- Description: In recent years, the drive for the Healthcare Monitoring Application (HMA) aims to provide continuous remote monitoring of a patient's health. For this to happen, the sensors in the monitoring component of the Body Area Wireless Sensor Networks (BAWSN) need to continuously send data to a Healthcare Application. We show that to provide continuous health data, the BAWSN depends on the collective data delivered by all the sensor nodes and not on a single sensor because medical diagnosis is rarely performed from a single data point. In addition, the arrival time of data should occur within the expected time to be indicative of the actual health of the patient. In this paper, we characterize the HMA as a time-critical application because the BAWSN has stringent timing requirements concerning the arrival of data from the sensor nodes within the defined critical time. Thereby, we formulate the critical time parameters to evaluate the BAWSN operations.

- Description: Background: Same-sex attracted young adults have been found to experience higher rates of mental health problems and greater difficulties in accessing specialist mental health care services compared to their heterosexual peers. Internet-based mental health interventions have the potential to be more engaging and accessible to young adults compared to those delivered face-to-face. However, they are rarely inclusive of lesbian women and gay men. Thus, the current study aims to evaluate the effectiveness of an online mental health and wellbeing program, Out & Online (http://www.outandonline.org.au), in comparison to a wait-list control group, for reducing anxiety and depressive symptoms in same-sex attracted young adults aged between 18 and 25 years. Methods/Design: We are recruiting, through media and community organisations, 200 same-sex attracted young adults with anxiety and/or depressive symptoms and mild to moderate psychological distress (Kessler-10 score between 16 to 21). Participants will be randomly allocated to the intervention (the online program) or the wait-list control group based on a permuted blocked randomisation method to allow for stratification by gender. Participants in the intervention group will receive a tailored program for up to three types of mental health difficulties simultaneously. The primary outcome of anxiety and/or depressive symptoms, and secondary outcomes related to psychological distress, wellbeing and health behaviour will be measured at pre-intervention (0 week), post-intervention (8 weeks) and at a 3-month follow-up (20 weeks). Discussion: This online mental health and wellbeing program will be one of the first online interventions to be designed specifically to be relevant for same-sex attracted individuals. If the program is found to be effective it will improve access to specialist same-sex attracted-relevant mental health services for young adults and will facilitate wellbeing outcomes for these individuals. This program will also be a significant development in the delivery of tailored interventions that target multiple types of mental health conditions simultaneously. © 2014 Abbott et al.

- Description: Blockchain technologies recently emerging for eHealth, can facilitate a secure, decentral- ized and patient-driven, record management system. However, Blockchain technologies cannot accommodate the storage of data generated from IoT devices in remote patient management (RPM) settings as this application requires a fast consensus mechanism, care- ful management of keys and enhanced protocols for privacy. In this paper, we propose a Blockchain leveraged decentralized eHealth architecture which comprises three layers: (1) The Sensing layer –Body Area Sensor Networks include medical sensors typically on or in a patient body transmitting data to a smartphone. (2) The NEAR processing layer –Edge Networks consist of devices at one hop from data sensing IoT devices. (3) The FAR pro- cessing layer –Core Networks comprise Cloud or other high computing servers). A Patient Agent (PA) software replicated on the three layers processes medical data to ensure reli- able, secure and private communication. The PA executes a lightweight Blockchain consen- sus mechanism and utilizes a Blockchain leveraged task-offloading algorithm to ensure pa- tient’s privacy while outsourcing tasks. Performance analysis of the decentralized eHealth architecture has been conducted to demonstrate the feasibility of the system in the pro- cessing and storage of RPM data.

- Description: Medical imaging has become of vital importance for diagnosing diseases and conducting noninvasive procedures. Advances in eHealth applications are challenged by the fact that Digital Imaging and Communications in Medicine (DICOM) requires high-resolution images, thereby increasing their size and the associated computational complexity, particularly when these images are communicated over IP and wireless networks. Therefore, medical research requires an efficient coding technique to achieve high-quality and low-complexity images with error-resilient features. In this study, we propose an improved coding scheme that exploits the content features of encoded videos with low complexity combined with flexible macroblock ordering for error resilience. We identify the homogeneous region in which the search for optimal macroblock modes is early terminated. For non-homogeneous regions, the integration of smaller blocks is employed only if the vector difference is less than the threshold. Results confirm that the proposed technique achieves a considerable performance improvement compared with existing schemes in terms of reducing the computational complexity without compromising the bit-rate and peak signal-to-noise ratio. © 2013 IEEE.

- Description: Objective: To develop and evaluate the usability of iConquerFear, an online self-management adaptation of an efficacious face-to-face therapist-delivered treatment for fear of cancer recurrence (FCR). Methods: iConquerFear development was theory based and person based. Development was guided by Ritterband et al's behaviour change model for internet interventions. iConquerFear end users (cancer survivors) provided iterative feedback in accordance with Yardley et al's person-based approach to maximise engagement and usability. Online focus groups and cognitive interviews were conducted to evaluate the usability of iConquerFear. Discussions were recorded, transcribed verbatim, and thematically analysed. Results: Five online FCR modules were developed. Twenty-three cancer survivors (47% of those eligible) participated; 11/23 (58%) were breast cancer survivors, and average age was 53 years (SD = 10.8). Thematic saturation was reached after six focus groups (n = 16) and seven individual think-aloud interviews. Thematic analysis produced five overarching themes: easy navigation essential; satisfaction and engagement with content; flexible access is key; normalising and empowering; and a useful first step. Conclusions: Online self-management interventions like iConquerFear have the potential to address the unmet supportive care needs reported by burgeoning numbers of cancer survivors. However, that potential may not be realised unless interventions are rigorously developed and user tested, as benefits are constrained by limited engagement. Themes from the usability testing of iConquerFear highlight the importance of developing flexible, tailored, interactive, and contextual online self-management interventions for people with cancer. © 2019 John Wiley & Sons, Ltd.

- Description: Objective(s): The aim of this paper was to report on qualitative survey responses provided by older Australian adults regarding their preferences for Internet-based services and content. Methods: Two qualitative questions (‘What type of Internet-based mental health and well-being (1) services, and (2) content would be of most interest to you?’) from a broader survey investigating the mental and physical health of older Australians were thematically analysed for commonly occurring themes. Eighty-nine participants aged 65 years or older (mean age = 71 years, SD = 5.30) responded to at least one qualitative question. Participants were primarily female (60%, n = 53), born in Australia (65%, n = 58), in a relationship (58%, n = 52), living in the community (79%, n = 70) and relatively well educated, with the majority having completed a university degree (38%, n = 34). Results: Themes indicated that participants were most interested in Facebook-style services (n = 17), chat groups (n = 16) and email-based services (n = 4) designed specifically for older adults (n = 14). However, some concerns were raised regarding the trustworthiness of Internet-based services, with the largest proportion of participants (n = 22) noting that they were unlikely to use Internet- or social media-based services. The primary content-related themes were mental fitness (n = 34), grief and loss (n = 20), health information (n = 13), socialisation (n = 11) and physical fitness (n = 10). Conclusions: Participants indicated interest in tailor-made Facebook-style services for older adults that allow them to communicate with their peers and create new social networks and incorporate content relating to strategies for working on mental and physical fitness, information on coping with grief and loss, as well as health information. These findings can be used by organisations to develop Internet-based services and content for older Australian adults. © 2023 The Authors.
