Micro Data: Wearable Devices Contribution to Improved Chronic Disease Management

Issues involving chronic disease prevention and management (CDPM) are prevalent in today's aging society, and suggestions for improvement are essential to treat this patient demographic effectively. This article addresses the use of wearable devices for the medical community to improve CDPM by relying on the accumulation of micro data. For the patient, we recognize that these devices can be an effective tool to facilitate real-time monitoring of their vital signs and activity levels. With real-time monitoring and earlier responses, individuals can benefit by preventing, delaying or reducing exacerbations of chronic diseases. Use of these devices also has great benefit to the person and has the potential to decrease the individual's emergency room visits, hospital admissions and re-admissions. As patients and their healthcare providers work together to identify cumulative trends in their micro data, transitions in care planning will be enhanced, further contributing to improved chronic disease management.

Facegram – Objective quantitative analysis in facial reconstructive surgery

Publication date: June 2016
Source:Journal of Biomedical Informatics, Volume 61
Author(s): Ana Gerós, Ricardo Horta, Paulo Aguiar
Evaluation of effectiveness in reconstructive plastic surgery has become an increasingly important asset in comparing and choosing the most suitable medical procedure to handle facial disfigurement. Unfortunately, traditional methods to assess the results of surgical interventions are mostly qualitative and lack information about movement dynamics. Along with this, the few existing methodologies tailored to objectively quantify surgery results are not practical in the medical field due to constraints in terms of cost, complexity and poor suitability to clinical environment. These limitations enforce an urgent need for the creation of a new system to quantify facial movement and allow for an easy interpretation by medical experts. With this in mind, we present here a novel method capable of quantitatively and objectively assess complex facial movements, using a set of morphological, static and dynamic measurements. For this purpose, RGB-D cameras are used to acquire both color and depth images, and a modified block matching algorithm, combining depth and color information, was developed to track the position of anatomical landmarks of interest. The algorithms are integrated into a user-friendly graphical interface and the analysis outcomes are organized into an innovative medical tool, named facegram. This system was developed in close collaboration with plastic surgeons and the methods were validated using control subjects and patients with facial paralysis. The system was shown to provide useful and detailed quantitative information (static and dynamic) making it an appropriate solution for objective quantitative characterization of facial movement in a clinical environment.

A quasi-static 3D model of wheelchair propulsion

The use of theoretical models is an alternative for studying the configuration of manual wheelchairs. Richter and Morrow proposed one of the theoretical models used to study propulsion in manual wheelchairs. However this analytical model is limited to use in the sagittal plane. This article presents a quasi-static 3D model that could examine wheelchair propulsion and provide performance analysis during 3D motion. The 3D model takes into account parameters such as axial forces on the hand, the lateral distance between the shoulder joint and the centre of the axis of the propulsion wheel and the angles of inclination of the propulsion wheel (camber angle). The results obtained using our 3D model of wheelchair propulsion show the influences of the lateral distance between the shoulder joint and the axis of the propulsion wheel as well as the effects of the camber angle in the shoulder and elbow joints.

Health IT vendors and the academic community: The 2014 ACMI debate

Publication date: April 2016
Source:Journal of Biomedical Informatics, Volume 60
Author(s): Alexa T. McCray, John Glaser, Ross Koppel, Curtis P. Langlotz, Jonathan Silverstein
The American College of Medical Informatics (ACMI) periodically hosts a debate at the American Medical Informatics Association (AMIA) fall symposium on a timely topic in biomedical informatics. In 2014 a panel of ACMI fellows debated the following proposition: “The lack of interaction and collaboration between health IT vendors and academic clinical informatics units is stifling innovation and will continue to have a detrimental effect on the evolution of commercial products.” Debaters disagreed on the level of interaction and collaboration between the health IT sector and academia and disagreed on whether and by whom innovation was actually taking place. While collaboration between industry and academia was seen as desirable by all of the debaters, there was an acknowledgment that these groups have notably different roles and responsibilities. There was consensus that a path forward should be found, and that AMIA itself has an important role to play in effecting this.

What drives electronic word-of-mouth on social networking sites? Perspectives of social capital and self-determination

Publication date: November 2016
Source:Telematics and Informatics, Volume 33, Issue 4
Author(s): Tien Wang, Ralph Keng-Jung Yeh, Charlie Chen, Zorikto Tsydypov
An increasing number of customers make purchase decisions according to social media referrals. Social-network-based communication is becoming a necessity for companies to stay competitive. However, using social networks to effectively promote electronic word-of-mouth (eWOM) remains challenging. Managers in general are unfamiliar with the key factors that can encourage online social network members to engage in eWOM. This study used social capital and self-determination theories to identify three social capital factors and two individual factors on eWOM. A survey of 238 social network users was conducted to determine the relative influence of these five factors on eWOM among the users. The partial least square analysis results indicate that tie strength and innovativeness directly influence eWOM in virtual social networks. Trust, shared language, and voluntary self-disclosure do not exhibit a significant influence. Theoretical and practical implications of the five factors for promoting eWOM in social networks are drawn from these findings.

Diagnosis of Breast Cancer Using Intelligent Information Systems Techniques

Breast cancer is the second leading cause of cancer deaths in women worldwide. Early diagnosis of this illness can increase the chances of long-term survival of cancerous patients. To help in this aid, computerized breast cancer diagnosis systems are being developed. Machine learning algorithms and data mining techniques play a central role in the diagnosis. This paper describes neural network based approaches to breast cancer diagnosis. The aim of this research is to investigate and compare the performance of supervised and unsupervised neural networks in diagnosing breast cancer. A multilayer perceptron has been implemented as a supervised neural network and a self-organizing map as an unsupervised one. Both models were simulated using a variety of parameters and tested using several combinations of those parameters in independent experiments. It was concluded that the multilayer perceptron neural network outperforms Kohonen's self-organizing maps in diagnosing breast cancer even with small data sets.

Up and running with activiti in 20 minutes

Activiti-ExplorerImage Credit: Unsplash @ pixabay

Activiti is a BPMN automation tool that makes communication between business analyst and the developers easy. Activiti has a web-based graphical interface for business analysts to prepare workflows that can be enhanced by developers adding Java code using an Eclipse plugin. It has a lightweight engine that can be embedded in Java applications to deploy the workflow and an explorer for deploying the process definitions online. Activiti also has a REST interface.

Activiti uses an in-memory database by default. Installation requires Java and servlet container like Tomcat. I have created a puppet script to automate activity installation in a virtual machine. The script installs activity Explorer and the REST interface with the mySQL database. if you want to connect to an external database you can make the necessary changes in the properties file within the code folder.

Installation instructions for Activiti

There are ways of creating a virtual Linux machine in your laptop (Mac and Windows). Virtualization leaves your operating system untouched, and the virtual machine can be removed without a trace after use. Without further ado, you can install this in 5 easy steps using my puppet script.

1. Install VirtualBox.
2. Install Vagrant.
3. Download and extract the zip file below to any folder.

RM1


4. Windows users double-click run.bat. Mac users run the following command from the download folder.
vagrant up

(The script takes approximately 10 minutes to setup the machine. However, no response is needed from your part. An internet connection is required.)
5. Access in your browser:

  • Access Activiti at http://localhost:8001/activiti-explorer
  • Access REST interface at http://localhost:8001/activiti-rest/services

To stop the machine on windows, use stop.bat and on Mac:

vagrant suspend

You can restart the machine as step 4 above. Restarting the machine does not require an internet connection.

If you want to destroy (uninstall) the virtual machine, use the following command in the script folder.

vagrant destroy --force

Feel free to fork and improve this script on GitHub. Pull-requests are welcome. Join E-Health on GitHub if you want direct write access to the repository.

Is radiology ready for virtual reality?

Body: 

Modern healthcare is about to enter a new era in which doctors can not only view 3D models using images from MRI, ultrasound and other modalities, but they can actually reach out and “touch” those images, tour patients’ anatomical structures and perform mock operations using virtual reality technology.

This according to an article recently published online in the Wall Street Journal highlighting the rapid advancement of virtual reality capabilities and the growing technology’s potential impact on healthcare.

“[Virtual reality] gives a very immersive way of looking at all this data,” Sandeep Gupta, of GE Global Research, told the WSJ. “Doctors may be able to see which brain regions are affected by a neurodegenerative disease, for example, or which neural pathways information and signals are flowing through.”

The biggest hurdle to unlocking the future possibilities of medical virtual reality, however, could be the doctors themselves, who have been slow to embrace the emerging technology.
