"No language restrictions" in database searches: what does this really mean?
The aim of this study was to investigate the coverage of non-English journals by MEDLINE((R)) and EMBASE, the two major biomedical databases used for identifying studies for possible inclusion in systematic reviews and meta-analyses. A series of searches were conducted to compare the coverage of journals in languages other than English. ⋯ This study has highlighted the existence of a database coverage bias, in terms of the systematic exclusion of journals from certain countries and/or in certain languages. Searching that relies only on English language databases may result in failure to find many relevant studies published in languages other than English, irrespective of the research question and the avoidance of any language restrictions.

Randomized Controlled Trial Clinical TrialPerception of bodily sensation as a predictor of treatment response to acupuncture for postoperative nausea and vomiting prophylaxis.
Conditions associated with the response to acupuncture treatment remain widely elusive. This study aimed to identify predictors of treatment response in patients undergoing acupuncture treatment for prevention of postoperative nausea and vomiting (PONV). An intervention-specific questionnaire was developed to assess perception of bodily sensations (PBS) in patients undergoing acupuncture treatment. ⋯ The incidence of PONV after breast surgery seems to be influenced by some psychological mechanisms. In this group of patients, acupuncture might be more effective in patients who have low PBS.
