Randomized Controlled Trial
The effect of dietary glutamate on fibromyalgia and irritable bowel symptoms.
To examine the effects of a challenge with monosodium glutamate (MSG) as compared to placebo on the symptoms of fibromyalgia (FM), in participants who initially experienced >30% remission of symptoms on an excitotoxin elimination diet. ⋯ These findings suggest that dietary glutamate may be contributing to FM symptoms in some patients. Future research on the role of dietary excitotoxins in FM is warranted.

Comparative Study
Autoimmune rheumatic disease associated symptoms in fibromyalgia patients and their influence on anxiety, depression and somatisation: a comparative study.
In this study we evaluated the frequency of autoimmune rheumatic disease associated major symptoms in fibromyalgia (FM) patients, and the association between their presence and anxiety, depression and somatisation. ⋯ The presence of which findings in FM seems to be associated with anxiety, depression, and somatization rather than ANA positivity and disease severity.

Review Meta Analysis
Placebo and nocebo responses in randomised controlled trials of drugs applying for approval for fibromyalgia syndrome treatment: systematic review and meta-analysis.
The superiority of true drug treatment over placebo in reducing symptoms of fibromyalgia syndrome (FMS) is small and bought by relevant rates of drop-outs due to adverse events. Recent systematic reviews demonstrated that a substantial proportion of the beneficial and adverse effects of true drug is attributable to placebo in chronic pain trials. We determined the magnitude of the placebo and nocebo response and its impact on the benefits and harms of true drug in trials of drugs which were submitted for approval for treatment of FMS. ⋯ The magnitude of placebo and nocebo response in trials of drugs applying for approval for FMS treatment was substantial. Study investigators aim to reduce placebo response. By contrast, clinicians often utilise placebo effects. Strategies to reduce nocebo responses in clinical trials and practice should be developed.

Multicenter Study Comparative Study
The comparative responsiveness of the patient self-report questionnaires and composite disease indices for assessing rheumatoid arthritis activity in routine care.
This paper aims to evaluate the internal and external responsiveness of the patient self-report questionnaires, comparatively to the traditional composite indices to assess the activity of rheumatoid arthritis (RA) in everyday practice. ⋯ The self-report questionnaires showed comparable internal and external responsiveness to the composite activity scores and allow for the detection of rheumatoid disease activity. They appear suitable for clinical decision making, epidemiologic research and clinical trials. Further longitudinal studies are needed to validate these encouraging results.

Randomized Controlled Trial
Six-and 12-month follow-up of an interdisciplinary fibromyalgia treatment programme: results of a randomised trial.
To assess the efficacy of a 6-week interdisciplinary treatment that combines coordinated psychological, medical, educational, and physiotherapeutic components (PSYMEPHY) over time compared to standard pharmacologic care. ⋯ An interdisciplinary treatment for FM was associated with improvements in quality of life, pain, physical function, anxiety and depression, and pain coping strategies up to 12 months after the intervention.
