A Smartphone App to Test for Minimal Hepatic Encephalopathy

Presented: Monday, November 12, 1:45 pm, Liver Meeting®, Hynes Convention Center

BOSTON, Nov. 11, 2012 /PRNewswire/ -- Minimal hepatic encephalopathy (MHE), which is often found in patients with cirrhosis, is difficult to diagnose. This is an important issue because MHE is associated with poor quality of life, progression to severe disease, unemployment, and traffic accidents and can be treated if it is diagnosed. A smartphone app for Stroop task, which is used to evaluate psychomotor speed and cognitive flexibility, could be used to screen for MHE.

Researchers at Virginia Commonwealth University and McGuire Veterans Medical Center attempted to validate the Stroop task app against standard diagnostic tests for MHE. To do so, they studied 125 patients with cirrhosis. Some of those patients did and some (82 of 125) did not have overt hepatic encephalopathy (OHE). Patients with cirrhosis were matched with a control group by age and education. All were tested with both the smartphone app and the psychometric hepatitis encephalopathy battery. A subgroup was tested twice (test-retest group) to assure test-retest reliability.

The outcomes of the test were compared to those of the control group, patients with cirrhosis with OHE, and patients with cirrhosis without OHE. MHE was seen in 44 percent of all patients and 40 percent of those patients who did not have OHE. The app performance was worse in patients with cirrhosis, especially those with OHE and advanced disease, compared to controls.

The test-retest proved the app to be reliable, and a cut-off described was very sensitive for the rapid diagnosis of MHE and cognitive dysfunction. The app could be administered and interpreted within 5 minutes by medical assistants and could play an important role in the rapid and objective screening for this condition in the clinic. According to Dr. Bajaj, "These findings open up a new chapter of point-of-care testing for MHE that can be done in the clinics. We would like to and are in the process of studying the functionality of this app before and after TIPS placement and therapy as well as in patients with concomitant psychoactive medicines."

Dr. Bajaj also noted that, "The results were better than expected when you consider that most of our patients had relatively little exposure to smartphones -- only 30 percent were familiar with smartphones. This shows that the platform for giving the test remains valid despite the initial unfamiliarity of patients. Researchers concluded that the Stroop task smartphone app is a quick, reliable, valid, and inexpensive diagnostic process.

Abstract title: 
The Stroop smartphone app is a short and valid screening tool for minimal hepatitis encephalopathy

Many organizations adopt DevOps to reduce cycle times and deliver software faster; some take on DevOps to drive higher quality and better end-user experience; others look to DevOps for a clearer line-of-sight to customers to drive better business impacts. In truth, these three foundations go together. In this power panel at @DevOpsSummit 21st Cloud Expo, moderated by DevOps Conference Co-Chair Andi Mann, industry experts will discuss how leading organizations build application success from all...
Most of the time there is a lot of work involved to move to the cloud, and most of that isn't really related to AWS or Azure or Google Cloud. Before we talk about public cloud vendors and DevOps tools, there are usually several technical and non-technical challenges that are connected to it and that every company needs to solve to move to the cloud. In his session at 21st Cloud Expo, Stefano Bellasio, CEO and founder of Cloud Academy Inc., will discuss what the tools, disciplines, and cultural...
The “Digital Era” is forcing us to engage with new methods to build, operate and maintain applications. This transformation also implies an evolution to more and more intelligent applications to better engage with the customers, while creating significant market differentiators. In both cases, the cloud has become a key enabler to embrace this digital revolution. So, moving to the cloud is no longer the question; the new questions are HOW and WHEN. To make this equation even more complex, most ...
DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain.
As DevOps methodologies expand their reach across the enterprise, organizations face the daunting challenge of adapting related cloud strategies to ensure optimal alignment, from managing complexity to ensuring proper governance. How can culture, automation, legacy apps and even budget be reexamined to enable this ongoing shift within the modern software factory?
