Anxiety is common in long-term care (LTC), but it is unclear which anxiety detection tools are accurate when compared to a reference standard for residents of LTC. Four databases and grey literature sources were searched using the search concepts “anxiety” and “LTC”. Included studies evaluated the diagnostic accuracy of an anxiety detection tool compared to a reference standard in LTC residents. Diagnostic accuracy measures were extracted. Four articles out of 4,620 met the inclusion criteria. Despite limited evidence and poorly reported study procedures and characteristics, the Geriatric Anxiety Inventory (sensitivity: 90.0%, specificity: 86.2%) and the Hospital Anxiety and Depression Scale-Anxiety (sensitivity: 90.0%, specificity: 80.6%) had the best performance when detecting generalized anxiety disorder. We identified four anxiety detection tools appropriate for use in LTC; a critical first step to diagnosing and managing anxiety in residents of LTC. Non-generalized anxiety disorders and tool feasibility must be further evaluated.

Although geriatric depression is a prevalent, serious, and under-recognized mental health condition in residential care facilities, there is a dearth of related research in Canada. This exploratory mixed methods study examines the perspectives and practices of regulated nurse professionals on assessment of geriatric depression in residential care facilities in Alberta. Findings from the quantitative surveys (n = 635) and qualitative interviews (n = 14) suggest that geriatric depression is not systematically assessed in these care settings due to multiple challenges, including confusing assessment protocol, inconsistent use and contested clinical utility of current assessment methods in facilities, limited availability of mental health professionals in facilities, and the varied views of regulated nurse professionals on who is responsible for depression assessment in facilities. Implications and future research directions are discussed.

Ternium Siderar has recently installed a commercial sensor that measures the soundoriginated during blowing. A proper analysis of this signal may give valuable informationabout the slopping tendency of the heat. Data from more than 4000 heats were collected andthoroughly analyzed. The influences of the materials charged and of their compositions onthe slag slopping tendency were investigated. Based on these results, an application toevaluate the risk of slopping for given process conditions was developed.

Une recherche de toxicité a été réalisée sur dix-huit souches isolées à partir d'efflorescences de cyanobactéries récoltées dans l'Ouest de la France et deux souches provenant de cultures de collection. Un biotest basé sur la sensibilité de larves d'une crevette marine Artemia salina a été développé et comparé à des bioessais sur souris, outil de référence pour la détection des toxines de cyanobactéries. Parmi les souches provenant du milieu naturel, six se sont avérées hépatotoxiques par les bioessais sur souris. Pour l'hépatotoxicité, les réponses du test A. salina recouvrent celles données par le test souris.
