Efficacy of azasetron on postoperative chronic pain after pulmonary surgery: a randomized triple-blind controlled trial

BackgroundInhibition of 5-HT3 (5-Hydroxyl Tryptamine) receptors is known to enhance morphine analgesia in animal models. We tested the efficacy of azasetron, a 5-HT3 receptor antagonist, on postoperative chronic pain after pulmonary surgery in a randomized triple-blind controlled study.MethodsA total of 250 patients who were scheduled to receive pulmonary surgery were randomized to patient-controlled analgesia (PCA) using 200 µg sufentanil with normal saline or 200 µg sufentanil with 20 mg azasetron. The numerical rating scale of pain (NRS) was recorded at baseline, postoperative day (POD) 1, 2, 3, 90, and 180. Negative binomial regression was used to identify associated factors for postoperative NRS six months after surgery.ResultsThe results showed that azasetron did not affect the primary outcomes: the incidence of postoperative chronic pain on POD90 and 180. However, azasetron decreased postoperative NRS at rest and activity on POD1, 2, and 3. Furthermore, azasetron decreased postoperative nausea and vomiting on POD1 and 2. Univariate and multivariate negative binomial regression analysis identified preoperative pain, smoking, drinking and open surgery are risk factors of chronic pain six months after surgery.ConclusionsAzasetron did not affect the incidence of chronic pain after pulmonary surgery. The presence of preoperative pain, smoking, drinking, and open surgery were found to be associated with chronic pain six months after surgery.Clinical trial registrationThe trial was registered prior to patient enrollment at the Chinese Clinical Trial Registry (ChiCTR2200060139), 20/05/2022; the site url is https://www.chictr.org.cn/.

How is age at menopause and reproductive lifespan associated with chronic pain outcomes in postmenopausal women?

Female sex is a prominent risk factor for chronic pain, although the underlying mechanisms are not fully understood. This cross-sectional study aimed to investigate the relationship between age at menopause, reproductive lifespan, and chronic pain in a sample of postmenopausal women aged 40 to 93 years. Data were collected from the Tromsø study conducted in Norway between 2015 and 2016 (Tromsø7). Chronic pain was assessed using a single question, which formed a sample size of 5741 participants. Chronic widespread pain was evaluated using the more comprehensive Graphical Index of Pain, resulting in a sample size of 5920 women. Premenopausal women and those who experienced menstrual cessation due to chemotherapy/radiation or hormonal intrauterine devices were excluded from the analysis. Adjusted relative risk ratios with 95% confidence intervals were calculated to determine associations. The results showed that early menopause was associated with a 1% increase in the prevalence of chronic pain for each year of earlier onset at menopause (0.992, CI 95% 0.985-0.998). This association was also observed in women who experienced natural menopause only. However, the association between menopause and chronic widespread pain did not reach statistical significance in the fully adjusted analysis (0.996, CI 95% 0.975-1.017). There were no significant associations found between reproductive lifespan and either outcome. In conclusion, the findings suggest that early menopause in postmenopausal women is linked to a higher prevalence of chronic pain. However, reproductive lifespan does not appear to have a significant impact on chronic pain or chronic widespread pain.

Chronic Postsurgical Pain Following Lung Transplantation: Characteristics, Risk Factors, Treatment, and Prevention: A Narrative Review.

Chronic pain after lung transplantation (LTx) can substantially reduce quality of life (QoL), yet current consensus guidelines say little about how to prevent or manage it. Research on pain after LTx has tended to focus on acute rather than chronic pain, and it has not extensively examined the factors associated with onset or resolution of chronic pain, which differ from factors influencing chronic pain after general thoracic surgery. This narrative review explores what is known about the epidemiology and risk factors of chronic pain after LTx, as well as effective ways to treat or prevent it. The review identifies key questions and issues that should be the focus of future research.

Blood cadmium level as a risk factor for chronic pain: NHANES database 1999-2004.

The escalating prevalence of chronic pain poses a substantial socio-economic burden. Chronic pain primarily stems from musculoskeletal and nervous system impairments. Given cadmium's known toxicity to these systems, our study sought to investigate the correlation between blood cadmium levels and chronic pain. The cross-sectional study was conducted from the National Health and Nutrition Examination Survey (NHANES, 1999-2004), and comprised US adults who participated in a chronic pain interview. We employed logistic regression models and smooth curve fitting to elucidate the relationship between blood cadmium levels and chronic pain. Our findings revealed a linear association between blood cadmium levels and chronic pain. Compared to the lower blood cadmium tertile 1 (<0.3 ug/dL), the adjusted odds ratios (ORs) for tertile 2 (0.3-0.4 ug/dL), and tertile 3 (≥0.5 ug/dL), were 1.11 (0.96-1.29) and 1.2 (1.03-1.39), respectively. Sensitivity analyses corroborated these results. Elevated levels of blood cadmium are associated with a heightened risk of chronic pain among adults in the United States. Mitigating cadmium exposure could potentially decrease the risk of chronic pain, thereby enhancing strategies for chronic pain prevention and management.

The sex-dependent impact of adipose tissue and inflammation on chronic pain – A cross-sectional study from the all of us research program

Emerging evidence suggests an association between chronic pain and elevated body fat. We sought to determine if individuals with higher body fat, measured by hip circumference (HC) and waist circumference (WC), are at risk for chronic pain when they demonstrate higher expression of inflammatory markers. We investigated the incidence and severity of pain in patients with varying WC/HC and inflammatory markers (C-Reactive Protein, IL-6, leptin) using the NIH-sponsored All of Us Database. For each inflammatory marker and sex, participants were divided into four groups based on combinations of normal/high marker levels and small/large WC/HC. We used statistical analysis to compare WC/HC and pain severity (mean NRS pain score) between groups of the same sex. In females, but not males, combinations of elevated CRP with large WC/HC exerted additive effects on the incidence of chronic pain (p < 0.01) and severe pain (p < 0.001), as well as on the severity of pain evaluated by the mean NRS pain score (p < 0.01). This relationship held true for females with high IL-6 or leptin and large WC or HC (p < 0.001 for chronic pain and severe pain incidence, and p < 0.05 for pain severity). Neither IL-6 nor leptin showed any significant impact on pain in males. Obesity status and CRP exert additive prognostic effects for chronic pain in females, but not in males. The concomitant evaluation of other inflammatory factors, such as IL-6 or leptin in females, may further augment the prediction of chronic pain. PerspectiveThis article investigates the relationship between chronic pain, obesity, and inflammatory markers. It could help elucidating sex difference in pain mechanisms, as well as the risk factors for chronic pain, potentially improving patient diagnosis, follow-up and treatment.

Adverse Childhood Experiences and Chronic Low Back Pain in Adulthood: The Role of Emotion Regulation

Chronic low back pain (cLBP) is characterized by biopsychosocial determinants that collectively result in a substantial burden at the individual, community, and health care system levels. A growing body of literature suggests that childhood adversity is longitudinally associated with the development and maintenance of various chronic pain conditions in adulthood. Little research has investigated the psychological processes that might underlie the association between adverse childhood experiences (ACEs) and cLBP. Emotion regulation comprises a substantive part of the subjective experience of pain and may be a potential mechanism through which ACEs contribute to cLBP etiology and maintenance. Thus, the current study examined the extent to which emotion dysregulation mediated the relationship between ACEs and pain severity (pain at rest and movement-evoked pain) in adults with cLBP. Participants included 183 adults (53.0% female, 62.5% non-Hispanic Black) between the ages of 18 and 85 with cLBP. Participants self-reported on ACEs, pain, difficulties in emotion regulation (DER), depression, and completed brief physical function tasks. In data analytic models, sociodemographic variables were included as covariates. Analyses revealed that emotion regulation mediated the relationship between ACEs and cLBP severity at rest (indirect effect = .15 [95% CI {.06–.25}]) and with movement (indirect effect = 1.50 [95% CI {.69–2.57}]). Findings suggest ACEs are linked to cLBP severity in adulthood through DER. This aligns with research demonstrating that childhood maltreatment can lead to DER, which perpetuate over the lifespan to impact adult health outcomes. PerspectiveThis study presents emotion dysregulation as a psychological pathway through which childhood adversity may contribute to cLBP in adulthood. This work may bolster our understanding of social experiences as risk factors for chronic pain, while identifying targets for clinical intervention. Trial RegistrationThis study utilized baseline data collected as part of a parent trial titled “Examining Racial and SocioEconomic Disparities in Chronic Low Back Pain” (ClinicalTrials.gov ID: NCT03338192).

Higher rate of chronic pain in young men after open mesh vs nonmesh repair of elective primary unilateral indirect inguinal hernia: A nationwide questionnaire study

PurposeYoung age is a risk factor for chronic pain after inguinal hernia repair, but the role of the mesh in young patients is uncertain. The aim of this study was to assess chronic pain after open mesh versus non-mesh repair of indirect inguinal hernia in young men. Materials and methodsValidated questionnaires were sent to men aged 18–29 years at the time of an elective primary unilateral open repair of an indirect inguinal hernia between 1998 and 2015. Patients were identified in the Danish Hernia Database. Non-mesh repairs were matched 1:3 with mesh repairs (Lichtenstein) on age and follow-up time. The primary outcome was the proportion of patients with chronic pain evaluated with the Activity assessment scale. Secondary outcomes included other pain measures and sexual impairment. ResultsIn total, 661 patients were included in this study (77% mesh and 23% non-mesh) with a median follow-up of 14.8 years (range 2.3–20.0) in the mesh group and 15.9 years (range 3.6–20.0) in the non-mesh group. For the primary outcome, 12% of patients in the mesh group compared with 6% in the non-mesh group had chronic pain (p=0.03). Patients in the mesh group had higher odds of chronic pain in adjusted analysis (OR=2.30 [95% confidence interval=1.11–4.77]). More patients in the mesh group had pain during sexual activity (p=0.01), but there were no differences for most of the remaining secondary outcomes. ConclusionYoung men had a higher rate of chronic pain after open mesh compared with non-mesh repair for indirect inguinal hernia, but results should be interpreted with caution.

Different pain phenotypes are associated with anti-Caspr2 autoantibodies

Autoantibodies against contactin-associated protein 2 (Caspr2) not only induce limbic autoimmune encephalitis but are also associated with pain conditions. Here, we analyzed clinical data on pain in a large cohort of patients included into the German Network for Research in Autoimmune Encephalitis. Out of 102 patients in our cohort, pain was a frequent symptom (36% of all patients), often severe (63.6% of the patients with pain) and/or even the major symptom (55.6% of the patients with pain). Pain phenotypes differed between patients. Cluster analysis revealed two major phenotypes including mostly distal-symmetric burning pain and widespread pain with myalgia and cramps. Almost all patients had IgG4 autoantibodies and some additional IgG1, 2, and/or 3 autoantibodies, but IgG subclasses, titers, and presence or absence of intrathecal synthesis were not associated with the occurrence of pain. However, certain pre-existing risk factors for chronic pain like diabetes mellitus, peripheral neuropathy, or preexisting chronic back pain tended to occur more frequently in patients with anti-Caspr2 autoantibodies and pain. Our data show that pain is a relevant symptom in patients with anti-Caspr2 autoantibodies and support the idea of decreased algesic thresholds leading to pain. Testing for anti-Caspr2 autoantibodies needs to be considered in patients with various pain phenotypes.

Construction and validation of chronic pain prediction model after total knee arthroplasty.

To explore the risk factors of chronic pain after total knee arthroplasty (TKA) and to establish and verify a prediction model. As a retrospective observational study, medical records of 239 patients who underwent TKA in Affiliated Hospital of Jiangnan University from January 2020 to December 2022 were reviewed. Fifty four patients suffered from chronic pain after TKA surgery. Univariate and multivariate logistic regression were used to analyze factors associated with the occurrence of chronic pain after TKA. A nomogram prediction model was established based on the identified independent risk factors, and its predictive effectiveness was evaluated. Gender, postoperative 24-hourss numerical rating scale (NRS) and postoperative three months Hospital for Special Surgery Knee-Rating (HSS) scores were independent risk factors for chronic pain after TKA (p<0.05). The area of the receiver operating characteristic (ROC) of the nomogram model based on these factors was 0.904 (95% confidence interval [CI): 0.861-0.947), which indicates a good predictive value for the postoperative chronic pain. When the optimal cut off value was selected, the sensitivity and specificity of the model were 92.6% and 74.1%, respectively, indicating that the predictive model is effective. Gender, postoperative 24-hours NRS and postoperative three months HSS score are independent risk factors for chronic pain after TKA. The nomogram prediction model based on these factors is effective and can provide auxiliary reference for patients with chronic pain after TKA.

Nociceptive Processing of Elite Athletes Varies between Sport-Specific Loads: An EEG-Based Study Approach.

For the downstream nociceptive processing of elite athletes, recent studies indicate that athletes probably tolerate more pain as compared with a normally active population. Phenotyping the nociceptive processing of athletes in different types of endurance sports can provide insight into training-specific effects, which may help in understanding the long-term effects of specific exercise. Twenty-six elite endurance athletes from the disciplines of rowing, triathlon, and running and 26 age- and sex-matched, recreationally active control subjects who participated in the subjective pain perception and processing of standardized noxious stimuli were investigated by EEG. This included standardized heat pain thresholds (HPT) and contact heat-evoked potentials from heat stimulation, measured with EEG as well as pinprick-evoked potentials from mechanical stimulation. After noxious stimulation, athletes showed a higher activation of the event-related spectral perturbation (ERSP) patterns in the N2P2 EEG response at the Cz Electrode compared with the controls. After noxious contact heat stimulation, triathletes had a higher ERSP activation compared with the controls, whereas the rowers had a higher ERSP activation after noxious mechanical stimulation. Also, HPT in triathletes were increased despite their increased central activation after thermal stimulation. We found a correlation between increased HPT and training hours and years, although athletes did not differ within these variables. Although we were able to identify differences between athletes of different endurance sports, the reasons and implications of these differences remain unclear. The study of sport-specific somatosensory profiles may help to understand the mechanisms of exercise-related long-term effects on pain processing and perception. Furthermore, sport-specific somatosensory effects may support the personalization of exercise interventions and identify risk factors for chronic pain in elite athletes.

Immigration background as a risk factor of chronic pain and high-impact chronic pain in children and adolescents living in Spain: differences as a function of age.

The number of people immigrating from one country to another is increasing worldwide. Research has shown that immigration background is associated with chronic pain (CP) and pain disability in adults. However, research in this issue in children and adolescents has yielded inconsistent results. The aims of this study were to examine (1) the association between immigration background, CP, high-impact chronic pain (HICP) in a community sample of children and adolescents; and (2) the extent these associations differed as a function of sex and age. Participants of this cross-sectional study were 1115 school children and adolescents (mean age = 11.67; 56% girls). Participants were asked to provide sociodemographic information and respond to a survey including measures of pain (location, extension, frequency, intensity, and interference). Results showed that having an immigration background was associated with a greater prevalence of CP (OR = 1.91, p <.001) and HICP (OR = 2.55, p <. 01). Furthermore, the association between immigration background and CP was higher in children (OR = 6.92, p <.001) and younger adolescents (OR = 1.66, p <.05) than in older adolescents. Children and adolescents with an immigration background are at higher risk for having CP -especially younger children- and HICP. More resources should be allocated in the prevention of CP and HICP in children and adolescents with an immigration background.

The Risk Factors of Chronic Pain in Victims of Violence: A Scoping Review.

Violent situations are unfortunately very frequent in women and children all over the world. These experiences have long-term consequences for adult physical and psychological health. One of the most reported is chronic pain, defined in various sub-diagnoses and present in all types of violence. Unfortunately, the etiology of this condition is not clear and neither are the predisposing factors. The aim of this scoping review is to examine the literature trends about the probable risk factors of chronic pain in violence victims. Considering a bio-psycho-social model, it is possible to hypothesize the presence of all these aspects. The results will be discussed in the present article.

Chronic thoracic pain after cardiac surgery: role of inflammation and biomechanical sternal stability.

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. 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. 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. 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.

Assessing the feasibility of a clinical trial to evaluate an advanced practice physiotherapy model of care in chronic pain management: a feasibility study

BackgroundChronic pain management is challenging for health systems worldwide. Clinical practice guidelines recommend interprofessional chronic pain management, but chronic pain clinics often have lengthy wait-lists. Advanced practice physiotherapists (APP) in orthopedic clinics and emergency departments have provided effective care and reduced wait times. The purpose of this study is to determine the feasibility of a clinical trial to evaluate the effects of integrating an APP into a chronic pain clinic setting. The primary objectives are as follows: (1) determine the feasibility of implementing trial methods by evaluating participant recruitment rates, retention, and assessment completion; (2) determine the feasibility of implementing the APP model of care by monitoring care provided and treatment fidelity; and (3) assess contextual factors that may influence implementation of the APP model of care by exploring the perspectives of patient participants and healthcare providers related to the model of care.MethodsThis will be a single-arm feasibility study with embedded qualitative interviews to assess contextual factors influencing implementation by exploring participant and provider perspectives. Approximately 40 adults with chronic musculoskeletal pain referred for care at an interprofessional chronic pain clinic will be invited to participate in the feasibility study. Approximately 10–12 patient participants and 5–10 health professionals from the interprofessional team will be interviewed using an interpretive description approach. The APP model of care will involve participants seeing a physiotherapist as the first point of contact within the interprofessional team. The APP will complete an initial assessment and make care recommendations. Outcome measures planned for the full trial will be reported descriptively, including pain severity, pain interference, health-related quality of life, psychosocial risk factors for chronic pain, treatment satisfaction, perceived change, healthcare utilization, and healthcare costs over one year.DiscussionThis study will inform plans to implement a full-scale study to evaluate the impact of an APP model of care in an interprofessional chronic pain management program. The results of the full study are intended to inform stakeholders considering this model to improve patient-centered and health system outcomes in interprofessional pain management program settings.Trial registrationClinicalTrials.gov, NCT05336903 (Registered April 5, 2022).

COVID-19 symptom load as a risk factor for chronic pain: A national cross-sectional study.

Emerging evidence suggests that a COVID-19 infection with a high initial severity may be associated with development of long-COVID conditions such as chronic pain. At the population level, it is unknown if severity of a COVID-19 infection might be a new risk factor for chronic pain above and beyond the traditional slate of pre-established risk factors. The purpose of this study is to examine whether COVID-19 severity of infection may be a new risk factor for chronic pain. Using data from the 2021 National Health Interview Survey (n = 15,335), this study examined the adjusted odds of experiencing high frequency levels of pain in the past 3 months for those who reported no/mild symptoms from a COVID-19 infection, and those reporting moderate/severe symptoms from COVID-19, compared to those never infected. A 1:1:1 propensity score matched analysis was also performed to examine the odds of pain. Prevalence of pain was higher in the moderate/severe symptom group compared to the no infection group (25.48% vs 19.44%, p <0.001). Both the adjusted model (odds ratio [OR] = 1.28, 95% confidence interval [CI] = 1.09, 1.51) and matched model (OR = 1.45, CI = 1.14, 1.83) revealed higher odds of pain for those with moderate/high COVID-19 symptoms compared to no infection. A moderate/highly symptomatic COVID-19 infection may be a new risk factor for chronic pain. As the absolute number of severe COVID-19 infections continues to rise, overall prevalence of chronic pain may also increase. While knowledge continues to unfold on long-haul symptoms, prevention of severe infections remains essential.

Microglia sustain anterior cingulate cortex neuronal hyperactivity in nicotine-induced pain

BackgroundLong-term smoking is a risk factor for chronic pain, and chronic nicotine exposure induces pain-like effects in rodents. The anterior cingulate cortex (ACC) has been demonstrated to be associated with pain and substance abuse. This study aims to investigate whether ACC microglia are altered in response to chronic nicotine exposure and their interaction with ACC neurons and subsequent nicotine-induced allodynia in mice.MethodsWe utilized a mouse model that was fed nicotine water for 28 days. Brain slices of the ACC were collected for morphological analysis to evaluate the impacts of chronic nicotine on microglia. In vivo calcium imaging and whole-cell patch clamp were used to record the excitability of ACC glutamatergic neurons.ResultsCompared to the vehicle control, the branch endpoints and the length of ACC microglial processes decreased in nicotine-treated mice, coinciding with the hyperactivity of glutamatergic neurons in the ACC. Inhibition of ACC glutamatergic neurons alleviated nicotine-induced allodynia and reduced microglial activation. On the other hand, reactive microglia sustain ACC neuronal excitability in response to chronic nicotine, and pharmacological inhibition of microglia by minocycline or liposome-clodronate reduces nicotine-induced allodynia. The neuron-microglia interaction in chronic nicotine-induced allodynia is mediated by increased expression of neuronal CX3CL1, which activates microglia by acting on CX3CR1 receptors on microglial cells.ConclusionTogether, these findings underlie a critical role of ACC microglia in the maintenance of ACC neuronal hyperactivity and resulting nociceptive hypersensitivity in chronic nicotine-treated mice.

Rs11726196 Single-Nucleotide Polymorphism of the Transient Receptor Potential Canonical 3 (TRPC3) Gene Is Associated with Chronic Pain.

Chronic pain is reportedly associated with the transient receptor potential canonical 3 (TRPC3) gene. The present study examined the genetic associations between the single-nucleotide polymorphisms (SNPs) of the TRPC3 gene and chronic pain. The genomic samples from 194 patients underwent linkage disequilibrium (LD) analyses of 29 SNPs within and around the vicinity of the TRPC3 gene. We examined the associations between the SNPs and the susceptibility to chronic pain by comparing the genotype distribution of 194 patients with 282 control subjects. All SNP genotype data were extracted from our previous whole-genome genotyping results. Twenty-nine SNPs were extracted, and a total of four LD blocks with 15 tag SNPs were observed within and around the TRPC3 gene. We further analyzed the associations between these tag SNPs and chronic pain. The rs11726196 SNP genotype distribution of patients was significantly different from the control subjects even after multiple-testing correction with the number of SNPs. The TT + TG genotype of rs11726196 is often carried by chronic pain patients, suggesting a causal role for the T allele. These results contribute to our understanding of the genetic risk factors for chronic pain.

Moral injury and chronic pain among military veterans in an integrated behavioral health clinic.

Military service may place veterans at increased risk for perpetrating, witnessing, or failing to prevent events that violate deeply held moral values. In some cases, veterans may develop moral injury (MI) symptoms that transcend and/or overlap with mental health conditions such as posttraumatic stress disorder (PTSD) and major depressive disorder (MDD). Further, PTSD and MDD are 2 established risk factors for chronic pain. However, research has not examined the association between MI symptoms and chronic pain. We tested whether MI would emerge as a salient correlate of concurrent reports of chronic pain in the presence of PTSD and MDD symptom severity among 59 veterans seeking integrated behavioral health care. Findings indicated the severity of MI symptoms was significantly linked with veterans' concurrent reports of chronic pain. Self-directed MI symptoms emerged as a correlate of worse pain in the presence of PTSD and MDD. Preliminary findings demonstrate possible associations between MI and chronic pain among veterans with a need for holistic health care. Future research should examine mechanisms for an apparent MI-chronic pain link. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
