Objectives Chronic vulvar pain (CVP) is pain in the vulvar area exceeding three months of duration. Previous studies have reported a prevalence of 7–8% in the general population and observed an association between CVP and other chronic pain, affective disorders and early life stressors. The aim of this study was to estimate the prevalence of CVP among gynecological outpatients and to explore its association with child sexual abuse, comorbid fibromyalgia and mental health. Methods We conducted a questionnaire-based cross-sectional study among consecutive women attending an unselected general gynecological outpatient clinic at St Olav’s University Hospital, Trondheim, Norway, during the period August 1st, 2017, to June 30th, 2018. CVP was defined as having experienced either vulvar burning, sharp pain or allodynia for three months or more within the previous year. Fibromyalgia was defined as widespread pain in the past six months in conjunction with a symptom severity score ≥5 on the fibromyalgia symptom severity score inventory, an ordinal scale from zero to 12. We collected information on sexual coercion experience and assessed mental health with the mental health inventory (MHI-5) of the SF-36 health survey, which yields a zero to five scale. Results Of 1,125 questionnaires distributed, 810 (72%) were returned, and 762 (68%) included in final analyses. Among these, 130 (17.1%) reported CVP within the previous year and 92 (16.7%) were classified as suffering from fibromyalgia. Fibromyalgia was associated with CVP (adjusted OR of 1.8, 95% CI 1.1–3.1). Child sexual abuse was reported by 96 (13.1%) and was associated with CVP (adjusted OR 2.0, 95% CI 1.2–3.3). CVP and fibromyalgia were both associated with lower mental health scores; 0.51 and 0.58 points on the MHI-5 scale, respectively. Conclusions Chronic vulvar pain is common among women in a gynecological outpatient clinic and associated with child sexual abuse, comorbid fibromyalgia and worse mental health.

The pathophysiology of fibromyalgia syndrome (FMS) remains elusive, leading to a lack of objective diagnostic criteria and targeted treatment. We globally evaluated immune system changes in FMS by conducting multiparametric flow cytometry analyses of peripheral blood mononuclear cells and identified a natural killer (NK) cell decrease in patients with FMS. Circulating NK cells in FMS were exhausted yet activated, evidenced by lower surface expression of CD16, CD96, and CD226 and more CD107a and TIGIT. These NK cells were hyperresponsive, with increased CCL4 production and expression of CD107a when co-cultured with human leukocyte antigen null target cells. Genetic and transcriptomic pathway analyses identified significant enrichment of cell activation pathways in FMS driven by NK cells. Skin biopsies showed increased expression of NK activation ligand, unique long 16-binding protein, on subepidermal nerves of patients FMS and the presence of NK cells near peripheral nerves. Collectively, our results suggest that chronic activation and redistribution of circulating NK cells to the peripheral nerves contribute to the immunopathology associated with FMS.

Background and aims The ACR1990 criteria of fibromyalgia (FM) have been criticized due to poor reliability of tender points counting (TPC), inconsistent definitions of the widespread pain, and by not considering other symptoms than pain in the FM phenotype. Therefore, several newer self-report measures for FM criteria have emerged. The aim of this study was to translate the fibromyalgia survey questionnaire (FSQ) to Norwegian and validate both the 2011 and the 2016 fibromyalgia survey diagnostic criteria (FSDC) against the ACR1990 criteria. Methods One hundred and twenty chronic pain patients formerly diagnosed with fibromyalgia according to the ACR1990 criteria, and 62 controls not diagnosed or where fibromyalgia was not suspected, were enrolled in this study. All responded to a Norwegian version of the FSQ. Also, they had a clinical examination according to ACR1990 fibromyalgia criteria including a counting of significant tender points with an algometer (TPC). The FSQ with the Widespread Pain Index (WPI) and Symptom Severity scale (SSS) subscales, Fibromyalgia Severity (FS) sum score, was examined for correlations with the fibromyalgia impact questionnaire (FIQ) and TPCs. Face-validity, internal consistence, test-retest reliability and construct validity with convergent and divergent approaches were examined and a Receiver Operating Characteristics (ROC) analysis was performed. Results The internal consistency of FS measured by Cronbach’s alfa was good (=0.904). The test-retest reliability measures using intra class correlation were respectable for the FS, including WPI and SSS subscales (0.86, 0.84 and 0.87). FS, WPI and SSS correlated significantly with FIQ (0.74, 0.59 and 0.85) and TPC indicating an adequate construct, convergent validity. The medians of FS, WPI and SSS in the fibromyalgia-group were significantly different from the non-fibromyalgia-group indicating good construct, divergent validity. Using the 2011 and 2016 FSDC vs. ACR 1990 as a reference, sensitivity, specificity, positive likelihood ratio (LR +) and negative likelihood ratio (LR−) were identified. The accuracy rate for both 2011 and 2016 FSDC were respectable (84%). ROC analysis using FS revealed a very good Area Under the Curve (AUC) = 0.860. Conclusion The current study revealed that the Norwegian versions of FSQ is a valid tool for assessment of fibromyalgia according to the 2011 and 2016 (FSDC).

The International Classification of Diseases, 11th Revision (ICD-11), proposes, for the first time, a coding system for chronic pain. This system contains 1 code for "chronic primary pain," where chronic pain is the disease, and 6 codes for chronic secondary pain syndromes, where pain developed in the context of another disease. This provides the opportunity for routine, standardised coding of chronic pain throughout all health care systems. In primary care, this will confer many important, novel advantages over current or absent coding systems. Chronic pain will be recognized as a centrally important condition in primary care. The capacity to measure incidence, prevalence, and impact will help in identification of human, financial, and educational needs required to address chronic pain in primary care. Finally, opportunities to match evidence-based treatment pathways to distinct chronic pain subtypes will be enhanced.

Background There is growing evidence that the kynurenine pathway is involved in the pathology of diseases related to the central nervous system (CNS), because of the neuroprotective or neurotoxic properties of certain metabolites, yet the role of each metabolite is not clear. The pathology of Chronic Fatigue Syndrome (CFS) and Fibromyalgia (FM) is currently under investigation, and the overlapping symptoms such as depression suggest that the CNS may be involved. These symptoms may be driven by enhanced neurotoxicity and/or diminished neuroprotection. However, the kynurenine metabolite status has not been well studied in these two possible related disorders of CFS and FM. The objective of this study was to investigate the metabolites and ratios of the kynurenine pathway in CFS and FM compared to healthy controls and examine the possible correlations with symptoms of anxiety and depression. Method In this study, females aged 18–60 were included: 49 CFS patients; 57 FM patients; and 54 healthy controls. Blood plasma was analysed for the following metabolites involved in the kynurenine pathway: Tryptophan, kynurenine, kynurenic acid (KA), 3-hydroxykykynurenine (HK), anthranilic acid, xanthurenic acid (XA), 3-hydroxyanthranilic acid, quinolinic acid (QA) and picolinic acid. The concentrations of these metabolites, as well as the ratios of different metabolites indicating enzymatic activity, were compared between the groups. Findings were controlled for age, body mass index (BMI), and symptoms of anxiety and depression. Results QA differed between CFS and FM patients (β = .144, p = .036) and was related to higher levels of BMI (β = .017, p = .002). The neuroprotective ratio given by KA/QA was lower for CFS patients compared to healthy controls (β = −.211, p = .016). The neuroprotective ratio given by KA/HK was lower for FM patients compared to healthy controls, and this lower neuroprotective ratio was associated with increased symptoms of pain. The kynurenine aminotransferase II (KAT II) enzymatic activity given by XA/HK was lower for FM patients compared to healthy controls (β = −.236, p = .013). In addition, BMI was negatively associated with enhanced KAT II enzymatic activity (β = −.015, p = .039). Symptoms of anxiety and depression were not associated with the metabolites or ratios studied. Conclusion Our study indicates associations between kynurenine metabolism and CFS and FM as well as characteristic symptoms like fatigue and pain. Forthcoming studies indicating a causative effect may place kynurenine metabolites as a target for treatment as well as prevention of these conditions in the future.

Purpose The aim of this study was to evaluate potential barriers and facilitators for implementing motivational interviewing (MI) as a return to work (RTW) intervention in a Norwegian social insurance setting. Methods A mixed-methods process evaluation was conducted alongside a randomized controlled trial involving MI sessions delivered by social insurance caseworkers. The study was guided by the Reach, Efectiveness, Adoption, Implementation, and Maintenance framework using focus groups with the caseworkers. MI fdelity was evaluated through audio-recordings of MI sessions and questionnaires to sick-listed participants. Results Lack of co-worker and managerial support, time and place for practicing to further develop MI skills, and a high workload made the MI intervention challenging for the caseworkers. The MI method was experienced as useful, but difcult to master. MI fdelity results showed technical global scores over the threshold for “beginning profciency” whereas the relational global score was under the threshold. The sick-listed workers reported being satisfed with the MI sessions. Conclusions Despite caseworker motivation for learning and using MI in early follow-up sessions, MI was hard to master and use in practice. Several barriers and facilitators were identifed; these should be addressed before implementing MI in a social insurance setting.

Summary Osteoarthritis affects over 300 million people worldwide. Here, we conduct a genome-wide association study meta-analysis across 826,690 individuals (177,517 with osteoarthritis) and identify 100 independently associated risk variants across 11 osteoarthritis phenotypes, 52 of which have not been associated with the disease before. We report thumb and spine osteoarthritis risk variants and identify differences in genetic effects between weight-bearing and non-weight-bearing joints. We identify sex-specific and early age-at-onset osteoarthritis risk loci. We integrate functional genomics data from primary patient tissues (including articular cartilage, subchondral bone, and osteophytic cartilage) and identify high-confidence effector genes. We provide evidence for genetic correlation with phenotypes related to pain, the main disease symptom, and identify likely causal genes linked to neuronal processes. Our results provide insights into key molecular players in disease processes and highlight attractive drug targets to accelerate translation., Graphical abstract, Highlights • A multicohort study identifies 52 previously unknown osteoarthritis genetic risk variants • Similarities and differences in osteoarthritis genetic risk depend on joint sites • Osteoarthritis genetic components are associated with pain-related phenotypes • High-confidence effector genes highlight potential targets for drug intervention, A multicohort genome-wide association meta-analysis of osteoarthritis highlights the impact of joint site types on the features of genetic risk variants and the link between osteoarthritis genetics and pain-related phenotypes, pointing toward potential targets for therapeutic intervention.

Background and ObjectivesChronic widespread musculoskeletal pain (CWP) is a symptom of fibromyalgia and a complex trait with poorly understood pathogenesis. CWP is heritable (48-54%), but its genetic architecture is unknown and candidate gene studies have produced inconsistent results. We conducted a genome-wide association study to get insight into the genetic background of CWP.MethodsNorthern Europeans from UK Biobank comprising 6,914 cases reporting pain all over the body lasting more than 3 months and 242,929 controls were studied. Replication of three lead genome-wide significant single nucleotide polymorphisms (SNPs) was attempted in 6 independent European cohorts (N=43,080; cases=14,177). Genetic correlations with risk factors, tissue specificity, and colocalization were examined.ResultsThree genome-wide significant loci were identified (rs1491985, rs10490825, rs165599) residing within the genes RNF123, ATP2C1, and COMT. The RNF123 locus was replicated (meta-analysis p=0.0002), the ATP2C1 locus showed suggestive association (p=0.0227), and the COMT locus was not replicated. Partial genetic correlation between CWP and depressive symptoms, body mass index, age of first birth, and years of schooling were identified. Tissue specificity and colocalization analysis highlight the relevance of skeletal muscle in CWP.ConclusionsWe report a novel association of RNF123 locus with CWP and suggest a role of ATP2C1, consistent with a role of calcium regulation in CWP. The association to COMT, one of the most studied genes in chronic pain field, was not confirmed in the replication analysis.Key messagesWhat is already known about this subject?Chronic widespread musculoskeletal pain (CWP) is a primary diagnostic feature of fibromyalgia.CWP is moderately heritable, but precise genes involved in the pathogenesis of CWP are yet to be identified.What does this study add?This is the largest genetic study conducted on CWP to date and identified novel genetic risk loci (RNF123 and ATP2C1).The genetic signal points to peripheral pain mechanisms in CWP, and shows genetic correlation with other traits, including BMI and depression.How might this impact on clinical practice or future developments?The findings add to etiological basis of CWP.

Background When returning to work after being on long-term sick leave, individuals may experience varying levels of motivation and self-efficacy. Motivational interviewing (MI) is a counseling style that aims to increase motivation towards change, and it may be useful in the return to work (RTW) process. The aim of this study was to explore sick-listed workers’ experiences with MI in the RTW process. Methods This qualitative study was part of a randomized controlled trial evaluating the effects of MI on the RTW process, and it was administered by caseworkers at the Norwegian Labor and Welfare Administration. Sixteen sick-listed individuals, aged 33–60, participated in semi-structured interviews. All had a sick leave status of 50–100% for at least 8 weeks when interviewed and all had completed 2 MI sessions. The data was analyzed with systematic text condensation. Results Participants’ experiences of the MI sessions were categorized into three themes: (1) relationship with the MI caseworker, (2) normalizing sick leave, and (3) adjusting RTW strategies. The MI sessions were experienced as a positive encounter due to the supportive relationship that was built between the MI caseworker and the sick-listed worker. Being sick listed led to feelings of guilt and stigmatization, but acceptance and support from the MI caseworkers helped normalize the situation for the sick-listed workers. Furthermore, MI sessions allowed for personalized feedback and discussions on adjustments to their RTW strategies. Conclusion Sick-listed workers experienced MI as positive due to the good relationship that developed with the MI caseworker, how this normalized sick leave, and the help they received with adjusting their RTW strategies. Professionals working with individuals attempting to RTW may benefit from using MI as a method for helping sick-listed workers to RTW. Trial registration ClinicalTrials.gov: NCT03212118 (registered July 11, 2017).

Purpose: The reports regarding the status of the immune system in patients with chronic fatigue syndrome/myalgic encephalopathy (CFS/ME) have been inconclusive. We approached this question by comparing a strictly defined group of CFS/ME outpatients to healthy control individuals, and thereafter studied cytokines in subgroups with various psychiatric symptoms. Materials and methods: Twenty patients diagnosed with CFS/ME according to the Fukuda criteria and 20 age- and sex-matched healthy controls were enrolled in the study. Plasma was analysed by ELISA for levels of the cytokines TNF-α, IL-4, IL-6 and IL-10. Participants also answered questionnaires regarding health in general, and psychiatric symptoms in detail. Results: Increased plasma levels of TNF-α in CFS/ME patients almost reached significance compared to healthy controls (p = .056). When studying the CFS/ME and control groups separately, there was a significant correlation between TNF-α and The Hospital Anxiety and Depression Scale (HADS) depressive symptoms in controls only, not in the CFS/ME group. A correlation between IL-10 and psychoticism was found in both groups, whereas the correlation for somatisation was seen only in the CFS/ME group. When looking at the total population, there was a significant correlation between TNF-α and both the HADS depressive symptoms and the SCL-90-R cluster somatisation. Also, there was a significant association between IL-10 and the SCL-90-R cluster somatisation when analyzing the cohort (patients and controls together). Conclusions: These findings indicate that immune activity in CFS/ME patients deviates from that of healthy controls, which implies potential pathogenic mechanisms and possible therapeutic approaches to CFS/ME. More comprehensive studies should be carried out on defined CFS/ME subgroups. (C) 2018 The Author(s).

The role of the immune system in the pathogenesis of Fibromyalgia (FM) and Chronic fatigue syndrome (CFS) is not clear. We have previously reported increased levels of C-reactive protein (CRP) in these patient groups compared to healthy controls and wanted to further explore the levels of circulating immune markers in these populations. The population consisted of three groups, 58 patients with FM, 49 with CFS and 54 healthy controls. All participants were females aged 18–60. Patients were recruited from a specialised university hospital clinic and controls were recruited by advertisement among the staff and students at the hospital and university. Plasma levels of Interferon (IFN)-γ, Interleukin (IL)-1β, IL-1ra, IL-4, IL-6, IL-8, IL-10, IL-17, Interferon gamma-induced protein (IP)-10, Monocyte Chemoattractant Protein (MCP)-1, Transforming Growth Factor (TGF)-β1, TGF-β2, TGF-β3 and Tumour Necrosis Factor (TNF)-α were analysed by multiplex. Differences between the three groups CFS, FM and controls, were analysed by Kruskal Wallis tests. MCP-1 was significantly increased in both patient groups compared to healthy controls. IL-1β, Il-4, IL-6, TNF-α, TGF-β1, TGF-β2, TGF-β3, IL-10 and IL17 all were significantly lower in the patient groups than healthy controls. IFN-γ was significantly lower in the FM group. For IL-8, IL-10 and IL-1ra there were no significant difference when controlled for multiple testing. In conclusion, in our material MCP-1 seems to be increased in patients both with CFS and with FM, while several other immune markers are significantly lower in patients than controls., Highlights • MCP-1 is significantly increased in CFS and Fibromyalgia compared to controls. • CFS and Fibromyalgia share common features of inflammation. • Decreased IL-1β, IL-4, IL-6, TNF-α, TGF-β1, TGF-β2, TGF-β3, IL-10 and IL-17A are found in both CFS and Fibromyalgia.

Breast cancer is the leading cause of cancer in women worldwide. Exercise interventions may improve physical and psychological factors during and after active breast cancer treatment. The aim of this systematic review was to assess the current knowledge regarding the efficacy of physical exercise with respect to fatigue and self-reported physical functioning. Systematic searches in Cochrane Library, Medline, Embase, Cinahl, PsycINFO, AMED and PEDro. After assessing the quality of the studies, we identified 25 randomized controlled trials that included 3418 breast cancer patients. An increase in physical functioning and a decrease in fatigue were observed after a physical exercise intervention, with an SMD of 0.27 (0.12, 0.41) and −0.32 (−0.49, - 0.14), respectively. There were slightly higher improvements in physical functioning and fatigue when the patients received the intervention after adjuvant breast cancer treatment. The 6-month follow-up data showed a small favourable difference for the physical exercise group for both physical functioning and fatigue. This systematic review found that an exercise intervention program can produce short-term improvements in physical functioning and can reduce fatigue in breast cancer patients. However, more studies are needed to confirm the time-dependent observations in this study.

The aim of this study was to examine the association between fibromyalgia pain and weather, and to investigate whether psychosocial factors influence this relationship. Women with chronic widespread pain/fibromyalgia (N = 50) enrolled in a larger study, were recruited from a 4-week inpatient rehabilitation program in Norway ( 2009-2010), and reported their pain and psychological factors up to three times per day (morning, afternoon, evening) for 5 weeks. These ratings were then related to the official local weather parameters. Barometric pressure recorded simultaneously impacted pain significantly while temperature, relative humidity, and solar flux did not. No psychological variables influenced the weather-pain interaction. No weather parameter predicted change in the subsequent pain measures. The magnitude of the inverse association between pain and barometric pressure was very small, and none of the psychological variables studied influenced the association between pain and barometric pressure. All in all, the evidence for a strong weather-pain association in fibromyalgia seems limited at best.

Patients with chronic nonmalignant pain syndromes frequently report cognitive dysfunction, in particular with respect to concentration and attention. Such complaints have, in general, been attributed to depressive symptoms. In this study we showed that cognitive complaints in chronic pain patients are significantly associated with objective test performance in the area of inhibitory control after partialling out degree of depressive symptoms. Furthermore, about 20% of the patients performed below cut-off for clinically significant impairment on tests of basic neurocognitive functioning. A larger proportion of patients with generalized and neuropathic pain performed below this cut-off, whereas patients with localized pain exhibited impaired function to a lesser degree. Chronic pain patients receiving opioids did not perform worse than patients off opioid treatment. Systematic assessment of basic neurocognitive functions in centres treating chronic pain patients is warranted.

STUDY DESIGN: A randomized controlled trial. OBJECTIVE: The aim of this study was to evaluate whether a tailored and manualized cognitive behavior therapy (CBT) or nutritional supplements of seal oil and soy oil had any additional benefits over a brief cognitive intervention (BI) on return to work (RTW). SUMMARY OF BACKGROUND DATA: Brief intervention programs are clinically beneficial and cost-effective for patients with low back pain (LBP). CBT is recommended for LBP, but evidence on RTW is lacking. Seal oil has previously been shown to have a possible effect on muscle pain, but no randomized controlled trials have so far been carried out in LBP patients. METHODS: Four hundred thirteen adults aged 18 to 60 years were included. Participants were sick-listed 2 to 10 months due to LBP. Main outcome was objectively ascertained work participation at 12-month follow-up. Participants were randomly assigned to BI (n = 100), BI and CBT (n = 103), BI and seal oil (n = 105), or BI and soy oil (n = 105). BI is a two-session cognitive, clinical examination program followed by two booster sessions, while the CBT program is a tailored, individual, seven-session manual-based treatment. RESULTS: At 12-month follow-up, 60% of the participants in the BI group, 50% in the BI and CBT group, 51% in the BI and seal oil group, and 53% in the BI and soy oil group showed reduced sick leave from baseline, and had either partly or fully RTW. The differences between the groups were not statistically significant (χ = 2.54, P = 0.47). There were no significant differences between the treatment groups at any of the other follow-up assessments either, except for a significantly lower sick leave rate in the BI group than the other groups during the first 3 months of follow-up (χ = 9.50, P = 0.02). CONCLUSION: CBT and seal oil had no additional benefits over a brief cognitive intervention on sick leave. The brief cognitive intervention alone was superior in facilitating a fast RTW. Cognitive Interventions and Nutritional Supplements (The CINS Trial): A Randomized Controlled, Multicenter Trial Comparing a Brief Intervention with Additional Cognitive Behavioral Therapy, Seal Oil, and Soy Oil for Sick-Listed Low Back Pain Patients The Research Council of Norway, the GC Rieber Funds and Mills DA funds were received in support of this work.

Gait is recognized as a key item related to mental function. Anomalous gait in psychotic individuals has been described for the lower extremities, whereas irregularities for upper body dynamics are not described, explained or verified with unbiased methods. Reduced walking velocity and increased somatic tension defined in this patient category may influence upper body dynamics during gait. The aim of this pilot-study was to describe upper body kinematics and investigate the biomechanical association with walking velocity and muscle tension. Twelve inpatients in a psychiatric ward with first-episode psychosis and 18 healthy control subjects walked at different self-chosen velocities. Movement and walking velocity were registered, and 3D kinematics was analysed for thorax and shoulder joint. Time-synchronized EMG from the trapezius muscle, chosen as indicator for general somatic tension, was analysed for maximal amplitude and variability. Results showed that patients walked with reduced arm swing at the shoulder joint and increased lateral thorax movements. Thorax rotations about the vertical axis, walking velocity and EMG measures were similar in patients and healthy subjects. The present study could not provide a biomechanical explanation for kinematic findings based on walking velocity or somatic tension.

Palliative Medicine Unit,Department of Oncology, St Olav University Hospital, Trondheim, NorwayBackground: Brief treatments for chronic non-malignantpain patients with problematicopioidusearewarranted.The aims of the present study were to investigate (1)whether it is possible to withdraw codeine use in suchpatients with a brief cognitive-behavioural therapy (CBT),(2) whether this could be done without pain escalation andreduction in quality of life and (3) to explore the effects ofcodeine reduction on neurocognitive functioning.Methods: Eleven patients using codeine daily correspond-ing to 40–100mg morphine were included. Two specificallytrained physicians treated the patients with six CBT ses-sions, tapering codeine gradually within 8 weeks. Codeineuse, pain intensity, quality of life and neuropsychologicalfunctioning were assessed at pre-treatment to the 3-monthfollow-up.Results: Codeine use was significantly reduced from mean237mg [standard deviation (SD) 65] pre-treatment to 45mg(SD 66) post-treatment and to 48mg (SD 65) at follow-upwithout significant pain escalation or reductions in qualityof life. Moreover, neuropsychological functioning im-proved significantly on some tests, while others remainedunchanged.Conclusion: The promising findings of codeine reductionin this weaning therapy programme for pain patients withproblematic opioid use should be further evaluated in alarger randomized control trial comparing this brief CBTwith both another brief treatment and attention placebocondition.

Contains fulltext : 118536.pdf (Publisher’s version ) (Open Access) BACKGROUND: Internet-based interventions using cognitive behavioral approaches can be effective in promoting self-management of chronic pain conditions. Web-based programs delivered via smartphones are increasingly used to support the self-management of various health disorders, but research on smartphone interventions for persons with chronic pain is limited. OBJECTIVE: The aim of this trial was to study the efficacy of a 4-week smartphone-delivered intervention with written diaries and therapist feedback following an inpatient chronic pain rehabilitation program. METHODS: A total of 140 women with chronic widespread pain who participated in a 4-week inpatient rehabilitation program were randomized into 2 groups: with or without a smartphone intervention after the rehabilitation. The smartphone intervention consisted of 1 face-to-face session and 4 weeks of written communication via a smartphone. Participants received 3 smartphone diary entries daily to support their awareness of and reflection on pain-related thoughts, feelings, and activities. The registered diaries were immediately available to a therapist who submitted personalized written feedback daily based on cognitive behavioral principles. Both groups were given access to a noninteractive website after discharge to promote constructive self-management. Outcomes were measured with self-reported questionnaires. The primary outcome measure of catastrophizing was determined using the pain catastrophizing scale (score range 0-52). Secondary outcomes included acceptance of pain, emotional distress, functioning, and symptom levels. RESULTS: Of the 140 participants, 112 completed the study: 48 in the intervention group and 64 in the control group. Immediately after the intervention period, the intervention group reported less catastrophizing (mean 9.20, SD 5.85) than the control group (mean 15.71, SD 9.11, P

The objective of this study was to test if and how self-administered practice of relaxation techniques, positive affirmation and guided imagery, in the final part of pregnancy had an impact on giving birth. Further to see if the use of a simple method, a CD with a booklet, with no previous training or specific support of the participants (neither required nor delivered), affected the birth experience. Outcome measures were monitored both during and after delivery: During delivery, pain and anxiety were measured at different stages of birth. Post-delivery Wellbeing (Edmonton Scale 0-10, where 10 is the worst possible feeling of Wellbeing), pain, anxiety, Apgar score, duration of birth, complications and anesthesia/analgesic were recorded. Those in the CD-intervention group also reported how many times they had practiced the techniques. The study employed a randomized controlled trial. Results show that the CD-intervention group had a significantly better score on total Wellbeing, as measured by the ESAS (0-10) Edmonton Scale.

Objective: This systematic review aimed to determine the effectiveness of psychoeducation, cognitive behavioural therapy (CBT) and social support interventions used in the rehabilitation of breast cancer (BC) patients. Methods: We conducted a systematic literature search to identify randomised controlled trials of female BC patients who underwent different psychosocial interventions during or after primary cancer treatment. The methodological quality of all studies was independently assessed by two reviewers. Studies with low quality, less than 20 participants in each group, patients with metastatic cancer, data not presented separately for BC and studies that included other cancer types were excluded. Results: Among 9617 identified studies, only 18 RCTs published between 1999 and 2008, including 3272 patients were finally included in this systematic evaluation. Outcome measures were categorised into quality of life (QoL), fatigue, mood, health behaviour and social function. Six trials examined psychoeducation had inconsistent results, both during and after the primary treatment. Seven trials examined the effect of CBT, four of which given after primary treatment (range 6–12 weeks) demonstrated improvements in QoL; the other three CBT studies given during primary treatment (range 9–20 weeks) had inconsistencies. Five studies addressed social support and showed no conclusive impacts of this intervention. Conclusions: Limited documentation exists on the efficacy of psychosocial rehabilitation interventions among BC patients. However, we found that patients might have QoL benefits from CBT given after primary BC treatment. More documentation is needed regarding the effects of CBT during primary treatment and the effects of psychoeducation and social support. Copyright © 2010 John Wiley & Sons, Ltd.

Aims: To examine whether there are any differences in sickness absenteeism between children in outdoor day care centres and regular day care centres and also to investigate whether other variables predict sickness absenteeism. Methods: Data on sickness absence during a 4-week period together with several explanatory variables of 531 children in 32 regular and 37 outdoor day care centres were collected and included in the analysis. The data were analysed by generalized linear modelling. Results: The overall frequency of sickness absence was 5.1%. There was no general significant difference between sickness absenteeism in regular and outdoor day care centres. Of the other possible explanatory variables only two were found to contribute significantly: age, with a negative relationship, and the interaction effect of a child with a chronic disease or disability going to an outdoor day care centre, with a positive relationship. Conclusions: The present study indicates that sickness absenteeism of a child without a chronic disease or disability is not affected by whether the child attends a regular or an outdoor day care centre. There seem to be no health benefits for children with chronic diseases or disabilities to attend outdoor day care centres — there is in fact evidence that sickness absence for those children is higher in outdoor centres.

Background: Evaluation of posture is a useful tool to measure outcome following therapeutic interventions or to monitor the disease progress and provide information about physical and cognitive status. Traditionally, postural control has been examined by measuring migration of centre of pressure (COP) during a balance task. Recently, structural analysis has been proposed which decomposing the COP trajectory into a unique supraspinal component (rambling) and a spinal reflex component (trembling). There is a great symptom overlap (70%) between fibromyalgia syndrome (FMS) and chronic fatigue syndrome (CFS) and it is questioned whether this is an effect of comorbidity of different syndromes or differing expressions of the same syndrome. Impaired postural control has been reported in participants with FMS compared with healthy controls (HC), and CFS compared with healthy group, but to the best of our knowledge no one has compared postural control in FMS and CFS. Purpose: To investigate the effect of modulation of visual and kinaesthetic information during quiet standing using structural analysis of the CoP signal, in order to explore how CFS and FMS affect postural control and if these expressions differ from healthy individuals along the spectra frommainly pain to mainly fatigue. Methods: Eighty one subjects (CFS, FMS and HC, 27 in each group), age 19–49 years, performed 60 s of quiet standing for each of three conditions

Objective : The effectiveness of an attention distracting and an attention focusing guided imagery as well as the effect of amitriptyline on fibromyalgic pain was studied prospectively. Methods : Fifty-five women with previously diagnosed fibromyalgia were monitored for daily pain (VAS) in a randomized, controlled clinical trial. One group received relaxation training and guided instruction in “pleasant imagery” (PI) in order to distract from the pain experience ( n =17). Another group received relaxation training and attention imagery upon the “active workings of the internal pain control systems”, “attention imagery” (AI) ( n =21). The control group (CG) received treatment as usual ( n =17). Patients were also randomly assigned to 50-mg amitriptyline/day or placebo. Some psychological and socio-demographic variables were also measured initially. The slopes of diary pain ratings over a 4-week period were used as the outcome measures. Results : We found significant differences of the pain-slopes between the three psychological conditions ( P =0.0001). The pleasant imagery ( P attention imagery group’s slope, declined significantly when compared with the control group ( P >0.05). There was neither a difference between the amitriptyline and placebo slopes (main effects, P =0.98) nor a significant amitriptyline × psychological interaction ( P =0.76). Conclusion : Pleasant imagery (PI) was an effective intervention in reducing fibromyalgic pain during the 28-day study period. Amitriptyline had no significant advantage over placebo during the study period.

Web-based interventions may also be effective in enhancing self-management for individuals with chronic pain, but little is known about long-term effects. Research on Web-based interventions to support self-management following participation in pain management programs is limited. OBJECTIVE: The aim is to examine the long-term effects of a 4-week smartphone-intervention with diaries and therapist-written feedback following an inpatient chronic pain rehabilitation program, previously found to be effective at short-term and 5-month follow-ups. METHODS: 140 women with chronic widespread pain, participating in a 4-week inpatient rehabilitation program, were randomized into two groups: with or without a smartphone intervention after the rehabilitation. The smartphone intervention consisted of one face-to-face individual session and 4 weeks of written communication via a smartphone, consisting of three diaries daily to elicit pain-related thoughts, feelings, and activities, as well as daily personalized written feedback based on cognitive behavioral principles from a therapist. Both groups were given access to an informational website to promote constructive self-management. Outcomes were measured with self-reported paper-and-pencil format questionnaires with catastrophizing as the primary outcome measure. Secondary outcomes included daily functioning and symptom levels, acceptance of pain, and emotional distress. RESULTS: By the 11-month follow-up, the favorable between-group differences previously reported post-intervention and at 5-month follow-up on catastrophizing, acceptance, functioning, and symptom level were no longer evident (P>.10). However, there was more improvement in catastrophizing scores during the follow-up period in the intervention group (M=-2.36, SD 8.41) compared to the control group (M=.40, SD 7.20), P=.045. Also, per protocol within-group analysis showed a small positive effect (Cohen's d=.33) on catastrophizing in the intervention group (P=.04) and no change in the control group from the smartphone intervention baseline to 11-month follow-up. A positive effect (Cohen's d=.73) on acceptance was found within the intervention group (P

The pain-reducing effects of paralgin forte (under double-blind conditions) were studied under 3 different experimental conditions: 1) neutral instructions; subjects were given some information about the kind of unpleasant experience/pain involved in the experiment, 2) positive instructions; subjects were informed that the experiment did not involve painful experiences, and 3) negative instructions; subjects were informed that the experiment involved relatively severe pain. Both positive and negative instructions produced significant pain-reducing effects. With regards to paralgin forte, neither pain-reducing effects nor significant differences between paralgin forte and placebo were found. There was no interaction effect between drug and instruction variables. It is concluded that the instruction factors were effective in pain reduction in this experiment.
