Abstract Objective Systematic reviews are important in health care but are expensive to produce and maintain. The authors explore the use of automated transformations of Boolean queries to improve the identification of relevant studies for updates to systematic reviews. Materials and Methods A set of query transformations, including operator substitution, query expansion, and query reduction, were used to iteratively modify the Boolean query used for the original systematic review. The most effective transformation at each stage is identified using information about the studies included and excluded from the original review. A dataset consisting of 22 systematic reviews was used for evaluation. Updated queries were evaluated using the included and excluded studies from the updated version of the review. Recall and precision were used as evaluation measures. Results The updated queries were more effective than the ones used for the original review, in terms of both precision and recall. The overall number of documents retrieved was reduced by more than half, while the number of relevant documents found increased by 10.3%. Conclusions Identification of relevant studies for updates to systematic reviews can be carried out more effectively by using information about the included and excluded studies from the original review to produce improved Boolean queries. These updated queries reduce the overall number of documents retrieved while also increasing the number of relevant documents identified, thereby representing a considerable reduction in effort required by systematic reviewers.

Abstract. This editorial gives a brief introduction to the six articles included in the fourth “Hotspots in Psychology” of the Zeitschrift für Psychologie. The format is devoted to systematic reviews and meta-analyses in research-active fields that have generated a considerable number of primary studies. The common denominator is the research synthesis nature of the included articles, and not a specific psychological topic or theme that all articles have to address. Moreover, methodological advances in research synthesis methods relevant for any subfield of psychology are being addressed. Comprehensive supplemental material to the articles can be found in PsychArchives ( https://www.psycharchives.org ).

O uso do laser não ablativo no tratamento do melasma tem sido abordado em diversos estudos, porém, não há consenso na literatura quanto aos parâmetros e feitos de intervenções baseadas neste recurso. O objetivo deste estudo foi identificar e descrever parâmetros e efeitos do laser não ablativo no tratamento de hiperpigmentação de pele (melasma). Trata-se de uma revisão sistemática da literatura baseada no Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A busca eletrônica compreendeu as seguintes bases de dados: PubMed, Physiotherapy Evidence Database (PEDro), Science Direct e SciELO. Foram identificados inicialmente 641 documentos nas bases de dados eletrônicas, enquanto na busca manual 26 artigos foram encontrados, após leitura e análise 7 artigos foram selecionados. Foram analisados 7 artigos correspondentes as bases de dados PubMed e Science Direct, todos na língua inglesa e publicados a partir do ano de 2010. Apenas um estudo utilizou uma amostra maior que 30 indivíduos, os demais utilizaram em média 16 participantes, com predomínio do sexo feminino e classificação segundo Fitzpatrick entre III-V. O comprimento de onda variou entre 1064 nm a 1550 nm e a energia máxima não ultrapassou 4 J/cm². De acordo com as variáveis avaliadas, os protocolos testados demonstraram que o laser não ablativo foi ineficaz no tratamento de melasma facial, sobretudo após a interrupção da terapia.Palavras-chave: hiperpigmentação, laser não ablativo, fisioterapia dermato-funcional, revisão sistemática.
