A survey on ultra wideband and ultrasonic communication for body area networks

Emergence of implantable and wearable medical sensors for patient monitoring, diagnosis as well as cure has helped in the development of body area networks (BANs). For networking of these implantable and wearable devices, an appropriate choice of radio technology and communication methodology has to be made. Ultra wideband (UWB) has been identified as a solution for wireless body area networks (WBANs) in IEEE 802.15.6, but there are issues to be addressed such as attenuation inside body for implantable devices, energy efficient networking with low heat dissipation and others. Ultrasonic communication although an emerging technology promises better propagation inside body in watery media. It is known to be used without much health hazard in medical applications. This paper compares and evaluates the above two technologies for WBAN. It provides an extensive survey of existing work on UWB and ultrasonic communication for body area networks and highlights the unaddressed research challenges in using UWB and ultrasonic for WBAN applications.

When Medicare patients move, healthcare spending changes

Body: 

When healthcare spending varies widely from one geographical region to another, including for pricey procedures like imaging exams, which variable is more to blame—provider choices or patient preferences?

Both, and in about equal measure, according to researchers at the Massachusetts Institute of Technology who crunched the numbers on millions of Medicare patients who relocated from one place to another.

MIT economist Heidi Williams, PhD, a co-author of the study, tells MIT News that some geographic spending variations may be explained by provider populations being more skilled at certain procedures—and thus more inclined to order them—in some areas than in others.

The researchers further found that, when Medicare enrollees relocate, most of their healthcare spending happens within the first year after the move.

Telemedicine for Developing Countries

Background: Developing countries need telemedicine applications that help in many situations, when physicians are a small number with respect to the population, when specialized physicians are not available, when patients and physicians in rural villages need assistance in the delivery of health care. Moreover, the requirements of telemedicine applications for developing countries are somewhat more demanding than for developed countries. Indeed, further social, organizational, and technical aspects need to be considered for successful telemedicine applications in developing countries. Objective: We consider all the major projects in telemedicine, devoted to developing countries, as described by the proper scientific literature. On the basis of such literature, we want to define a specific taxonomy that allows a proper classification and a fast overview of telemedicine projects in developing countries. Moreover, by considering both the literature and some recent direct experiences, we want to complete such overview by discussing some design issues to be taken into consideration when developing telemedicine software systems. Methods: We considered and reviewed the major conferences and journals in depth, and looked for reports on the telemedicine projects. Results: We provide the reader with a survey of the main projects and systems, from which we derived a taxonomy of features of telemedicine systems for developing countries. We also propose and discuss some classification criteria for design issues, based on the lessons learned in this research area. Conclusions: We highlight some challenges and recommendations to be considered when designing a telemedicine system for developing countries....

REDAlert+

Each year, thousands of people in developing countries die due to delayed medical response. A common complaint is that emergency vehicles respond late and when they reach the hospital, precious time is lost in understanding the patient trauma before the doctors can get to work. A large number of deaths can be prevented if medical services can be provided to the victims in time, which can happen when the emergency wing of a hospital has advance information about the trauma before the patient reaches the hospital. Most hospitals lack communication infrastructure that allows them to coordinate with emergency vehicles bringing patients to hospital. In developed countries, Vehicular Ad-hoc Networks (VANETs) are prevalent. These networks use vehicles as mobile nodes to create a small-interconnected network on the road. A mobile application based on the principle of VANETs in combination with wireless communication and database management has been devised, that when integrated with emergency vehicles and hospitals, provides a seamless medical response system at times of an emergency.

About Me

As a Dermatologist and Informatician my research mainly involves application of bioinformatics techniques and tools in dermatological conditions. However my research interests are varied and I have publications in areas ranging from artificial intelligence, sequence analysis, systems biology, ontology development, microarray analysis, immunology, computational biology and clinical dermatology. I am also interested in eHealth, Health Informatics and Health Policy.
