Applied Bimatics - An Informatics & eHealth Blog

I am a clinician with a passion for informatics. This blog is about my eHealth journey exploring interoperability in Electronic Medical Records (EMR/EHR), Patient Safety, Pharmacovigilance, Data Analytics, Clinical Research and Bioinformatics in a clinical context. Comparing Canadian, Indian and Middle Eastern healthcare systems and services. Join our open facebook group here: https://www.facebook.com/groups/clinical.bioinformaticians/


eHealth User Interface Design for Seniors

Many of the open-source PHR systems have poor user interfaces (UI) by any standards while older adults have specific interface requirements. Credible research on the special interface requirements of elderly is still hard to find.

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.

X-ray vision: Coming soon to a smartphone near you

Body: 

You don’t need to be Superman to have X-ray vision these days, according to the makers of Walabot, a handheld 3D-imaging device that plugs into Android smartphones.

The product is based on the parent technology Vayyar, which was originally designed for mobile breast cancer screening, but the company believes the product has unlimited potential for use in other areas of everyday life.

“Looking into skin tissue is difficult,” Vayyar marketing director Malcolm Berman told tech website Digital Trends. “If you can see through that, then you can see through many other things.”

The device uses radio frequency technology—the same technique used in Wi-Fi, mobile networks and radar systems—to create 3D images of the internal structures of walls, objects and other materials.

“We can see through objects and see into objects,” Berman said. “This could enable you to check alcohol percent in vodka or fat level in milk, it can also detect speed, track targets, and see where people are moving. You can look inside walls and see the foundation of buildings. You could use it to check how much water is in soil and avoid over-watering crops. It could enhance robotic vision, enabling drones or robots to sense their environment.”
