The Santa Catarina State Telemedicine and Telehealth System - STT/SC stores well over 2 million examinations and every month about 20 thousand new imaging exams are sent to the system database. As a significant part of the findings associated to these medical data are stored as text documents, the precise extraction of information is a difficult task. In the healthcare domain it is common to find different terms, some of them appearing as composed expressions, used to represent the same concept, whereas the existence of simple modifiers can turn an expression into another, different concept. This work presents an information retrieval architecture developed for the STT/SC. It consists in a module integrated into the STT/SC and was developed in order to support both experienced and inexperienced users to perform queries. Experiments were performed to evaluate the accuracy of the proposed system in real situations. Results show that the search can be performed more much faster and with acceptable precision.

Can reliable telecardiology be achieved at low bandwidth cost? In response, we propose a detector at the user end so that only beats found to be anomalous are transmitted to a diagnostic center, where all received beats are correctly (re)classified. In this framework, high reliability is achieved by detectors with high sensitivity. Having laid the design framework, we then realize desired high-sensitivity detection using a dictionary learning approach. Specifically, using patient records from the MIT-BIH arrhythmia database, we detect ventricular ectopic beats (VEBs), which are known to be precursors to various serious arrhythmic conditions in the heart. In particular, we achieve a reliability of one undetected VEB in one thousand while saving 78.2% bandwidth using dictionaries with 240 atoms. With larger dictionaries with 420 atoms, we achieve an even higher bandwidth savings of 79.2% while allowing no (less than one in 1766) undetected VEB. Finally, we compare our results with performances a large set of reported heartbeat classifiers, and demonstrate the suitability of our approach in the context of telecardiology.

The aim of this paper is to provide a lightweight approach for early detection of nocturnal epileptic seizures using data from wireless 3-D accelerometer sensors. We use the exponentially weighted moving average algorithm to forecast the current value of the accelerometer measurement, and when the difference between measured and forecasted values is greater than the dynamic threshold on any axis, a notification is transmitted to the base station, which maintains a sliding window of received notifications. When the filling ratio is greater than a predefined threshold, an alarm is triggered by the base station. The proposed approach is intended to improve the performance of existing mobile health detection systems based on the analysis of electroencephalogram (EEG). To reduce their false alarm rate, we seek to correlate detection results from 3-D accelerometer with other physiological parameters through a majority voting. Our experimental results on real dataset collected from the epileptic patient show that our proposed approach is robust against temporal fluctuations and achieves a high level of detection accuracy, which in turn proves the effectiveness of this approach in enhancing the reliability of existing detection approaches based on EEG signal analysis.

The rise in motion-based gaming peripherals has afforded intriguing opportunities for low-cost instrumentation of health-oriented activities. One particular activity, that of physical therapy, is of considerable interest as traditional systems in the area cost on the order of tens of thousands of dollars. However, while recent research has shown that gaming peripherals can deliver high quality instrumentation, non-expert programmers face considerable challenges in delivering robust and accurate instrumentation outside of the lab environment. Furthermore, when one considers how to fuse data across multiple peripherals, the heterogeneity of peripheral performance significantly complicates recording useful data. To that end, this paper seeks to describe our approach for delivering a robust, accurate, and scalable framework for motion-based gaming peripherals, specifically targeted at physical therapy in the clinical and research settings. We describe the principles of our framework and composition of data flow through a variety of illustrative examples. Finally, we conclude with several experimental setups designed to demonstrate the efficacy of the framework drawn directly from our experience in live clinical settings.

The translation or mapping between terminologies in healthcare is one of the ways to achieve semantic interoperability between information systems. Accordingly, we propose a method to assist the translation of terminologies based on the association rules mining in integrated databases containing data encoded with two different terminologies. This method also uses text search (string matching) between terms. The extracted rules proved the correct translation of some terms and when a valid rule could not be extracted, textual search proved to be a good resource. Further work will be undertaken to quantify the efficiency of the method through expert analysis.

Wireless Sensor Networks (WSNs) have recently attracted a lot of attention in the research community because it is easy to deploy them in the physical environment and collect and disseminate environmental data from them. The collected data from sensor nodes can vary based on what kind of application is used for WSNs. Data confidentiality and access control to that collected data are the most challenging issues in WSNs because the users are able to access data from the different location via ad-hoc manner. Access control is one of the critical requirements to prevent unauthorised access from users. The current access control models in information systems cannot be applied straightforwardly because of some limitations namely limited energy, resource and memory, and low computation capability. Based on the requirements of WSNs, we proposed the Break-The-Glass Access Control (BTG-AC) model which is the modified and redesigned version of Break-The-Glass Role-Based Access Control (BTG-RBAC) model. The several changes within the access control engine are made in BTG-RBAC to apply and fit in WSNs. We developed the BTG-AC model in Ponder2 package. Also a medical scenario was developed to evaluate the BTG-AC model for medical data in WSNs. In this paper, detail design, implementation phase, evaluation result and policies evaluation for the BTG-AC model are presented. Based on the evaluation result, the BTG-AC model can be used in WSNs after several modifications have been made under Ponder2 Package.

In commercial ultrasound systems, the transmit module typically generates the time delayed excitation pulses to steer and focus the acoustic beam. However, the ultrasound transmitter module in these systems has limited access to medical ultrasound researchers. In this paper, we have presented the development of a programmable architecture for 8-channel ultrasound transmitter for medical ultrasound research activities. The proposed architecture consists of 8 transmit channels and Field Programmable Gate Array (FPGA) based configurable delay profile to steer acoustic beam, transmit frequency and pulse pattern length depending on the medical application. Our system operates in pulse-echo mode, with ultrasound transmit frequency up to 20 MHz, excitation voltage up to 100 Vpp, and individual channel control with single high speed Serial Peripheral Interface (SPI). Pre-calculated delay profiles per scanline are generated in Matlab, based on physical parameters of 8 element linear transducer array which are used to steer and focus the ultrasound beam. An experiment is carried with our transmit module to transmit ultrasound into gelatin phantom, acquired echoes and processed for B-mode imaging. The results show that this transmit platform can be used for ultrasound imaging researches and also for medical diagnosis.

We present the results of the third phase in a three part study developing an application to reduce obesity levels in adolescents with a mobile fitness application that encourages youth to engage in fitness activity by providing social networking tools to facilitate motivation. In the first phase, we studied effecting positive attitudinal changes towards fitness. The second phase studied physical improvements with the application in our target group. This third phase tests the efficacy of the socialization tools in our application for motivating both positive attitudinal changes and physical improvements towards fitness. The application contained thirteen distinct exercises that subjects could engage in using sensors on the mobile devices to unbiasedly measure progress. The socialization tools to encourage fitness engagement allowed for such activities as friending, sharing progress and collaboratively exercising with friends either in person or remotely. The study participants were adolescents age 14 to 15 with 20 subjects in an experimental group that used the fitness application and 15 control subjects that did not. The study ran for eight weeks with the results indicating both positive attitude changes towards fitness exercises and body-mass index (BMI) improvements in fitness levels correlated to socialization interests/activities for the subjects using the application, while the control group showed no such correlation of fitness level improvement.
