BACKGROUND Disease screening identifies a disease in an individual/community at an early stage to prevent or treat the condition effectively. The current COVID-19 pandemic has restricted hospital visits for screening and other healthcare services resulting in the disruption of screening for diseases such as cancer, diabetes and CVD. Smartphone technologies, coupled with built-in sensors and wireless technologies, enable the smartphone to function as a device for disease screening and monitoring with negligible additional costs. OBJECTIVE This review aimed to evaluate the use of smartphone applications (apps) in the disease screening and acceptability of this technology in the medical and healthcare sectors. METHODS We followed a systematic review process to assess the scope for the app in the disease screening process. Four databases (Medline complete, Web of Science, Embase, and Proquest) were searched. Articles published in English and examining the use of the app in disease screening were included. Primary outcomes for the research articles and their statistically significant Results showed that app-based screening group had significant (OR:1.7, 95% CI: 1.2–2.4) eye care utilisation compared to their traditional screening counterparts. A good correlation between clinical Snellen and smartphone visual acuity measurements (ρ=.91) is observed. For depression screening, the ROC curve is .8012, indicating that mental-health ratings are comparable to Patient Health Questionnaire-9 (PHQ-9) results, and could be used as a depression screening tool in practice. Although the findings of cognitive impairment suggest that the digital-version readings are similar to the standard paper-version readings, the participants preferred devices with larger screen (e.g. tablet). Also, the smartphone-compatible oximeter is a weak predictor to detect central sleep apnoea in stable heart failure participants. value, where applicable are presented and discussed.

CONCLUSIONS The review observed a significant statistical relationship between the app and standard clinical screening. Critical considerations when designing, developing, and deploying smartphone solutions is laid forth to provide equitable healthcare solutions without barriers. Furthermore, the findings might increase the research prospects to evaluate smartphone solutions as valid and reliable screening solutions.

Cognitive dysfunction affects the performance of Activities of Daily Living (ADL) and the quality of life of people with these deficits and their caregivers. To the knowledge of the authors, to date, there are few studies that focus on knowing the relationship between personal autonomy and deductive reasoning and/or categorization skills, which are necessary for the performance of the ADL. The aim of this study was to explore the relationships between ADL and categorization skills in older people. The study included 51 participants: 31 patients with cognitive impairment and 20 without cognitive impairment. Two tests were administered to assess cognitive functions: (1) the Montreal Cognitive Assessment (MoCA); and (2) the digital version of Riska Object Classification test (ROC-d). In addition, the Routine Tasks Inventory-2 (RTI-2) was applied to determine the level of independence in activities of daily living. People with cognitive impairment performed poorly in categorization tasks with unstructured information (p = 0.006). Also, the results found a high correlation between cognitive functioning and the performance of ADLs (Physical ADL: r = 0.798; p < 0.001; Instrumental ADL: r = 0.740; p < 0.001), a moderate correlation between Physical ADLs and categorization skills (unstructured ROC-d: r = 0.547; p < 0.001; structured ROC-d: r = 0.586; p < 0.001) and Instrumental ADLs and categorization skills in older people (unstructured ROC-d: r = 0.510; p < 0.001; structured ROC-d: r = 0.463; p < 0.001). The ROC-d allows the assessment of categorization skills to be quick and easy, facilitating the assessment process by OT, as well as the accuracy of the data obtained.

How the social and institutional context is structured and represented by its actors has an impact on positive aging representations. This qualitative study explores professionals’ views on positive aging, how they promote positive aging in their practice and what disparities occur between their discourses and the actual practice of promoting positive aging. Interviews were conducted with professionals from different active aging promotion services and analyzed with thematic coding. Findings show professionals hold negative views on aging while trying to promote positive views in their work, illustrating an existing theory-practice gap. Strategies used in practice can be integrated in existing agency models and inform interventions and active aging policies.

Abstract Objective: The Dimensional Anhedonia Rating Scale (DARS) is a novel questionnaire to assess anhedonia of recent validation. In this work we aim to study the equivalence between the traditional paper-and-pencil and the digital format of DARS. Methods: 69 patients filled the DARS in a paper-based and digital versions. We assessed differences between formats (Wilcoxon test), validity of the scales (Kappa and Intraclass Correlation Coefficients), and reliability (Cronbach’s alpha and Guttman’s coefficient). We calculated the Comparative Fit Index and the Root Mean Squared Error associated with the proposed one-factor structure. Results: Total scores were higher for paper-based format. Significant differences between both formats were found for three items. The weighted Kappa coefficient was approximately 0.40 for most of the items. Internal consistency was greater than 0.94, and the Intraclass Correlation Coefficient for the digital version was 0.95 and 0.94 for the paper-and-pencil version (F= 16.7, p < 0.001). Comparative Adjustment Index was 0.97 for the digital DARS and 0.97 for the paper-and-pencil DARS, and Root Mean Squared Error was 0.11 for the digital DARS and 0.10 for the paper-and-pencil DARS. Conclusion: The digital DARS is consistent in many respects to the paper-and-pencil questionnaire, but equivalence with this format cannot be assumed without caution.

Communities are increasingly familiar with Internet technology became one of the reasons for the rapid growth of digital newspaper in Indonesia. The ability of the media presents news in brief, fast, accessible and inexpensive form the basis of high growth of consumer interest in digital newspaper / electronic. Technological developments, triggering changes to the newspaper that had shaped the physical print later developed in digital form. In principle, newspaper print and digital newspapers contain messages or the same news, namely providing information to readers about the actual and weighted, as well as other light information that is entertainment. Review the anatomy of the digital newspaper layout is a study to trace and explore what and how the anatomy of a newspaper page layout, at least to provide information and understanding of the anatomy of the layouts in outline. Process layout in the digital version is no different from print media, which distinguishes its output only. In the process to any design layout of a medium, a designer is still expected to possess and master the basic principles such as layout hierarchy, emphasis, balance, and unity.
