    BACKGROUND: Digital devices such as smartphones, tablets, computers, and laptops are used for various purposes. The digital display quality has been improved, making it less tiring and more favoured among users. This study aimed to review the visual comfort of digital devices and the preferences of digital display settings that enhance the visual comfort experienced by digital device users.

    METHODS: A search of PubMed, EBSCO host MEDLINE Complete, Scopus database, Google Scholar, and manual citation review was conducted, covering the period between 2010 and 2022. The criteria were selected based on the PRISMA statements. The search mainly focused on finding the existing literature on digital devices that contribute to visual discomfort and digital device settings that provide better visual comfort.

    RESULTS: The database search resulted in 533 references via the application of Microsoft Excel. There were 28 studies included in the final assessment. Twelve studies accounted for digital devices that contributed to visual discomfort, while another sixteen studies for digital device settings provided better visual comfort.

    CONCLUSION: Digital displays with high luminance contrast, positive polarity and adequate colour were preferred for better visual comfort. Meanwhile, smaller fonts were preferred for desktops and laptops, while larger fonts were favoured for smartphones. This study provides insights for digital display developers to learn and improve their display technology to fit the preferences expressed.

    Iran J Public Health, 2022 Aug;51(8):1706-1717.
    PMID: 36249108 DOI: 10.18502/ijph.v51i8.10251
    BACKGROUND: Occupational noise exposure is one of the environmental factors that pose safety and health risks among workers in factories. This systematic review focuses on the activities that cause noise hazards toward workers' heart rate, other physiological conditions, and strategies to prevent noise exposure in the manufacturing industry.

    METHODS: Through a comprehensive literature review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and the Cochrane method were used. The appraisal of quality was conducted by using the Critical Appraisal Skills Programme (CASP) to fulfil the selected keywords.

    RESULTS: Occupational noise exposure not only affects the workers' most common issues, such as heart rate, but also other physiological factors, such as blood pressure. The outcome showed that different level of continuous noise exposure with high intensity decibels affects the heart rate of the workers. Source, path, receiver was recommended strategies for basic noise prevention in engineering control.

    CONCLUSION: Therefore, noise give significant effects towards human workers in related industry. Study related to noise effects towards heart rate performance led to future prevention and innovation.

    BACKGROUND: Post-exposure prophylaxis (PEP) is an effective method for preventing rabies, a highly fatal infection in exposed persons. Malaysia is currently using the purified Vero cell rabies vaccine (PVRV). Nonetheless, there are other commercially available vaccine types and regimens. This systematic review aimed at comparing the effectiveness of the different PEP vaccines, regimens and routes of administration among Asian populations.

    METHODS: We systematically reviewed the PubMed and Web of Science databases for articles reporting on the effectiveness of PEP vaccination against rabies among Asian populations between 2015 and 2019.

    RESULTS: Our search identified 11 relevant studies. Majority of study either used PCECV or PVRV type of vaccine, with different regimes and method. All are non-inferior to the other. Most of the studies recorded adequate response by Day 14 of vaccination. Nonetheless, the intradermal (ID) vaccination used minimal volume of vaccine used in all settings, thus cost less and the concurrent administration of RIG to the wound(s) doesn't affect the RVNA GMT response.

    CONCLUSION: PCECV, using either the Essen or Zagreb regimen, might be a useful alternative for the healthy population in the context of PVRV shortage, especially during an outbreak. Use of the Zagreb or Thai Red Cross (TRC) regimens can be considered (either PVRV or PCECV), as both demonstrate good immunogenic outcomes in Asian populations.
