blood vessel repairs

Scientists led by Nanyang Technological University, Singapore (NTU Singapore) developed a device that offers a quicker and less invasive way to seal tears and holes in blood vessel repairs, using an electrically activated glue patch applied via a minimally invasive balloon catheter.

The benefit of this device is to replace the need for open or keyhole surgery to patch up or stitch together internal blood vessel repairs and defects.

“The system that we developed is potentially the answer to the currently unmet medical need for a minimally-invasive technique to repair arteriovenous fistulas (an abnormal connection between an artery and a vein) or vascular leaks, without the need for open surgery. With Voltaglue and the catheter device, we open up the possibility of not having to make surgical incisions to patch something up inside – we can send a catheter-based device through to do the job,” Assoc Prof Steele said in a statement.

After inserting the catheter into an appropriate blood vessel, the glue patch – nicknamed ‘Voltaglue’ – can be guided through the body to where the tear is located and then activated using retractable electrodes to glue it shut in a few minutes, all without making a single surgical cut.

Patented by NTU and Massachusetts Institute of Technology (MIT) scientists, Voltaglue is a new type of adhesive that works in wet environments and hardens when a voltage is applied to it.

The catheter device that deploys Voltaglue is jointly developed by Associate Professor Terry Steele from the NTU School of Materials Science and Engineering, former NTU PhD student Dr Manisha Singh, now at MIT, and Associate Professor Ellen Roche from the Department of Mechanical Engineering and Institute for Medical Engineering and Science at MIT, USA.

The device is the first proof-of-concept application of Voltaglue in a medical setting since it was invented by Assoc Prof Steele in 2015.

The team showed in lab experiments on a pig’s heart that the Voltaglue patch can be safely and effectively administered in a variety of situations, including withstanding the high pulsatile pressure of blood in arteries like the aorta.

The device was used to close a 3mm defect in an explanted pig aorta connected to a mock heart under continuous flow of blood of 10ml per minute.

Drawing on their findings, the researchers foresee that the catheter device may someday be used to deliver patches to repair birth defects such as holes in the wall of the heart.

AI cancer diagnosis

The U.S. Food and Drug Administration (FDA) granted Breakthrough Device Designation to Ibex Medical Analytics, a specialist in AI-powered cancer diagnostics, which will help fast track the clinical review and regulatory approval of its platform.

Granting such approval is given to technologies that have the potential to provide more effective treatment or diagnosis of life-threatening diseases.

The designation enables close collaboration with, and expedited review by the FDA, and provides formal acknowledgement of the Galen platform’s utility and potential benefit as well as the robustness of Ibex’s clinical program.

Oncology treatments

According to the National Cancer Institute, approximately 39.5 percent of men and women will be diagnosed with cancer at some point during their lifetimes (based on 2015–2017 data).

“In 2020, an estimated 16,850 children and adolescents ages 0 to 19 will be diagnosed with cancer and 1,730 will die of the disease,” the institute noted.

An estimated 1,806,590 new cases of cancer will be diagnosed in the United States in 2020, it noted, and 606,520 people will die from the disease.

“Oncology treatments have made great strides, but to save more lives it is also essential to see technological advances in cancer diagnostics. Enhancing the accuracy of cancer diagnosis and improving the efficiency for the pathologist is paramount to improving quality and affordability of cancer care,” David Shulkin, MD, advisor to Ibex Medical Analytics said.

AI cancer diagnosis platform role

“Ibex’s AI platform has demonstrated success in helping pathologists worldwide improve care for patients with cancer. This FDA designation is an important step forward in making this technology broadly available in the United States,” David added.

That said, pathologists play an important role in the detection and diagnosis of disease, with their assessment being vital for correct treatment decisions in cancer care.

However, a rise in cancer prevalence and advances in personalized medicine have resulted in growing diagnostic complexity that significantly increases pathologists’ workloads.

As such, Ibex’s Galen platform uses Strong AI algorithms to help pathologists improve the quality of cancer diagnosis, implement real-time quality control, reduce diagnosis time, and boost productivity. It has already demonstrated outstanding outcomes in clinical studies and is deployed in labs worldwide where it is used as part of everyday clinical practice.

Joseph Mossel, chief executive officer and co-founder of Ibex Medical Analytics, said: “We are honored to have been granted the Breakthrough Device Designation. Ibex is committed to providing world class tools for pathologists to ensure every patient receives a timely and correct diagnosis, while supporting pathology labs and health systems to increase efficiency and accuracy. Our Strong AI technology is already in clinical use globally, making a real impact on patient care. We are proud to work closely with the FDA and look forward to continuing to collaborate with the agency as we accelerate our clinical program in the United States.”

Sputnik-V

Controversy has been the main headline stuck to Russia’s Sputnik V COVID-19 vaccine, with many countries either doubting its efficacy levels or brushing it off due to political tensions between western countries and Russia.

In parallel, Russia hasn’t done a good job marketing the drug since it was named after the Soviet Union’s and the world’s first artificial satellite launched into space back in 1957.

But still the Russian vaccine persisted and remains to be administered to people all around the world as we speak.

With that in mind, the Russian Direct Investment Fund (RDIF, Russia’s sovereign wealth fund) announced on Thursday data of the Ministry of Health of the Kingdom of Bahrain on the Russian Sputnik V coronavirus vaccine confirming its safety and high efficacy during the vaccination campaign in the country.

The efficacy study was conducted in Bahrain in accordance with WHO guidelines involving more than 5,000 subjects. Overall efficacy beyond 14 days after administering the second dose was estimated at 94.3 percent.

Analysis is based on the data collected between February and early May 2021.

“Sputnik V has demonstrated efficacy of 94.3 percent and high safety confirming the data collected in a number of other countries where it is used to protect the population against coronavirus. The Russian vaccine is an important part of Bahrain’s diversified national portfolio. Use of Sputnik V is making a significant contribution in mitigating the spread of coronavirus, resuming normal life and economic activity,” Kirill Dmitriev, CEO of the Russian Direct Investment Fund (RDIF), said in a statement.

The data of the Ministry of Health also demonstrates that 98.6 percent of all COVID-19 cases 14 days after receiving the second dose were mild among those vaccinated with Sputnik V.

Vaccination data indicates high safety of Sputnik V:

  • No serious adverse events associated with vaccination;
  • No deaths related to the vaccination;
  • No cerebral vein thrombosis (CVT) cases after vaccination.

“Our data has confirmed the high efficacy and safety of Sputnik V during its use in Bahrain. This vaccine is one of a number of approved vaccines made available free of charge to citizens and residents in the Kingdom. Sputnik V continues to play an important role in the Kingdom’s ongoing and successful vaccination campaign, with 81 percent of the eligible population vaccinated so far,” Faeqa Saeed Al-Saleh, Bahrain’s Minister of Health, highlighted. 

Sputnik V has a number of key advantages:

  • Efficacy of Sputnik V is 97.6 percent based on the analysis of data on the coronavirus infection rate among those in Russia vaccinated with both components of Sputnik V from December 5, 2020, to March 31, 2021;
  • The vaccine is based on a proven and well-studied platform of human adenoviral vectors, which cause the common cold and have been around for thousands of years.
  • Sputnik V uses two different vectors for the two shots in a course of vaccination, providing immunity with a longer duration than vaccines using the same delivery mechanism for both shots.
  • The safety, efficacy, and lack of negative long-term effects of adenoviral vaccines have been proven by more than 250 clinical studies over two decades.
  • There are no strong allergies caused by Sputnik V.
  • The storage temperature of Sputnik V at +2+8 C means it can be stored in a conventional refrigerator without any need to invest in additional cold-chain infrastructure.
