Monitoring BP Through a Smartphone Application is Possible Now, Check it Out Here!

However, the app still needs to be validated in a standard regulatory test

Researchers have developed a novel blood pressure (BP) application that can give accurate readings using an iPhone, without requiring any special equipment.

Developed by the Michigan State University researchers, the new “iPhone X” app measures BP via the ‘oscillometric finger pressing method’, or ‘peek and pop’ that enables users looking to open functions and apps with a simple push of their finger.

The user presses her fingertip on both the front camera and screen to increase the external pressure of the underlying artery, while the application measures the resulting variable-amplitude blood volume oscillations via the camera and applied pressure via the strain gauge array under the screen.

The application, featured in the journal Scientific Reports, also visually guides the fingertip placement and actuation and then computes BP from the measurements just like many automatic cuff devices.

When tested, along with a finger cuff device, against a standard cuff device, the app yield indicated that cuff-less and calibration-free BP monitoring may be feasible with many existing and forthcoming smartphones, the researchers said.

“By leveraging optical and force sensors already in smartphones for taking ‘selfies’ and employing ‘peek and pop’, we’ve invented a practical tool to keep tabs on blood pressure,” said lead author Ramakrishna Mukkamala, Professor at MSU.

“Such ubiquitous blood pressure monitoring may improve hypertension awareness and control rates, and thereby help reduce the incidence of cardiovascular disease and mortality,” he added.

If things keep moving along at the current pace, an app could be available in late 2019, Mukkamala said.

However, the app still needs to be validated in a standard regulatory test.

“But because no additional hardware is needed, we believe that the app could reach the society faster,” he noted.

While high blood pressure is treatable with lifestyle changes and medication, only around 20 per cent of people with hypertension have their condition under control. This invention gives patients a convenient option and keeping a log of daily measurements would produce an accurate average. (IANS)

Micro-blogging Site Twitter to Audit Developers Using Data From App

Twitter says it suspended 1,62,000 apps in the second half of 2018, showing it is willing to play hardball with developers that endanger its ecosystem

Micro-blogging site Twitter has decided to audit app developers who use data from its platform, as business and research boosting tools to make sure it gets paid for the information delivered.

Starting June 19, developers that use recent tweets from or mention a user more than 100,000 times per day, will have to submit their apps to Twitter for review.

“The goal is ensuring that our platform is safe and promoting the privacy and safety of our users, and providing a level playing field commercially,” TechCrunch quoted Yoel Roth, Head of site integrity, Twitter as saying on Tuesday.

Developers found to be violating Twitter’s policies would be booted from the platform, while those who fail to file for review will be capped at 100,000 requests per day for the user timeline and mentions application programming interfaces (APIs) of Twitter.

“We’re fundamentally different than other platforms that have APIs since almost everything that happens on our service is public,” Roth explained.

Developers who use Twitter data as business tools for customer services or social media monitoring, will have to pay and enter a commercial licencing agreement with the platform with an undisclosed custom price-range based on usage.

“Twitter refused to even specify the range those prices fall into, which won’t win it any extra trust,” the report said.

If a developer in question presents legitimate consumer-use cases, like running a third-party Twitter client or doing research, it will be granted free access to the API at the same rate they have today.

Twitter says it suspended 1,62,000 apps in the second half of 2018, showing it is willing to play hardball with developers that endanger its ecosystem, the report added. (IANS)
