An umbrella review of the literature on the effectiveness of psychological interventions for pain reduction

Acceptance and Commitment Therapy for Chronic Pain: An Overview of Systematic Reviews with Meta-Analysis of Randomized Clinical Trials

This overview of reviews aimed to summarize the evidence from systematic reviews and meta-analyses of randomized clinical trials of the efficacy of acceptance and commitment therapy (ACT) for adults with chronic pain in relation to pain intensity, pain-related functioning, quality of life, and psychological factors. The Cumulative Index of Nursing and Allied Health Literature (CINAHL), Embase, PsycINFO, PubMed, and the Cochrane Library databases were searched from inception to July 2, 2023. AMSTAR 2 was used to assess the methodological quality of systematic reviews. The overlap among reviews was calculated. Nine reviews comprising 84 meta-analyses of interest were included. At post-treatment, some meta-analyses mainly showed that ACT can reduce depression symptoms, anxiety symptoms, psychological inflexibility, and pain catastrophizing; and can improve mindfulness, pain acceptance, and psychological flexibility. At three-month follow-up, ACT can reduce depression symptoms and psychological inflexibility, as well as improve pain-related functioning and psychological flexibility. At six-month follow-up, ACT can improve mindfulness, pain-related functioning, pain acceptance, psychological flexibility, and quality of life. At six-twelve-month follow-up, ACT can reduce pain catastrophizing and can improve pain-related functioning. Some methodological and clinical issues are identified in the reviews, such as a very high overlap between systematic reviews, the fact that the certainty of the evidence is often not rated and specific details needed to replicate the interventions reviewed are often not reported. Overall, however, randomized clinical trials and systematic reviews show that ACT can improve outcomes related to chronic pain (eg, pain-related functioning). Future systematic reviews should address the methodological and clinical concerns identified here to produce higher-quality findings. PERSPECTIVE: Despite certain methodological and clinical issues, randomized clinical trials and systematic reviews of ACT appear to show that it can improve outcomes related to chronic pain (eg, psychological factors).

Ultra-processed food exposure and adverse health outcomes: umbrella review of epidemiological meta-analyses

OBJECTIVE

To evaluate the existing meta-analytic evidence of associations between exposure to ultra-processed foods, as defined by the Nova food classification system, and adverse health outcomes.

DESIGN

Systematic umbrella review of existing meta-analyses.

DATA SOURCES

MEDLINE, PsycINFO, Embase, and the Cochrane Database of Systematic Reviews, as well as manual searches of reference lists from 2009 to June 2023.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Systematic reviews and meta-analyses of cohort, case-control, and/or cross sectional study designs. To evaluate the credibility of evidence, pre-specified evidence classification criteria were applied, graded as convincing ("class I"), highly suggestive ("class II"), suggestive ("class III"), weak ("class IV"), or no evidence ("class V"). The quality of evidence was assessed using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) framework, categorised as "high," "moderate," "low," or "very low" quality.

RESULTS

The search identified 45 unique pooled analyses, including 13 dose-response associations and 32 non-dose-response associations (n=9 888 373). Overall, direct associations were found between exposure to ultra-processed foods and 32 (71%) health parameters spanning mortality, cancer, and mental, respiratory, cardiovascular, gastrointestinal, and metabolic health outcomes. Based on the pre-specified evidence classification criteria, convincing evidence (class I) supported direct associations between greater ultra-processed food exposure and higher risks of incident cardiovascular disease related mortality (risk ratio 1.50, 95% confidence interval 1.37 to 1.63; GRADE=very low) and type 2 diabetes (dose-response risk ratio 1.12, 1.11 to 1.13; moderate), as well as higher risks of prevalent anxiety outcomes (odds ratio 1.48, 1.37 to 1.59; low) and combined common mental disorder outcomes (odds ratio 1.53, 1.43 to 1.63; low). Highly suggestive (class II) evidence indicated that greater exposure to ultra-processed foods was directly associated with higher risks of incident all cause mortality (risk ratio 1.21, 1.15 to 1.27; low), heart disease related mortality (hazard ratio 1.66, 1.51 to 1.84; low), type 2 diabetes (odds ratio 1.40, 1.23 to 1.59; very low), and depressive outcomes (hazard ratio 1.22, 1.16 to 1.28; low), together with higher risks of prevalent adverse sleep related outcomes (odds ratio 1.41, 1.24 to 1.61; low), wheezing (risk ratio 1.40, 1.27 to 1.55; low), and obesity (odds ratio 1.55, 1.36 to 1.77; low). Of the remaining 34 pooled analyses, 21 were graded as suggestive or weak strength (class III-IV) and 13 were graded as no evidence (class V). Overall, using the GRADE framework, 22 pooled analyses were rated as low quality, with 19 rated as very low quality and four rated as moderate quality.

CONCLUSIONS

Greater exposure to ultra-processed food was associated with a higher risk of adverse health outcomes, especially cardiometabolic, common mental disorder, and mortality outcomes. These findings provide a rationale to develop and evaluate the effectiveness of using population based and public health measures to target and reduce dietary exposure to ultra-processed foods for improved human health. They also inform and provide support for urgent mechanistic research.

Fibromyalgia and risk of all-cause, specific mortality: A meta-analysis of observational studies

OBJECTIVES

To evaluate the risk of all-cause, specific mortality among patients with fibromyalgia, which is a controversial topic.

METHODS

We conducted a thorough search for cohort studies across the PubMed, Cochrane Library, and Embase databases, from their inception to 1 March 2023, using medical subject headings and relevant keywords. All data were meticulously analyzed using Stata statistical software version 16.0. The protocol was registered on PROSPERO (CRD42023402337).

RESULTS

After analyzing seven cohort studies involving 152 933 individuals published between 2001 and 2020, we found no clear evidence linking fibromyalgia or widespread pain to all-cause mortality risk (odds ratio [OR] 1.11, 95% confidence interval [CI] 0.81-1.53; I2  = 82.6%, p = .505). However, our subgroup analysis revealed that the risk of suicide was significantly higher in fibromyalgia patients compared with non-fibromyalgia patients (OR 5.39, 95% CI 2.16-13.43; I2  = 69.9%, p < .05).

CONCLUSIONS

Our research did not discover any proof indicating a link between fibromyalgia or widespread pain and all-cause mortality. However, it is worth noting that there may be a potential correlation between individuals with fibromyalgia or widespread pain and a higher likelihood of suicide. As we had a limited number of participants in our study, further research is necessary to thoroughly investigate the relationship between these factors.

Risk factors for human papillomavirus infection, cervical intraepithelial neoplasia and cervical cancer: an umbrella review and follow-up Mendelian randomisation studies

BACKGROUND

Persistent infection by oncogenic human papillomavirus (HPV) is necessary although not sufficient for development of cervical cancer. Behavioural, environmental, or comorbid exposures may promote or protect against malignant transformation. Randomised evidence is limited and the validity of observational studies describing these associations remains unclear.

METHODS

In this umbrella review, we searched electronic databases to identify meta-analyses of observational studies that evaluated risk or protective factors and the incidence of HPV infection, cervical intra-epithelial neoplasia (CIN), cervical cancer incidence and mortality. Following re-analysis, evidence was classified and graded based on a pre-defined set of statistical criteria. Quality was assessed with AMSTAR-2. For all associations graded as weak evidence or above, with available genetic instruments, we also performed Mendelian randomisation to examine the potential causal effect of modifiable exposures with risk of cervical cancer. The protocol for this study was registered on PROSPERO (CRD42020189995).

RESULTS

We included 171 meta-analyses of different exposure contrasts from 50 studies. Systemic immunosuppression including HIV infection (RR = 2.20 (95% CI = 1.89-2.54)) and immunosuppressive medications for inflammatory bowel disease (RR = 1.33 (95% CI = 1.27-1.39)), as well as an altered vaginal microbiome (RR = 1.59 (95% CI = 1.40-1.81)), were supported by strong and highly suggestive evidence for an association with HPV persistence, CIN or cervical cancer. Smoking, number of sexual partners and young age at first pregnancy were supported by highly suggestive evidence and confirmed by Mendelian randomisation.

CONCLUSIONS

Our main analysis supported the association of systemic (HIV infection, immunosuppressive medications) and local immunosuppression (altered vaginal microbiota) with increased risk for worse HPV and cervical disease outcomes. Mendelian randomisation confirmed the link for genetically predicted lifetime smoking index, and young age at first pregnancy with cervical cancer, highlighting also that observational evidence can hide different inherent biases. This evidence strengthens the need for more frequent HPV screening in people with immunosuppression, further investigation of the vaginal microbiome and access to sexual health services.

Impact of mental disorders on clinical outcomes of physical diseases: an umbrella review assessing population attributable fraction and generalized impact fraction

Empirical evidence indicates a significant bidirectional association between mental disorders and physical diseases, but the prospective impact of men-tal disorders on clinical outcomes of physical diseases has not been comprehensively outlined. In this PRISMA- and COSMOS-E-compliant umbrella review, we searched PubMed, PsycINFO, Embase, and Joanna Briggs Institute Database of Systematic Reviews and Implementation Reports, up to March 15, 2022, to identify systematic reviews with meta-analysis that examined the prospective association between any mental disorder and clinical outcomes of physical diseases. Primary outcomes were disease-specific mortality and all-cause mortality. Secondary outcomes were disease-specific incidence, functioning and/or disability, symptom severity, quality of life, recurrence or progression, major cardiac events, and treatment-related outcomes. Additional inclusion criteria were further applied to primary studies. Random effect models were employed, along with I² statistic, 95% prediction intervals, small-study effects test, excess significance bias test, and risk of bias (ROBIS) assessment. Associations were classified into five credibility classes of evidence (I to IV and non-significant) according to established criteria, complemented by sensitivity and subgroup analyses to examine the robustness of the main analysis. Statistical analysis was performed using a new package for conducting umbrella reviews (https://metaumbrella.org). Population attributable fraction (PAF) and generalized impact fraction (GIF) were then calculated for class I-III associations. Forty-seven systematic reviews with meta-analysis, encompassing 251 non-overlapping primary studies and reporting 74 associations, were included (68% were at low risk of bias at the ROBIS assessment). Altogether, 43 primary outcomes (disease-specific mortality: n=17; all-cause mortality: n=26) and 31 secondary outcomes were investigated. Although 72% of associations were statistically significant (p<0.05), only two showed convincing (class I) evidence: that between depressive disorders and all-cause mortality in patients with heart failure (hazard ratio, HR=1.44, 95% CI: 1.26-1.65), and that between schizophrenia and cardiovascular mortality in patients with cardiovascular diseases (risk ratio, RR=1.54, 95% CI: 1.36-1.75). Six associations showed highly suggestive (class II) evidence: those between depressive disorders and all-cause mortality in patients with diabetes mellitus (HR=2.84, 95% CI: 2.00-4.03) and with kidney failure (HR=1.41, 95% CI: 1.31-1.51); that between depressive disorders and major cardiac events in patients with myocardial infarction (odds ratio, OR=1.52, 95% CI: 1.36-1.70); that between depressive disorders and dementia in patients with diabetes mellitus (HR=2.11, 95% CI: 1.77-2.52); that between alcohol use disorder and decompensated liver cirrhosis in patients with hepatitis C (RR=3.15, 95% CI: 2.87-3.46); and that between schizophrenia and cancer mortality in patients with cancer (standardized mean ratio, SMR=1.74, 95% CI: 1.41-2.15). Sensitivity/subgroup analyses confirmed these results. The largest PAFs were 30.56% (95% CI: 27.67-33.49) for alcohol use disorder and decompensated liver cirrhosis in patients with hepatitis C, 26.81% (95% CI: 16.61-37.67) for depressive disorders and all-cause mortality in patients with diabetes mellitus, 13.68% (95% CI: 9.87-17.58) for depressive disorders and major cardiac events in patients with myocardial infarction, 11.99% (95% CI: 8.29-15.84) for schizophrenia and cardiovascular mortality in patients with cardiovascular diseases, and 11.59% (95% CI: 9.09-14.14) for depressive disorders and all-cause mortality in patients with kidney failure. The GIFs confirmed the preventive capacity of these associations. This umbrella review demonstrates that mental disorders increase the risk of a poor clinical outcome in several physical diseases. Prevention targeting mental disorders - particularly alcohol use disorders, depressive disorders, and schizophrenia - can reduce the incidence of adverse clinical outcomes in people with physical diseases. These findings can inform clinical practice and trans-speciality preventive approaches cutting across psychiatric and somatic medicine.

A proof-of-concept randomized controlled trial of follow-up mental health care for traumatic injury patients following hospital discharge

INTRODUCTION

Traumatic injuries account for a huge burden of disease. Many patients develop persistent mental health problems in the months following hospital discharge. This proof-of-concept trial investigated whether Stepped Care comprising follow-up assessment telephone calls and appropriate referral information would lead to better mental health and functioning in traumatic injury patients.

METHODS

Patients admitted to the Trauma Service at Royal North Shore Hospital were randomized to either Stepped Care (n = 84) or Treatment as Usual (n = 90). All patients were assessed for anxiety, depression, and posttraumatic stress prior to hospital discharge. Those in Stepped Care received a telephone call at 1-month and 3-months after hospital discharge in which they were administered a brief assessment; patients who reported mental health or pain difficulties were provided with information for local specialists to address their specific problem. All patients were independently assessed by telephone interview 9- months after hospital discharge for posttraumatic stress disorder (PTSD) (primary outcome), as well as for anxiety, depression, disability, and pain.

RESULTS

There were 58 (73%) patients that could be contacted at either the 1-month or 3-month assessments. Of those contacted, 28 patients (48% of those contacted) were referred for specialist assistance. There were no differences between treatment arms on PTSD symptoms at follow-up [F_1,95 = 0.55, p = 0.46]. At the 9-month assessment, patients in the Stepped Care condition reported significantly less anxiety [F_1,95 = 5.07, p = 0.03] and disability [F_1,95 = 4.37, p = 0.04] relative to those in Treatment as Usual. At 9 months there was no difference between conditions on depression [F_1,95 = 1.03, p = 0.31]. There were no differences between conditions on self-reported pain difficulties.

CONCLUSIONS

This proof-of-concept trial suggests that brief screening assessments of traumatic injury patients following hospital discharge, combined with appropriate referral information, may lead to better functional outcomes. Further research is needed with larger sample sizes and greater verification of referral uptake to validate this finding.

The clinician's guide to prevention and treatment of osteoporosis

Osteoporosis is the most common metabolic bone disease in the USA and the world. It is a subclinical condition until complicated by fracture(s). These fractures place an enormous medical and personal burden on individuals who suffer from them and take a significant economic toll. Any new fracture in an adult aged 50 years or older signifies imminent elevated risk for subsequent fractures, particularly in the year following the initial fracture. What a patient perceives as an unfortunate accident may be seen as a sentinel event indicative of bone fragility and increased future fracture risk even when the result of considerable trauma. Clinical or subclinical vertebral fractures, the most common type of osteoporotic fractures, are associated with a 5-fold increased risk for additional vertebral fractures and a 2- to 3-fold increased risk for fractures at other sites. Untreated osteoporosis can lead to a vicious cycle of recurrent fracture(s), often resulting in disability and premature death. In appropriate patients, treatment with effective antifracture medication prevents fractures and improves outcomes. Primary care providers and medical specialists are critical gatekeepers who can identify fractures and initiate proven osteoporosis interventions. Osteoporosis detection, diagnosis, and treatment should be routine practice in all adult healthcare settings. The Bone Health and Osteoporosis Foundation (BHOF) - formerly the National Osteoporosis Foundation - first published the Clinician's Guide in 1999 to provide accurate information on osteoporosis prevention and treatment. Since that time, significant improvements have been made in diagnostic technologies and treatments for osteoporosis. Despite these advances, a disturbing gap persists in patient care. At-risk patients are often not screened to establish fracture probability and not educated about fracture prevention. Most concerning, the majority of highest risk women and men who have a fracture(s) are not diagnosed and do not receive effective, FDA-approved therapies. Even those prescribed appropriate therapy are unlikely to take the medication as prescribed. The Clinician's Guide offers concise recommendations regarding prevention, risk assessment, diagnosis, and treatment of osteoporosis in postmenopausal women and men aged 50 years and older. It includes indications for bone densitometry as well as fracture risk thresholds for pharmacologic intervention. Current medications build bone and/or decrease bone breakdown and dramatically reduce incident fractures. All antifracture therapeutics treat but do not cure the disease. Skeletal deterioration resumes sooner or later when a medication is discontinued-sooner for nonbisphosphonates and later for bisphosphonates. Even if normal BMD is achieved, osteoporosis and elevated risk for fracture are still present. The diagnosis of osteoporosis persists even if subsequent DXA T-scores are above - 2.5. Ongoing monitoring and strategic interventions will be necessary if fractures are to be avoided. In addition to pharmacotherapy, adequate intake of calcium and vitamin D, avoidance of smoking and excessive alcohol intake, weight-bearing and resistance-training exercise, and fall prevention are included in the fracture prevention armamentarium. Where possible, recommendations in this guide are based on evidence from RCTs; however, relevant published data and guidance from expert clinical experience provides the basis for recommendations in those areas where RCT evidence is currently deficient or not applicable to the many osteoporosis patients not considered for RCT participation due to age and morbidity.

Effect of statins on risk and mortality of urologic malignancies: Protocol of an umbrella review

Introduction

Urologic malignancies are the major causes of morbidity and mortality in men over 40 years old, accounting for more than 20% of all malignant tumors. Several meta-analyses are shown that statin exposure can reduce the morbidity and mortality of various urologic cancers. The adjuvant roles of statin in tumor prevention and anti-tumor activity are now being gradually recognized and have gained attention. Nevertheless, to date, multiple clinical studies and meta-analyses found inconsistent results of their anti-cancer effects. This study aims to evaluate the credibility of the published systematic reviews and meta-analyses that assessed the effects of statin exposure for the incidence and mortality of urologic cancers through an umbrella review.

Methods and analysis

The guidance of overviews of systematic reviews reported in the Cochrane Handbook for Systematic Reviews of interventions will be followed while performing and reporting this umbrella review. This project was registered in PROSPERO with the registration number of CRD42020208854. PubMed, Embase and Cochrane Library will be searched for systematic reviews to identify and appraise systematic reviews or meta-analyses of interventional and observational studies examining statin use and the risks of urologic cancer incidence and mortality without language restriction. The search will be carried out on 10 February 2022. Systematic reviews based on qualitative, quantitative or mixed-methods studies will be involved and critically evaluated by two authors using the Assessment of Multiple Systematic Reviews 2 (AMSTAR2, an updated version of AMSTAR) tool. We will determine the level of evidence using the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) tool. The summary effect estimates will be calculated using random-effects models. Between- study heterogeneity will be assessed using the I² statistic. Furthermore, we will also assess the evidence of excess significance bias and evidence of small study effects.

Ethics and dissemination

Ethics approval is not required as we will search and gather data based on the published systematic reviews and meta-analyses. We plan to publish the results of this umbrella review in a peer-reviewed journal and will be presented at a urological disease conference. All the relevant additional data will also be uploaded to the online open access databases.

Cognitive behavioral therapy with and without biofeedback in fibromyalgia: Assessment of functional and clinical change

The study compared the effectiveness of Cognitive Behavioral Therapy (CBT) with biofeedback or with emotional expression in individuals with fibromyalgia, and a waiting list control group. 88 women participated in a naturalistic study with random assignment. The Fibromyalgia Impact Questionnaire, SCL-90R, and a visual analog quality of life scale were used. Both intervention groups improved, but differed in physical and emotional control response. Using the reliable change index procedure, clinical improvement occurred in 18.8% of participants, and 4.8% achieved scores comparable with clinical recovery. Greater specificity on therapeutic objectives is warranted.

Therapeutic interventions for childhood cancer: An umbrella review of randomized evidence

Treatment advancements in pediatric cancer have improved prognosis, but the strength of supporting evidence has not been thoroughly evaluated. To critically appraise it, we performed an umbrella review of meta-analyses of randomized controlled trials examining the efficacy and safety of therapeutic interventions for pediatric malignancies. Fourteen publications (68 meta-analyses, 31,496 participants) were eligible. Acute lymphoblastic leukemia (ALL) was investigated at most. Substantial heterogeneity was detected in 10 associations, with limited indications for small-study effects and excess-significance bias. The most concrete evidence pertained to the use of methotrexate and vincristine-prednisone pulses for ALL, improving event-free survival. Evidence regarding other cancers was relatively weak. Conclusively, we found few small meta-analyses focusing mainly on ALL. Randomized evidence stemming from adult populations still seems to serve as valuable indirect evidence backup. More randomized evidence and individual patient data meta-analyses are needed to increase certainty and precision in the care of pediatric cancer patients.

Surgical treatment for cryptoglandular and Crohn's perianal fistulas: Protocol of an umbrella review

Introduction

A high prevalence of cryptoglandular and Crohn’s perianal fistulas has been reported worldwide, and several surgical options are available for the management of anal fistula, with varying clinical efficacy. However, currently, the available evidence for the effectiveness of these surgical approaches are lacking and of concern in terms of the credibility and strength. The purpose of this study is to evaluate the credibility of the published systematic reviews and meta-analyses that assess the efficacy and safety of the surgical options for cryptoglandular and Crohn’s perianal fistulas through an umbrella review.

Methods and analysis

A systematic search in PubMed, Embase and Cochrane library will be performed from inception to December 2020 without any language restriction. We will include systematic reviews and meta-analyses that investigate the efficacy and safety of surgical approaches in the management of cryptoglandular and Crohn’s perianal fistulas. Two reviewers will independently screen search results through reading the titles or abstracts. Relevant information will be extracted from each eligible systematic review or meta-analysis. Based on random effects model summary estimates along with their p values, 95% prediction intervals, between-study heterogeneity, small-study effects and excess significance, we will classify the evidence from convincing (class I) to weak (class IV). Findings will be summarized using quantitative synthesis combined with a narrative approach. Cryptoglandular and Crohn’s perianal fistulas will be summarized separately. Two authors will independently perform the literature search, data extraction, and quality assessment of each included systematic review and meta-analysis. Any unresolved conflicts or doubts will be resolved by discussion or by consulting a senior author. The risk of bias of the systematic reviews will be assessed using a 16-item Assessment of Multiple Systematic Reviews 2 (AMSTAR2) checklist. The strength of evidence for the included systematic reviews will be classified as "high", "moderate", "low", or "critically low" quality.

Ethics and dissemination

Ethics approval is not required as we will collect data from the published systematic reviews and meta-analyses without using individual patient data. The results of this umbrella review will be published in a peer-reviewed journal and will be presented at an anorectal disease conference.

Comparison of postoperative complications between open and laparoscopic appendectomy: An umbrella review of systematic reviews and meta-analyses

BACKGROUND

Laparoscopic appendectomy (LA) has been popular for decades because of shorter hospitalization and return to routine activity. However, complications (e.g., surgical site infection [SSI] and intra-abdominal abscess [IAA]) relative to open appendectomy (OA) are still debated. We therefore conducted an umbrella review to systematically appraise meta-analyses (MAs) comparing SSI and IAA between LA and OA.

METHODS

Meta-analyses that included only randomized controlled trials were identified from MEDLINE and Scopus databases from inception until July 2018. Their findings were described, the number of overlapping studies was assessed using corrected covered area, and excess significant tests were also assessed. Finally, effect sizes of SSI and IAA were repooled.

RESULTS

Ten MAs were eligible; SSI was reported in all MAs and IAA in 8 MAs. Surgical site infection rate was 48% to 70% lower in LA than OA, but conversely, IAA rate was 1.34 to 2.20 higher in LA than OA. Overlapping included studies for SSI and IAA were 61% and 54%, respectively, indicating that less information was added across MAs. However, there was no evidence of bias from excess significant tests when pooling SSI or IAA estimates. The risk ratios (95% confidence interval) comparing LA versus OA were repooled in adults and children yielding risk ratios of 0.56 (0.47-0.67) and 0.40 (0.25-0.65) for SSI, and 1.20 (0.88-1.63) and 1.05 (0.61-1.80) for IAA.

CONCLUSION

Evidence from this umbrella review indicates that LA carries a significantly lower risk of SSI but likely a higher risk of IAA than OA.

From research to clinical practice: a systematic review of the implementation of psychological interventions for chronic headache in adults

BACKGROUND

Psychological interventions have been proved to be effective in chronic headache (CH) in adults. Nevertheless, no data exist about their actual implementation into standard clinical settings. We aimed at critically depicting the current application of psychological interventions for CH into standard care exploring barriers and facilitators to their implementation. Secondarily, main outcomes of the most recent psychological interventions for CH in adults have been summarized.

METHODS

We conducted a systematic review through PubMed and PsycINFO in the time range 2008-2018. A quality analysis according to the QATSDD tool and a narrative synthesis were performed. We integrated results by: contacting the corresponding author of each paper; exploring the website of the clinical centers cited in the papers.

RESULTS

Of the 938 identified studies, 28 papers were selected, whose quality largely varied with an average %QATSDD quality score of 64.88%. Interventions included CBT (42.85%), multi-disciplinary treatments (22.43%), relaxation training (17.86%), biofeedback (7.14%), or other interventions (10.72%). Treatments duration (1 day-9 months) and intensity varied, with a prevalence of individual-basis implementation. The majority of the studies focused on all primary headaches; 4 studies focused on medication-overuse headache. Most of the studies suggest interventions as effective, with the reduction in frequency of attacks as the most reported outcome (46.43%). Studies were distributed in different countries, with a prevalent and balanced distribution in USA and Europe. Ten researches (35.71%) were performed in academic contexts, 11 (39.28%) in clinical settings, 7 (25%) in pain/headache centres. Interventions providers were professionals with certified experience. Most of the studies were funded with private or public funding. Two contacted authors answered to our e-mail survey, with only one intervention implemented in the routine clinical practice. Only in three out of the 16 available websites a reference to the implementation into the clinical setting was reported.

CONCLUSION

Analysis of contextual barriers/facilitators and cost-effectiveness should be included in future studies, and contents regarding dissemination/implementation of interventions should be incorporated in the professional training of clinical scientists. This can help in filling the gap between the existing published research and treatments actually offered to people with CH.

Laparoendoscopic single-site surgery compared with conventional laparoscopic surgery for benign ovarian masses: a systematic review and meta-analysis

OBJECTIVE

We aimed to evaluate the safety, efficiency and preferred indication for laparoendoscopic single-site surgery (LESS) compared with conventional laparoscopic (CL) surgery for benign ovarian masses.

DESIGN

A systemic review and cumulative meta-analysis were performed in line with the criteria of Grading of Recommendations Assessment, Development and Evaluation: levels of evidence and grades of recommendation.

DATA SOURCES

We comprehensively searched the electronic databases including PubMed, Medline, Embase and the Cochrane Library in November 2018.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included all randomised controlled trials (RCTs) and retrospective studies published in recent 10 years, which investigated the performance of LESS versus CL in patients at all ages with benign ovarian masses.

RESULTS

Four RCTs and nine retrospective studies published in recent decade including 1542 cases (744 cases for LESS and 798 cases for CL) were identified. Perioperative complication was consisted of intraoperative and postoperative complications, including ileus, wound infection or dehiscence and incisional hernia. Although LESS has less postoperative analgesic consumption (46.78% and 79.25%; OR: 0.49; 95% CI: 0.33 to 0.74, p<0.001) and shorter hospital stay (weighted mean difference (WMD): -0.24 days; 95% CI: -0.35 to -0.14; p<0.001), CL has less perioperative complications (6.59% and 2.85%; OR: 2.08; 95% CI: 1.05 to 4.11, p=0.04) and shorter operative time (WMD: 3.43 min; 95% CI: -0.03 to 6.88; p=0.05). Body mass index, history of previous abdominal surgery, size of adnexal mass, estimated blood loss and postoperative pain scores did not differ significantly between two techniques.

CONCLUSIONS

The indications of LESS for benign ovarian masses are similar to CL and it has better postoperative recovery. However, with less perioperative complications, CL surgery is safer than LESS.

Increase value and reduce waste in research on psychological therapies

A seminal Lancet series focused on increasing value and reducing waste in biomedical research, providing a transferrable template to diagnose problems in research. Our goal was to document how some of these sources of waste apply to mental health and particularly psychological treatments research. We synthesize and critically evaluate empirical findings in relation to four major sources: i) defining research priorities; ii) research design, methods and analysis; iii) accessibility of research information; iv) accuracy and usability of research reports. We demonstrate that each source of waste considered is well-represented and amply documented within this field. We describe hype and insufficient consideration of what is known in defining research priorities, persistent risk of bias, particularly due to selective outcome reporting, for psychotherapy trials across mental disorders, intellectual and financial biases, direct and indirect evidence of publication bias, largely inexistent adoption of data sharing, issues of multiplicity and fragmentation of data and findings, and insufficient adoption of reporting guidelines. We expand on a few general solutions, including supporting meta-research, properly testing interventions to increase research quality, placing open science at the center of psychological treatment research and remaining vigilant particularly regarding the strains of research currently prioritized, such as experimental psychopathology.

Couple Interventions for Chronic Pain: A Systematic Review

OBJECTIVE

Couple interventions for chronic pain have been shown to more effectively reduce pain intensity for individuals with chronic pain (ICPs) than individual behavioral interventions or usual care. This systematic review identified randomized controlled trials of couple interventions to highlight strategies that could be incorporated into psychotherapy with ICPs and their romantic partners.

METHODS

The authors identified articles reporting randomized controlled trials of couple interventions for chronic pain. Three databases were searched (ie, PubMed, Embase, and PsycInfo), resulting in 18 studies and 22 articles.

RESULTS

Couple interventions resulted in statistically significant improvements in pain intensity compared with other conditions in 8% to 40% of the studies depending on the comparator group (i.e., control, individual intervention, another couple intervention), and in statistically significant improvements on a pain-related outcome compared with other conditions in 31% to 50% of the studies depending on the comparator group (ie, control, individual intervention, another couple intervention). Educating couples about pain was the most common strategy (83%). Jointly administered relaxation or meditation skills were included in nearly half of the interventions (48%). Many interventions taught cognitive-behavioral skills jointly to couples (39%) or to the ICP with partner encouragement (30%). Teaching couples how to request and provide assistance (30%), and encouraging partners to avoid reinforcing pain behaviors (39%), occurred frequently. ICPs and their partners were often asked to set goals (30%).

DISCUSSION

This review outlined strategies included in couple interventions for chronic pain that are derived from the cognitive-behavioral therapy, acceptance and commitment therapy, and operant behavioral traditions, but delivered relationally. Therapists working with ICPs and their partners may integrate these strategies into their practice to help couples who are managing chronic pain.

A Person-Centred Approach When Encountering Students With Recurrent Pain: School Nurses' Experiences

Stress has a negative impact on students' daily lives and can be associated with recurrent pain. School nurses play a key role in supporting young people with stress-related pain. The purpose of this qualitative interview study was to elucidate school nurses' experiences of encountering students with recurrent pain when practicing person-centred care. The school nurses were based at public and private schools and worked with students aged 12-19. Data were collected through interviews with 18 school nurses and analyzed with deductive content analysis. The school nurses felt that actively listening to the students' narratives about daily life with recurrent pain, and co-creation of a health plan, encouraged the students to participate as partners in their own care and strengthened their relation with the students. The application of a person-centred approach in school health care meant that traditional knowledge transfer was replaced with a dialogue that reflects both the student's and school nurse's perspective.

Psychosocial recommendations for the care of children and adults with epidermolysis bullosa and their family: evidence based guidelines

Epidermolysis Bullosa (EB) is a group of rare genetic disorders resulting in skin fragility and other symptoms. Commissioned by DEBRA International and funded by DEBRA Norway, this evidence-bases guideline provides recommendations to optimise psychosocial wellbeing in EB.

An international multidisciplinary panel of social and health care professionals (HCP) and people living with EB was formed. A systematic international literature review was conducted by the panel following the Scottish Intercollegiate Guidelines Network (SIGN) methodology. The resulting papers underwent systematic selection and critique processes. Included papers were allocated to 6 different outcome groups to allow data synthesis and exploration: quality of life, coping, family, wellbeing, access to HCP and pain. Based on the evidence in those papers, recommendations were made for individuals living with EB, family and caregivers and HCP working in the field.

Few studies have investigated interventions and which factors lead to better outcomes, but general recommendations can be made. EB is a complex disease impacting enormously on every aspect of psychosocial life. People and families living with EB need access to multidisciplinary support, including psychological guidance, in order to improve quality of life and psychosocial wellbeing. Interventions should stimulate social participation to prevent isolation. People with EB and their families should be able to access a supportive network. HCP should be well supported and educated about the complexity of EB. They should work collaboratively with those around the individual with EB (e.g. schools, employers etc.) to provide psychosocial opportunity and care.

Attention should be paid to the psychosocial impact of EB as well as physical needs. Directions for research are indicated.

Psychological treatments for return to work in individuals on sickness absence due to common mental disorders or musculoskeletal disorders: a systematic review and meta-analysis of randomized-controlled trials

Purpose

Common mental disorders (CMDs) and musculoskeletal disorders are highly prevalent in the population and cause significant distress and disability, and high costs to society. The main objective of this systematic review and meta-analysis was to examine the outcome and comparative effectiveness of psychological interventions in reducing sickness absence (SA) due to CMDs or musculoskeletal disorders, compared to a waitlist control group, usual care or another clinical intervention.

Methods

We reviewed 3515 abstracts of randomized controlled trials published from 1998 to 2017. Of these, 30 studies were included in the analysis.

Results

The psychological interventions were overall more effective than treatment as usual in reducing SA (small effect sizes), but not compared to other clinical interventions. Results were similar for studies on CMDs and musculoskeletal pain. A few significant moderating effects were found for treatment-specific variables. However, these were  difficult to interpret as they pointed in different directions.

Conclusion

There was a small but significant effect of psychological treatments in reducing SA. We identified areas of improvement such as methodological problems among the included studies and failure to specifically address RTW in the interventions that were evaluated. Clinical implications of the findings, and ways of improving methodological rigour of future studies are discussed.

Effect of a Positive Psychological Intervention on Pain and Functional Difficulty Among Adults With Osteoarthritis: A Randomized Clinical Trial

IMPORTANCE

Positive psychological interventions for improving health have received increasing attention recently. Evidence on the impact of such interventions on pain, and racial disparities in pain, is limited.

OBJECTIVE

To assess the effects of a positive psychological intervention on pain and functional difficulty in veterans with knee osteoarthritis.

DESIGN, SETTING, AND PARTICIPANTS

The Staying Positive With Arthritis Study is a large, double-blinded randomized clinical trial powered to detect race differences in self-reported pain in response to a positive psychological intervention compared with a neutral control intervention. Data were collected from 2 urban Veterans Affairs medical centers. Participants included non-Hispanic white and non-Hispanic African American patients aged 50 years or older with a diagnosis of osteoarthritis. Mailings were sent to 5111 patients meeting these criteria, of whom 839 were fully screened, 488 were eligible, and 360 were randomized. Enrollment lasted from July 8, 2015, to February 1, 2017, with follow-up through September 6, 2017.

INTERVENTIONS

The intervention comprised a 6-week series of evidence-based activities to build positive psychological skills (eg, gratitude and kindness). The control program comprised similarly structured neutral activities. Programs were delivered via workbook and weekly telephone calls with interventionists.

MAIN OUTCOMES AND MEASURES

The primary outcomes were self-reported pain and functional difficulty measured using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC; range 0-100). Secondary outcomes included affect balance and life satisfaction.

RESULTS

The sample included 180 non-Hispanic white patients and 180 non-Hispanic African American patients (mean [SD] age, 64.2 [8.8] years; 76.4% were male). Mean (SD) baseline scores for WOMAC pain and functional difficulty were 48.8 (17.6) and 46.8 (18.1), respectively. Although both decreased significantly over time (pain: χ23 = 49.50, P < .001; functional difficulty: χ23 = 22.11, P < .001), differences were small and did not vary by treatment group or race. Exploratory analyses suggested that the intervention had counterintuitive effects on secondary outcomes.

CONCLUSIONS AND RELEVANCE

The results of this randomized clinical trial do not support the use of positive psychological interventions as a stand-alone treatment for pain among white or African American veterans with knee osteoarthritis. Adaptations are needed to identify intervention components that resonate with this population, and the additive effect of incorporating positive psychological interventions into more comprehensive pain treatment regimens should be considered.
