IntroductionThe efficacy and the optimal type and volume of aerobic exercise (AE) in fibromyalgia syndrome (FMS) are not established. We therefore assessed the efficacy of different types and volumes of AE in FMS.MethodsThe Cochrane Library, EMBASE, MEDLINE, PsychInfo and SPORTDISCUS (through April 2009) and the reference sections of original studies and systematic reviews on AE in FMS were systematically reviewed. Randomised controlled trials (RCTs) of AE compared with controls (treatment as usual, attention placebo, active therapy) and head-to-head comparisons of different types of AE were included. Two authors independently extracted articles using predefined data fields, including study quality indicators.ResultsTwenty-eight RCTs comparing AE with controls and seven RCTs comparing different types of AE with a total of 2,494 patients were reviewed. Effects were summarised using standardised mean differences (95% confidence intervals) by random effect models. AE reduced pain (-0.31 (-0.46, -0.17); P < 0.001), fatigue (-0.22 (-0.38, -0.05); P = 0.009), depressed mood (-0.32 (-0.53, -0.12); P = 0.002) and limitations of health-related quality of life (HRQOL) (-0.40 (-0.60, -0.20); P < 0.001), and improved physical fitness (0.65 (0.38, 0.95); P < 0.001), post treatment. Pain was significantly reduced post treatment by land-based and water-based AE, exercises with slight to moderate intensity and frequency of two or three times per week. Positive effects on depressed mood, HRQOL and physical fitness could be maintained at follow-up. Continuing exercise was associated with positive outcomes at follow-up. Risks of bias analyses did not change the robustness of the results. Few studies reported a detailed exercise protocol, thus limiting subgroup analyses of different types of exercise.ConclusionsAn aerobic exercise programme for FMS patients should consist of land-based or water-based exercises with slight to moderate intensity two or three times per week for at least 4 weeks. The patient should be motivated to continue exercise after participating in an exercise programme.

Moderate-quality evidence supports the recommendation of yoga as a supportive intervention for improving health-related quality of life and reducing fatigue and sleep disturbances when compared with no therapy, as well as for reducing depression, anxiety and fatigue, when compared with psychosocial/educational interventions. Very low-quality evidence suggests that yoga might be as effective as other exercise interventions and might be used as an alternative to other exercise programmes.

BackgroundMany breast cancer patients and survivors use yoga to cope with their disease. The aim of this review was to systematically assess and meta-analyze the evidence for effects of yoga on health-related quality of life and psychological health in breast cancer patients and survivors.MethodsMEDLINE, PsycInfo, EMBASE, CAMBASE, and the Cochrane Library were screened through February 2012. Randomized controlled trials (RCTs) comparing yoga to controls were analyzed when they assessed health-related quality of life or psychological health in breast cancer patients or survivors. Risk of bias was assessed using the Cochrane risk of bias tool. Standardized mean differences (SMD) and 95% confidence intervals (CI) were calculated.ResultsTwelve RCTs with a total of 742 participants were included. Seven RCTs compared yoga to no treatment; 3 RCTs compared yoga to supportive therapy; 1 RCT compared yoga to health education; and 1 RCT compared a combination of physiotherapy and yoga to physiotherapy alone. Evidence was found for short-term effects on global health-related quality of life (SMD = 0.62 [95% CI: 0.04 to 1.21]; P = 0.04), functional (SMD = 0.30 [95% CI: 0.03 to 0.57), social (SMD = 0.29 [95% CI: 0.08 to 0.50]; P < 0.01), and spiritual well-being (SMD = 0.41 [95% CI: 0.08; 0.74]; P = 0.01). These effects were, however, only present in studies with unclear or high risk of selection bias. Short-term effects on psychological health also were found: anxiety (SMD = −1.51 [95% CI: -2.47; -0.55]; P < 0.01), depression (SMD = −1.59 [95% CI: -2.68 to −0.51]; P < 0.01), perceived stress (SMD = −1.14 [95% CI:-2.16; -0.12]; P = 0.03), and psychological distress (SMD = −0.86 [95% CI:-1.50; -0.22]; P < 0.01). Subgroup analyses revealed evidence of efficacy only for yoga during active cancer treatment but not after completion of active treatment.ConclusionsThis systematic review found evidence for short-term effects of yoga in improving psychological health in breast cancer patients. The short-term effects on health-related quality of life could not be clearly distinguished from bias. Yoga can be recommended as an intervention to improve psychological health during breast cancer treatment.

This meta-analysis revealed evidence for the short-term effectiveness and safety of mindfulness-based interventions in women with breast cancer. However, their clinical relevance remains unclear. Further research is needed.

Objective. To systematically assess the potential association of fibromyalgia syndrome (FMS) with emotional, physical, and sexual abuse. Methods. The databases EMBase, Google Scholar, Medline, and PsycINFO (through April 2010) and the reference sections of original studies were searched for eligible studies. Eligible studies were cohort or case-control studies that assessed at least one type of emotional, physical, or sexual abuse in childhood or adulthood in patients with FMS and in controls. Two authors independently extracted descriptive, quality, and outcome data from included studies. Methodologic quality was assessed by the Newcastle-Ottawa Quality Assessment Scale. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were pooled across studies by using the random-effects model. Heterogeneity was assessed by I 2 ‫؍‬ 64%; 4 studies). Study quality was mostly poor. Low study quality was associated with higher effect sizes for sexual abuse in childhood, but not with other effect sizes. Conclusion. The association of FMS with physical and sexual abuse could be confirmed, but is confounded by study quality.

The aim of this systematic review and meta-analysis was to investigate the effectiveness of exercise for colorectal cancer patients. PubMed/Medline, Scopus and the Cochrane Library were searched through December 2012 without language restrictions. Randomised controlled trials (RCTs) comparing exercise interventions to control conditions were analysed when they assessed health-related quality of life, fatigue, physical fitness, survival and/or tumour-associated biomarkers in colorectal cancer patients. Risk of bias was assessed using the risk of bias tool recommended by the Cochrane Back Review Group. Literature search identified 342 non-duplicate records of which five RCTs with a total of 238 patients were included; three RCTs had low risk of bias. No evidence was found for short-term effects on quality of life [standardised mean difference (SMD) = 0.18; 95% confidence interval (CI) -0.39, 0.76; P = 0.53] or fatigue (SMD = 0.18; 95% CI -0.22, 0.59; P = 0.38). There was strong evidence for short-term improvements of physical fitness after aerobic exercise compared with controls (SMD = 0.59; 95% CI 0.25, 0.93; P < 0.01). One RCT each assessed immune parameters and oxidative DNA damage. No study reported survival rates or safety data. Given this insufficient evidence and the lack of safety data, no recommendation can be made regarding exercise interventions as a routine intervention for colorectal cancer patients.
