Effectiveness of cloth face masks to prevent viral spread: a meta-analysis.

BACKGROUND: The effectiveness of cloth face masks to prevent viral spread has not yet been conclusively established. In this meta-analysis, we evaluate their effectiveness in comparison to standard medical/surgical and N95-typed masks against viral spread. METHODS: We identified literature through a systematic search in three databases and meta-analytically synthesized relevant studies by means of random-effects as well as multilevel modelling. RESULTS: Twelve studies comprising k = 28 effect sizes (N = 338) were included. Medical/surgical and N95-typed masks outperformed cloth masks, yielding a large effect (g = 1.40). This effect remained robust when data were grouped according to comparisons with medical/surgical masks (g = 1.25) and N95-typed masks (g = 1.29). However, effects were differentiated according to mask fit, indicating reversals of signs when cloth mask effects were compared with ill-fitting medical/surgical and N95-typed masks (gs = -12.50 and - 10.90, respectively). CONCLUSIONS: Cloth face masks were found to have significantly poorer filtering performance than medical/surgical masks and N95 masks, but only if non-cloth masks were properly fitted. Our results illustrate the necessity of using well-fitting medical/surgical or N95-typed masks to prevent viral spread, although some allowance should be made in circumstances where higher compliance with cloth mask mandates are expected.

Good mental health in people with intellectual disabilities: a systematic review.

While mental disorders have been broadly researched in people with intellectual disabilities (ID), comparatively less attention has been given to the conceptualisation of good mental health for this population. To capture existing concepts, definitions and measurement approaches of good mental health a systematic literature review was conducted following PRISMA guidelines. The search was carried out in eleven databases, using various synonyms of (i) intellectual disability, (ii) mental health, (iii) wellbeing, (iv) definition, and (v) assessment. A total of 2,046 datasets were identified, of which 37 met the inclusion criteria and were analysed using reflexive thematic analysis and content analysis. Results show four main themes: (1) environment, (2) absence of mental illness, (3) physical health, and (4) psychosocial functioning. The fourth was the most dominant theme and was further divided into five sub-themes: (1) emotionality, (2) interpersonal relations, (3) realise own potential, (4) personal resources, and (5) overall appraisal of life. Our findings reveal different conceptualisations of wellbeing, which is a vital part of good mental health, but highlight a notable research gap in the actual definition and conceptualisation of good mental health for people with ID.

Routine laboratory parameters to support decision on parenteral nutrition in palliative care.

Introduction: Parenteral nutrition (PN) is widely used in palliative care (PC), but there is limited evidence to support its use at the end of life (EOL). This aim of this was to investigate the relationship between routine laboratory parameters and survival in patients receiving PN, and to develop a decision tree model to support clinicians decide whether to start or forgo PN. Methods: The laboratory parameters of 113 patients with advanced diseases who were admitted to a specialized palliative care unit (PCU) were analyzed at two points in time: T0 = before PN, T1 = two weeks after initiation of PN. Univariate Mann-Whitney U-tests and multivariate linear regression models, as well as a decision tree analysis were computed; all in relation to survival time. Results: The final regression model was significant with p = 0.001 (adjusted R2 = 0.15) and included two predictors for survival time after PN initiation: the CRP/albumin ratio and urea at T1 (ps = 0.019). Decision tree analysis revealed three important predictors for classification of survival time after PN initiation: CRP, urea, and LDH (all at T0). Discussion: The decision tree model may help to identify patients likely to benefit from PN, thus supporting the clinical decision whether or not to start PN.

Concepts of good mental health and wellbeing in people with intellectual disability: Study protocol for a systematic review.

Introduction: Good mental health is an indispensable aspect of good general health and different definitions of good mental health have been developed for the general population. However, it is not clear how these definitions can be applied to people with intellectual disabilities (ID), as they may have difficulties in many facets encompassed in existing definitions. Yet, people with ID can be mentally healthy or mentally ill just as people without ID. Objective: The aim of this systematic review is to summarize existing concepts, definitions, and measurement approaches of good mental health and wellbeing for people with ID. Methods: A comprehensive, systematic literature review will be conducted in 11 databases, including ASSIA, CINAHL, Cochrane Library, ERIC, MedRxiv, OSF preprints, ProQuest Dissertations & Theses Global, PsycINFO, PubMed, Scopus, and Web of Science. By including preprints and theses servers in the search strategy, we will also consider grey and unpublished literature. The quality of included studies will be rated using standardized checklists. All steps of the literature search, data extraction, and quality rating will be performed independently by two trained researchers. Disagreements will be resolved through discussion between these researchers and, if required, by consulting a third team member. In a narrative synthesis, existing approaches to good mental health and wellbeing for people with ID will be systematically described and linked to current research in mental health for people with and without ID. Discussion: The findings of this study will provide researchers and practitioners with an evidence-based overview of current approaches to good mental health and wellbeing of people with ID. We will explore and discuss the individual facets of the definitions, concepts, and measurement approaches and identify possible gaps which need to be addressed. This will strengthen future research on this topic and focus research activities on important and unresolved themes that need to be targeted to promote health equity for people with ID.
