical prominence. The biological mechanisms involved in cancer-related pain are multifactorial; different processes for pain may be responsible depending on the type and anatomic location of cancer. Animal models of cancer-related pain have provided mechanistic insights into the development and process of pain under a dynamic molecular environment. However, while cancer-evoked nociceptive responses in animals reflect some of the patients’ symptoms, the current models have failed to address the complexity of interactions within the natural disease state. Although there has been a recent convergence of the investigation of carcinogenesis and pain neurobiology, identification of new targets for novel therapies to treat cancer-related pain requires standardization of methodologies within the cancer pain field as well as across disciplines. Limited success of translation from preclinical studies to the clinic may be due to our poor understanding of the crosstalk between cancer cells and their microenvironment (e.g., sensory neurons, infiltrating immune cells, stromal cells etc.). This relatively new line of inquiry also highlights the broader limitations in translatability and interpretation of basic cancer pain research. The goal of this review is to summarize recent findings in cancer pain based on preclinical animal models, discuss the translational benefit of these discoveries, and propose considerations for future translational models of cancer pain.

Abstract
Abstract
Objectives
Inadequate management of cancer pain (CP) remains a global medical problem. In this study, the aim was to assess attitudes of cancer patients towards their CP treatment and to evaluate effectiveness of pain management.
Methods
A sample of 300 adult cancer patients admitted to a single hospital were face-to-face interviewed in a cross-sectional study design using a structured questionnaire. The short form of the Brief Pain Inventory was used to collect data on pain, and Pain Management Index (PMI) was calculated to assess adequacy of pain management.
Key findings
Median age of patients was 53 years (interquartile range, 43–63). Half of patients (50.5%) believed their pain therapy needs improvement. Almost half patients had severe pain at interview (49.8%). Pain interfered most with patient enjoyment of life with a mean interference score 6.13 ± 2.37. Majority of cancer patients (84.3%) received a non-opioid analgesic while a minority (15.7%) received opioid analgesic in which morphine was the most common drug. The use of non-opioid adjuvants was minimal. Mean PMI for patients was −1.15 ± 0.75 (range −2 to +1), and most patients (80.3%) had inadequate pain treatment. Gender and smoking status of patients were significantly associated with adequacy of pain management (P = 0.009 and P = 0.004, respectively). There were no associations between patient age, educational level or tumour characteristics and adequacy of pain management.
Conclusions
Cancer patients in this study present with severe pain and the rates of undertreatment are high. There is an urgent need to improve management plans to assure appropriate use of therapeutic modalities for treatment of cancer-related pain.

Abstract
OBJECTIVES Chronic non-malignant pain (CNP) is a significant healthcare problem with considerable consequences for patients, relatives and society. CNP is a lifelong condition that calls for acceptance and self-management. Existing research indicates that the involvement of relatives improves patients' and relatives' management of CNP, but the area is, at present, scarcely described. Research is required to obtain knowledge about the patients' experiences, needs and preferences concerning the involvement of their relatives within the frame of CNP rehabilitation, which is the aim of this study. METHODS The study applied a qualitative phenomenological-hermeneutic design conducting individual interviews with 10 patients with CNP from three selected Multidisciplinary Pain Centres (MPC). The analysis was guided by Paul Ricoeur's philosophy of interpretation of the text. RESULTS The findings illuminated the patients' perspectives on the involvement of relatives within three key themes, each having two or three sub-themes. The analysis revealed that patients in CNP rehabilitation had various interpretations of the substance of involving relatives, reflecting their sparse experiences. It seemed arbitrary, who during the rehabilitation actually experienced the involvement of their relatives, leaving the impression of an area short of structure. This shortage was troublesome, due to a heartrending impact of CNP. Patients' reduced functional level, combined with their surroundings difficulties in grasping the magnitude of CNP led to a loss of relationships and a risk of social isolation. Patients' close relationships became essential but were under pressure as well. Patients living with a spouse/cohabitant experienced that the relationship was affected by a disrupted balance and pain-related emotional outbursts. The patients experienced a profound need for being understood, but the text also revealed a need for mutual understanding to acknowledge the relatives' strain as well. Particular patients with children living at home experienced to be under great strain, complicated by a deep concern for long-term consequences for their children growing up influenced by parental CNP. Experienced involvement of relatives, even to a minor extend was perceived as beneficial for the patients, who experienced increased understanding and support from the relatives. However, due to the lack of a structured service, the patients' access to the involvement of relatives became dependent on their ability to define their need and pick it out. Thus the patients also expressed a general preference for mandatory and structured involvement, yet tailored to the specific patient. CONCLUSIONS The study showed an overwhelming need for the involvement of relatives among patients with CNP, indicating that increased attention and investigation of relevant interventions are required. Despite differences between the MPC, our primary impression was that the involvement of relatives reached a minimal level of what was expected, which might entail desertion of patients scarce of resources. Individualised adjusted involvement of relatives is assumed to improve patient's management of CNP in everyday life. A family systems nursing (FSN) approach is a relevant proposal for intervention, useful in other illness areas. Still, research needs to shed light on the appropriateness of FSN when involving relatives in the rehabilitation of CNP.

Abstract
Chronic pain is considered a public health priority by the World Health Organization and European health institutions. It has reached alarming proportions in terms of disability, consumption of health and social resources, and impact on primary and specialist care services. Primary care physicians are often called on to manage this condition. Chronic pain management can be challenging due to its complexity. It has traditionally been considered to include nociceptive pain that that persists longer than the normal healing time, neuropathic pain lasting more than 3 months, or a combination of these. More recently, a third descriptor, nociplastic (primary) pain, was added to classify patients with chronic pain conditions such as fibromyalgia, nonspecific back pain, or mixed pain that persists or other conditions in which altered central pain modulation results in central sensitization and chronic pain in the absence of actual or threatened damage to tissues, including in the somatosensory nervous system. This document provides an overview of pain types and their underlying mechanisms. Successful pain management is facilitated by identification of the pain type. A set of diagnostic tools and a pain algorithm are presented to guide the clinician toward the correct diagnosis. The algorithm identifies cases that may require referral to a pain specialist. Once the site of origin of the pain (the "pain generator") is identified, or a primary pain syndrome is suspected, the accompanying article provides information and rationale to support treatment decisions based on patient characteristics.

Abstract
Croton zehntneri is a plant known as canelinha de cunhã, prevalent in the northeast region of Brazil. Many constituents of the vegetable have already been studied, and their pharmacological properties have been proven, but this is the first study to analyze the antinociceptive effect in adult zebrafish (ZFa) of the triterpene acetyl aleuritolic acid (AAA) isolated from the stem bark. The animals (ZFa; n = 6/group) were treated intraperitoneally (ip; 20 μL) with AAA (0.1 or 0.3 or 1.0 mg/mL) or vehicle (0.9% saline; 20 μL), and submitted to the locomotor activity test, as well as 96 h acute toxicity. Other groups (n = 6/each) received the same treatments and underwent acute nociception tests (formalin, cinnamaldehyde, glutamate, acid saline, capsaicin, and hypertonic saline). Possible neuromodulation mechanisms were evaluated. AAA (0.1 or 0.3 or 1.0 mg/mL) reduced the nociceptive behavior induced by acid saline and capsaicin, as well as inhibited corneal nociception induced by hypertonic saline, both without altering the animals' locomotor system and without toxicity. These analgesic effects of AAA were significantly (p > 0.05) similar to those of morphine, used as a positive control. The antinociceptive effect of AAA was inhibited by methylene blue, ketamine, camphor, ruthenium red, amiloride, and mefenamic acid. The antinociceptive effect of AAA on the cornea of animals was inhibited by capsazepine. Therefore, AAA showed pharmacological potential for the treatment of acute pain, and this effect is modulated by cGMP, NMDA receptors, transient receptor potential channels (TRPs), ASICs and has pharmacological potential for the treatment of corneal pain modulated by the TRPV1 channel.

Abstract
Neuropathic pain in children can be severe and persistent, difficult to recognise and manage, and associated with significant pain-related disability. Recognition based on clinical history and sensory descriptors is challenging in young children, and screening tools require further validation at older ages. Confirmatory tests can identify the disease or lesion of the somatosensory nervous system resulting in neuropathic pain, but feasibility and interpretation may be influenced by age- and sex-dependent changes throughout development. Quantitative sensory testing identifies specific mechanism-related sensory profiles; brain imaging is a potential biomarker of alterations in central processing and modulation of both sensory and affective components of pain; and genetic analysis can reveal known and new causes of neuropathic pain. Alongside existing patient- and parent-reported outcome measures, somatosensory system research methodologies and validation of mechanism-based standardised end-points may inform individualised therapy and stratification for clinical trials that will improve evidence-based management of neuropathic pain in children.

Abstract
The prevalence of cancer-related pain is 64% among patients with metastatic, advanced, or terminal cancer, 59% among patients undergoing anticancer treatment, and 33% among patients who completed curative treatment. According to the World Health Organization cancer pain relief guidelines, opioid analgesics are the mainstay analgesic therapy in addition to conventional first-step analgesics, such as non-steroidal anti-inflammatory drugs and acetaminophen. The indications for strong opioids have recently been expanded to include mild-to-moderate pain in addition to moderate-to-severe pain. The U.S. Centers for Disease Control and Prevention guidelines emphasize that realistic expectations should be weighed against potential serious harm from opioids, rather than relying on the unrealized long-term benefits of these drugs. Therefore, treatment strategies for both cancer-related chronic or acute pain have been unfortunately deviated from opioid analgesics. The barriers hindering adequate cancer-related pain management with opioid analgesics are related to the inadequate knowledge of opioid analgesics (e.g., effective dose, adverse effects, and likelihood of addiction or tolerance). To achieve adequate opioid availability, these barriers should be overcome in a clinically suitable manner. Genetic assessments could play an important role in overcoming challenges in opioid management. To balance the improvement in opioid availability and the prevention of opioid misuse and addiction, the following two considerations concerning opioids and genetic polymorphisms warrant attention: (A) pain severity, opioid sensitivity, and opioid tolerance; and (B) vulnerability to opioid dependence and addiction.

Abstract
This protocol will guide a review of clinical trials that evaluate the efficacy and safety of nonopioid analgesic drug combinations for the management of cancer-related pain. Introduction: Pain related to cancer, and its treatment, is common, may severely impair quality of life, and imposes a burden on patients, their families and caregivers, and society. Cancer-related pain is often challenging to manage, with limitations of analgesic drugs including incomplete efficacy and dose-related adverse effects. Objectives: Given problems with, and limitations of, opioid use for cancer-related pain, the identification of nonopioid treatment strategies that could improve cancer pain care is an attractive concept. The hypothesis that combinations of mechanistically distinct analgesic drugs could provide superior analgesia and/or fewer adverse effects has been tested in several pain conditions, including in cancer-related pain. Here, we propose to review trials of nonopioid analgesic combinations for cancer-related pain. Methods: Using a predefined literature search strategy, trials—comparing the combination of 2 or more nonopioid analgesics with at least one of the combination's individual components—will be searched on the PubMed and EMBASE databases from their inception until the date the searches are run. Outcomes will include pain intensity or relief, adverse effects, and concomitant opioid consumption. Results/Conclusions: This review is expected to synthesize available evidence describing the efficacy and safety of nonopioid analgesic combinations for cancer-related pain. Furthermore, a review of this literature will serve to identify future research goals that would advance our knowledge in this area.

Abstract
OBJECTIVES Somatosensory amplification (SA) has been described as an important feature of somatoform disorders, and an "amplifying somatic style" has been reported as a negative connotation of body perception. As widespread pain (WSP) in fibromyalgia (FM) is due to a central sensitization (CS) rather than organic alterations, there has been discussion as to whether FM is equivalent to or distinct from somatization disorder (SD). Assuming SD and FM are two distinct entities, an increase in somatic amplification should be expected only in subjects who have SD, regardless of the type of pain they experience. Purpose of the study was to explore the magnitude of SA in FM, and whether this depends on the association with SD. METHODS FM (n=159) other forms of chronic pain (OCP, n=582), psychiatric (Psy, n=53) and healthy (H, n=55) subjects were investigated using the Somatosensory Amplification Scale (SSAS), Illness Behavior Questionnaire, (IBQ), Italian Pain Questionnaire (IPQ), and Cold Pressor Test (CPT) in a retrospective observational study. RESULTS FM subjects displayed higher SSAS scores than the other groups. High SSAS score was associated with FM (OR=8.39; 95%CI: 5.43-12.46) but not OCP. Although FM has the highest prevalence of SD (x2=14.07; p=.007), high SSAS scores were associated with SD in OCP but not in FM. CONCLUSIONS Unlike in OCP, in FM high SSAS scores were independent of the presence of SD. From a biopsychosocial perspective, SSAS may be a factor associated with the onset of FM.

Abstract
It is estimated that one-third of oncologic patients in the USA do not receive analgesia proportional to or adequate for the intensity of their pain. A mechanism-based approach to oncologic pain therapy is critical to ensure that analgesia regimens are individualized and effective. Since the mechanisms that lead to cancer pain are complex, healthcare providers must be willing to elicit and recognize the symptoms of each individual patient since these factors influence both the experience of pain and response to treatment. This process is centered on the use of detailed history in order to understand symptom expression in the context of primary tumor diagnosis and progression, history of cancer pain, psychological distress, sleep disturbances, cognitive function, and addictive behavior. Incorporating all of these factors into the assessment of a patient's pain condition can facilitate management decisions and help predict patient response to treatment.

Abstract
Pain is one of the main problems for modern society and medicine, being the most common symptom described by almost all patients. When pain becomes chronic, the life of the patients is dramatically affected, being associated with significant emotional distress and/or functional disability. A complex biopsychosocial evaluation is necessary to better understand chronic pain, where good results can be obtained through interconnected biological, psychological, and social factors. The aim of this study was to find the most relevant articles existent in the PubMed database, one of the most comprehensive databases for medical literature, comprising dietary patterns to alleviate chronic pain. Through a combined search using the keywords "chronic pain" and "diet" limited to the last 10 years we obtained 272 results containing the types of diets used for chronic pain published in the PubMed database. Besides classical and alternative methods of treatment described in literature, it was observed that different diets are also a valid solution, due to many components with antioxidant and anti-inflammatory qualities capable to influence chronic pain and to improve the quality of life. Thirty-eight clinical studies and randomized controlled trials are analyzed, in an attempt to characterize present-day dietary patterns and interventions to alleviate chronic pain.

[PMID: 32656459 PMCID: PMC7318717 DOI: 10.1097/pr9.0000000000000825] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 04/17/2020] [Accepted: 04/25/2020] [Indexed: 11/26/2022] Open
Abstract
Introduction The purpose of the present ecological implementation field study is to evaluate the new classification of chronic pain as implemented in the 11th revision of the International Classification of Diseases (ICD-11) with regard to clinical utility and interrater reliability. To evaluate the classification in a variety of settings, the study will be implemented in different low-, middle-, and high-income countries. Methods The study will be conducted in 2 phases. Participating pain clinics of the first phase are located in India, Cuba, and New Zealand. Two or more clinicians per study center will use the ICD-11 classification of chronic pain to diagnose 75 to 100 consecutive new chronic pain patients per center. A structured classification algorithm will guide the diagnostic process. Interrater reliability will be analyzed for the first 20 consecutive new patients per center. Before the coding, a training workshop will introduce the clinicians to the new classification. The main outcome parameter of the ecological implementation field study is clinical utility. More specifically, this entails clinical utility ratings, interrater reliability, as well as the exhaustiveness of the classification and the mutual exclusiveness of the new chronic pain categories. Differences between countries with different cultural backgrounds and income levels will be analyzed. Perspective The ecological implementation field study presented here will be implemented in several countries with different income levels. This increases the generalizability of the results and allows initial insight into the global applicability of the new chronic pain classification. A positive evaluation can facilitate the implementation of the classification.

Abstract
INTRODUCTION Breakthrough pain is common in children and adults with cancer and other conditions, including those approaching end-of-life, although it is often poorly managed, possibly partly due to a lack of validated assessment tools. This review aims to (1) identify all available instruments measuring breakthrough pain in infants, children, adolescents or adults and (2) critically appraise, compare and summarise the quality of the psychometric properties of the identified instruments using COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) criteria. METHODS AND ANALYSIS Two searches will be carried out between October 2019 and January 2020, one for each aim of the review. The Cochrane Library, International Prospective Register of Systematic Reviews, Embase, Cumulative Index of Nursing and Allied Health Literature, Medical Literature Analysis and Retrieval System Online (MEDLINE), PsycINFO, Web of Science Core Collection, Google Scholar, the ProQuest Dissertations & Theses Database, Evidence Search and OpenGrey databases will be searched from database inception until the date the search is conducted. Reference lists of eligible articles will be screened and authors in the field contacted. For search 1, articles will be screened by two reviewers by abstract, and full-text where necessary, to identify if a breakthrough pain assessment was used. Search 2 will then be conducted to identify studies evaluating measurement properties of these assessments. Two reviewers will screen articles from search 2 by title and abstract. All potentially relevant studies will be screened by full text by both reviewers. For search 2, data will be extracted in parallel with the quality assessment process, as recommended by COSMIN. Two reviewers will assess methodological quality using the COSMIN Risk of Bias checklist and the COSMIN updated criteria for good measurement properties. Findings will be summarised and, if possible, data will be pooled using meta-analysis. The quality of the evidence will be graded and summarised using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) guidelines. ETHICS AND DISSEMINATION Results of this review will be submitted for publication in a peer review journal and presented at conferences. PROSPERO REGISTRATION NUMBER CRD42019155583.

Abstract
Bone cancer pain (BCP) is one of the most common types of chronic cancer pain and its pathogenesis has not been fully understood. Long non-coding RNAs (lncRNAs) are new promising targets in the field of pain research, however, their involvements in BCP have not been reported. In the present study, we established the BCP model by implantation of Walker 256 carcinoma cells into rats' tibial medullary cavity and performed transcriptome sequencing of the ipsilateral lumbar spinal cord to explore changes in expression profiles of lncRNA and mRNA. We identified 1220 differently expressed mRNAs (DEmRNAs) (1171 up-regulated and 49 down-regulated) and 323 differently expressed lncRNAs (DElncRNAs) (246 up-regulated and 77 down-regulated) in BCP model, among which 10 DEmRNAs (5 up-regulated and 5 down-regulated) and 10 DElncRNAs (5 up-regulated and 5 down-regulated) were validated the expression by RT-qPCR. Then, we performed Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis on the expression of DEmRNAs and DElncRNAs, showing that they were mainly enriched in inflammatory and immunologic processes/pathways. Finally, we constructed a co-expression network and a ceRNA network of DEmRNAs and DElncRNAs to exhibit a potential regulatory mechanism of DElncRNAs, directly regulating protein coding gene expression in cis or in trans and indirectly regulating protein coding gene expression by sponging miRNA. In conclusion, our study provided a landscape of dysregulated lncRNA and mRNA in spinal cord of bone cancer pain and detected novel potential targets for treatment in the future.

Abstract
INTRODUCTION: Self-efficacy is defined as the strength of a person’s convictions in being able to perform a given activity and obtain the expected result. It may act as a potent mediator between chronic musculoskeletal pain and how older adults cope with their disabilities. OBJECTIVE: To evaluate the determinants of self-efficacy beliefs and fear of physical exercise in community-dwelling older adults with chronic musculoskeletal pain. METHODS: This cross-sectional study recruited older adults with chronic musculoskeletal pain. Only individuals living in an urban area in southern Brazil and who reported pain for more than 3 months were included. A convenience sample was selected in a nonprobabilistic fashion. The study variables consisted of sociodemographic data; pain based on the Brief Pain Inventory and the Leeds Assessment of Neuropathic Symptoms and Signs for Patients with Chronic Pain; and self-efficacy based on the Chronic Pain Self-Efficacy Scale. Also, simple questions were created for physical exercise beliefs. For statistical analysis, absolute and relative frequency, χ2 test, and Mann-Whitney U test were used as appropriate. RESULTS: The sample consisted of 193 older adults, mostly women with low level of education. Self-efficacy was best rated by older adults living alone and by those who were classified as exclusively nociceptive pain. CONCLUSION: Despite having chronic pain, older adults with higher self-efficacy feel confident in performing their tasks and have greater ability to cope with changes related to aging and to engage in self-care.

Abstract
Objective The purpose of this qualitative study was to describe the experiences of pain acceptance in Chinese cancer patients with chronic pain. Methods Twelve hospitalized cancer patients with chronic pain participated in this qualitative descriptive study from August to November 2017. In-person semi-structured interviews were conducted, recorded, transcribed, and analyzed using Colaizzi's seven-step method. Results The following four main themes and 15 subthemes emerged. Theme 1 (adaptation): pain is overwhelming and pain relief is a top priority, avoidance of pain-inducing factors, and resignation; theme 2 (emotional reactions to pain): feeling misunderstood, hopelessness, frustration, irritability, and concern for loved ones; theme 3 (functional limitations): daily life activities, social communication, and work; theme 4 (coping strategies): pharmacological therapies, behavioral strategies, social support strategies, and spiritual strategies. Conclusions This study provides a description of cancer patients' experiences related to the need for pain acceptance. These findings provide insight into the essential role of pain acceptance and underline the need to apply acceptance-based cognitive behavioral interventions as adjunctive non-pharmacological alternatives for chronic cancer pain.

Best-Evidence Rehabilitation for Chronic Pain Part 2: Pain during and after Cancer Treatment. J Clin Med 2019; 8:jcm8070979.

Abstract
Pain during, and especially after, cancer remains underestimated and undertreated. Moreover, both patients and health care providers are not aware of potential benefits of rehabilitation strategies for the management of pain during and following cancer treatment. In this paper, we firstly provided a state-of-the-art overview of the best evidence rehabilitation modalities for patients having (persistent) pain during and following cancer treatment, including educational interventions, specific exercise therapies, manual therapies, general exercise therapies and mind-body exercise therapies. Secondly, the findings were summarized from a clinical perspective and discussed from a scientific perspective. In conclusion, best evidence suggests that general exercise therapy has small pain-relieving effects. Supporting evidence for mind-body exercise therapy is available only in breast cancer patients. At this moment, there is a lack of high-quality evidence to support the use of specific exercises and manual therapy at the affected region for pain relief during and after cancer treatment. No clinically relevant results were found in favor of educational interventions restricted to a biomedical approach of pain. To increase available evidence these rehabilitation modalities should be applied according to, and within, a multidisciplinary biopsychosocial pain management approach. Larger, well-designed clinical trials tailored to the origin of pain and with proper evaluation of pain-related functioning and the patient’s pain experience are needed.

Abstract
PURPOSE A clinical care pathway for pain management in a palliative care unit was studied with outcomes related to patients, physicians, and health care service. Mandatory use of patient-reported outcome measures (PROMs) and physician-directed decision support (DS) were integrated parts of the pathway. METHODS Adult cancer patients with pain intensity (PI) ≥ 5 (NRS 0-10) at admission were eligible. The patients reported average and worst PI at admission, day four, and discharge. The physicians completed the DS at admission and day four. The DS presented potential needs for treatment changes based on pain severity and pathophysiology. The physicians reported treatment changes due to input from the DS system. The two primary outcomes were average and worst PI changes from admission to discharge. Hospital length of stay (LOS) was registered. RESULTS Of 52 included patients, 41 were discharged alive. For those, the mean average PI at admission and at discharge was 5.8 and 2.4, respectively, a reduction of 3.4 points (CI 95% 2.7-4.1). The corresponding worst pain intensities were 7.9 and 3.8, a reduction of 4.1 points (CI 95% 3.4-4.8). The physicians completed DS forms for all patients. Fifty-five percent (CI 95% 41-69) of the patients had pain intervention changes based on the DS. A significant reduction in LOS (4.4 days, CI 95% 0.5-8.3) was observed during the study period. CONCLUSIONS The interventions were implemented according to the intentions and PI was reduced as hypothesized. For evaluation of generalizability, the interventions should be studied in other settings and with a controlled design.

Abstract
OBJECTIVES To describe assessment and interdisciplinary management of pain in the cancer survivor over the continuum of cancer care. DATA SOURCES Review of the literature and treatment standards. CONCLUSION Pain remains a primary concern throughout the cancer trajectory across all age groups and diagnoses, emphasizing the need to integrate pain assessment and management across the continuum of cancer survivorship and across care settings. Types of pain, pain patterns, assessment of cancer pain in cancer survivors, current strategies and challenges for management, and effective communication and documentation of the process are described. Communication between and among health care clinicians in a way that effectively articulates the individual patient experience, including documentation in the electronic medical record, requires consistent workflows and terminology. The opioid crisis increases the urgency in effective strategies for interdisciplinary pain assessment and management. IMPLICATIONS FOR NURSING PRACTICE Oncology clinicians must be able to adequately assess pain, track pain over time, understand and implement a cadre of strategies to manage pain, and effectively pursue any suspicious pain patterns that may indicate recurrence or progression of cancer or other underlying etiologies. The oncology nurse is at the core of patient-clinician communication, critical to effectively describing pain as experienced by the individual patient and continues to play a key role in maintaining consistency of message that is necessary to manage pain over the continuum of cancer survivorship.

Abstract
Omega-3 polyunsaturated fatty acids (PUFAs) are considered immunonutrients and are commonly used in the nutritional therapy of cancer patients due to their ample biological effects. Omega-3 PUFAs play essential roles in cell signaling and in the cell structure and fluidity of membranes. They participate in the resolution of inflammation and have anti-inflammatory and antinociceptive effects. Additionally, they can act as agonists of G protein-coupled receptors, namely, GPR40/FFA1 and GPR120/FFA4. Cancer patients undergo complications, such as anorexia-cachexia syndrome, pain, depression, and paraneoplastic syndromes. Interestingly, the 2017 European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines for cancer patients only discuss the use of omega-3 PUFAs for cancer-cachexia treatment, leaving aside other cancer-related complications that could potentially be managed by omega-3 PUFA supplementation. This critical review aimed to discuss the effects and the possible underlying mechanisms of omega-3 PUFA supplementation in cancer-related complications. Data compilation in this critical review indicates that further investigation is still required to assess the factual benefits of omega-3 PUFA supplementation in cancer-associated illnesses. Nevertheless, preclinical evidence reveals that omega-3 PUFAs and their metabolites might modulate pivotal pathways underlying complications secondary to cancer, indicating that this is a promising field of knowledge to be explored.

Abstract
More than half of patients affected by cancer experience pain of moderate-to-severe intensity, often in multiple sites, and of different etiologies and underlying mechanisms. The heterogeneity of pain mechanisms is expressed with the fluctuating nature of cancer pain intensity and clinical characteristics. Traditional ways of classifying pain in the cancer population include distinguishing pain etiology, clinical characteristics related to pain and the patient, pathophysiology, and the use of already validated classification systems. Concepts like breakthrough, nociceptive, neuropathic, and mixed pain are very important in the assessment of pain in this population of patients. When dealing with patients affected by cancer pain it is also very important to be familiar to the characteristics of specific pain syndromes that are usually encountered. In this article we review methods presently applied for classifying cancer pain highlighting the importance of an accurate clinical evaluation in providing adequate analgesia to patients.

Abstract
BACKGROUND AND OBJECTIVE Pain is a common symptom in patients who survive cancer and in those who live with progressive advanced disease. Evidence from meta-analyses suggests that pain remains poorly controlled for a large proportion of patients; barriers to good management include poor assessment of pain, inadequate support for patient self-management and late or inadequate access to strong opioid analgesia in those with advanced disease. METHODS The European Pain Federation (EFIC) established a Task Force in 2017 which convened a European group of experts, drawn from a diverse range of relevant clinical disciplines, to prepare a position paper on appropriate standards for the management of cancer-related pain. The expert panel reviewed the available literature and made recommendations using the GRADE system to combine quality of evidence with strength of recommendation. The panel took into account the desirable and undesirable effects of the management recommendation, including the cost and inconvenience of each when deciding the recommendation. RESULTS AND CONCLUSIONS The 10 standards presented are aimed to improve cancer pain management and reduce variation in practice across Europe. The Task Force believes that adoption of these standards by all 37 countries will promote the quality of care of patients with cancer-related pain and reduce unnecessary suffering. SIGNIFICANCE Pain affects up to 40% of cancer survivors and affects at least 66% of patients with advanced progressive disease, many of whom experience poor pain control. These 10 standards are aimed to improve cancer pain management, promote the quality of care of patients and reduce variation across Europe.

Abstract
The upcoming 11th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD) of the World Health Organization (WHO) offers a unique opportunity to improve the representation of painful disorders. For this purpose, the International Association for the Study of Pain (IASP) has convened an interdisciplinary task force of pain specialists. Here, we present the case for a reclassification of nervous system lesions or diseases associated with persistent or recurrent pain for ≥3 months. The new classification lists the most common conditions of peripheral neuropathic pain: trigeminal neuralgia, peripheral nerve injury, painful polyneuropathy, postherpetic neuralgia, and painful radiculopathy. Conditions of central neuropathic pain include pain caused by spinal cord or brain injury, poststroke pain, and pain associated with multiple sclerosis. Diseases not explicitly mentioned in the classification are captured in residual categories of ICD-11. Conditions of chronic neuropathic pain are either insufficiently defined or missing in the current version of the ICD, despite their prevalence and clinical importance. We provide the short definitions of diagnostic entities for which we submitted more detailed content models to the WHO. Definitions and content models were established in collaboration with the Classification Committee of the IASP's Neuropathic Pain Special Interest Group (NeuPSIG). Up to 10% of the general population experience neuropathic pain. The majority of these patients do not receive satisfactory relief with existing treatments. A precise classification of chronic neuropathic pain in ICD-11 is necessary to document this public health need and the therapeutic challenges related to chronic neuropathic pain.
