Do Maladaptive Imaging Beliefs Predict Self-Reported Pain Interference and Physical Function in Patients With Musculoskeletal Disorders?

OBJECTIVE: To determine if maladaptive imaging beliefs correlated with, and predicted pain interference and physical function outcomes in people with musculoskeletal pain disorders. DESIGN: A prospective cohort study of patients with musculoskeletal disorders receiving outpatient physical therapy from April 2022 to August 2023. METHODS: Four questions about imaging were asked to assess maladaptive beliefs, the need to rule out serious conditions, guide treatment, determine diagnosis, and validate symptoms. Correlations with beliefs and outcomes were assessed using Kendall's tau rank and Spearman's rho correlation coefficients. Generalized linear models determined if these beliefs predicted outcomes at baseline and 6 weeks. RESULTS: The cohort included 152 participants (mean [standard deviation] age: 56.13 [15.13]; 32.2% male). Maladaptive imaging beliefs correlated positively with pain interference and negatively with physical function. The need to rule out serious conditions and validate symptoms correlated with pain interference (range: τb = 0.17, 0.20; P = .003, .0121) and physical function (range: ρ = -0.22, -0.22; P = .006, .008). All but 1 belief correlated with pain interference (range: τb = 0.19, 0.24; P<.001, .004) and physical function (range: ρ = -0.26, -0.21; P = .001, .009) at 6 weeks. Each additional belief slightly increased pain interference at 6 weeks (β = 0.01; 95% CI: 0.001, 0.03; P = .04) and lowered physical function at both baseline (β = -0.97; 95% CI: -1.66, -0.28; P = .01) and 6 weeks (β = -0.76; 95% CI: -1.37, -0.15; P = .02). CONCLUSION: Maladaptive imaging beliefs were significantly (albeit weakly) correlated with pain and physical function. Each additional maladaptive imaging belief increased pain interference at 6 weeks and lowered physical function at baseline and 6 weeks. Beliefs about the necessity of imaging to properly manage musculoskeletal disorders may influence outcomes. J Orthop Sports Phys Ther 2024;54(9):1-10. Epub 5 July 2024. doi:10.2519/jospt.2024.12625.

Pain Interference Prior to and 1 Year After Surgery for Adult Traumatic Brachial Plexus Injury

Pain after brachial plexus injury (BPI) can be severely debilitating and is poorly understood. We hypothesized that pain interference (PI) ("the extent to which pain hinders engagement in life") would be predicted by depression, anxiety, severity of pain symptoms, and poorer preoperative muscle function. Among patients in a prospective multicenter BPI cohort study, 37 completed Patient-Reported Outcomes Measurement Information System (PROMIS) PI questionnaires before and 1 year after surgery. At both times, participants completed anxiety and depression questionnaires and BPI-specific measures of pain symptoms, physical limitations, and emotional recovery. Surgeon-graded muscle testing, injury severity, age at the time of injury, body mass index, and time from injury to surgery were included. We performed a bivariate analysis of predictors for preoperative and 1-year PROMIS PI followed by multivariable regression modeling using stepwise selection and Bayesian Information Criterion to select covariates. Before surgery, the mean PROMIS PI score was 60.8 ± 11.0, with moderate correlations between PROMIS PI and depression, as well as between PROMIS PI and functional limitations. At 1 year after surgery, the mean PROMIS PI score was 59.7 ± 9.5. There was no difference in preoperative and 1-year PROMIS PI. There were strong correlations between PROMIS PI and pain symptoms, functional limitations, and emotional aspects of recovery at the 1-year follow-up that remained significant in multivariable regression. There were no notable associations between muscle testing and PI. Pain interference remained substantial and elevated in BPI patients 1 year after surgery. We noted strong associations between PI and pain symptoms, functional limitations, and emotional aspects of recovery. These findings demonstrate the persistence of pain as a feature throughout life after BPI and that its treatment should be considered a priority alongside efforts to improve extremity function.

Disparities in Surgical Intervention and Health-Related Quality of Life Among Racial/Ethnic Groups With Degenerative Lumbar Spondylolisthesis.

Racial and socioeconomic disparities in spine surgery for degenerative lumbar spondylolisthesis persist in the United States, potentially contributing to unequal health-related quality of life (HRQoL) outcomes. This is important as lumbar spondylolisthesis is one of the most common causes of surgical low back pain, and low back pain is the largest disabler of individuals worldwide. Our objective was to assess the relationship between race, socioeconomic factors, treatment utilization, and outcomes in patients with lumbar spondylolisthesis. This cohort study analyzed prospectively collected data from 9941 patients diagnosed with lumbar spondylolisthesis between 2015 and 2020 at 5 academic hospitals. Exposures were race, socioeconomic status, health coverage, and HRQoL measures. Main outcomes and measures included treatment utilization rates between racial groups and the association between race and treatment outcomes using logistic regression, adjusting for patient characteristics, socioeconomic status, health coverage, and HRQoL measures. Of the 9941 patients included (mean [SD] age, 67.37 [12.40] years; 63% female; 1101 [11.1%] Black, Indigenous, and People of Color [BIPOC]), BIPOC patients were significantly less likely to use surgery than White patients (odds ratio [OR] = 0.68; 95% CI, 0.62-0.75). Furthermore, BIPOC race was associated with significantly lower odds of reaching the minimum clinically important difference for physical function (OR = 0.74; 95% CI, 0.60; 0.91) and pain interference (OR = 0.77; 95% CI, 0.62-0.97). Medicaid beneficiaries were significantly less likely (OR = 0.65; 95% CI, 0.46-0.92) to reach a clinically important improvement in HRQoL when accounting for race. This study found that BIPOC patients were less likely to use spine surgery for degenerative lumbar spondylolisthesis despite reporting higher pain interference, suggesting an association between race and surgical utilization. These disparities may contribute to unequal HRQoL outcomes for patients with lumbar spondylolisthesis and warrant further investigation to address and reduce treatment disparities.

Matching males and females undergoing non mesh primary unilateral inguinal hernia repair: evaluating sex differences in preoperative and acute postoperative pain.

The objective was to compare pain and related psychological factors during the preoperative and acute postoperative period between male and female patients, who underwent non mesh primary unilateral inguinal hernia repair. After ethics approval, informed consent was obtained, and data were collected. Male and female participants were compared by manually matching one-to-one on 10 variables. Descriptive statistics (mean ± standard deviation and frequency) as well as numerical rating scales from 0 to 10 were used. Comparison tests were performed using Chi-square or Fisher's Exact test for categorical data and independent samples t-test or non-parametric equivalent tests for numerical scores. p < 0.05 is reported as statistically significant. To control type I error, Bonferroni correction was used. 72 participants with 36 matched pairs were included. Sex differences were found for operation length (p = .006), side of operation (p = .002), and hernia type (p = .013). Significant differences between the sexes were not found at the preoperative or postoperative time for resilience, pain interference or pain severity related measures, postoperative hernia pain incidence, pain catastrophizing, depression and anxiety symptoms, or return to normal activities. When controlling for known confounders and using a conservative Type I error rate, pain and related factors between the sexes did not differ significantly.

Patients Undergoing Hip Arthroscopy With Concomitant Periacetabular Osteotomy Demonstrate Clinically Meaningful Improvement at 2 Years Using the Patient-Reported Outcome Measurement Information System and International Hip Outcome Tool 12

PurposeTo report the minimal clinically important difference (MCID) and substantial clinical benefit (SCB) values using the Patient-Reported Outcome Measurement Information System (PROMIS) and International Hip Outcome Tool 12 (iHOT-12) in patients undergoing hip arthroscopy (HA) with concomitant periacetabular osteotomy (PAO), HA+PAO for acetabular dysplasia and intra-articular pathology with minimum 2-year follow up. MethodsData from patients who underwent HA+PAO was prospectively collected and retrospectively analyzed. Inclusion criteria consisted of patients who had a diagnosis of hip dysplasia or hip instability and had minimum 2-year PROMs follow up. Data was collected electronically preoperatively and postoperatively at 6 months, 1year, and 2 years. Outcome measures analyzed were the iHOT -12 and PROMIS computer adaptive tests (CAT): Physical Function (PF), Pain Interference (PI), and Global Physical Health (GPH). MCID and SCB were calculated for these measures. Results106 patients were included in the study with an average age of 23.5 ± 6.6, an average body mass index (BMI) of 24.3, and the majority being female (94%). The values for MCID were calculated to be 40.9, 40.7, 60.2, and 43.5 and the percentage achieving MCID at 2 years was 82.6%, 82.9%, 79.6%, and 80.1% for the iHOT-12, PROMIS-PF, PROMIS-PI, and PROMIS-GPH respectively. The 1 year and 2-year SCB scores for ≥ 80% satisfaction and percent achieving were as follows respectively: iHOT-12 (71.8 (60.3%), 61.9 (65.1%)); PROMIS-PF (47.1 (64.2%), 47.2 (71.7%)); PROMIS-PI (50.6 (48.1%), 52.3 (49.1%)); PROMIS-GPH (49.3 (54.7%), 49.3 (55.7%)). The 1 year and 2 year SCB scores for 100% satisfaction and percent achieving were as follows respectively: iHOT-12 (80.2 (44.3%), 81.3 (47.2%)); PROMIS-PF (50.7 (46.2%), 50.3 (56.6%)); PROMIS-PI (52.4 (34.9%), 52.4 (49.1%)); PROMIS-GPH (52.5 (36.8%), 49.3 (55.7%)). ConclusionThis study reports values for MCID and SCB for PROMIS and iHOT-12 at 2-year follow up in patients undergoing HA+PAO for hip dysplasia or instability. The percentage of patients achieving MCID ranged from 79.6%-82.9% at 2-year follow-up. In addition, the percentage of patients achieving SCB at 2-year follow up for ≥ 80% satisfaction ranged from 49.1%-71.2% and the percentage for 100% satisfaction ranged from 49.1%-56.6%

The Impact of Blood Flow Restriction Training on Tibial Bone Stress Injury Rehabilitation: An Exploratory Case Series.

Lower extremity bone stress injuries (BSI) are common injuries among athletes and military members. Typical management involves a period of restricted weightbearing which can have rapid detrimental effects upon both muscle and bone physiology. Few studies have investigated the effect of blood flow restriction (BFR) training on bone in the rehabilitative setting. The purpose of this study was to investigate the effects of lower extremity exercise with the addition of BFR upon bone mineral density, bone mineral content, and lean body mass in military members with tibial BSIs. Case series. Twenty military members with MRI-confirmed tibial BSI were recruited to complete lower extremity exercise with the addition of BFR twice per week for four weeks. The BFR cuff was applied proximally to the participant's involved limb while they performed gluteal, thigh, and leg resistance exercises. Outcomes were assessed at baseline and four weeks. The primary outcomes were whole leg bone mineral density (BMD), bone mineral content (BMC), and lean body mass (LM) as measured by dual-energy x-ray absorptiometry. Secondary outcomes included thigh and leg circumference measures and patient-reported outcomes, including the Lower Extremity Functional Scale (LEFS), Patient-Reported Outcomes Measurement Information System 57 (PROMIS-57), and Global Rating of Change (GROC). No significant differences were found in BMD (p=0.720) or BMC (p=0.749) between limbs or within limbs over time. LM was generally less in the involved limb (p=0.019), however there were no significant differences between or within limbs over time (p=0.404). For thigh circumference, significant main effects were found for time (p=0.012) and limb (p=0.015), however there was no significant interaction effect (p=0.510). No significant differences were found for leg circumference (p=0.738). Participants showed significant mean changes in LEFS (15.15 points), PROMIS physical function (8.98 points), PROMIS social participation (7.60 points), PROMIS anxiety (3.26 points), and PROMIS pain interference (8.39 points) at four weeks. The utilization of BFR in the early rehabilitative management of tibial BSI may help mitigate decrements in both bone and muscle tissue during periods of decreased physical loading. 4.

Pain Interference in Juvenile Idiopathic Arthritis.

Despite treatment advances, pain remains a serious problem for many children with juvenile idiopathic arthritis (JIA). To better understand pain in children with JIA and identify potentially modifiable factors, this study evaluated Patient-Reported Outcomes Measurement Information System (PROMIS) Pediatric Pain Interference (PI) and its relationships with other pain measures and demographic, clinical, psychosocial, and functional variables. This cross-sectional, observational, multicenter study used descriptive statistics and a mix of bivariate and multivariable analyses to describe PI and characterize relationships with other measures and variables. Among 355 children with JIA, 27% reported moderate or severe PI and 13.3% reported daily pain. PI correlated with other pain measures. Increasing age, decreasing disease duration, and increasing number of active joints, as well as presence of active disease, steroid treatment, and biologic treatment, were associated with greater PI. All PROMIS psychosocial and functional measures were associated with PI in the expected direction except for PROMIS Pediatric Physical Activity, which showed no association. In multivariable analyses, only PROMIS Fatigue, PROMIS Mobility, and the exploratory interaction of PROMIS Anxiety and disease-modifying antirheumatic drug treatment were significant. Moderate and severe PI was prevalent in this sample of children with JIA. PI increased with age and indicators of disease activity, but was more strongly associated with increasing fatigue and decreasing mobility. Findings support the use of PI as a short, easily administered multidimensional pain measure as part of routine clinical care. Fatigue, mobility, and disease activity should be assessed further when PI is high.

Sleeve gastrectomy prior to primary total hip and total knee arthroplasty is associated with increased risk of early complications

AimsThe purpose of this study was to determine the association between prior sleeve gastrectomy in patients undergoing primary total hip and knee arthroplasty, and 90-day complications, incidence of revision arthroplasty, and patient-reported outcome scores at final follow-up.MethodsThis is a retrospective, single-centre analysis. Patients undergoing primary hip or knee arthroplasty with a prior sleeve gastrectomy were eligible for inclusion (n = 80 patients). A morbidly obese control group was established from the same institutional registry using a 1:2 match, for cases:controls with arthroplasty based on propensity score using age, sex, pre-sleeve gastrectomy BMI, Current Procedural Terminology code to identify anatomical location, and presurgical haemoglobin A1C. Outcomes included 90-day complications, incidence of revision arthroplasty, and patient-reported outcome scores at final follow-up. Multivariable logistic regressions evaluated associations of underlying preoperative demographic and treatment characteristics with outcomes.ResultsComplications within 90 days of surgery were increased in the sleeve gastrectomy group relative to the obese control group after controlling for underlying preoperative demographic characteristics (odds ratio (OR) 4.00 (95% CI 1.14 to 13.9); p = 0.030). Postoperative revisions were similar in the sleeve gastrectomy group relative to the obese control group after controlling for underlying preoperative demographic characteristics (OR 17.8 (95% CI 0.64 to 494.3); p = 0.090). Patient-Reported Outcomes Measurement Information System (PROMIS) depression decreased by a greater amount from pre- to postoperative in the obese controls relative to the sleeve gastrectomy group (OR 4.04 (95% CI 0.06 to 8.02); p = 0.047). PROMIS pain interference and physical function change from pre- to postoperative was not associated with sleeve gastrectomy status.ConclusionWe found a higher rate of complications at 90 days in patients who underwent sleeve gastrectomy prior to primary hip or knee arthroplasty relative to a matched, obese control population. Prosthetic revision rates were similar between the two groups, while improvements in PROMIS depression scores were larger in the obese cohort. This study suggests that sleeve gastrectomy to achieve preoperative weight loss prior to arthroplasty surgery may not mitigate early complication risks in obese patient populations.Cite this article: Bone Joint J 2024;106-B(9):935–941.

Feasibility of Obtaining Patient-Reported Outcome Measures in a High-Volume Multidisciplinary Surgical Limb Salvage Center.

Completion of patient-reported outcome measures (PROMs) is labor-intensive but paramount in improving patient-centered care, allowing for advancement of techniques and scrutinization of outcomes. We report the feasibility of PROM collection and reporting for patients seen in a high-volume, multidisciplinary, tertiary limb salvage center to determine pain and functionality outcomes. The center received grant funding resources for large-scale PROM collection. Patients completed either tablet or paper surveys. Functionality and pain PROMs included 1) Neuro-QoL Lower Extremity Function-Mobility, 2) Numerical Rating Scale, 3) Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Intensity, and 4) PROMIS Pain Interference. Research assistants attended clinic daily to administer surveys. Patients were categorized into the following groups: amputation, flap reconstruction, other surgical management, and nonsurgical management. Five hundred sets of each survey were administered to 420 patients across 2 months, with 16% of patients (n = 80) completing multiple sets at separate visits. The completion rate among eligible patients was 90% or greater for each PROM. Of the respondents, 133 (31.7%) were seen for previous amputation, 32 (7.6%) for local or free flap reconstruction, 68 (16.2%) for other surgical management (eg, debridement, arthroplasty), and 295 (70.2%) for nonsurgical management (eg, lymphedema, hidradenitis). We report that integration of PROM collection in a high-volume limb salvage center is feasible. These metrics allow measurement of the impact and effectiveness of salvage or amputation surgeries from patients' perspectives, providing quantification of satisfaction and aspects of health-related quality of life, improved patient advocacy, and an evidence-based approach to surgical management.

Limited effects of phone coaching in an RCT of online self-guided acceptance and commitment therapy for chronic pain

IntroductionOver 80% of patients with Chiari Malformation (CM) struggle with moderate to severe disability due to neck pain and headaches. Self-guided online Acceptance and Commitment Therapy (ACT) is efficacious in addressing chronic pain. However, it is unclear whether adjunctive weekly phone coaching (a cost- and labor-intensive component of the intervention) contributes to, or provides additional benefit to, ACT's success. MethodThis study randomized 112 participants with CM to ACT + Coaching, ACT-Only, or WC (WC) groups. Participants completed a baseline survey, weekly assessments, a self-guided online ACT intervention, and a one-month follow-up survey. Primary outcomes were psychological flexibility (PF) and chronic pain acceptance; secondary outcomes included pain intensity, pain interference, depression, and anxiety. ResultsThere were no differences between the ACT + Coaching and ACT-Only groups on chronic pain acceptance, pain interference, or anxiety; however, there was a small but statistically significant effect favoring ACT + Coaching for depression and PF. Compared to the WC group, both the ACT + Coaching and ACT-Only groups significantly improved in chronic pain acceptance, and anxiety. Adherence was high (91% completed all sessions) and equivalent between conditions. Participants reported coaching was helpful and important, but there were no group differences in intervention satisfaction. DiscussionThere were no differences between treatment groups on most outcomes, intervention satisfaction, engagement, or adherence. Online ACT without adjunctive phone coaching may be a cost- and time-efficient option to address chronic pain acceptance and anxiety, but additional research is needed to establish and improve efficacy for other outcomes.

Health Care Discrimination Affects Patient Activation, Communication Self-Efficacy, and Pain for Black Americans

This study examines whether a key psychosocial factor—perceiving racial discrimination in health care—is associated with worse patient activation, communication self-efficacy, and physical health outcomes for Black veterans with chronic pain. Moreover, we explore the role of physician-patient working alliance as a moderator that may alleviate the potential consequences of perceiving racial discrimination. This work is a secondary analysis of baseline data from a clinical trial with 250 U.S. Black veterans with chronic musculoskeletal pain. Participants were recruited from primary care clinics at a Midwestern VA hospital between 2018 and 2021. Perceiving racial discrimination in health care was associated with lower patient activation, lower self-efficacy in communicating with one’s physician, higher pain intensity, and lower pain management self-efficacy (ps < .049) but was unrelated to reports of pain interference or use of pain coping strategies (ps > .157). Although the relationship between perceived discrimination and patient activation was moderated by working alliance (P = .014), having a stronger working alliance improved patient activation to varying degrees across levels of perceived discrimination (rather than buffering against negative outcomes when perceiving higher levels of discrimination). Moderation was not significant on any other measures. This study deepens our understanding of the broad range of health outcomes that are (not) associated with perceiving racial discrimination in health care. Contrary to prior theorizing, this work also indicates that having a strong working alliance does not attenuate the consequences of perceiving discrimination among Black individuals living with pain. These results highlight the need for system-level interventions to address perceptions of racial mistreatment in health care. PerspectiveThis work has important public health implications by identifying the broad range of outcomes associated with perceived discrimination in health care among Black Americans. Importantly, a strong physician-patient relationship did not buffer Black individuals from the consequences of perceiving discrimination. These findings inform intervention targets to mitigate racial health disparities.

Chronic pain after traumatic brain injury: a collaborative care approach.

Chronic pain is common after traumatic brain injury (TBI), frequently limits daily activities, and is associated with negative outcomes such as decreased community participation. Despite the negative impact of chronic pain, few people with TBI receive effective treatment. This paper describes a collaborative care (CC) intervention, TBI Care, adapted specifically to treat chronic pain in people living with TBI, emphasizing expert clinician input, cognitive behavioral therapy (CBT) techniques, and other non-pharmacological approaches for decreasing pain interference. 79 participants engaged in the CC intervention from two academic medical rehabilitation clinics with weekly assessments of pain intensity, interference, and medication use. Participant feedback on the intervention was gathered by interview with the care manager (CM) at the last treatment session and/or booster session. Provider feedback was gathered by a confidential survey post intervention. Ninety percent of participants received at least 11 of the target 12 sessions with a care manager (CM), the majority occurring over the phone. Participants endorsed an average of 7 pain locations. All participants received pain education, skills in self-monitoring, goal setting/behavioral activation and relaxation training. Pain interference scores (impact on activity and enjoyment), tracked weekly by the CM, significantly decreased across sessions. 89% of participants received recommendations for CBT skills, 65% received referrals for additional treatments targeting pain interference, and 43% received care coordination. 75% of participants reported 6 or more medications/supplements at both the first and last session, with changes recommended primarily for headache treatment. Feedback from participants and providers was positive. TBI Care, a novel patient-centered CC approach, was flexibly delivered, tailored to the needs of those living with TBI and chronic pain, with a high level of participant engagement, and satisfaction among participants and providers. This approach, prioritizing pain self-management strategies and other non-pharmacological approaches, along with optimizing pharmacological treatment, led to significant reductions in self-reported pain interference and intensity during the intervention. Using a CC model in TBI is feasible and successfully improved access to evidence-based treatments for chronic pain as well as outcomes for pain interference and intensity.

Методы оценки исходов в клинических исследованиях у пациентов с АНЦА-ассоциированными васкулитам

Immunosuppressive therapy significantly improved survival of patients with ANCA-associated vasculitides (AAV). However, the adverse effects of therapy, particularly glucocorticosteroids, along with the accumulation of organ damage and a deterioration in the quality of life, have become the leading factors contributing to the disease burden. The development of a core outcome set and assessment tools is a current problem of research methodology to improve their quality and uniformity of data. Disease activity and damage assessed by the Birmingham Vasculitis Activity Score (BVAS v.3) and the Vasculitis Damage Index (VDI), respectively, as well as patient-reported outcomes (PRO) and mortality are approved as the core set domains. The main assessment tools for PRO include the AAV-specific PRO questionnaire (AAV-PRO), the Medical Outcomes Study Short-Form 36 (SF-36 v.2) and three generic Patient-Reported Outcomes Measurement Information System (PROMIS) instruments (fatigue, physical functioning, and pain interference). There are also a number of tools specific for the particular manifestations of the disease, such as glomerulonephritis, asthma or chronic rhinosinusitis.

Race, Ethnicity, and Gender Differences in Patient Reported Well-Being and Cognitive Functioning Within 3 Months of Symptomatic Illness During COVID-19 Pandemic.

Differences in acute COVID-19 associated morbidity based on race, ethnicity, and gender have been well described; however, less is known about differences in subsequent longer term health-related quality of life and well-being. This prospective cohort study included symptomatic adults tested for SARS-CoV-2 who completed baseline and 3-month follow-up surveys. Using the PROMIS-29 tool, a validated measure of health and well-being, we compared outcomes at 3months and change in outcomes from baseline to 3months among groups with different races, ethnicities, and/or sexes. Among 6044 participants, 4113 (3202 COVID +) were included. Among COVID + participants, compared to non-Hispanic White participants, Black participants had better PROMIS T-scores for cognitive function (3.6 [1.1, 6.2]) and fatigue (- 4.3 [- 6.6, - 2.0]) at 3months and experienced more improvement in fatigue over 3months (- 2.7 [- 4.7, - 0.8]). At 3months, compared with males, females had worse PROMIS T-scores for cognitive function (- 4.1 [- 5.6, - 2.6]), physical function (- 2.1 [- 3.1, - 1.0]), social participation (- 2.8 [- 4.2, - 1.5]), anxiety (2.8 [1.5, 4.1]), fatigue (5.1 [3.7, 6.4]), and pain interference (2.0 [0.9, 3.2]). Females experienced less improvement in fatigue over 3months (3.1 [2.0, 4.3]). Transgender/non-binary/other gender participants had worse 3-month scores in all domains except for sleep disturbance and pain interference. Three months after the initial COVID-19 infection, Black participants reported better cognitive function and fatigue, while females and other gender minoritized groups experienced lower well-being. Future studies are necessary to better understand how and why social constructs, specifically race, ethnicity, and gender, influence differences in COVID-19-related health outcomes.

A Randomized Trial Evaluating Acceptance and Commitment Therapy and Smart Phone Care Management Application to Augment Buprenorphine Therapy for Opioid Use and Chronic Pain.

There is high comorbidity of opioid use disorder (OUD) and chronic pain (CP), which is often addressed by prescribing buprenorphine (BUP). While BUP is effective in preventing overdose, it does not address the psychological aspects of OUD and CP comorbidity and treatment retention rates are as low as 50%. The Virtual Opioid use disorder Integrated Chronic Pain Treatment (VOICE) study (NCT05039554) is a novel effectiveness-implementation trial to test a 12-week virtual group Acceptance and Commitment Therapy (ACT) protocol and a care management smartphone application (app; Valera Health) on pain and opioid use in patients with OUD and CP receiving BUP. Using a 2 × 2 factorial design, participants (expected N = 280) are randomized into: ACT, Valera app, ACT + Valera, or Treatment as Usual arm. This study is taking place in the Bronx, NY, a racially/ethnically diverse community that faces numerous socioeconomic stressors and is one of the nation's epicenters of the opioid epidemic. We created a culturally responsive ACT group protocol, and Valera psychoeducational material. Outcome measures include NIH HEAL Common Data Elements and ACT and Valera-specific measures. We are conducting a novel 2 × 2 trial investigating augmenting BUP treatment with ACT and Valera, with the goal that improved mental health and access to care will result in decreased and opioid use and pain interference.

Cannabidiol plus krill oil supplementation improves chronic stifle osteoarthritis in dogs: A double-blind randomized controlled trial

Osteoarthritis (OA) is the most common orthopedic disorder characterized by chronic inflammation and pain in dogs and cats. Cannabis spp. contains cannabidiol (CBD), a substance with pain relief and anti-inflammatory properties in different animals including dogs with OA. The use of CBD supplements has been increasingly intertwining in veterinary medicine. This study aimed to evaluate the clinical efficacy of CBD + krill oil-supplemented biscuit against canine OA. In total, 30 dogs with stifle OA were randomized and divided into the placebo, krill oil, and CBD + krill oil groups. The Canine Brief Pain Inventory questionnaire was used to evaluate the efficacy of each treatment against pain. Stifle temperature was monitored to identify degrees of stifle inflammation. Two and one dogs in the placebo group were excluded from the study due to worsening lameness and increased pain interference score (PIS) and pain severity score (PSS) at days 14 and 28, respectively.The PIS and PSS scores of the krill oil and CBD + krill oil groups gradually and significantly improved after two weeks of treatment. The CBD + krill oil group had better PIS and PSS scores than the placebo and krill oil groups. However, there was no statistically significant difference in the PIS and PSS scores between the krill oil and CBD + krill oil groups. The stifle temperature of the three groups at different periods did not significantly differ. In conclusion, CBD + krill oil supplements are safe against canine OA. CBD can reduce pain and inflammation.

Positive Association between Patients' Perception of Chronic Pain Rehabilitation as a Personally Meaningful Experience and the Flourishing Aspect of Well-Being.

Chronic pain rehabilitation helps to reduce pain and restore valued life roles. Patients may have more positive outcomes when they perceive rehabilitation to be personally meaningful. This study examined associations between self-reported, personally meaningful rehabilitation and well-being. A pilot study was conducted using an online survey of people with chronic pain and experiences of rehabilitation. The PROMIS Pain Interference Short Form 8a and The Flourishing Scale were used to explore well-being. A modified self-report measure, the Meaningfulness in Rehabilitation Scale, was pilot-tested for construct validity and used in the survey. Of the 48 participants (81% female; 19% male), most attended a generalist therapy practice (62%) once per week (33%) or once per fortnight (29%). No statistically significant relationship was found between self-reported meaningfulness in rehabilitation and pain interference or other patient and therapy characteristics (duration of chronic pain category, type of therapy practice, resolution of rehabilitation category, and frequency of appointments). The nonparametric analysis identified a statistically significant moderate positive correlation between self-reported meaningfulness in rehabilitation and the flourishing aspect of well-being. This raises important questions and suggests that patients' perception of rehabilitation as meaningful warrants further research. This pilot study provides valuable guidance to inform a larger investigation.

Associations between smoking history, baseline pain interference and symptom distribution, and physical function at discharge, in individuals seeking care for musculoskeletal pain

ObjectiveStudy of the association between smoking and pain intensity has produced conflicting results; with less focus on pain interference. Different pain constructs could have varying associations with smoking behaviors. This study sought to investigate the association between smoking history and not only pain intensity, but also pain interference, symptom distribution and physical function. MethodsSmoking history (current, past, or none), pain interference (Pain, Enjoyment of Life, and General Activity scale), symptom distribution and physical function scores were extracted from medical records of patients seen in physical therapy for common sites of musculoskeletal pain (lumbar and cervical spine, knee, or hip). Generalized linear models assessed the relationship between smoking history and pain/function. Results833 patients from an integrated healthcare system were included (mean: 57.6 years, SD=16.3; 43 % male). After controlling for several variables, current smokers had significantly higher baseline pain interference scores compared to never and former smokers (beta [B]: 0.65, 95 %CI: 0.13 to 1.18, P=.02). Smoking was not a significant predictor of symptom distribution at baseline [B: 0.17, 95 %CI −0.06 to 0.42, P=.16] or physical function scores at discharge [B: -0.03, 95 %CI: −0.08 to 0.02, P=.25]. ConclusionSmokers experienced a greater impact of pain at baseline. However, symptom distribution at intake and function upon discharge were similar between all smoking groups. These findings suggest smoking cessation and abstinence may be important recommendations to help curb pain interference.

The Association Between Experienced Discrimination and Pain in the REasons for Geographic and Racial Differences in Stroke (REGARDS) Study.

The relationship between experienced discrimination and its effects on pain interference and management among racial disparities is not well explored. This research investigated these associations among Black and White U.S. adults. The analysis involved 9369 Black and White adults in the REasons for Geographic and Racial Differences in Stroke (REGARDS), assessing experiences of discrimination, pain interference (SF-12), and pain treatment, incorporating factors like demographics, comorbidities, and stress. Black participants experiencing moderate discrimination were found to have a 41% increased likelihood of pain interference (aOR 1.41, 95% CI 1.02-1.95), similaritythose facing high levels of discriminationalso showed a 41% increase (aOR 1.41, 95% CI 1.06-1.86) compared to those without such experiences. White individuals reporting moderate discrimination also faced a heightened risk, with a 21% greater chance of pain interference (aOR 1.21, 95% CI 1.01-1.45). Notably, the presence of moderate discrimination among Black participants correlated with a 12% reduced probability of receiving pain treatment (aOR 0.88, 95% CI 0.56-1.37). Furthermore, Black, and White individuals who reported discrimination when seeking employment had a 33% (aOR 0.67, 95% CI 0.45-0.98) and 32% (aOR 0.68, 95% CI 0.48-0.96) lower likelihood, respectively, of receiving treated pain. The study elucidates how discrimination exacerbates pain interference and restricts access to treatment, affecting Black and White individuals differently. These findings underscore an urgent need for strategies to counteract discrimination's negative effects on healthcare outcomes. Addressing these disparities is crucial for advancing health equity and improving the overall quality of care.

Reliability and validity of the Brief Pain Inventory-Short Form in individuals with rotator cuff-related shoulder pain

Purpose To investigate the test–retest reliability and construct validity of the Brief Pain Inventory-Short Form (BPI-SF) in individuals with rotator cuff-related shoulder pain (RCRSP). Methods Sixty-one participants with RCRSP completed the BPI-SF twice with an interval of two to seven days and Shoulder Pain and Disability Index (SPADI) at the initial visit. The BPI-SF pain severity subscale, pain interference subscale, and stand-alone pain severity items were analysed using intraclass correlation coefficients (ICCs) and minimal detectable change at the 95% confidence interval (MDC95). The construct validity of BPI-SF was assessed against SPADI using Pearson’s correlation. Results The BPI-SF pain severity and pain interference subscales presented moderate test–retest reliability (ICC = 0.73, 0.53) and MDC95 were 2.05 and 2.36. All stand-alone BPI-SF pain severity items presented a moderate reliability (ICC = 0.62, 0.70). BPI-SF interference items presented poor to moderate reliability (ICC = 0.39, 0.68). The correlation coefficients between the BPI-SF and SPADI subscales or total scores were large (r = 0.61, 0.75). Conclusions BPI-SF pain severity and pain interference subscales have a moderate reliability in individuals with RCRSP. BPI-SF pain severity and interference subscales showed high construct validity in individuals with RCRSP. MDC95 values are useful metrics for interpreting a true change in BPI-SF scores following interventions in individuals with RCRSP.
