RESUMO
Following treatment, cancer survivors often experience pain that negatively impacts their quality of life. Although both anxiety and fear of cancer recurrence (FCR) have been shown to exacerbate pain interference, less is known about either the temporal relationship between anxiety/FCR and pain interference or modifiable cognitive/emotional factors that might moderate that relationship among cancer survivors. This longitudinal study aims to advance our understanding of the impact of both anxiety and FCR following primary cancer treatment on subsequent pain interference. We also examined potentially modifiable moderators (i.e., cancer-related illness beliefs and emotion regulation difficulties) of the relationship between anxiety/FCR and subsequent pain interference. Adults (N = 397; 67% female; Mage = 59.1 years) diagnosed with breast, colorectal, or prostate cancer completed self-report measures at baseline (average of 2.5 months following treatment completion) and at 6-month follow-up. Both greater anxiety and FCR not only predicted subsequent pain interference, but also predicted increases in pain interference over time. Additionally, complex interaction patterns were observed between anxiety and the potential moderators on pain interference. Specifically, lower Personal Control beliefs and higher Consequences beliefs were associated with greater pain interference for those with lower levels of anxiety/FCR. Emotion regulation difficulties also moderated the anxiety-pain interference link (i.e., was more strongly associated with greater pain interference at lower levels of anxiety), but not the FCR-pain link. Chronicity beliefs did not interact with anxiety or FCR in predicting pain interference. This study advances our understanding of the role of anxiety/FCR on pain interference over time as well as potential psychological treatment targets for individuals at greater risk for longer-term pain following cancer treatment.
RESUMO
Introduction: Chronic pain affects a wide range of physical and psychological aspects of life for those impacted. Psychosocial treatment approaches may be of support, but outreach is still limited. Objectives: To evaluate the efficacy of EPIO, an evidence-informed, user-centered digital self-management intervention for people with chronic pain, in a 12-month randomized controlled trial. Methods: People living with chronic pain (N = 266) were randomized to the EPIO intervention (n = 132) or a usual-care control group (n = 134). The intervention was delivered in a simple blended care model, and outcome measures collected at baseline, 6 months, and 12 months. Generalized linear models for repeated measures were fitted to compare groups over time. Results: Participants were primarily female (81%), median age 49 years (range 22-78), with heterogeneous pain conditions, and had lived with pain >5 years (77.6%). A mixed linear model with all timepoints included revealed no statistically significant group differences for the primary outcome of pain interference. Significant psychological benefits in favor of the intervention group were however detected for depression (P = 0.022), self-regulatory fatigue (P = 0.024), vitality (P = 0.016), and mental health (P = 0.047). Baseline to 12-month changes showed additional favorable effects for anxiety (between-group mean differences [MDs] = 0.79, P = 0.047), depression (MD = 1.08, P = 0.004), self-regulatory fatigue (MD = 2.42, P = 0.021), pain catastrophizing (MD = 2.62, P = 0.009), and health-related quality of life. Conclusions: The EPIO program aims to improve outreach of evidence-based pain self-management interventions. Findings demonstrate how using EPIO can lead to sustainable psychological change, enhancing mental health and health-related quality of life for people suffering from pain, providing a chance to live well with the pain.
RESUMO
Measures of life outlook in older adults have been investigated in connection to pain, as both pain management and outlook are important factors of successful aging. We hypothesized that higher pain is associated with lower optimism among community-dwelling older adults. We utilized data from the UC San Diego Successful Aging Evaluation (SAGE), a prospective longitudinal cohort study initiated in 2010, to evaluate the relationship between pain and optimism in 378 community-dwelling adults aged ≥50 years. We used the revised Life Orientation Test (LOT-R) to measure optimism and three pain subscales-PROMIS Pain Interference, PROMIS Pain Intensity, and MOS 36-Item Short-Form Health Survey (SF-36)-as pain measures. Regression analyses reveal negative relationships between pain and optimism for all three pain scales, with regression coefficients of -0.277 (p < .0001), -0.246 (p < .0001), and 0.269 (p < .0001) respectively. This indicates value in considering physical and psychological elements in future intervention research to promote healthy aging.
RESUMO
PURPOSE OF REVIEW: The purpose of this narrative review is to summarize pain symptomatology and mechanisms in neurofibromatosis type 1 (NF1), discuss the pain related quality of life impacts of NF1, and discuss the literature exploring interventions to improve quality of life. RECENT FINDINGS: Chronic pain in NF1 is described as headache and non-headache pain. The literature describes mechanisms contributing to neuronal hyperexcitability in the setting of reduced neurofibromin as key contributors to pain in NF1. Pain in NF1 negatively impacts quality of life with pain interference, depression, anxiety, and cognitive functioning acting as important mediators. Mitogen-activated protein kinase (MEK) inhibitors are pharmacologic agents that interfere with pain mechanisms. Mind-body interventions improve coping skills to improve quality of life. Chronic pain in NF1 is heterogeneous with negative impacts on quality of life. New developments in pharmacological and non-pharmacological interventions offer promising approaches to pain management and quality of life improvement. Additional research is necessary to validate the use of MEK inhibitors and mind-body interventions in the treatment of NF1.
RESUMO
BACKGROUND: International focus groups with patients with idiopathic inflammatory myopathies (IIM) conducted by the OMERACT Myositis Working Group over the years demonstrated the pain as an important symptom experienced by these patients. In this study, we aimed to examine the frequency and degree of pain interference, the aspects of daily life impacted by pain, and the factors associated with pain interference in adults with IIM. METHODS: This was a prospective observational study with two visits. The patients who fulfilled the probable/definite IIM (ACR/EULAR Myositis Classification Criteria) were enrolled. Pain interference was assessed with PROMIS pain interference form (6a). Myositis core set measures and PROMIS fatigue (7a) and physical function (8b) were obtained at both visits. Logistic regression and linear mixed models were performed to assess the association between pain interference and other parameters. RESULTS: A total of 129 patients with IIM (60 % females) were recruited from U.S., South Korea, Netherlands, Sweden, and Australia. Approximately 71 % reported pain interference. The patients in the greater pain interference group were more likely to be female, had significantly worse patient/physician global disease activity, fatigue, and physical function than those in the lower pain interference group. The most commonly impacted life aspect was household chores. Manual muscle testing, patient/physician global disease activity, fatigue, and physical function were all significantly associated with pain interference score >60. CONCLUSION: The majority of the patients with IIM experience the impact of pain on their daily activities, particularly household chores. Myositis disease activity, duration, and subtype could be associated with greater pain interference.

U.S. Service members and Veterans (SM/V) experience elevated rates of traumatic brain injury (TBI), chronic pain, and other non-pain symptoms. However, the role of non-pain factors on pain interference levels remains unclear among SM/Vs, particularly those with a history of TBI. The primary objective of this study was to identify factors that differentiate high/low pain interference, given equivalent pain intensity among U.S. SM/V participating in the ongoing Long-term Impact of Military-relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium (LIMBIC-CENC) national multi-center prospective longitudinal observational study. An explainable machine learning was used to identify key predictors of pain interference conditioned on equivalent pain intensity. The final sample consisted of n = 1,577 SM/Vs who were predominantly male (87%), and 83.6% had a history of mild TBI(s) (mTBI), while 16.4% were TBI negative controls. The sample was categorized according to pain interference level (Low: 19.9%, Moderate: 52.5%, and High: 27.6%). Both pain intensity scores and pain interference scores increased with the number of mTBIs (p < 0.001), and there was evidence of a dose response between the number of injuries and pain scores. Machine learning models identified fatigue and anxiety as the most important predictors of pain interference, whereas emotional control was protective. Partial dependence plots identified that marginal effects of fatigue and anxiety were associated with pain interference (p < 0.001), but the marginal effect of mTBI was not significant in models considering all variables (p > 0.05). Non-pain factors are associated with functional limitations and disability experience among SM/V with an mTBI history. The functional effects of pain may be mediated through multiple other factors. Pain is a multi-dimensional experience that may benefit most from holistic treatment approaches that target comorbidities and build supports that promote recovery.
RESUMO
OBJECTIVES: Motoric cognitive risk syndrome (MCR) is a pre-dementia condition characterized by subjective complaints in cognition and slow gait. Pain interference has previously been linked with cognitive deterioration; however, its specific relationship with MCR remains unclear. We aimed to examine how pain interference is associated with concurrent and incident MCR. METHODS: This study included older adults aged ≥ 65 years without dementia from the Health and Retirement Study. We combined participants with MCR information in 2006 and 2008 as baseline, and the participants were followed up 4 and 8 years later. The states of pain interference were divided into 3 categories: interfering pain, non-interfering pain, and no pain. Logistic regression analysis was done at baseline to examine the associations between pain interference and concurrent MCR. During the 8-year follow-up, Cox regression analysis was done to investigate the associations between pain interference and incident MCR. RESULTS: The study included 7120 older adults (74.6 ± 6.7 years; 56.8% females) at baseline. The baseline prevalence of MCR was 5.7%. Individuals with interfering pain had a significantly increased risk of MCR (OR = 1.51, 95% CI = 1.17-1.95; p = 0.001). The longitudinal analysis included 4605 participants, and there were 284 (6.2%) MCR cases on follow-up. Participants with interfering pain at baseline had a higher risk for MCR at 8 years of follow-up (HR = 2.02, 95% CI = 1.52-2.69; p < 0.001). CONCLUSIONS: Older adults with interfering pain had a higher risk for MCR versus those with non-interfering pain or without pain. Timely and adequate management of interfering pain may contribute to the prevention and treatment of MCR and its associated adverse outcomes.

OBJECTIVES: Pain is increasingly becoming common among middle-aged and older adults. While research on the association between pain characteristics and sleep problems (SP) is limited in low- and middle-income countries, the underlying mechanisms of the association are poorly understood. This study examines the association of bodily pain intensity and pain interference with SP and investigates the mediating role of activity limitation and emotional distress in this association. METHODS: We analyzed population-based data, including 1,201 individuals aged ≥50 (mean [SD] age 66.14 [11.85] years) from the 2016-2018 AgeHeaPsyWel-HeaSeeB study in Ghana. Multiple OLS regressions and serial multiple mediation modeling using bootstrapping analyses examined direct and indirect effects from pain to SP through activity limitation and emotional distress. RESULTS: Regressions demonstrated that pain intensity and interference were significantly associated with higher levels of activity limitation, emotional distress, and SP (range: ß = 0.049-0.658). Bootstrapping analysis showed that activity limitation and emotional distress serially mediated the relationship between pain intensity and SP (total effect: ß = 0.264, Bootstrap 95% confidence interval [CI] = 0.165-0.362; direct effect: (ß = 0.107, Bootstrap 95% CI = 0.005-0.210; total indirect effect: ß = 0.156, Bootstrap 95% CI = 0.005-0.210) accounting for â¼59%. Activity limitation and emotional distress mediated pain interference and SP association (total effect: ß = 0.404, Bootstrap 95% CI = 0.318-0.490; direct effect: ß = 0.292, Bootstrap 95% CI = 0.201-0.384; and total indirect effect: ß = 0.112, Bootstrap 95% CI = 0.069-0.156) yielding â¼28%. CONCLUSION: Our data suggest that activity limitation and emotional distress may convey stress-related risks of pain on SP. Future research should evaluate if activity limitation and emotional distress could be effective targets to reduce the effect of pain on sleep in later-life.
RESUMO
INTRODUCTION: Long-term analgesic effect of intrathecal baclofen was reported in individuals with spinal cord injury. We conducted a prospective study to evaluate the effect of intrathecal baclofen on subtypes of neuropathic pain and its interference with general activity. MATERIALS AND METHODS: Nine spinal cord injury individuals who presented with severe spasticity and moderate to severe neuropathic pain received intrathecal baclofen via an implanted pump. We applied the ASIA Impairment Scale to assess spinal cord injury severity. Neuropathic pain was evaluated by numerical rating scale, Neuropathic Pain Symptom Inventory, and Brief Pain Inventory. Evaluations were performed at baseline and after at least 6 months of continuous intrathecal baclofen treatment. RESULTS: Intrathecal baclofen led to significant pain reduction as measured by numerical rating scale, Neuropathic Pain Symptom Inventory, and Brief Pain Inventory (p < 0.05). Improvements were significant for paroxysmal pain and dysesthesia and for pain interference with general activity, as assessed by the Brief Pain Inventory (p < 0.05). There was a significant relationship between the time since spinal cord injury and changes in paroxysmal pain as well as in the total Neuropathic Pain Symptom Inventory score (p < 0.05). The baclofen dose correlated also to the percentage changes in neuropathic pain improvement and sleep (p < 0.003). CONCLUSIONS: The present results provide evidence that intrathecal baclofen effectively reduces neuropathic pain, particularly paroxysmal pain and dysesthesia, and improves pain interference and overall well-being in individuals with spinal cord injury. Clinicians should be aware of this less well-known beneficial effect of intrathecal baclofen and should consider such a treatment option for better control of neuropathic pain in individuals with spinal cord injury.
RESUMO
Chronic pain and posttraumatic stress disorder symptoms (PTSS) co-occur at high rates in youth and are linked to worse pain outcomes and quality of life. While peer victimization has been posited as a mechanism underlying the PTSS-pain relationship in youth, empirical evidence suggests that it may exacerbate both PTSS and pain. The present study aimed to longitudinally examine PTSS as a mediator in the relationship between peer victimization at baseline and pain-related outcomes at 3 months in youth with chronic pain. Participants included 182 youth aged 10 to 18 years recruited from a tertiary-level children's hospital in Western Canada. At baseline, participants completed measures to assess pain (intensity and interference), peer victimization (relational and overt), and PTSS. The pain was reassessed at a 3-month follow-up. Primary hypotheses were tested utilizing a series of mediation analyses with PTSS as a proposed mediator in the associations between peer victimization and pain outcomes. Youth PTSS mediated the relationship between higher baseline relational victimization and higher 3-month pain interference while controlling for baseline pain interference. Three-month pain intensity was not correlated with peer victimization; thus, pain intensity was not included in the analyses. These findings reveal that PTSS may be an underlying factor in the co-occurrence of peer victimization and chronic pain in youth. Further research is needed to better understand the role of peer victimization in the maintenance of chronic pain to ensure appropriate, effective, and timely interventions that address the social and mental health issues impacting the lives of these youth as well as their pain. PERSPECTIVE: PTSS may be an underlying factor in the co-occurrence between peer victimization and chronic pain in youth, highlighting the need to assess for both peer relationship problems and PTSS in youth with chronic pain.
RESUMO
BACKGROUND: Chronic pain affects approximately 8 million Canadians (~20%), impacting their physical and mental health while burdening the health care system with costs of upwards of US $60 billion a year. Indeed, patients are often trialed on numerous medications over several years without reductions to their symptoms. Therefore, there is an urgent need to identify new therapies for chronic pain to improve patients' quality of life, increase the availability of treatment options, and reduce the burden on the health care system. OBJECTIVE: The primary objective of this study is to examine the feasibility of a parallel 3-arm pilot randomized controlled trial whereby patients are randomized to either intravenous ketamine alone, cognitive behavioral therapy (CBT) and mindfulness meditation (MM) training (CBT/MM), or the combination of intravenous ketamine and CBT/MM. The secondary outcome is to assess the durability and efficacy of combination intravenous ketamine and CBT/MM for treatment of chronic pain as compared to CBT/MM or intravenous ketamine alone (assessed at week 20 of the study). METHODS: This is a single-center, 16-week, 3-arm pilot study that will take place at the Chronic Pain Clinic at St. Michael's Hospital, Toronto, Ontario, which receives 1000 referrals per year. Patients will be enrolled in the study for a total of 20 weeks. Participants who are allocated CBT/MM therapy will receive remote weekly psychotherapy from week 1 to week 16, inclusive of health coaching administered through the NexJ Health Inc (NexJ Health) platform. Patients who are allocated ketamine-infusion therapy will receive monthly ketamine infusion treatments on weeks 2, 7, and 12. Patients who are allocated ketamine+CBT/MM will receive weekly psychotherapy from weeks 1 to 16, inclusive, as well as ketamine infusion treatments on weeks 2, 7, and 12. We will be assessing recruitment rates, consent rates, withdrawal rates, adherence, missing data, and adverse events as pilot outcome measures. Secondary clinical outcomes include changes relative to baseline in pain intensity and pain interference. RESULTS: As of November 1, 2023, the recruitment process has not been initiated. Given the recruitment, consent, and intervention target of 30 participants for this feasibility study, with each patient undergoing monitoring and treatments for a course of 20 weeks, we expect to complete the study by December 2025. CONCLUSIONS: This study assesses the feasibility of conducting a 3-arm randomized controlled trial to examine the effects of ketamine administration with the concurrent use of CBT/MM in a population with chronic neuropathic pain. The results of this pilot randomized controlled trial will inform the development of a larger-scale randomized controlled trial. Future studies will be aimed at including a sufficiently powered sample that will inform decisions about optimal treatment calibration and treatment effect duration.

RESUMO
Background The Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference and pain intensity measures quantify separate dimensions of pain from the patient's perspective. This study aimed to assess differences in these outcomes and to evaluate whether baseline PROMIS pain scores could be used as a leading indicator of increased pain and opioid consumption during early recovery after lumbar fusion. Methods A retrospective review of 199 consecutive patients undergoing posterolateral fusion (PLF) at a single institution was performed. All patients underwent one to three level lumbar PLF and preoperatively completed the PROMIS pain intensity and PROMIS pain interference measures. Multivariate linear regression was used to assess the relationship between preoperative PROMIS scores and postoperative pain numeric rating scale (NRS) and oral morphine milligram equivalents (OMME) by day after controlling for age, sex, and body mass index (BMI). Results In comparison to patients with the lowest preoperative pain intensity scores, those with the highest scores required significantly more OMME on postoperative day (POD) zero and one (both p<0.05) and had higher pain NRS on POD one (p=0.02). Patients with the highest pain interference scores reported higher pain NRS on POD zero (p=0.02) but required similar OMME at all time points. After controlling for age, sex, and BMI, each one-point increase in preoperative PROMIS pain interference scores was associated with increased OMME on POD zero (ß=0.29, p=0.04) and POD one (ß=0.64, p=0.03). Conclusions Patients with high pain intensity reported higher levels of pain and required more opioids during the first 24 hours postoperatively, while those with high pain interference reported higher levels of pain on the day of surgery but utilized similar amounts of opioids. After risk adjustment, increased baseline PROMIS pain interference scores - but not pain intensity - were associated with increased opioid use. These results suggest that both measures should be considered when identifying patients at risk for increased pain and opioid consumption after PLF.
RESUMO
BACKGROUND: Posttraumatic stress disorder (PTSD) symptoms and pain are highly prevalent and comorbid, particularly in veterans, but mechanisms explaining their linkage remain unclear. The aims of this study were to determine: (1) whether sleep impairment and physical activity (PA) mediate relations between PTSD symptoms and pain interference (assessed both longitudinally and as residual change) and (2) the unique roles of each PTSD symptom cluster in those relationships. METHODS: The present study is a secondary analysis of a longitudinal observational investigation of 673 post-9/11 veterans (45.8% women). Surveys were administered at baseline and 3-month and 6-month follow-ups. RESULTS: PTSD symptoms were significantly associated with pain interference longitudinally and worsening pain interference over time. Sleep impairment, but not PA, significantly mediated the relationship between PTSD symptoms and subsequent pain interference. Hyperarousal symptoms were found to be the primary driver of the relationship between PTSD symptoms and pain interference and re-experiencing symptoms were associated with change in pain interference via sleep impairment. Men and women did not differ on any of the study variables with the exception of PA. CONCLUSION: Findings underscore the importance of targeting sleep as a key modifiable health factor linking PTSD symptoms to pain interference in post-9/11 veterans.
RESUMO
Breast cancer patients experience treatment-related pain from surgery, radiation, chemotherapy, and long-term hormonal treatment, which can lead to poorer outcomes. Patient and family caregivers' psychosocial distress exacerbates patient pain interference, but this has not been directly examined among breast cancer patients in dyadic models longitudinally. Guided by a biopsychosocial framework, the Biobehavioral Family Model, we explore how multiple reports of patient pain interference across the first year of treatment are linked to the patient (N = 55) and caregiver (N = 55) pretreatment psychosocial distress (eg, depression, anxiety, marital satisfaction, family relationship quality). Specifically, we find that breast cancer patients' pain interference increases and then decreases over the first year of treatment. Additionally, caregivers' pretreatment anxiety was associated with increased patient pain interference over time (B = .19, SE = .07, P = .008), while patients' pretreatment psychosocial distress was not associated with a change in their pain interference. Yet, looking at clinically specific times during the first year of treatment, we find that caregiver-reported higher marital satisfaction is associated with lower patient-reported pain interference later in treatment (6 months: B = -.58, SE = .24, P = .017; 12 months: B = -.82, SE = .23, P < .001). We conclude that, per the Biobehavioral Family Model, pretreatment patient and caregiver psychosocial distress is linked to patient pain interference during the first year of breast cancer treatment. Thus, caregivers' psychosocial distress (ie, anxiety and marital satisfaction) may be a particularly important target in future dyadic behavioral intervention strategies to reduce breast cancer patient pain. PERSPECTIVE: This article presents the link between breast cancer patients and family caregiver pretreatment psychosocial distress (anxiety, depression, marital satisfaction, and family quality) on patient pain interference during 1 year of breast cancer treatment. Findings suggest that caregiver anxiety and marital satisfaction may be important targets for future dyadic behavioral pain interventions.

Aim: Oral cancer patients suffer pain at the site of the cancer, which degrades quality of life (QoL). The University of California San Francisco Oral Cancer Pain Questionnaire (UCSFOCPQ), the only validated instrument specifically designed for measuring oral cancer pain, measures the intensity and nature of pain and the level of functional restriction due to pain. Purpose: The aim of this study was to compare pain reported by untreated oral cancer patients on the UCSFOCPQ with pain they reported on the Brief Pain Inventory (BPI), an instrument widely used to evaluate cancer and non-cancer pain. Patients and Methods: The correlation between pain measured by the two instruments and clinical characteristics were analyzed. Thirty newly diagnosed oral cancer patients completed the UCSFOCPQ and the BPI. Results: Pain severity measurements made by the UCSFOCPQ and BPI were concordant; however, the widely used BPI average pain over 24 hours score appeared less sensitive to detect association of oral cancer pain with clinical characteristics of patients prior to treatment (nodal status, depth of invasion, DOI). A BPI average score that includes responses to questions that measure both pain severity and interference with function performs similarly to the UCSFOCPQ in detection of associations with nodal status, pathologic T stage (pT stage), stage and depth of invasion (DOI). Conclusion: Pain assessment instruments that measure sensory and interference dimensions of oral cancer pain correlate with biologic features and clinical behavior.
RESUMO
BACKGROUND: The relationships between opioid use disorder (OUD), chronic pain, and mental health distress are complex and multidirectional. The objective of this exploratory study was to examine the relationship between mental health conditions and Chronic pain severity and interference among patients stabilized on either buprenorphine or methadone. METHODS: We report baseline data from a randomized trial of a mind-body intervention conducted at 5 outpatient clinics that provided either buprenorphine or methadone treatment. Validated scales were used to measure substance use, mental health distress, and pain severity and interference. Statistical analyses examined the relationship between mental health conditions and pain severity and interference. RESULTS: Of 303 participants, 57% (n = 172) reported Chronic pain. A total of 88% (n = 268) were prescribed buprenorphine. Mental health conditions were common, with one-quarter of the sample screening positive for all 3 mental health conditions (anxiety, depression, and posttraumatic stress disorder [PTSD]). Compared to participants without Chronic pain, participants with Chronic pain were more likely to screen positive for moderate-severe anxiety (47% vs 31%); moderate-severe depression (54% vs 41%); and the combination of anxiety, depression, and PTSD (31% vs 18%). Among participants with Chronic pain, mental health conditions were associated with higher pain interference. Pain severity was higher among participants with mental health conditions, but only reached statistical significance for depression. Pain interference scores increased with a higher number of co-occurring mental health conditions. CONCLUSIONS: Among individuals stabilized on either buprenorphine or methadone, highly symptomatic and comorbid mental health distress is common and is associated with increased pain interference. Adequate screening for, and treatment of, mental health conditions in patients with OUD and Chronic pain is needed.

Pain interferes with one's work and social life and, at a personal level, daily activities, mood, and sleep quality. However, little research has been conducted on pain interference and its socioecological determinants among the working poor. Noting the clinical/policy decision needs and the technical challenges of isolating the intricately interrelated socioecological factors' unique contributions to pain interference and quantifying the relative contributions of each factor in an interpretable manner to inform clinical and policy decision-making, we deployed a novel random forest algorithm to model and quantify the unique contribution of a diverse ensemble of environmental, sociodemographic, and clinical factors to pain interference. Our analyses revealed that features representing the internal built environment of the working poor, such as the size of the living space, air quality, access to light, architectural design conducive to social connection, and age of the building, were assigned greater statistical importance than other more commonly examined predisposing factors for pain interference, such as age, occupation, the severity and locations of pain, BMI, serum blood sugar, and blood pressure. The findings were discussed in the context of their benefit in informing community pain screening to target residential areas whose built environment contributed most to pain interference and informing the design of intervention programs to minimize pain interference among those who suffered from chronic pain and showed specific characteristics. The findings support the call for good architecture to provide the spirit and value of buildings in city development.

Although chronic orofacial pain (COFP) is common among older adults, the role of psychological factors in pain outcomes among this population has received limited attention. This study examined the role of anxiety and pain catastrophizing, two corelates of pain in other populations, in pain intensity and interference among 166 older adults with COFP (79% female, Mage = 68.84, SD = 5.56). Participants completed an online survey including measures of anxiety, pain catastrophizing, and pain intensity/interference. We applied mediation analyses to test indirect associations between anxiety and pain outcomes via pain catastrophizing. Results indicated that anxiety was positively associated with pain intensity and pain interference (bs = .70-1.12, ps < .05). There was also an indirect association between anxiety and pain interference through pain catastrophizing (b = .35, 95% CI [.0383, .7954]), indicating pain catastrophizing partially accounts for this relationship. Assessing and addressing anxiety and pain catastrophizing has the potential to improve treatment outcomes in this population.

Introduction: Previous studies suggest an association between cognitive flexibility and development of chronic pain after surgery. It is not known whether cognitive flexibility can be improved in patients with chronic pain. Objectives: This study tested whether a neurocognitive training program results in improved cognitive flexibility and pain in patients with chronic pain. Methods: We conducted a single-center, prospective, randomized study investigating 5-week daily neurocognitive training in patients with chronic pain. Participants (n = 145) were randomized into neurocognitive training or care as usual, and they completed assessments at baseline, posttreatment, and 3 months. The treatment group was asked to spend 35 minutes daily completing a program with tasks on cognitive flexibility, memory, attention, and speed. The primary outcome was performance on the neurocognitive performance test (NCPT). Secondary outcomes included levels of pain interference and severity. Results: At 5 weeks, the treatment group showed greater improvements on NCPT compared with the control group (d = 0.37); effect size was smaller at 3 months (d = 0.18). The treatment group reported lower pain severity at 5 weeks (d = 0.16) and 3 months (d = 0.39) than the control group, but pain interference was only lower at 3 months (d = 0.20). Conclusions: Outcomes suggest that using neurocognitive training to modify cognitive flexibility in patients with chronic pain may improve pain severity. This study provided effect size estimates to inform sample size calculations for randomized controlled trials to test the effectiveness of neurocognitive interventions for the prevention and treatment of chronic pain.
RESUMO
Many studies have shown that the prevalence of degenerative spinal cord compression increases with age. However, most cases at early stages are asymptomatic, and their diagnosis remains challenging. Asymptomatic cervical spinal cord compression (ASCC) patients are more likely to experience annular tears, herniated disks, and later develop symptomatic compression. Asymptomatic individuals do not typically undergo spinal cord imaging; therefore, an assessment test that is both sensitive and specific in diagnosing ASCC may be helpful. It has been demonstrated that the Patient Reported Outcome Measure Information System (PROMIS) mobility test is sensitive in detecting degenerative cervical myelopathy (DCM) symptoms. We investigated the use of the PROMIS mobility test in assessing clinical dysfunction in ASCC. In this study, 51 DCM patients and 42 age-matched healthy control (HC) were enrolled. The degree of cervical spinal cord compression was assessed using the high-resolution cervical spinal cord T2 Weighted (T2w) MRIs, which were available for 14 DCM patients. Measurements of the spinal cords anterior-posterior (AP) diameter at the region(s) that were visibly compressed as well as at different cervical spine levels were used to determine the degree of compression. The age-matched HC cohort had a similar MRI to establish the normal range for AP diameter. Twelve (12) participants in the HC cohort had MRI evidence of cervical spinal cord compression; these individuals were designated as the ASCC cohort. All participants completed the PROMIS mobility, PROMIS pain interference (PI), PROMIS upper extremity (UE), modified Japanese orthopedic association (mJOA), and neck disability index (NDI) scoring scales. We examined the correlation between the AP diameter measurements and the clinical assessment scores to determine their usefulness in the diagnosis of ASCC. Furthermore, we examine the sensitivity and specificity of PROMIS mobility test and mJOA. Compared to the HC group, the participants in the ASCC and DCM cohorts were significantly older (p = 0.006 and p < 0.0001, respectively). Age differences were not observed between ASCC and DCM (p > 0.999). Clinical scores between the ASCC and the HC group were not significantly different using the mJOA (p > 0.99), NDI (p > 0.99), PROMIS UE (p = 0.23), and PROMIS PI (p = 0.82). However, there were significant differences between the ASCC and HC in the PROMIS mobility score (p = 0.01). The spinal cord AP diameter and the PROMIS mobility score showed a significant correlation (r = 0.44, p = 0.002). Decreasing PROMIS mobility was significantly associated with a decrease in cervical spinal cord AP diameter independent of other assessment measures. PROMIS mobility score had a sensitivity of 77.3% and specificity of 79.4% compared to 59.1% and 88.2%, respectively, for mJOA in detecting cervical spinal cord compression. Certain elements of ASCC are not adequately captured with the traditional mJOA and NDI scales used in DCM evaluation. In contrast to other evaluation scales utilized in this investigation, PROMIS mobility score shows a significant association with the AP diameter of the cervical spinal cord, suggesting that it is a sensitive tool for identifying early disability associated with degenerative change in the aging spine. In a comparative analysis of PROMIS mobility test against the standard mJOA, the PROMIS mobility demonstrated higher sensitivity for detecting cervical spinal cord compression. These findings underscore the potential use of PROMIS mobility score in clinical evaluation of the aging spine.
