- Background:Dementia is a general term for several progressive neurodegenerative disorders including Alzheimer’s disease. Timely and accurate detection is crucial for early intervention. Advancements in artificial intelligence present significant potential for using machine learning to aid in early detection.Objective:Summarize the state-of-the-art machine learning-based approaches for dementia prediction, focusing on non-invasive methods, as the burden on the patients is lower. Specifically, the analysis of gait and speech performance can offer insights into cognitive health through clinically cost-effective screening methods.Methods:A systematic literature review was conducted following the PRISMA protocol (Preferred Reporting Items for Systematic Reviews and Meta-Analyses). The search was performed on three electronic databases (Scopus, Web of Science, and PubMed) to identify the relevant studies published between 2017 to 2022. A total of 40 papers were selected for review.Results:The most common machine learning methods employed were support vector machine followed by deep learning. Studies suggested the use of multimodal approaches as they can provide comprehensive and better prediction performance. Deep learning application in gait studies is still in the early stages as few studies have applied it. Moreover, including features of whole body movement contribute to better classification accuracy. Regarding speech studies, the combination of different parameters (acoustic, linguistic, cognitive testing) produced better results.Conclusions:The review highlights the potential of machine learning, particularly non-invasive approaches, in the early prediction of dementia. The comparable prediction accuracies of manual and automatic speech analysis indicate an imminent fully automated approach for dementia detection.

- BACKGROUND: Individuals with stroke rehabilitated in an enriched environment (EE) compared to a non-EE are more likely to participate in cognitive and social activities, promoting their rehabilitation and well-being. There is a need for a more comprehensive understanding of methods to implement EEs within complex health systems, particularly in stroke units.OBJECTIVE: The aim of this systematic review was to compile the concept of an EE in stroke units.METHODS: The literature was sourced from CINAHL, Embase, and Medline databases. A detailed screening and sifting process was used to identify relevant literature. Multiple reviewers independently appraised the identified literature using a Mixed-methods Appraisal Tool. After screening 336 studies, 11 were included.RESULTS: This review reveals an EE is challenging to define and almost exclusively about activities based on access to individual and communal equipment. Generally, there are no common descriptions or conceptual agreements.CONCLUSIONS: To the best of our knowledge, this is the first study to systematically review the concept of an EE in stroke units and shows that more studies on EEs are needed. The weak definitions and unclear theoretical backgrounds of an EE in the included studies could challenge operationalization. Future research should be based on more precise definitions of an EE and broader interventions that include changes to built and natural environments.

The use of the PARIHS framework in implementation research and practice-a citation analysis of the literature
- 2020
-
Ingår i: Implementation science : IS. - : Springer Science and Business Media LLC. - 1748-5908. ; 15:1
-
Forskningsöversikt (refereegranskat)abstract
- BACKGROUND: The Promoting Action on Research Implementation in Health Services (PARIHS) framework was developed two decades ago and conceptualizes successful implementation (SI) as a function (f) of the evidence (E) nature and type, context (C) quality, and the facilitation (F), [SI = f (E,C,F)]. Despite a growing number of citations of theoretical frameworks including PARIHS, details of how theoretical frameworks are used remains largely unknown. This review aimed to enhance the understanding of the breadth and depth of the use of the PARIHS framework. METHODS: This citation analysis commenced from four core articles representing the key stages of the framework's development. The citation search was performed in Web of Science and Scopus. After exclusion, we undertook an initial assessment aimed to identify articles using PARIHS and not only referencing any of the core articles. To assess this, all articles were read in full. Further data extraction included capturing information about where (country/countries and setting/s) PARIHS had been used, as well as categorizing how the framework was applied. Also, strengths and weaknesses, as well as efforts to validate the framework, were explored in detail. RESULTS: The citation search yielded 1613 articles. After applying exclusion criteria, 1475 articles were read in full, and the initial assessment yielded a total of 367 articles reported to have used the PARIHS framework. These articles were included for data extraction. The framework had been used in a variety of settings and in both high-, middle-, and low-income countries. With regard to types of use, 32% used PARIHS in planning and delivering an intervention, 50% in data analysis, 55% in the evaluation of study findings, and/or 37% in any other way. Further analysis showed that its actual application was frequently partial and generally not well elaborated. CONCLUSIONS: In line with previous citation analysis of the use of theoretical frameworks in implementation science, we also found a rather superficial description of the use of PARIHS. Thus, we propose the development and adoption of reporting guidelines on how framework(s) are used in implementation studies, with the expectation that this will enhance the maturity of implementation science.

The Journal Korall and Hungarian Social History : Between International and National Contexts

Forskningsöversikt (refereegranskat)abstract
- This review essay evaluates the evolution of the Hungarian journal of social history, Korall társadalomtörténeti folyóirat (Coral: A journal of social history), founded in 1999 as a new forum of social history research. Korall promoted two distinct understandings of social history, stated only implicitly in the first years of the journal, but later elaborated more explicitely by the editors, as core definitions of their research programme. A first, narrow acceptation places social history within the field of (historical) sociology and favours structural approaches and concepts specific to the social sciences rather than the actual historical context. A second definition is wider, including a variety of topics such as environmental history, cultural history, economic, and demographic history, being meant to function as a powerful counter-discourse against positivistic, traditional and political-orientated history, still dominant in contemporary Hungarian historiography. Based on a combination of qualitative and quantitative content analysis, the review essay argues that, during its eight years of existance to date, Korall has undergone a process of internationalization. Although most articles published in the journal continue to focus on topics pertaining to the history of Hungary—especially during the "dualist period," 1867-1918—references to international events, authors, and theories have lately acquired a greater importance

Forskningsöversikt (refereegranskat)abstract
- Purpose: To offer guidance for future welfare technology research, this review provides an overview of current knowledge gaps and research needs as reported in primary scientific studies addressing the implementation of welfare technology for older people, people with disabilities and informal caregivers.Materials and methods: This paper conducted a state-of-the-art review based on systematic searches in 11 databases followed by a descriptive qualitative analysis of 21 selected articles.Results: Knowledge gaps and research needs were identified concerning two categories: research designs and populations and focus of research. The articles reported needs for comparative studies, longitudinal studies, and demonstration trials as well as the development of co-design processes involving technology users. They also called for studies applying a social system theory approach, involving healthy and frail older adults, representative samples of users within and across countries, informal and formal caregivers, inter-and multidisciplinary teams, and care organizations. Moreover, there are reported needs for studies of acquirement, adoption and acceptance of welfare technology, attitudes, beliefs, and context related to welfare technology, caregiver perspectives on welfare technology, services to provide welfare technology and welfare technology itself.Conclusions: There are considerable knowledge gaps and research needs concerning the implementation of welfare technology. They relate not only to the research focus but also to research designs, a social system theory approach and study populations.

Is 'legal empowerment of the poor' relevant to people with disabilities in developing countries? An empirical and normative review.
- 2013

Forskningsöversikt (refereegranskat)abstract
- Background : Legal empowerment of the poor is highly relevant to public health as it aims to relieve income poverty, a main determinant of health. The Commission on Legal Empowerment of the Poor (CLEP) has proposed legal empowerment measures in the following four domains: access to justice and the rule of law, property, labor, and business rights. Despite being overrepresented among the poor, CLEP has not explicitly considered the situation of people with disabilities. Objectives : To examine the empirical evidence for the relevance of the CLEP legal empowerment measures to people with disabilities in low- and lower middle-income countries, and to evaluate the extent to which the Convention on the Rights of Persons with Disabilities (CRPD) addresses those measures. Methods : Critical literature review of empirical studies and a checklist assessment of the CRPD. Results : Fourteen included articles confirm that people with disabilities experience problems in the domains of access to justice and the rule of law, labor rights, and business rights. No texts on property rights were found. Evidence for the effectiveness of the proposed measures is insufficient. Overall, the CRPD fully or partially supports two-thirds of the proposed measures (seven out of nine measures for access to justice and the rule of law, none of the five measures for property rights, all seven measures for labor rights, and six out of nine measures for business rights). Conclusions : Although most of the domains of the CLEP legal empowerment measures are relevant to people with disabilities from both empirical and normative perspectives, it is uncertain whether the devised measures are of immediate relevance to them. Further research is warranted in this regard.

- Background. Many publications report the prevalence of chronic kidney disease (CKD) in the general population. Comparisons across studies are hampered as CKD prevalence estimations are influenced by study population characteristics and laboratory methods. Methods. For this systematic review, two researchers independently searched PubMed, MEDLINE and EMBASE to identify all original research articles that were published between 1 January 2003 and 1 November 2014 reporting the prevalence of CKD in the European adult general population. Data on study methodology and reporting of CKD prevalence results were independently extracted by two researchers. Results. We identified 82 eligible publications and included 48 publications of individual studies for the data extraction. There was considerable variation in population sample selection. The majority of studies did not report the sampling frame used, and the response ranged from 10 to 87%. With regard to the assessment of kidney function, 67% used a Jaffe assay, whereas 13% used the enzymatic assay for creatinine determination. Isotope dilution mass spectrometry calibration was used in 29%. The CKD-EPI (52%) and MDRD (75%) equations were most often used to estimate glomerular filtration rate (GFR). CKD was defined as estimated GFR (eGFR) <60 mL/min/1.73 m(2) in 92% of studies. Urinary markers of CKD were assessed in 60% of the studies. CKD prevalence was reported by sex and age strata in 54 and 50% of the studies, respectively. In publications with a primary objective of reporting CKD prevalence, 39% reported a 95% confidence interval. Conclusions. The findings from this systematic review showed considerable variation in methods for sampling the general population and assessment of kidney function across studies reporting CKD prevalence. These results are utilized to provide recommendations to help optimize both the design and the reporting of future CKD prevalence studies, which will enhance comparability of study results.

Effectiveness of interventions to address the negative health outcomes of informal caregiving to older adults : protocol for an umbrella review
- 2021

Forskningsöversikt (refereegranskat)abstract
- Introduction Informal (unpaid) caregivers play an essential role in caring for older people, whose care needs are often not fully met by formal services. While providing informal care may be a positive experience, it can also exert a considerable strain on caregivers’ physical and mental health. How to best support the needs of informal caregivers remains largely debated. This umbrella review (review of systematic reviews) aims to evaluate (1) whether effective interventions can mitigate the negative health outcomes of informal caregiving, (2) whether certain types of interventions are more effective than others, (3) whether effectiveness of interventions depends on caregiver/receiver, context or implementation characteristics and (4) how these interventions are perceived in terms of acceptability, feasibility and added value.Methods and analysis We will include systematic reviews of primary studies focusing on the effectiveness of interventions (public or private, unifaceted or multifaceted, delivered by health or social care professionals or volunteers) aimed at reducing the impact of caregiving on caregivers’ physical or mental health. This will also include quantitative and qualitative syntheses of implementation studies. The literature search will include the following databases: Medline, CINAHL, PsycINFO and Web of Science. A key informant-guided search of grey literature will be performed. Quality appraisal will be conducted with the AMSTAR-2 checklist for quantitative reviews and with an ad hoc checklist for qualitative syntheses. Narrative and tabular summaries of extracted data will be produced, and framework synthesis will be employed for weaving together evidence from quantitative studies in effectiveness reviews with findings on implementation from qualitative studies.Ethics and dissemination This umbrella review will use data from secondary sources and will not involve interactions with study participants; it is thus exempt from ethical approval. Results will be presented at international conferences and will be published in a peer-reviewed journal.
