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.

Troubles Du Comportement Alimentaire

Contexte : Les troubles périnéosphinctériens (TPS) survenant chez les patients souffrant de trouble du comportement alimentaire (TCA) sont des complications sous-abord ées dans la littérature. Le but de cette revue de la littérature était de faire le point sur l’état des connaissances actuelles pour aider le clinicien prenant en charge les TPS à les mettre en lien avec les TCA, et le clinicien prenant en charge les TCA à les prévenir et à les repérer le plus précocement possible, dans une perspective de réduction des risques et des dommages. Méthode : Deux revues de littérature ont été conduites, l’une portant sur les TPS d’origine digestive, l’autre sur les TPS d’origine urinaire. La sélection des articles s’est faite en nous référant aux recommandations PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) et à partir des bases de données PubMed et ScienceDirect. Résultats : Douze articles ont été retenus. Les TPS identifies sont la constipation, l’incontinence fécale, l’incontinence urinaire et le prolapsus rectal. Ils sont secondaires aux effets de la malnutrition sur la composante musculaire ainsi qu’à la pression abdominale exercée par des comportements visant à réguler la prise de poids, tels que les exercices physiques réalisés en hyperpression, les efforts de poussée lors de l’émission des selles et les vomissements provoqués. Conclusion : Une anamnèse précise et méticuleuse chez les personnes présentant un indice de masse corporel bas semble primordiale. L’usage de laxatifs est à proscrire avant un programme de renutrition d’au moins trois semaines.

Insight Into

A large number of research studies in structural health monitoring (SHM) have presented, extended, and used subspace system identification. However, there is a lack of research on systematic literature reviews and surveys of studies in this field. Therefore, the current study is undertaken to systematically review the literature published on the development and application of subspace system identification methods. In this regard, major databases in SHM, including Scopus, Google Scholar, and Web of Science, have been selected and preferred reporting items for systematic reviews and meta-analyses (PRISMA) has been applied to ensure complete and transparent reporting of systematic reviews. Along this line, the presented review addresses the available studies that employed subspace-based techniques in the vibration-based damage detection (VDD) of civil structures. The selected papers in this review were categorized into authors, publication year, name of journal, applied techniques, research objectives, research gap, proposed solutions and models, and findings. This study can assist practitioners and academicians for better condition assessment of structures and to gain insight into the literature.

ObjectiveTo critically appraise the quality of published systematic reviews (SRs) of randomised controlled trials (RCTs) in tendinopathy with regard to handling and reporting of results with special emphasis on strength of evidence assessment.Data sourcesMedline from inception to June 2020.Study eligibilityAll SRs of RCTs assessing the effectiveness of any intervention(s) on any location of tendinopathy.Data extraction and synthesisIncluded SRs were appraised with the use of a 12-item tool devised by the authors arising from the Preferred Reporting Items in Systematic Reviews and Meta-Analyses statement and other relevant guidance. Subgroup analyses were performed based on impact factor (IF) of publishing journals and date of publication.ResultsA total of 57 SRs were included published in 38 journals between 2006 and 2020. The most commonly used risk-of-bias (RoB) assessment tool and strength of evidence assessment tool were the Cochrane Collaboration RoB tool and the Cochrane Collaboration Back Review Group tool, respectively. The mean score on the appraisal tool was 46.5% (range 0%–100%). SRs published in higher IF journals (>4.7) were associated with a higher mean score than those in lower IF journals (mean difference 26.4%±8.8%, p=0.004). The mean score of the 10 most recently published SRs was similar to that of the first 10 published SRs (mean difference 8.3%±13.7%, p=0.54). Only 23 SRs (40%) used the results of their RoB assessment in data synthesis and more than half (n=30; 50%) did not assess the strength of evidence of their results. Only 12 SRs (21%) assessed their strength of evidence appropriately.ConclusionsIn light of the poor presentation of evidence identified by our review, we provide recommendations to increase transparency and reproducibility in future SRs.
