Blockchain Makes Strides in Ensuring Data Validity

Published

on

Researchers at the University of California, San Francisco have made a proof-of-concept technique to ensure the integrity of data in different clinical trials utilizing blockchain. Currently, this system creates the immutable audit trial, which makes it easier to find out whether or not the data was tampered with or if the data excluded information about diminishing side effects.

Blockchain technology utilizes the old computer science method called hashing. Hashing creates a rare digital signature for particular blocks of data. These hashes accumulate as new data is changed or entered, and as a result,  information blocks build on top of one another sequentially. The resulting “blockchain” makes one audit trail for the regulators, which is easy to validate and decipher, without even looking at the data.

For example, Daniel Wong is a Ph.D. student in Biological & Medical Informatics at the University of California, San Francisco. He has built this type of system to operate through the web portal. As data is changed or entered within the given trial, the information about the participants, timestamp, receiver, the sender, and file attachments with data accumulate together with the hash from the last data block. While most blockchain applications are decentralized, this new clinical trial prototype relies on containing the regulator along with centralized authority. This technique is used by organizations such as the U.S. Food and Drug Administration.

Moreover, data that includes adverse events will be reported to a regulatory agency, which will cause an increase in the efficiency and safety of the clinical trials. While the older version of blockchain created allowances for the data entry or some other mistakes to be error-free, new data will be appended to an existing chain in this decentralized form of blockchain, without having to remove existing information. Now more than ever, it will be extremely clear if data has been corrupted or altered to affect the results of the trial.

In conclusion, blockchain technology might enable trials to be examined under some challenging conditions and will open doors to data exchanges which are secure, efficient, and transparent for the researchers as well as the public. Ultimately, a decentralized version of blockchain has the ability to impact not just researchers but also the public as a whole.

Walmart’s same-day delivery offers fresh produce, frozen and refrigerated foods. You can use the application on your smartphone or access it on the website. Fees are $9.99 per order and offer other memberships that can be used nationwide. It could be something to consider if using the app at least once per month.
Walmart offers a wide variety of products, and because they don’t outsource their delivery service, the prices are the same as they are in the store.

Instacart

Instacart is a grocery delivery service that partners with grocery stores to provide delivery from various markets. Customers can expect a wide variety of products to suit all dietary needs.
Some grocery store chains like Kroger have partnered with Instacart to directly provide grocery delivery services through their website or app that is easy for others to use.
Instacart has optional memberships, and delivery starts at $3.99 per order. The application offers same-day delivery.
Instacart personal shoppers can text you while picking your order if any substitutions are needed. You can contact Instacart support through their email or app.

Shipt

Similar to Instacart, Shipt is a grocery delivery service that partners with grocery store chains offering delivery from a variety of stores to help meet their customers’ dietary needs.
Locations that Shipt delivers to are select metro areas, mostly across the Eastern United States, and offers same-day delivery.
This application is unique in that it requires a membership to have access to their services. In addition, Target grocery delivery is offered exclusively through Shipt.

Kroger

Kroger is partnered with Instacart for its grocery delivery service, but you can place your order through the Kroger app or website. This ensures that you pay the same price as you would in the store or grocery pickup. Kroger also the ship-to-home option in which certain non-perishable foods and household products can be ordered online and shipped to your home. Fees for the Kroger app are $9.95 per order. The app offers same-day delivery and offers its services nationwide. 

Whole Foods

Whole Foods Market offers customers various organic and natural products with selections, including vegan, gluten-free, and paleo. Since Whole Foods is owned by Amazon, Whole Foods works just like the Amazon Fresh program.
Products selected for delivery may still be marked up compared with in-store prices. Locations for delivery are select large cities, and you can use the app through the Amazon website.

Portable X-Ray Receives FDA Clearance for COVID Testing

Published

on

New forms of COVID-19 testing continue to emerge as companies use innovative techniques to determine if an individual could have the virus. From CRISPR testing approval from the FDA to an automated robot conducting COVID-19 testing, a new method from Aspenstate has just been announced.

A lightweight, portable X-ray system from Aspenstate known as the AiRTouch has received FDA clearance. This form of testing could be beneficial for quickly obtaining chest X-rays from potential COVID-19 patients. The AiRTouch weighs 5.5 pounds (2.5 Kg) and looks like a large touchscreen digital camera. The device takes a picture with a push of a button and can wirelessly transfer the images to a clinical image storage system or PACS without a computer. The battery from AiRTouch can charge within two hours and can obtain up to 300 exposures per charge.

This portable X-ray system could be useful for quickly obtaining chest X-rays of COVID-19 patients.  According to the company, its portability has already made it useful in drive-through screening centers in South Korea

“Our clients have noticed a dramatic increase in capacity and the ability to move patients through quickly and efficiently,” David Lee, Vice President and COO of Aspenstate, stated.

Lee went on to say that the device is very simple to use with the integrated software, and portable features allow the use of the device outside of conventional X-ray resources. The company believes the AiRTouch for chest X-rays for COVID-19 could also be used in urgent care facilities, ambulances, sports medicine, extremities, dental, and veterinary settings

Safe COVID-19 Testing Performed by Automated Robot

Published

Medical professionals testing people for COVID-19 usually involves performing a throat swab to collect a sample for processing. Clinicians that are collecting COVID-19 samples from individuals must wear an entire package of personal protective equipment (PPE) that can be quite uncomfortable when worn for long periods. Since the expansion of test sampling is now being conducted outside of clinical facilities and with temperatures rising, wearing protective gear can become difficult for clinicians.

In Denmark, a team of robotic engineers at the University of Southern Denmark have designed a machine that can conduct throat swabs automatically without a human clinician present in the facility. The robot reaches into the throat and moves a swab against the selected tissue within. After the sample is collected, it stores the swab into a glass jar and seals the top shut.  

The robot was trained to be gentle, and volunteers who have already been swabbed by the device have reported no discomfort. Further trials are needed to confirm the efficiency of the new machine and to ensure that no malfunction can occur. To help market and manufacture the new robot, the engineers that developed it have started up a company called Lifeline Robotics. The engineers hope to have devices testing people for COVID-19 as early as late June, but the advanced technology is sure to be useful when the pandemic is over. 

Here are some videos to demonstrate how the machine works:
