A randomized controlled efficacy trial of mindfulness-based stress reduction compared with an active control group and usual care for fibromyalgia: the EUDAIMON study

Comprehensive Review of Chronic Stress Pathways and the Efficacy of Behavioral Stress Reduction Programs (BSRPs) in Managing Diseases

The connection between chronic psychological stress and the onset of various diseases, including diabetes, HIV, cancer, and cardiovascular conditions, is well documented. This review synthesizes current research on the neurological, immune, hormonal, and genetic pathways through which stress influences disease progression, affecting multiple body systems: nervous, immune, cardiovascular, respiratory, reproductive, musculoskeletal, and integumentary. Central to this review is an evaluation of 16 Behavioral Stress Reduction Programs (BSRPs) across over 200 studies, assessing their effectiveness in mitigating stress-related health outcomes. While our findings suggest that BSRPs have the potential to enhance the effectiveness of medical therapies and reverse disease progression, the variability in study designs, sample sizes, and methodologies raises questions about the generalizability and robustness of these results. Future research should focus on long-term, large-scale studies with rigorous methodologies to validate the effectiveness of BSRPs.

Mindfulness-based stress reduction (MBSR) for fibromyalgia patients: The role of pain cognitions as mechanisms of change

BACKGROUND

Fibromyalgia (FM) is a pain condition characterized by physical and psychological difficulties. This randomized controlled trial aimed to evaluate the effects of a mindfulness-based stress reduction (MBSR) on FM patients and identify the role of two pain cognitions: psychological inflexibility in pain (PIPS) and pain catastrophizing (PCS), as mechanisms of change.

METHODS

95 FM patients (Mean ± SD: 49.18 ± 13.26 years) were randomly assigned to MBSR group therapy (n = 49) or a waitlist (WL) control group (n = 46). An adapted MBSR protocol for FM was employed. A series of measures were taken, covering FM symptoms, depression, perceived stress (PSS), PIPS and PCS. Three measurements were conducted: pre-intervention, post-intervention and 6-months follow up.

RESULTS

Compared to WL controls, the MBSR group showed greater improvements in FM symptoms (F(1,78) = 2.81, p < 0.05), PSS (F(1,78) = 4.38, p < 0.05) and Depression (F(1,78) = 21.12, p < 0.001), with mostly medium effect sizes. Improvements in PSS (F(2,68) = 7.75, p < 0.05) and depression (F(2,68) = 15.68, p < 0.05) remained stable over six months. The effect of MBSR on FM and PSS was mediated by one's reported change in PIPS. The effect of MBSR on depression was mediated by one's reported change in PCS.

CONCLUSIONS

These results reveal the significant therapeutic potential of MBSR for FM patients, due to the emphasis on non-judging and acceptance of negative inner states. Furthermore, this research identified two important pain-related cognitions as mechanisms of change, suggesting that MBSR contributes to cognitive change, which enables the reduction of physical and psychological distress.

Use of patient-reported global assessment measures in clinical trials of chronic pain treatments: ACTTION systematic review and considerations

ABSTRACT

Establishing clinically meaningful changes in pain experiences remains important for clinical trials of chronic pain treatments. Regulatory guidance and pain measurement initiatives have recommended including patient-reported global assessment measures (eg, Patient-Global Impression of Change [PGIC]) to aid interpretation of within-patient differences in domain-specific clinical trial outcomes (eg, pain intensity). The objectives of this systematic review were to determine the frequency of global assessment measures inclusion, types of measures, domains assessed, number and types of response options, and how measures were analyzed. Of 4172 abstracts screened across 6 pain specialty journals, we reviewed 96 clinical trials of chronic pain treatments. Fifty-two (54.2%) studies included a global assessment measure. The PGIC was most common (n = 28; 53.8%), with relatively infrequent use of other measures. The majority of studies that used a global assessment measure (n = 31; 59.6%) assessed change or improvement in an unspecified domain. Others assessed overall condition severity (n = 9; 17.3%), satisfaction (n = 8; 15.4%), or overall health status/recovery (n = 5; 9.6%). The number, range, and type of response options were variable and frequently not reported. Response options and reference periods even differed within the PGIC. Global assessment measures were most commonly analyzed as continuous variables (n = 24; 46.2%) or as dichotomous variables with positive categories combined to calculate the proportion of participants with a positive response to treatment (n = 18; 34.6%). This review highlights the substantial work necessary to clarify measurement and use of patient global assessment in chronic pain trials and provides short- and long-term considerations for measure selection, reporting and analysis, and measure development.

Usefulness of a Multicomponent Group Intervention Program for Fibromyalgia Patients in Primary Care: A Qualitative Study of Health Professionals

OBJECTIVE

To explore the perceptions and experiences of health professionals who participated in a multicomponent program for fibromyalgia (FM) patients based on health education, physical exercise and cognitive-behavioral therapy.

METHODS

In this qualitative, descriptive study that was based on a pragmatic and utilitarian approach, we conducted two focus groups (FGs) with 12 professionals (nurses and general practitioners) from the primary healthcare system of Spain who had been trained as FM experts. A thematic content analysis was carried out.

RESULTS

The findings were organized into four key domains, each with explanatory emerging themes. Overall, the professionals positively valued the program for the knowledge gain it offered, its integrated approach, the group effect and other benefits to patients. Work overload and peers' lack of acknowledgement of the program's value were identified as barriers. A reduction in the amount of content in each session, the creation of quality-of-care indicators and the promotion of the new professional role (FM expert) were proposed.

CONCLUSIONS

The FM experts supported the program and recognized its usefulness. To implement the program within the primary healthcare system, the program needs to be adjusted to accommodate professionals' and patients' reality, and institutional health policies must be improved by providing training on FM to the healthcare community.

Effectiveness of an amygdala and insula retraining program combined with mindfulness training to improve the quality of life in patients with long COVID: a randomized controlled trial protocol

BACKGROUND

There has been growing clinical awareness in recent years of the long-term physical and psychological consequences of the SARS-CoV-2 virus, known as Long COVID. The prevalence of Long COVID is approximately 10% of those infected by the virus. Long COVID is associated with physical and neuropsychological symptoms, including those related to mental health, psychological wellbeing, and cognition. However, research on psychological interventions is still in its early stages, in which means that available results are still limited. The main objective of this study is to evaluate the effects of a program based on amygdala and insula retraining (AIR) combined with mindfulness training (AIR + Mindfulness) on the improvement of quality of life, psychological well-being, and cognition in patients with Long COVID.

METHODS

This study protocol presents a single-blind randomized controlled trial (RCT) that encompasses baseline, post-treatment, and six-month follow-up assessment time points. A total of 100 patients diagnosed with Long COVID by the Spanish National Health Service will be randomly assigned to either AIR + Mindfulness (n = 50) or relaxation intervention (n = 50), the latter as a control group. The primary outcome will be quality of life assessed using the Short Form-36 Health Survey (SF-36). Additional outcomes such as fatigue, pain, anxiety, memory, and sleep quality will also be evaluated. Mixed effects regression models will be used to estimate the effectiveness of the program, and effect size calculations will be made.

DISCUSSION

Long COVID syndrome is a clinical condition characterized by the persistence of symptoms for at least 12 weeks after the onset of COVID-19 that significantly affects people's quality of life. This will be the first RCT conducted in Spain to apply a psychotherapy program for the management of symptoms derived from Long COVID. Positive results from this RCT may have a significant impact on the clinical context by confirming the beneficial effect of the intervention program being evaluated on improving the symptoms of Long COVID syndrome and aiding the development of better action strategies for these patients.

Beyond the Pain: A Systematic Narrative Review of the Latest Advancements in Fibromyalgia Treatment

Fibromyalgia is a complex chronic pain disorder that significantly impacts the quality of life of affected individuals. The etiology of fibromyalgia remains elusive, necessitating effective treatment options. This review aims to provide an overview of current treatment options for fibromyalgia and highlight recent updates in managing the condition. The methodology employed in this systematic review comprised the following key steps. We conducted a comprehensive search across various databases to identify pertinent studies published between 2000 and 2023. Inclusion criteria were defined to specifically target studies involving adult individuals diagnosed with fibromyalgia, with a focus on both pharmacological and non-pharmacological interventions for managing the condition. The review encompassed a range of study types, including randomized controlled trials, observational studies, and systematic reviews. To ensure the quality of the selected studies, we employed appropriate assessment tools, and data extraction and synthesis adhered to established guidelines. This rigorous approach allowed for a robust analysis of the literature on fibromyalgia management. In the course of our review, it became evident that a spectrum of treatment approaches holds significant promise in the management of fibromyalgia. Specifically, pharmacological interventions, including selective serotonin-norepinephrine reuptake inhibitors, anticonvulsants, cannabinoids, tropisetron, and sodium oxybate, have exhibited substantial potential in alleviating fibromyalgia symptoms. Concurrently, non-pharmacological strategies, such as cognitive-behavioral therapy, exercise regimens, and complementary and alternative therapies, have yielded positive outcomes in improving the condition's management. Recent developments in the field have introduced innovative pharmacological agents like milnacipran and pregabalin, in addition to non-pharmacological interventions like mindfulness-based stress reduction and aquatic exercise, expanding the array of options available to enhance fibromyalgia care and alleviating patient symptoms. Fibromyalgia necessitates a multidisciplinary approach to treatment, encompassing both pharmacological and non-pharmacological interventions. Recent updates in fibromyalgia management offer additional options to alleviate symptoms and improve the quality of life for individuals with fibromyalgia. Healthcare professionals should remain informed about these advancements to provide evidence-based care, addressing the complex symptoms associated with fibromyalgia and enhancing patient outcomes.

Covariate Adjustment in Chronic Pain Trials: An Oft-Missed Opportunity

Self-reported pain intensity, frequently used as an outcome in randomized clinical trials (RCTs) of chronic pain, is often highly variable and could be associated with multiple baseline factors. Thus, the assay sensitivity of pain trials (ie, the ability of the trial to detect a true treatment effect) could be improved by including prespecified baseline factors in the primary statistical model. The objective of this focus article was to characterize the baseline factors included in statistical analyses of chronic pain RCTs. Seventy-three RCTs published between 2016 and 2021 that investigated interventions for chronic pain were included. The majority of trials identified a single primary analysis (72.6%; n = 53). Of these, 60.4% (n = 32) included one or more covariates in the primary statistical model, most commonly baseline value of the primary outcome, study site, sex, and age. Only one of the trials reported information regarding associations between covariates and outcomes (ie, information that could inform prioritization of covariates for prespecification in future analyses). These findings demonstrate inconsistent use of covariates in the statistical models in chronic pain clinical trials. Prespecified adjustments for baseline covariates that could increase precision and assay sensitivity should be considered in future clinical trials of chronic pain treatments. PERSPECTIVE: This review demonstrates inconsistent inclusion and potential underutilization of covariate adjustment in analyses of chronic pain RCTs. This article highlights areas for possible improvement in design and reporting related to covariate adjustment to improve efficiency in future RCTs.

Efficacy of Videoconference Group Acceptance and Commitment Therapy (ACT) and Behavioral Activation Therapy for Depression (BATD) for Chronic Low Back Pain (CLBP) Plus Comorbid Depressive Symptoms: A Randomized Controlled Trial (IMPACT Study)

This study examined the efficacy of adding a remote, synchronous, group, videoconference-based form of acceptance and commitment therapy (ACT) or behavioral activation therapy for depression (BATD) to treatment-as-usual (TAU) in 234 patients with chronic low back pain (CLBP) plus comorbid depressive symptoms. Participants were randomly assigned to ACT, BATD, or TAU. Compared to TAU, ACT produced a significant reduction in pain interference at posttreatment (d = .64) and at follow-up (d = .73). BATD was only superior to TAU at follow-up (d = .66). A significant reduction in pain catastrophizing was reported by patients assigned to ACT and BATD at posttreatment (d = .45 and d = .59, respectively) and at follow-up (d = .59, in both) compared to TAU. Stress was significantly reduced at posttreatment by ACT in comparison to TAU (d = .69). No significant between-group differences were found in depressive or anxiety symptoms. Clinically relevant number needed to treat (NNT) values for reduction in pain interference were obtained at posttreatment (ACT vs TAU = 4) and at follow-up (ACT vs TAU = 3; BATD vs TAU = 5). In both active therapies, improvements in pain interference at follow-up were significantly related to improvements at posttreatment in psychological flexibility. These findings suggest that new forms of cognitive-behavioral therapy are clinically useful in improving pain interference and pain catastrophizing. Further research on evidence-based change processes is required to understand the therapeutic needs of patients with chronic pain and comorbid conditions. TRIAL NUMBER: NCT04140838. PERSPECTIVE: Group videoconference-based ACT and BATD showed greater efficacy than TAU for reducing pain interference and pain catastrophizing in patients with CLBP plus clinically relevant depression. Psychological flexibility appeared to be the main contributor to treatment effects for both ACT and BATD.

Are OMERACT recommendations followed in clinical trials on fibromyalgia? A systematic review of patient-reported outcomes and their measures

PURPOSE

Patient-Reported Outcomes (PROs) and its measures (PROMs) are key to outcome assessment in Fibromyalgia (FM) trials. The aim of this review was to investigate which domains and instruments were assessed in recent FM trials and to compare them to recommendations by the Outcome Measures in Rheumatology (OMERACT) initiative. In addition, we investigated the overlap with a generic health assessment approach, i.e. eight domains suggested by the Patient-Reported Outcome Measurement Information System® (PROMIS®).

METHODS

In compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic literature search in scientific databases including PubMed, PsycInfo, and Embase was conducted to identify studies that assessed at least two dimensions of health-related quality of life (HRQoL) from 2015 to June 2022. Non-randomized and randomized controlled trials were included in the analysis. We extracted PROs and PROMs used in each study.

RESULTS

From 1845 identified records, 107 records out of 105 studies met the inclusion criteria. Studies investigated 50 PROs using 126 different PROMs. Most frequently assessed domains were pain, depression, fatigue, and anxiety (> 95% of the studies). The disease-specific FIQ was the most frequently applied PROM (82%). Overall, only 9% of the studies covered all domains deemed mandatory by OMERACT. Very few studies covered all eight generic health domains suggested by PROMIS.

CONCLUSION

The majority of trials covered most OMERACT domains or generic PROMIS health domains. There was, however, great variability in the instruments used to assess the domains, which points at a limited degree of standardization in the field.

Neurophysiological and Psychosocial Mechanisms of Fibromyalgia: A Comprehensive Review and Call for An Integrative Model

Research into the neurobiological and psychosocial mechanisms involved in fibromyalgia has progressed remarkably in recent years. Despite this, current accounts of fibromyalgia fail to capture the complex, dynamic, and mutual crosstalk between neurophysiological and psychosocial domains. We conducted a comprehensive review of the existing literature in order to: a) synthesize current knowledge on fibromyalgia; b) explore and highlight multi-level links and pathways between different systems; and c) build bridges connecting disparate perspectives. An extensive panel of international experts in neurophysiological and psychosocial aspects of fibromyalgia discussed the collected evidence and progressively refined and conceptualized its interpretation. This work constitutes an essential step towards the development of a model capable of integrating the main factors implicated in fibromyalgia into a single, unified construct which appears indispensable to foster the understanding, assessment, and intervention for fibromyalgia.

A Systematic Review of the Adherence to Home-Practice Meditation Exercises in Patients with Chronic Pain

Mindfulness-, compassion-, and acceptance-based (i.e., "third wave") psychotherapies are effective for treating chronic pain conditions. Many of these programs require that patients engage in the systematic home practice of meditation experiences so they can develop meditation skills. This systematic review aimed at evaluating the frequency, duration, and effects of home practice in patients with chronic pain undergoing a "third wave" psychotherapy. A comprehensive database search for quantitative studies was conducted in PubMed, Embase, and Web of Sciences Core Collection; 31 studies fulfilled the inclusion criteria. The reviewed studies tended to indicate a pattern of moderately frequent practice (around four days/week), with very high variability in terms of time invested; most studies observed significant associations between the amount of practice and positive health outcomes. Mindfulness-Based Stress Reduction and Mindfulness-Based Cognitive Therapy were the most common interventions and presented low levels of adherence to home practice (39.6% of the recommended time). Some studies were conducted on samples of adolescents, who practiced very few minutes, and a few tested eHealth interventions with heterogeneous adherence levels. In conclusion, some adaptations may be required so that patients with chronic pain can engage more easily and, thus, effectively in home meditation practices.

"INTEGRO INTEGRated Psychotherapeutic InterventiOn" on the Management of Chronic Pain in Patients with Fibromyalgia: The Role of the Therapeutic Relationship

Fibromyalgia (FM) is a chronic disease characterized by a heterogeneous set of physical and psychological conditions. The chronic experience of disability felt by patients and the impact on quality of life (QoL) of the disease may worsen the cognitive reappraisal ability and contribute to maintaining an altered pain modulation mechanism. This paper presents the study protocol of an INTEGRated psychotherapeutic interventiOn on the management of chronic pain in patients with fibromyalgia (INTEGRO). The aim of the study is to investigate the efficacy of an integrated psychotherapeutic intervention focused on pain management on QoL and pain perception, in a pilot sample of 45 FM patients with idiopathic chronic pain. The contribution of perceived therapeutic relationship (alliance) and physiological attunement, in both the patient and therapist, will be considered as possible mediators of intervention efficacy. Attachment dimensions, traumatic experiences, difficulties in emotion regulation, mindfulness attitude and psychophysiological profile will also be considered as covariates. The objectives are to evaluate longitudinally if patients will experience an increase in QoL perception (primary endpoint), pain-managing self-efficacy and emotion-regulation abilities as well as a reduction in pain intensity (secondary endpoints), considering the mediating role of perceived therapeutic alliance and physiological attunement in both the patient and therapist.

Systemic Sclerosis Patients Experiencing Mindfulness-Based Stress Reduction Program: The Beneficial Effect on Their Psychological Status and Quality of Life

Psychological concerns in Systemic Sclerosis (SSc) patients represent an important issue and should be addressed through non-pharmacological treatments. Thus, the aim of the present study was to assess the effects of the Mindfulness-Based Stress Reduction (MBSR) program on psychological variables and the perspectives and experiences of patients with an SSc diagnosis. Notably, 32 SSc patients were enrolled and assigned to either the intervention (MBSR) group or the waitlist group. Inclusion criteria were (i) age ≥ 18 years, SSc diagnosis according to EULAR/ACR diagnostic criteria and informed consent. Exclusion criteria were previous participation in any Mind-Body Therapy or psychiatric diagnosis. Quantitative and qualitative outcomes were investigated through clinometric questionnaires and individual interviews. MBSR did not significantly impact outcomes such as physical functionality, anxiety, hopelessness, depression, physical health status, perceived stress, mindfulness and mental health status. For the anger evaluation, statistically significant differences are found for both controlling and expressing anger, indicating that the MBSR program had a favorable impact. As for qualitative results, more awareness of daily activities, stress reduction in terms of recognizing the causes and implementing self-strategies to prevent them, adherence to therapy, and recognition of the effect of medication on their bodies were reported. In conclusion, it is important to highlight the absence of negative or side effects of the MBSR program and the positive impact on patients' experience and perspective; thus, we suggest this approach should be taken into account for SSc patients.

Efficacy of mindfulness- and acceptance-based cognitive-behavioral therapies for bodily distress in adults: a meta-analysis

Objective

Bodily distress, i.e., somatoform disorders and associated functional somatic syndromes, is highly prevalent, often persistent and highly disabling. It has been proposed that "third wave" therapies may be beneficial variants of cognitive behavioral treatments. However, evidence on their efficacy is scarce. This meta-analysis examines the efficacy of "third wave" psychotherapies (mindfulness-based cognitive therapy [MBCT], mindfulness-based stress reduction [MBSR], and acceptance and commitment therapy [ACT]) in adults with bodily distress.

Method

We included randomized controlled trials (RCTs) treating adults with bodily distress using MBCT, MBSR, and ACT compared to inactive and non-specific control groups. A random effects model was used. The primary outcome was somatic symptom severity. Secondary outcomes were degrees of depression and of anxiety, health anxiety, perceived health status, mindfulness, psychological inflexibility, and pain acceptance.

Results

Sixteen RCTs with 1,288 participants were included in the analysis (k = 4 MBCT, k = 7 MBSR, k = 5 ACT; k = 7 fibromyalgia, k = 5 irritable bowel syndrome, k = 1 chronic fatigue syndrome, k = 2 bodily distress, k = 1 medically unexplained symptoms). However, not all studies provided data for each of the relevant outcomes. The analyses revealed that "third wave" therapies were more effective than control conditions in reducing somatic symptom severity (k = 15, n = 1,100, g = -0.51, 95%CI -0.69; -0.32). Heterogeneity was moderate (I ² = 52.8%, 95%CI 15.1 to 73.8). Effects for secondary outcomes were small to moderate with varying degrees of heterogeneity. We did not find differences between the different therapy approaches (mindfulness- vs. acceptance-based therapies); neither therapy dosis (i.e., total duration of therapy sessions) nor number of sessions were significant moderators of efficacy.

Conclusions

The therapies addressing mindfulness and acceptance proved to be more effective than control conditions. Hence, they are promising treatment approaches for bodily distress. However, there is still need for research on which patient groups may benefit from these psychological approaches.

Effectiveness, cost-utility and physiological underpinnings of the FIBROWALK multicomponent therapy in online and outdoor format in individuals with fibromyalgia: Study protocol of a randomized, controlled trial (On&Out study)

Introduction: The On&amp;Out study is aimed at assessing the effectiveness, cost-utility and physiological underpinnings of the FIBROWALK multicomponent intervention conducted in two different settings: online (FIBRO-On) or outdoors (FIBRO-Out). Both interventions have proved to be efficacious in the short-term but there is no study assessing their comparative effectiveness nor their long-term effects. For the first time, this study will also evaluate the cost-utility (6-month time-horizon) and the effects on immune-inflammatory biomarkers and Brain-Derived Neurotrophic Factor (BDNF) levels of both interventions. The objectives of this 6-month, randomized, controlled trial (RCT) are 1) to examine the effectiveness and cost-utility of adding FIBRO-On or FIBRO-Out to Treatment-As-Usual (TAU) for individuals with fibromyalgia (FM); 2) to identify pre–post differences in blood biomarker levels in the three study arms and 3) to analyze the role of process variables as mediators of 6-month follow-up clinical outcomes.

Methods and analysis: Participants will be 225 individuals with FM recruited at Vall d’Hebron University Hospital (Barcelona, Spain), randomly allocated to one of the three study arms: TAU vs. TAU + FIBRO-On vs. TAU + FIBRO-Out. A comprehensive assessment to collect functional impairment, pain, fatigue, depressive and anxiety symptoms, perceived stress, central sensitization, physical function, sleep quality, perceived cognitive dysfunction, kinesiophobia, pain catastrophizing, psychological inflexibility in pain and pain knowledge will be conducted pre-intervention, at 6 weeks, post-intervention (12 weeks), and at 6-month follow-up. Changes in immune-inflammatory biomarkers [i.e., IL-6, CXCL8, IL-17A, IL-4, IL-10, and high-sensitivity C-reactive protein (hs-CRP)] and Brain-Derived Neurotrophic Factor will be evaluated in 40 participants in each treatment arm (total n = 120) at pre- and post-treatment. Quality of life and direct and indirect costs will be evaluated at baseline and at 6-month follow-up. Linear mixed-effects regression models using restricted maximum likelihood, mediational models and a full economic evaluation applying bootstrapping techniques, acceptability curves and sensitivity analyses will be computed.

Ethics and dissemination: This study has been approved by the Ethics Committee of the Vall d’Hebron Institute of Research. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media and various community engagement activities. Trial registration number NCT05377567 (clinicaltrials.gov).

Mindfulness as a Symptom Management Strategy for Fibromyalgia: An Integrative Review

Introduction: Mindfulness Meditation is a complementary and alternative medicine (CAM) modality growing in popularity. Currently, mindfulness is under-studied regarding efficacy; however, it offers a potentially accessible way to contribute to symptom management in chronic pain conditions. The purpose of this integrative review was to examine the literature for the use of mindfulness as symptom management strategy for persons diagnosed with the chronic pain condition, fibromyalgia. Methods: Six scientific databases were searched, using various keywords. Inclusion criteria were: (a) fibromyalgia, (b) English language, (c) experimental research designs; (d) adults age ≥ 18 years, and (e) mindfulness. Results: Seven studies were reviewed. Most interventions were completed over several months in the form of multiple group sessions lasting several hours each. Evaluations of effectiveness varied by study, but variables most commonly demonstrating improvement from mindfulness were anxiety, depression, sleep-related symptoms, coping and perceived stress. Mechanisms by which these outcomes may have been mediated included increases in self-compassion and psychological flexibility. Discussion: There is insufficient evidence to recommend mindfulness as an effective way to manage all fibromyalgia symptoms; however, promise lies in its usefulness addressing mood- and sleep-related symptoms. We suggest that further, more rigorous, research is warranted.

Effectiveness of two video-based multicomponent treatments for fibromyalgia: The added value of cognitive restructuring and mindfulness in a three-arm randomised controlled trial

BACKGROUND/OBJECTIVES

The aim of this study was to examine the effectiveness of two video-based multicomponent programs (FIBROWALK) and the Multicomponent Physiotherapy Program (MPP) for patients with fibromyalgia (FM) compared to treatment-as-usual (TAU) only. We posit that FIBROWALK, due to inclusion of specific psychological ingredients (cognitive restructuring and mindfulness), can produce additional clinical benefits when compared to TAU or MPP alone.

METHODS

A total of 330 patients with FM were recruited and randomly allocated (1:1:1) to TAU only, TAU + FIBROWALK, or TAU + MPP. FIBROWALK and MPP consisted of weekly videos on pain neuroscience education, therapeutic exercise and self-management patient education, but only the FIBROWALK intervention provided cognitive restructuring and mindfulness. Both programs were structurally equivalent. Between-group differences in functional impairment, pain, kinesiophobia, anxious-depressive symptoms and physical functioning were evaluated at post-treatment following Intention-To-Treat and complete-case approaches.

RESULTS

Compared to TAU only, individuals in the FIBROWALK arm showed larger improvements in all clinical outcomes; similarly, participants in the MPP program also showed greater improvements in functional impairment, perceived pain, kinesiophobia, depressive symptoms compared to TAU only. The FIBROWALK intervention showed superior effects in improving pain, anxiety and depressive symptoms and physical functioning compared to MPP.

CONCLUSIONS

This RCT supports the short-term effectiveness of the video-based multicomponent programs FIBROWALK and MPP for FM and provides evidence that cognitive-behavioural and mindfulness-based techniques can be clinically useful in the context of physiotherapeutic multicomponent treatment programs.

Efficacy of nonpharmacological interventions for individual features of fibromyalgia: a systematic review and meta-analysis of randomised controlled trials

ABSTRACT

Fibromyalgia is a highly heterogeneous condition, but the most common symptoms are widespread pain, fatigue, poor sleep, and low mood. Nonpharmacological interventions are recommended as first-line treatment of fibromyalgia. However which interventions are effective for the different symptoms is not well understood. The objective of this study was to assess the efficacy of nonpharmacological interventions on symptoms and disease-specific quality of life. Seven databases were searched from their inception until June 1, 2020. Randomised controlled trials comparing any nonpharmacological intervention to usual care, waiting list, or placebo in people with fibromyalgia aged >16 years were included without language restriction. Fibromyalgia Impact Questionnaire (FIQ) was the primary outcome measure. Standardised mean difference and 95% confidence interval were calculated using random effects model. The risk of bias was evaluated using the modified Cochrane tool. Of the 16,251 studies identified, 167 randomised controlled trials (n = 11,012) assessing 22 nonpharmacological interventions were included. Exercise, psychological treatments, multidisciplinary modality, balneotherapy, and massage improved FIQ. Subgroup analysis of different exercise interventions found that all forms of exercise improved pain (effect size [ES] -0.72 to -0.96) and depression (ES -0.35 to -1.22) except for flexibility exercise. Mind-body and strengthening exercises improved fatigue (ES -0.77 to -1.00), whereas aerobic and strengthening exercises improved sleep (ES -0.74 to -1.33). Psychological treatments including cognitive behavioural therapy and mindfulness improved FIQ, pain, sleep, and depression (ES -0.35 to -0.55) but not fatigue. The findings of this study suggest that nonpharmacological interventions for fibromyalgia should be individualised according to the predominant symptom.

Research in Mindfulness Interventions for Patients With Fibromyalgia: A Critical Review

Fibromyalgia is one of the most common causes of widespread chronic pain. It has a huge impact on the quality of life, namely because it appears earlier in life than most of the chronic pain conditions. Furthermore, emotional-cognitive distress factors, such as depression and anxiety, are a common feature in patients with fibromyalgia. The neurobiological mechanisms underlying fibromyalgia remain mostly unknown. Among non-pharmacological treatments, cognitive-behavioral therapy has been used during the last decade, namely with the enrolment of patients in programs of mindfulness-based stress reduction (MBSR) and in mindfulness-based interventions (MBI). We critically analyzed the literature to search for scientific evidence for the use of MBI in fibromyalgia. The studies were evaluated as to several outcomes of fibromyalgia improvement along with aspects of the study design which are currently considered relevant for research in mindfulness. We conclude that despite the sparsity of well-structured longitudinal studies, there are some promising results showing that the MBI are effective in reducing the negative aspects of the disease. Future design of studies using MBI in fibromyalgia management should be critically discussed. The importance of active controls, evaluation of sustained effects along with investigation of the subserving neurobiological mechanisms and detailed reports of possible adverse effects should be considered.

Attachment-Based Compassion Therapy for Reducing Anxiety and Depression in Fibromyalgia

Fibromyalgia patients often experience anxiety and depressive symptoms; however, validated interventions show only limited efficacy. This pilot study analyzed the effects of a 16-session version of attachment-based compassion therapy (ABCT-16) for improving anxiety and depressive symptomatology, as well as self-compassion and decentering, in 11 fibromyalgia patients. Scales were assessed at four time points: baseline, after sessions 8 and 16, and 3.5 months after the completion of the program. Significant improvements were found in all outcomes after the program, and most remained significant in the follow-up assessment. Our preliminary results suggest that ABCT-16 can be effective for improving anxiety and depressive symptomatology in fibromyalgia patients. Nonetheless, further studies with larger samples and control groups are necessary to confirm these results.

Emotional Stress Relief Mechanism of English Translation Practitioners Based on Role Cognition

The emotional stress of English translation practitioners is an important research content of psychological organization counseling behavior. Based on the theory of role cognition, this paper adopts the perspective of emotional stress experience, integrates the construction theory and the self-determination theory, and builds an emotional stress relief mechanism for English translation practitioners. On the basis of sorting out psychological capital, emotional commitment, and behavioral variables of organizational practitioners, the article summarizes the concept, dimension, measurement, and causes and effects of variables and solves the problem of quantitative analysis of emotional stress. In the simulation process, the role cognitive variables and local cognitive variables are extracted separately using the dual-branch mitigation mechanism structure to enhance the diversity of the extracted cognitive variables; in the local branch, a loss function of emotional stress overlapping partial penalty mechanism is constructed. This mechanism is used to select a suitable destination sink node for the sensor nodes around the sink node with heavy load to transmit data and effectively relieve the data collection pressure of the original sink node. The experimental results show that by using role cognitive variables and local cognitive variables in the training of classification loss and triple loss, respectively, the mitigation mechanism can mine subtle and significant cognitive variables from the local area and finally integrate role cognitive cognition. The accuracy rate of obtaining 297 questionnaires reached 91.4%, which effectively promoted the mechanism research of emotional stress on the behavior of English translation practitioners.

How do psychologically based interventions for chronic musculoskeletal pain work? A systematic review and meta-analysis of specific moderators and mediators of treatment

Psychologically based interventions aim to improve pain-related functioning by targeting pain-related fears, cognitions and behaviors. Mediation and moderation analyses permit further examination of the effect of treatment on an outcome. This systematic review and meta-analysis aims to synthetize the evidence of specific mediators and moderators (i.e., treatment targets) of psychologically based treatment effects on pain and disability. A total of 28 mediation and 11 moderation analyses were included. Thirteen mediation studies were included in a meta-analysis, and the rest was narratively synthetized. Reductions in pain-related fear (indirect effect [IE]: -0.07; 95% confidence interval [CI]: -0.11, -0.04) and catastrophizing (IE: -0.07; 95%CI: -0.14, -0.00), as well as increases in self-efficacy (IE: -0.07; 95%CI: -0.11, -0.04), mediated effects of cognitive behavioral therapy on disability but not on pain intensity, when compared to control treatments. Enhancing pain acceptance (IE: -0.17; 95%CI: -0.31, -0.03) and psychological flexibility (IE: -0.30; 95%CI: -0.41, -0.18) mediated acceptance and commitment therapy effects on disability. The narrative synthesis showed conflicting evidence, which did not support a robust moderated effect for any of the examined constructs. Overall, the methodological quality regarding mediation was low, and some key pitfalls are highlighted alongside recommendations to provide a platform for future research.

Management of Chronic Multisymptom Illness: Synopsis of the 2021 US Department of Veterans Affairs and US Department of Defense Clinical Practice Guideline

In 2019, senior leaders within the US Department of Veterans Affairs and the US Department of Defense commissioned the update of a clinical practice guideline for managing chronic multisymptom illness. Clinical experts were assembled across both agencies to systematically review evidence and to develop treatment recommendations based on that evidence. This effort resulted in the development of 29 evidence-based recommendations for providing care for individuals with chronic multisymptom illness.

Effectiveness of multicomponent treatment in patients with fibromyalgia: protocol for a systematic review and meta-analysis

BACKGROUND

The purpose of this protocol is to provide a new systematic review with meta-analysis using the current methodology to compare the effectiveness of multicomponent treatment versus other interventions for patients with fibromyalgia.

METHODS

This protocol conforms to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) and the recommendations of the Cochrane Collaboration Handbook. An electronic search will be conducted in MEDLINE, EMBASE, Web of Science, Cochrane CENTRAL, LILACS, CINAHL, and PEDro, from inception until April 2022. There will be no language restrictions. The Cochrane Collaboration tool for assessing the risk of bias (RoB2) will be used. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) scale will be used to evaluate the strength of the evidence. The Hartung-Knapp-Sidik-Jonkman random effects or Mantel-Haenszel fixed effects methods will be used, depending on the heterogeneity, to compute a pooled estimate of the mean difference (MD) or standardized mean difference (SMD) and respective 95% confidence intervals for clinical outcomes.

DISCUSSION

This systematic review will synthesize evidence on the effectiveness of multicomponent treatment in patients with fibromyalgia and could add important evidence in the treatment of FM to improve clinical practice and decision-making/actions in this field. This new systematic review will try to show the effects of multicomponent treatment by type (endurance, resistance, stretching, or mind-body exercises [pilates or taichi]) and intensity (light, moderate, moderate-to-vigorous, vigorous) of exercise in patients with FM. The results will be disseminated by publication in a peer-reviewed journal. Ethics approval will not be needed because the data used for this systematic review will be obtained from individual trials and there will be no concerns about privacy. However, if we identify ethical issues during the development of the systematic review, these findings will be reported in the discussion of the study.

Differential Brain Perfusion Changes Following Two Mind–Body Interventions for Fibromyalgia Patients: an Arterial Spin Labelling fMRI Study

Objectives

Further mechanistic insight on mind–body techniques for fibromyalgia (FMS) is needed. Arterial spin labelling (ASL) imaging can capture changes in regional cerebral blood flow (rCBF) that relate to spontaneous pain.

Methods

We recruited FMS patients undergoing either mindfulness-based stress reduction training (MBSR, n = 14) or a psychoeducational programme (FibroQoL, n = 18), and a control FMS group with no add-on treatment (n = 14). We acquired whole-brain rCBF maps and self-report measures at baseline and following treatment and explored interaction effects in brain perfusion between the treatment group and session with a focus on the amygdala, the insula and the anterior cingulate cortex (ACC).

Results

We identified a significant interaction effect in the amygdala, which corresponded with rCBF decreases following FibroQoL specifically. At baseline, rCBF in the amygdala for the FibroQoL group correlated with pain catastrophizing and anxiety scores, but not after treatment, suggesting a decoupling between activity in the amygdala and negative emotional symptoms of FMS as a consequence of treatment. Baseline rCBF correlated positively with pain symptoms in the ACC and the anterior insula across all patients; moreover, the correlation between rCBF changes post intervention in the insula and pain improvement was negative for both treatments and significantly different from the control group. We suggest that there is disruption of the typical relationship between clinical pain and activity as a product of these two nonpharmacological therapies.

Conclusions

We have demonstrated that different mind-to-body treatments correspond to differential changes in clinical symptoms and brain activity patterns, which encourages future research investigating predictors of treatment response.

A Functional Connectivity Study to Investigate the Role of the Right Anterior Insula in Modulating Emotional Dysfunction in Borderline Personality Disorder

OBJECTIVE

Previous imaging studies in patients with borderline personality disorder (BPD) have detected functional brain dysfunctions. Mindfulness training may improve the symptoms of BPD, although the neural mechanisms involved remain poorly understood. This study had several key aims: a) to investigate the role of right anterior insula (rAI) functional connectivity in modulating baseline emotional status in BPD, b) to compare differences in connectivity changes after mindfulness training versus interpersonal effectiveness intervention, and c) to explore the correlation between longitudinal changes in imaging data and clinical indicators.

METHODS

Thirty-eight patients with BPD underwent resting-state functional magnetic resonance imaging. Participants completed self-report clinical scales and participated in a dialectical-behavioral therapy (mindfulness versus interpersonal effectiveness modules). Changes in clinical and imaging variables were evaluated longitudinally after completion of the first 10-week sessions of psychotherapeutic intervention.

RESULTS

At baseline, the rAI was strongly connected with the other salience network nodes and anticorrelated with most core nodes of the default mode network (p < .05, corrected). The functional connectivity of the rAI correlated with emotional dysregulation and deficits in mindfulness capacities (p < .05, corrected). After completion of psychotherapeutic intervention, both groups (mindfulness and interpersonal effectiveness) showed divergent posttherapy functional connectivity changes, which were in turn associated with the clinical response.

CONCLUSIONS

The functional connectivity of the rAI seems to play an important role in emotion dysregulation and deficits in mindfulness capacities in individuals with BPD. Psychotherapy seems to modulate this functional connectivity, leading to beneficial changes in clinical variables.

Pathophysiology and Clinical Implications of Cognitive Dysfunction in Fibromyalgia

Cognitive dysfunction is a complaint of many patients diagnosed with fibromyalgia. Although the main symptoms of the disease are fatigue, widespread musculoskeletal pain, poor sleep quality, and tenderness points, the cognitive symptoms can be more distressing than the pain itself, and negatively affect their lives; however, many healthcare professionals underestimate these cognitive complaints and it is still one of the least researched topics. Proper management of these symptoms at an early stage may have a great impact to improve the mental health, physical function, and overall health of these patients. Hence, this traditional review aimed to look at the previous body of literature in PubMed in the past five years to address the pathophysiology of the cognitive dysfunction in fibromyalgia patients, to find the risk factors of cognitive dysfunction in these patients, to discover the recent modalities for treatment, and to figure out the clinical implications and recent recommendations by researchers on screening, diagnosis, and management of fibromyalgia and its cognitive dysfunction symptoms.

This review has shown the various mechanisms of cognitive dysfunction. Some mechanisms are related to disease symptomologies, such as excessive pain perception, and others are related to hormonal and metabolite changes in the brain. Tobacco smoking and high body mass index showed an inverse impact on cognitive dysfunction and quality of life in fibromyalgia. Other risk factors and clinical implications were discussed in detail.

Effectiveness of a Multicomponent Treatment Based on Pain Neuroscience Education, Therapeutic Exercise, Cognitive Behavioral Therapy, and Mindfulness in Patients With Fibromyalgia (FIBROWALK Study): A Randomized Controlled Trial

OBJECTIVE

The purpose of this study was to evaluate the effectiveness of a 12-week multicomponent treatment based on pain neuroscience education, therapeutic exercise, cognitive behavioral therapy, and mindfulness-in addition to treatment as usual-compared with treatment as usual only in patients with fibromyalgia.

METHODS

This randomized controlled trial involved a total of 272 patients who were randomly assigned to either multicomponent treatment (n = 135) or treatment as usual (n = 137). The multicomponent treatment (2-hour weekly sessions) was delivered in groups of 20 participants. Treatment as usual was mainly based on pharmacological treatment according to the predominant symptoms. Data on functional impairment using the Revised Fibromyalgia Impact Questionnaire as the primary outcome were collected as were data for pain, fatigue, kinesiophobia, physical function, anxiety, and depressive symptoms (secondary outcomes) at baseline, 12 weeks, and, for the multicomponent group only, 6 and 9 months. An intention-to-treat approach was used to analyze between-group differences. Baseline differences between responders (>20% Revised Fibromyalgia Impact Questionnaire reduction) and nonresponders also were analyzed, and the number needed to treat was computed.

RESULTS

At posttreatment, significant between-group differences with a large effect size (Cohen d > 0.80) in favor of the multicomponent treatment were found in functional impairment, pain, kinesiophobia, and physical function, whereas differences with a moderate size effect (Cohen d > 0.50 and <0.80) were found in fatigue, anxiety, and depressive symptoms. Nonresponders scored higher on depressive symptoms than responders at baseline. The number needed to treat was 2 (95% CI = 1.7-2.3).

CONCLUSION

Compared with usual care, there was evidence of short-term (up to 3 months) positive effects of the multicomponent treatment for fibromyalgia. Some methodological shortcomings (eg, absence of follow-up in the control group and monitoring of treatment adherence, potential research allegiance) preclude robust conclusions regarding the proposed multicomponent program.

IMPACT

Despite some methodological shortcomings in the design of this study, the multicomponent therapy FIBROWALK can be considered a novel and effective treatment for patients with fibromyalgia. Physical therapists should detect patients with clinically relevant depression levels prior to treatment because depression can buffer treatment effects.

LAY SUMMARY

Fibromyalgia is prevalent and can be expensive to treat. This multicomponent treatment could significantly improve the core symptoms of fibromyalgia compared with usual treatment.

Effectiveness of mindfulness-based stress reduction and attachment-based compassion therapy for the treatment of depressive, anxious, and adjustment disorders in mental health settings: A randomized controlled trial

OBJECTIVES

To study the effectiveness of attachment-based compassion therapy (ABCT) for reducing affective distress in a sample of outpatients with depressive, anxiety, or adjustment disorders, and to explore its mechanisms of action.

METHODS

This randomized controlled trial involved the assessment time points of pretreatment, posttreatment and 6-month follow-up. A total of 90 patients from three mental health units in Castellón, Spain, were recruited and randomly assigned to "ABCT + treatment as usual (TAU)," "Mindfulness-based stress reduction (MBSR) + TAU" or "TAU" alone. Affective distress, as measured by the "Depression, Anxiety and Stress Scales" (DASS-21) was the main outcome; self-compassion and mindfulness were also assessed. Multilevel mixed-effects models were used to estimate the effectiveness of the program, and path analyses were conducted to study the potential mechanistic role of mindfulness and self-compassion.

RESULTS

ABCT was not superior to MBSR in any outcome or at any assessment point. ABCT was superior to TAU alone both posttreatment (B = -13.20; 95% confidence interval [CI]: -19.57, -6.84) and at 6-month follow-up (B = -7.20; 95% CI: -13.63, -0.76) for reducing DASS-21, and MBSR was superior to TAU alone both posttreatment (B = -11.51; 95% CI: -17.97, -5.05) and at 6-month follow-up (B = -8.59; 95% CI: -15.09, -2.10), with large effects (d ≥ 0.90). Changes produced by ABCT in DASS-21 were mediated by self-compassion, whereas changes produced by MBSR were mediated by both mindfulness and self-compassion.

CONCLUSION

ABCT is effective for reducing affective distress in patients with anxiety, depressive and adjustment disorders, although its effect is not superior to that offered by MBSR. Self-compassion seems to be a significant mediator of the effects of ABCT.

Efficacy of the FIBROWALK Multicomponent Program Moved to a Virtual Setting for Patients with Fibromyalgia during the COVID-19 Pandemic: A Proof-of-Concept RCT Performed Alongside the State of Alarm in Spain

FIBROWALK is a multicomponent program including pain neuroscience education, therapeutic exercise, cognitive behavioral therapy and mindfulness training that has recently been found to be effective in patients with fibromyalgia (FM). This RCT started before the COVID-19 pandemic and was moved to a virtual format (i.e., online videos) when the lockdown was declared in Spain. This study is aimed to evaluate the efficacy of a virtual FIBROWALK compared to Treatment-As-Usual (TAU) in patients with FM during the first state of alarm in Spain. A total of 151 patients with FM were randomized into two study arms: FIBROWALK plus TAU vs. TAU alone. The primary outcome was functional impairment. Secondary outcomes were kinesiophobia, anxiety and depressive symptomatology, and physical functioning. Differences between groups at post-treatment assessment were analyzed using Intention-To-Treat (ITT) and completer approaches. Baseline differences between clinical responders and non-responders were also explored. Statistically significant improvements with small-to-moderate effect sizes were observed in FIBROWALK+TAU vs. TAU regarding functional impairment and most secondary outcomes. In our study, the NNT was 5, which was, albeit modestly, indicative of an efficacious intervention. The results of this proof-of-concept RCT preliminarily support the efficacy of virtual FIBROWALK in patients with FM during the Spanish COVID-19 lockdown.

Economic evaluations of educational, physical, and psychological treatments for fibromyalgia: a systematic review with meta-analysis

ABSTRACT

Nonpharmacological interventions are recommended for the treatment of fibromyalgia, but there is a lack of knowledge about the cost-effectiveness of these interventions. The aim of this study was to systematically review economic evaluations of educational, physical, and psychological interventions for the treatment of fibromyalgia. The search was performed in PUBMED, EMBASE, CINAHL, Cochrane Library, Physiotherapy Evidence Database, PsycINFO, EconLit, National Health Service Economic Evaluation Database, and Health Technology Assessment. Economic evaluations of educational, physical, and psychological interventions for adult patients with fibromyalgia were included. Primary outcomes were healthcare and societal costs, and quality-adjusted life-years, and secondary outcomes were any disease-specific clinical outcome. Costs and effects were pooled in a meta-analysis, when possible. Eleven studies were included, of which 7 compared a psychological intervention with another intervention or usual care/control. Over a 6-month time horizon, healthcare and societal costs of the psychological intervention were significantly lower than usual care (mean difference: $-2087, 95% confidence interval [CI]: -3061 to -1112; mean difference: $-2411, 95% CI: -3582 to -1240, respectively), and healthcare costs were significantly lower for the psychological intervention compared with a pharmacological intervention (mean difference: $-1443, 95% CI: -2165 to -721). Over a 12-month time horizon, healthcare costs for the psychological intervention were significantly lower than for usual care (mean difference: $-538, 95% CI: -917 to -158). Incremental cost-effectiveness ratios for quality-adjusted life-years and impact of fibromyalgia showed that the psychological intervention was cost-effective compared with other interventions and control conditions. There is a need of more economic evaluations conducted alongside randomized controlled trials with interventions recommended for the treatment of fibromyalgia, such as physical exercise.

Spa Therapy for the Treatment of Fibromyalgia: An Open, Randomized Multicenter Trial

Fibromyalgia is a common chronic pain pathology with an incidence of 4.3 per 1,000 person-years. An open, randomized clinical trial of patients with fibromyalgia comparing an immediate vs. delayed 18-day spa therapy in five spa therapy care facilities in France enrolled 220 patients. Randomization was in blocks of four, stratified by center, severity of fibromyalgia and previous spa therapy. Patients continued usual treatment. The main endpoint was the number of patients achieving minimal clinically important difference at 6 months, defined as 14% change in their baseline fibromyalgia impact questionnaire score. The intention-to-treat analysis included 100 and 106 patients in the intervention and control groups, respectively. At 6 months, 45/100 (45.0%) and 30/106 (28.3%) patients in the intervention and control groups, respectively, achieved a minimal clinically important difference (P= .013). There was also a significant improvement in pain, fatigue, and symptom severity (secondary outcomes) in the intervention group but not for generic quality of life (QOL), sleep or physical activity. None of the 33 serious adverse events reported by 25 patients were related to the spa therapy. Our results demonstrate the benefit of spa treatment in patients with fibromyalgia. PERSPECTIVE: A 12-month, open, randomized clinical trial of 220 patients with fibromyalgia compared an immediate versus delayed (ie, after 6 months) 18-day spa therapy. The results showed a clinically significant improvement at 6 months for those who received immediate therapy which was maintained up to 12 months. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov: NCT02265029.

Self-management for chronic widespread pain including fibromyalgia: A systematic review and meta-analysis

BACKGROUND

Chronic widespread pain (CWP) including fibromyalgia has a prevalence of up to 15% and is associated with substantial morbidity. Supporting psychosocial and behavioural self-management is increasingly important for CWP, as pharmacological interventions show limited benefit. We systematically reviewed the effectiveness of interventions applying self-management principles for CWP including fibromyalgia.

METHODS

MEDLINE, Embase, PsycINFO, The Cochrane Central Register of Controlled Trials and the WHO International Clinical Trials Registry were searched for studies reporting randomised controlled trials of interventions adhering to self-management principles for CWP including fibromyalgia. Primary outcomes included physical function and pain intensity. Where data were sufficient, meta-analysis was conducted using a random effects model. Studies were narratively reviewed where meta-analysis could not be conducted Evidence quality was rated using GRADE (Grading of Recommendations, Assessment, Development and Evaluations) (PROSPERO-CRD42018099212).

RESULTS

Thirty-nine completed studies were included. Despite some variability in studies narratively reviewed, in studies meta-analysed self-management interventions improved physical function in the short-term, post-treatment to 3 months (SMD 0.42, 95% CI 0.20, 0.64) and long-term, post 6 months (SMD 0.36, 95% CI 0.20, 0.53), compared to no treatment/usual care controls. Studies reporting on pain narratively had greater variability, however, those studies meta-analysed showed self-management interventions reduced pain in the short-term (SMD -0.49, 95% CI -0.70, -0.27) and long-term (SMD -0.38, 95% CI -0.58, -0.19) compared to no treatment/usual care. There were few differences in physical function and pain when self-management interventions were compared to active interventions. The quality of the evidence was rated as low.

CONCLUSION

Reviewed studies suggest self-management interventions can be effective in improving physical function and reducing pain in the short and long-term for CWP including fibromyalgia. However, the quality of evidence was low. Future research should address quality issues whilst making greater use of theory and patient involvement to understand reported variability.

The Role of Expectations and Endogenous Opioids in Mindfulness-Based Relief of Experimentally Induced Acute Pain

OBJECTIVE

Expectations contribute to cognitive pain modulation through opioidergically mediated descending inhibition. Mindfulness meditation reduces pain independent of endogenous opioids, engaging unique corticothalamocortical mechanisms. However, it remains unknown whether expectations for pain relief predict mindfulness-induced analgesia and if these expectations are modified by endogenous opioids.

METHODS

In this secondary analysis of previously published work, 78 pain-free participants (mean age, 27 ± 7 years; 50% women) were randomized to a four-session mindfulness meditation or book listening regimen. Expectations for intervention-induced pain relief were assessed before and after each intervention. Pain ratings were examined after meditation or rest (control group) during noxious heat (49°C) and intravenous administration of saline placebo or the opioid antagonist naloxone (0.15 mg/kg bolus + 0.1 mg kg-1 h-1 infusion.

RESULTS

Mindfulness significantly lowered pain during saline and naloxone infusion. Higher expected pain relief from mindfulness predicted lower pain intensity (r(40) = -0.41, p = .009). The relationship between meditation-related expectations and pain intensity reductions was exhibited during naloxone (r(20) = -0.76, p < .001) but not saline (r(20) = -0.22, p = .36). Expectations for book listening-based analgesia did not significantly predict pain changes during saline (r(20) = -0.37, p = .11) or naloxone (r(18) = 0.26, p = .30) in the control group.

CONCLUSIONS

These novel findings demonstrate a significant role for expectations in mindfulness-based pain relief. However, this role was minimal during saline and stronger during opioid blockade, despite similar pain reductions. This supports growing evidence that mindfulness engages multiple mechanisms to reduce pain, suggesting that mindfulness might be an effective pain-reducing technique even for individuals with low expectations for pain relief.

Psychoeducation for Patients with Fibromyalgia: A Systematic Review

This systematic review presents a brief and comprehensive summary of psychoeducational programs that have been designed for and tested in patients with fibromyalgia, with a focus on the features of the interventions and their main results regarding the patients’ clinical outcome. A bibliographical search performed in PubMed, Web of Science, Scopus, Cochrane Library and PsycInfo targeted publications, related to the terms “fibromyalgia” and “psychoeducation.” Information regarding the studies’ designs, age criterion, sample size, sex distribution and mean age of participants, and assessment time points, was recorded. If applicable, group distributions along with the main results regarding the patients’ clinical outcome, and features of the psychoeducational interventions were registered. Initial search eliciting 77 citations reduced to 10 relevant papers. Most of the reports come from two research projects from Spain (n = 6), worked with adult samples (n = 9), and most participants were females (88%–98%). Interventions reported significant improvements in the patients’ clinical outcomes in measures of pain intensity, fatigue, sleep quality, depression, anxiety, functional ability cognitive impairment, and quality of life. Results show not only that psychoeducational programs for the treatment of fibromyalgia are feasible, but also that they can be effective for managing physical and emotional symptoms, in particular, pain and depression.

Impact of mindfulness and self-compassion on anxiety and depression: The mediating role of resilience

Background/Objective 'Third-wave' psychotherapies have shown effectiveness for treating psychopathological symptoms such as anxiety and depression. There is burgeoning interest in examining how these therapies' core constructs produce their therapeutic benefits. This study explores the hypothetical mediating effect of resilience in the impact of mindfulness and self-compassion on anxiety and depressive symptoms. Method: Cross-sectional study design. The sample consisted of 860 Spanish general population participants. The measures included the Mindful Attention Awareness Scale (MAAS), the Self-Compassion Scale (SCS-12), the Connor-Davidson Resilience Scale (CD-RISC) and the Goldberg Anxiety and Depression Scale (GADS). Bivariate correlations were calculated, and path analysis models were performed. Results: Significant correlations were found between the study variables, always in the expected direction (all p values <.001). The path analysis models showed significant direct effects of mindfulness and self-compassion on anxiety and depression symptoms, but the only significant indirect effects through resilience were found on depression (MAAS: β = -.05, 95% CI = -.11 to -.02; SCS-12: β = -.06, 95% CI = -.33 to -.07). Conclusions: Resilience might partially mediate the effect of mindfulness and self-compassion on depression, but not on anxiety.

Protective role of mindfulness, self-compassion and psychological flexibility on the burnout subtypes among psychology and nursing undergraduate students

AIMS

To explore the relationship between mindfulness, self-compassion and psychological flexibility, and the burnout subtypes in university students of the Psychology and Nursing degrees, and to analyse possible risk factors for developing burnout among socio-demographic and studies-related characteristics.

DESIGN

Cross-sectional study conducted on a sample of 644 undergraduate students of Nursing and Psychology from two Spanish universities.

METHODS

The study was conducted between December 2015 and May 2016. Bivariate Pearson's correlations were computed to analyse the association between mindfulness facets, self-compassion and psychological flexibility, and levels of burnout. Multivariate linear regression models and bivariate and multivariate binary logistic regressions were also computed.

RESULTS

The three subtypes of burnout presented significant correlations with psychological flexibility, self-compassion and some mindfulness facets. Psychological flexibility, self-compassion and the mindfulness facets of observing and acting with awareness were significantly associated to burnout. Among the risk factors, 'year of study' was the only variable to show significantly higher risk for every burnout subtype.

CONCLUSION

The significant associations found between mindfulness, self-compassion, psychological flexibility and burnout levels underline the need of including these variables as therapeutic targets when addressing the burnout syndrome in university students.

IMPACT

Undergraduate students, especially those of health sciences, often experience burnout. This study delves into the protective role of some psychological variables: mindfulness, self-compassion and psychological flexibility. These should be considered as potentially protective skills for developing burnout, and therefore, undergraduate students could be trained on these abilities to face their studies and their future profession to prevent experiencing burnout syndrome.

Efficacy of a mindfulness-based programme with and without virtual reality support to reduce stress in university students: A randomized controlled trial

OBJECTIVES

To evaluate the efficacy of a mindfulness-based programme (MBP) for reducing stress in university students and its action mechanisms and to explore the capacity of virtual reality (VR) exposure to enhance adherence to the intervention.

METHODS

This randomized controlled trial (RCT) involved assessment time points of baseline, posttreatment, and 6-month follow-up. A total of 280 students from two Spanish universities were randomly assigned to 'MBP', 'MBP + VR', or 'Relaxation' (active controls). Perceived stress posttreatment was the primary outcome; wellbeing and academic functional outcomes were assessed as well. Multilevel mixed-effects models were performed to estimate the efficacy of the programme.

RESULTS

Both 'MBP' (B = -2.77, d = -0.72, p = .006) and 'MBP + VR' (B = -2.44, d = -0.59, p = .014) were superior to 'Relaxation' in improving stress, as well as most of the secondary outcomes, with medium-to-large effects posttreatment and at follow-up. The long-term effects of MBPs on stress were mediated by mindfulness and self-compassion in parallel. Treatment adherence was improved in the 'MBP + VR' group, with higher retention rates and session attendance (p < .001).

CONCLUSIONS

This RCT supports the efficacy of an MBP compared to relaxation for reducing stress in university students through mindfulness and self-compassion as mechanisms of change. VR exposure may enhance treatment adherence.

Mindfulness Practice for Glycemic Control: Could it be a New Strategy for an Old Problem? A Systematic Review and Meta-Analysis

BACKGROUND

The management of type 2 diabetes mellitus (T2DM) requires a complex and organized care that includes patient's lifestyle change. Additionally, emotional well-being is an important part of self-management, and it may impair the individual's adherence. Therefore, equipping the patients with the necessary coping and self-care techniques may be an important step in managing diabetes.

OBJECTIVE

To evaluate the effect of interventions using established mindfulness-based protocols on glycemic control of individuals with T2DM.

METHODS

Data sources: Two electronic databases (PubMed and EMBASE) were searched from inception to December 2019. We limited our search to published studies in English, Spanish and Portuguese languages.

STUDY SELECTION

Randomized clinical trials that assessed the effects of mindfulness in individuals with T2DM were selected.

DATA EXTRACTION

Two authors independently assessed the risk of bias and extracted data from the included trials. Data were pooled using inverse-variance random-effects meta-analyses. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system.

RESULTS

Four randomized trials were included. There were no differences in blood glucose change (mean difference between groups (MD) -0.73mg/dl; 95% CI, -10.49; 9.02; I2 =0%; very low quality of evidence) or glycated hemoglobin (MD 0.05%; 95%CI -0.22 to 0.32; I2 =29%; very low quality of evidence).

CONCLUSION

Although the quality of current evidence is very low, our findings suggest that established protocols involving mindfulness have no effect on blood glucose or glycated hemoglobin in individuals with T2DM. Indeed, large-scale trials are needed to evaluate the contribution of mindfulness to glycemic control in clinical practice. PROSPERO Registration ID: RD42020161940.

Subgrouping a Large U.S. Sample of Patients with Fibromyalgia Using the Fibromyalgia Impact Questionnaire-Revised

Fibromyalgia (FM) is a heterogeneous and complex syndrome; different studies have tried to describe subgroups of FM patients, and a 4-cluster classification based on the Fibromyalgia Impact Questionnaire-Revised (FIQR) has been recently validated. This study aims to cross-validate this classification in a large US sample of FM patients. A pooled sample of 6280 patients was used. First, we computed a hierarchical cluster analysis (HCA) using FIQR scores at item level. Then, a latent profile analysis (LPA) served to confirm the accuracy of the taxonomy. Additionally, a cluster calculator was developed to estimate the predicted subgroup using an ordinal regression analysis. Self-reported clinical measures were used to examine the external validity of the subgroups in part of the sample. The HCA yielded a 4-subgroup distribution, which was confirmed by the LPA. Each cluster represented a different level of severity: “Mild–moderate”, “moderate”, “moderate–severe”, and “severe”. Significant differences between clusters were observed in most of the clinical measures (e.g., fatigue, sleep problems, anxiety). Interestingly, lower levels of education were associated with higher FM severity. This study corroborates a 4-cluster distribution based on FIQR scores to classify US adults with FM. The classification may have relevant clinical implications for diagnosis and treatment response.

An exploratory clinical trial on acceptance and commitment therapy as an adjunct to psychoeducational relaxation therapy for chronic pain

Objective: The aim of this study was to compare the clinical efficacy of two differently-designed psychological interventions for chronic pain.Design: 138 patients presenting chronic pain were randomly assigned to one of two experimental conditions: (1) Psychoeducational relaxation therapy (PRT, n = 84) or (2) PRT followed by acceptance and commitment therapy (PRT + ACT, n = 54).Main outcome measures: Pain intensity, quality of life (SF-36), anxiety and depression (HADS), stress (PSS), pain catastrophizing (PCS), chronic pain acceptance (CPAQ), and psychological inflexibility (PIPS) were assessed at three time-points: before therapy (T1); at the end of the therapy (T2); and 3- months after the end of the therapy (T3).Results: In T2, the PRT intervention showed more significant improvements in the measures of mental quality of life [F (1,92) = 7.478, P < .05] and depression [F (1, 92) = 5.804, P < .05] compared to the PRT + ACT intervention. The experimental groups did not differ in their outcome measures at T3.Conclusion: PRT appears to be an effective solution in the psychological care of chronic pain. The effectiveness of this type of intervention seems to have been underestimated. The addition of ACT sessions did not significantly impact the results, indicating that both designs of interventions are effective in the short term.

Differential efficacy between cognitive-behavioral therapy and mindfulness-based therapies for chronic pain: Systematic review

Background/Objective: To assess the differential efficacy between mindfulness-based interventions and cognitive-behavioral Therapy (CBT) on chronic pain across medical conditions involving pain. Method: ProQuest, Science Direct, Google Scholar, Pubmed, and Embase databases were searched to identify randomized clinical trials. Measurements of mindfulness, pain, mood, and further miscellaneous measurements were included. Results: 18 studies met the inclusion criteria (fibromyalgia, n = 5; low back pain, n = 5; headache/migraine, n = 4; non-specific chronic pain, n = 4). In fibromyalgia, mindfulness based stress reduction (MBSR) was superior to the usual care and Fibroqol, in impact and symptoms. In low back pain, MBSR was superior to the usual care, but not to CBT, in physical functionality and pain intensity. There were no studies on differential efficacy between mindfulness and CBT for headache and non-specific chronic pain, but Mindfulness interventions were superior to the usual care in these syndromes. Conclusions: Mindfulness interventions are superior to usual cares in all diagnoses, but it is not possible to conclude their superiority over CBT. Comparisons between mindfulness interventions are scarce, with MBSR being the most studied. In central sensitization syndromes, variables associated with pain tend to improve with treatment. More research is needed to differentiate diagnosis and intervention.

Effectiveness of a Multicomponent Treatment for Fibromyalgia Based on Pain Neuroscience Education, Exercise Therapy, Psychological Support, and Nature Exposure (NAT-FM): A Pragmatic Randomized Controlled Trial

A recent study (FIBROWALK has supported the effectiveness of a multicomponent treatment based on pain neuroscience education (PNE), exercise therapy (TE), cognitive behavioral therapy (CBT), and mindfulness in patients with fibromyalgia. The aim of the present RCT was: (a) to analyze the effectiveness of a 12-week multicomponent treatment (nature activity therapy for fibromyalgia, NAT-FM) based on the same therapeutic components described above plus nature exposure to maximize improvements in functional impairment (primary outcome), as well as pain, fatigue, anxiety-depression, physical functioning, positive and negative affect, self-esteem, and perceived stress (secondary outcomes), and kinesiophobia, pain catastrophizing thoughts, personal perceived competence, and cognitive emotion regulation (process variables) compared with treatment as usual (TAU); (b) to preliminarily assess the effects of the nature-based activities included (yoga, Nordic walking, nature photography, and Shinrin Yoku); and (c) to examine whether the positive effects of TAU + NAT-FM on primary and secondary outcomes at post-treatment were mediated through baseline to six-week changes in process variables. A total of 169 FM patients were randomized into two study arms: TAU + NAT-FM vs. TAU alone. Data were collected at baseline, at six-week of treatment, at post-treatment, and throughout treatment by ecological momentary assessment (EMA). Using an intention to treat (ITT) approach, linear mixed-effects models and mediational models through path analyses were computed. Overall, TAU + NAT-FM was significantly more effective than TAU at posttreatment for the primary and secondary outcomes evaluated, as well as for the process variables. Moderate-to-large effect sizes were achieved at six-weeks for functional impairment, anxiety, kinesiophobia, perceived competence, and positive reappraisal. The number needed to treat (NNT) was 3 (95%CI = 1.6-3.2). The nature activities yielded an improvement in affective valence, arousal, dominance, fatigue, pain, stress, and self-efficacy. Kinesiophobia and perceived competence were the mediators that could explain a significant part of the improvements obtained with TAU + NAT-FM treatment. TAU + NAT-FM is an effective co-adjuvant multicomponent treatment for improving FM-related symptoms.

Mindfulness-Based Program Plus Amygdala and Insula Retraining (MAIR) for the Treatment of Women with Fibromyalgia: A Pilot Randomized Controlled Trial

The lack of highly effective treatments for fibromyalgia (FM) represents a great challenge for public health. The objective of this parallel, pilot randomized controlled trial (RCT) was two-fold: (1) to analyze the clinical effects of mindfulness plus amygdala and insula retraining (MAIR) compared to a structurally equivalent active control group of relaxation therapy (RT) in the treatment of FM; and (2) to evaluate its impact on immune-inflammatory markers and brain-derived neurotrophic factor (BDNF) in serum. A total of 41 FM patients were randomized into two study arms: MAIR (intervention group) and RT (active control group), both as add-ons of treatment as usual. MAIR demonstrated significantly greater reductions in functional impairment, anxiety, and depression, as well as higher improvements in mindfulness, and self-compassion at post-treatment and follow-up, with moderate to large effect sizes. Significant decreases in pain catastrophizing and psychological inflexibility and improvements in clinical severity and health-related quality of life were found at follow-up, but not at post-treatment, showing large effect sizes. The number needed to treat was three based on the criteria of ≥50% Fibromyalgia Impact Questionnaire (FIQ) reduction post-treatment. Compared to RT, the MAIR showed significant decreases in BDNF. No effect of MAIR was observed in immune-inflammatory biomarkers (i.e., TNF-α, IL-6, IL-10, and hs-CRP). In conclusion, these results suggest that MAIR, as an adjuvant of treatment-as-usual (TAU), appears to be effective for the management of FM symptoms and for reducing BDNF levels in serum.

Practical Strategies for Identifying and Managing Burnout in Plastic Surgeons

BACKGROUND

Physician burnout is a well-known problem and widespread issue in the field of medicine. Recently, more attention has been given to the significance of burnout among plastic surgeons. The cause of burnout is multifactorial, with emotional exhaustion, depersonalization, and a reduced sense of personal accomplishment all playing a role. The objective of this article is to provide practical measures to help plastic surgeons in identifying the signs of burnout, thereby mitigating its consequences.

METHODS

A literature review was performed to determine the comprehensive findings of previous research conducted on burnout among plastic surgeons. Particular interest was given to successful tactics used in managing work-related stress. Wellness strategies and resources from both academic and private medical settings were also obtained to further review methods for burnout management.

RESULTS

There is a wide range of causes and risk factors for burnout among plastic surgeons. The majority of cases correlate with increased workload, loss of physician autonomy, and, in the context of trainees, lack of mentorship. Managing burnout can be supported by identification through survey tools. Establishing a wellness committee is also useful to develop institution-specific interventions. Equally as important, individuals must take steps to manage and minimize their burnout.

CONCLUSIONS

This article provides practical strategies for institutions to identify and manage burnout among plastic surgeons. It is obvious that causes of burnout vary in different settings such as academic and community hospitals; therefore, it is critical for institutions to individualize their approach to burnout.

The Effect of Mindfulness-Based Stress Reduction (MBSR) on Depression, Cognition, and Immunity in Mild Cognitive Impairment: A Pilot Feasibility Study

BACKGROUND

Mindfulness-based programs have shown a promising effect on several health factors associated with increased risk of dementia and the conversion from mild cognitive impairment (MCI) to dementia such as depression, stress, cognitive decline, immune system and brain structural and functional changes. Studies on mindfulness in MCI subjects are sparse and frequently lack control intervention groups.

OBJECTIVE

To determine the feasibility and the effect of mindfulness-based stress reduction (MBSR) practice on depression, cognition and immunity in MCI compared to cognitive training.

METHODS

Twenty-eight MCI subjects were randomly assigned to two groups. MBSR group underwent 8-week MBSR program. Control group underwent 8-week cognitive training. Their cognitive and immunological profiles and level of depressive symptoms were examined at baseline, after each 8-week intervention (visit 2, V2) and six months after each intervention (visit 3, V3). MBSR participants completed feasibility questionnaire at V2.

RESULTS

Twenty MCI patients completed the study (MBSR group n=12, control group n=8). MBSR group showed significant reduction in depressive symptoms at both V2 (p=0.03) and V3 (p=0.0461) compared to the baseline. There was a minimal effect on cognition - a group comparison analysis showed better psychomotor speed in the MBSR group compared to the control group at V2 (p=0.0493) but not at V3. There was a detectable change in immunological profiles in both groups, more pronounced in the MBSR group. Participants checked only positive/neutral answers concerning the attractivity/length of MBSR intervention. More severe cognitive decline (PVLT≤36) was associated with the lower adherence to home practice.

CONCLUSION

MBSR is well-accepted potentially promising intervention with positive effect on cognition, depressive symptoms and immunological profile.

Efficacy, cost-utility and physiological effects of Acceptance and Commitment Therapy (ACT) and Behavioural Activation Treatment for Depression (BATD) in patients with chronic low back pain and depression: study protocol of a randomised, controlled trial including mobile-technology-based ecological momentary assessment (IMPACT study)

INTRODUCTION

The IMPACT study focuses on chronic low back pain (CLBP) and depression symptoms, a prevalent and complex problem that represents a challenge for health professionals. Acceptance and Commitment Therapy (ACT) and Brief Behavioural Activation Treatment for Depression (BATD) are effective treatments for patients with persistent pain and depression, respectively. The objectives of this 12 month, multicentre, randomised, controlled trial (RCT) are (i) to examine the efficacy and cost-utility of adding a group-based form of ACT or BATD to treatment-as-usual (TAU) for patients with CLBP and moderate to severe levels of depressive symptoms; (ii) identify pre-post differences in levels of some physiological variables and (iii) analyse the role of polymorphisms in the FKBP5 gene, psychological process measures and physiological variables as mediators or moderators of long-term clinical changes.

METHODS AND ANALYSIS

Participants will be 225 patients with CLBP and moderate to severe depression symptoms recruited at Parc Sanitari Sant Joan de Déu (St. Boi de Llobregat, Spain) and Hospital del Mar (Barcelona, Spain), randomly allocated to one of the three study arms: TAU vs TAU+ACT versus TAU+BATD. A comprehensive assessment to collect clinical variables and costs will be conducted pretreatment, post-treatment and at 12 months follow-up, being pain interference the primary outcome measure. The following physiological variables will be considered at pretreatment and post-treatment assessments in 50% of the sample: immune-inflammatory markers, hair cortisol and cortisone, serum cortisol, corticosteroid-binding globulin and vitamin D. Polymorphisms in the FKBP5 gene (rs3800373, rs9296158, rs1360780, rs9470080 and rs4713916) will be analysed at baseline assessment. Moreover, we will include mobile-technology-based ecological momentary assessment, through the Pain Monitor app, to track ongoing clinical status during ACT and BATD treatments. Linear mixed-effects models using restricted maximum likelihood, and a full economic evaluation applying bootstrapping techniques, acceptability curves and sensitivity analyses will be computed.

ETHICS AND DISSEMINATION

This study has been approved by the Ethics Committee of the Fundació Sant Joan de Déu and Hospital del Mar. The results will be actively disseminated through peer-reviewed journals, conference presentations, social media and various community engagement activities.

The Bed Nucleus of the Stria Terminalis as a Brain Correlate of Psychological Inflexibility in Fibromyalgia

This study explored the brain structural correlates of psychological flexibility (PF) as measured with the Psychological Inflexibility in Pain Scale (PIPS) in patients with fibromyalgia (FM). Structural magnetic resonance imaging data from 47 FM patients were used to identify Gray Matter Volume (GMV) alterations related to PIPS scores. Brain GMV clusters related to PIPS were then correlated with clinical and cognitive variables to further explore how emerged brain clusters were intertwined with FM symptomatology. Longitudinal changes in PIPS-related brain clusters values were assessed by studying pre–post data from 30 patients (15 allocated to a mindfulness-based stress reduction (MBSR) program and 15 to treatment-as-usual). Changes in PIPS-related brain clusters were also explored in participants showing greater/lower longitudinal changes in PIPS scores. PIPS scores were positively associated with GMV in a bilateral cluster in the ventral part of the bed nucleus of the stria terminalis (BNST). Significant associations between BNST cluster with functional impairment, depressive symptomatology, perceived stress and the nonjudging mindfulness facet were observed. Participants reporting greater pre–post increases in PIPS scores showed greater increases in BNST cluster values. These findings contribute to the understanding on the neurobiological bases of PF in FM and encourage further explorations of the role of the BNST in chronic pain.
