Health and mobility: Current status and future paradigms

The movement of telemedicine to the wireless and mobile Internetable applications is imminent in the next few years. This migration from the desktop platforms to the wireless and mobile configurations will have significant impact on the future health care delivery system and their globalisation. The recent telecommunications and biomedical computing advances will significantly enhance the current methodologies of telemedicine and telecare systems. This editorial will present some of the evolutionary issues and important aspects that have to be considered in the developing technologies for the next generation of Internet and Third Generation of Mobile Systems (3G), geared for future telemedical applications. These will provide new dimensions to existing medical services and areas of outreach, that are not possible in the current generation and will have tremendous impact on how the health care delivery will be shaped for the 21 Century

An improved closed-loop stability related measure for finite-precision digital controller realizations

The pole-sensitivity approach is employed to investigate the stability issue of the discrete-time control system, where a digital controller, implemented with finite word length (FWL), is used. A new stability related measure is derived, which is more accurate in estimating the closed-loop stability robustness of an FWL implemented controller than some existing measures for the pole-sensitivity analysis. This improved stability measure thus provides a better criterion to find the optimal realizations for a generic controller structure that includes output-feedback and observer-based controllers. A numerical example is used to verify the theoretical analysis and to illustrate the design procedure

Design and usability ealuation of social mobile diabetes management system in the Gulf Region

BACKGROUND: The prevalence of diabetes in the Gulf States is one of the highest globally. It is estimated that 20% of the population in the region has been diagnosed with diabetes and according to the International Diabetes Federation (IDF), five of the IDF's "top 10" countries for diabetes prevalence in 2011 and projected for 2030 are in this region. In recent years, there have been an increasing number of clinical studies advocating the use of mobile phone technology for diabetes self-management with improved clinical outcomes. However, there are few studies to date addressing the application of mobile diabetes management in the Gulf region, particularly in the Kingdom of Saudi Arabia (KSA), where there is exponential increase in mobile phone usage and access to social networking. OBJECTIVE: The objective of this paper is to present the design and development of a new mobile health system for social behavioral change and management tailored for Saudi patients with diabetes called Saudi Arabia Networking for Aiding Diabetes (SANAD). A usability study for the SANAD system is presented to validate the acceptability of using mobile technologies among patients with diabetes in the KSA and the Gulf region. METHODS: The SANAD system was developed using mobile phone technology with diabetes management and social networking modules. For the usability study the Questionnaire for User Interaction Satisfaction was used to evaluate the usability aspect of the SANAD system. A total of 33 users with type 2 diabetes participated in the study. RESULTS: The key modules of the SANAD system consist of (1) a mobile diabetes management module; (2) a social networking module; and (3) a cognitive behavioral therapy module for behavioral change issues. The preliminary results of the usability study indicated general acceptance of the patients in using the system with higher usability rating in patients with type 2 diabetes. CONCLUSIONS: We found that the acceptability of the system was high among Saudi patients with diabetes, and ongoing work in this research area is underway to conduct a clinical pilot study in the KSA for patients with type 2 diabetes. The wide deployment of such a system is timely and required in the Gulf region due to the wide use of mobile phones and social networking mediums

Mobile Health (mHealth) in the Developing World: Two Decades of Progress or Retrogression

Mobile healthcare, or mHealth, is one of the key pillars of information and communication technologies for healthcare that consists of telemedicine, telehealth, eHealth, and mHealth. In the past two decades, mobile health has become a transformative concept for healthcare delivery innovations on a global scale. The success was based on the market-driven strategies that utilised the advances in mobile communications, computing, and sensor technologies, especially in recent years. Those market-driven mobile health systems were also closely associated with the global proliferation of smartphones, and based on the correlated usage principle of the smartphone applications for healthcare and wellbeing. However, the global commercial success of the smartphone-based mHealth model was not widely translated into successful scaled-up and tangible healthcare benefits, especially in low- and-middle income countries, compared to the consumer mobile health markets. The numerous healthcare challenges in the developing world remained largely untackled by the existing mobile health systems and models. The much-hyped transformative benefits of these systems remain largely unfulfilled. For two decades since the inception of this concept, the majority of the population in resource-limited healthcare settings still remain in poorer health and live in worsened conditions, with limited if any access to basic healthcare services. The much-hyped mobile health services that promised transforming these fragile and limited healthcare conditions, did not come to wider fruition globally. The COVID-19 pandemic, with its devastating human and economic impact worsened this status. An overview of the origin and the basic principles of mobile health, its current landscape and status in the developing world is presented. The impact of the smartphone-centric model that dominated the landscape of mobile health systems in these countries is discussed, and a critical view on the limitation of this mobile health model adopted widely in these settings is provided

Mobile health (m-Health) for diabetes management

Diabetes is a major health challenge with a global impact regardless of age, country or economic condition. The increased prevalence of diabetes is reaching alarming levels. The necessity and urgency to find innovative care delivery solutions is becoming more important, particularly in the digital age. It is expected in the near future that more people with diabetes, especially the younger generations will be empowered by their smartphones and relevant mobile health (m-Health) innovations, to take more responsibility of their condition. Clinicians and healthcare providers are increasingly likely to assume the role of ‘navigators’ and ‘advisors’ rather than simply the medical gatekeeper for their patients. In this article, we describe the general architecture of current m-Health systems and applications for diabetes management. We also discuss the clinical evidence for impact from these important and innovative approaches to diabetes self-care and management and likely future trends in their usage. The latest statistics indicate that there are more than 1200 diabetes smartphone ‘apps’ and this area is growing exponentially in terms of ideas, technologies, devices and the associated industry. M-Health for diabetes care is now a major business stream for the medical device, mobile phone and IT telecommunication industries with high expectations arising from the potential benefits to be gained by both patients and healthcare providers. However, this potential has not yet been fully developed on the clinical side. This may be due to many factors including the reluctance of clinicians to engage with these technologies due to the lack of clinical evidence for their efficacy, poor adherence of people with diabetes to long-term use of these apps and the reluctance of healthcare funders to reimburse mobile diabetes

Optimizing stability bounds of finite-precision PID controller structures

The paper investigates a recently derived lower bound stability measure for sampled-data controller structures subject to finite-word-length (FWL) constraints. The optimal realization of the digital PID controller with FWL considerations is formulated as a nonlinear optimization problem, and an efficient strategy based on adaptive simulated annealing (ASA) is adopted to solve this complex optimization problem. A numerical example of optimizing the finite-precision PID controller structure for a simulated steel rolling mill system is presented to illustrate the effectiveness of the proposed strategy
