Researchers at Sarasota Memorial Health Care System today announced the start of the EASE (Exhale Airway Stents for Emphysema) Trial, an international, multi-center clinical trial to explore an investigational treatment that may offer a significant new, minimally-invasive option for those suffering with advanced widespread emphysema. The study focuses on a procedure called airway bypass that involves creating pathways in the lung for trapped air to escape and in turn, relieve emphysema symptoms including shortness of breath.
Emphysema is a chronic, progressive, and irreversible lung disease characterized by the destruction of lung tissue. The loss of the lungs' natural elasticity and the collapse of airways in the lung combine to make exhalation ineffective, leaving the emphysema sufferer with hyperinflation because they can’t get air out of their lungs. With hyperinflation, breathing becomes inefficient and the patient is always short of breath. Even the most nominal physical activities become difficult for emphysema patients and many become dependent on oxygen therapy.
“We are excited to be part of this study because currently treatment options for the emphysema patients are very limited and many patients have a very poor quality of life,” states Kirk Voelker, MD, principal investigator of the study at Sarasota Memorial Hospital. “By creating new pathways for airflow with the airway bypass procedure, we hope to reduce hyperinflation and improve lung function. If patients can breathe easier it is likely to improve their quality of life.”
During airway bypass, physicians will use a flexible bronchoscope to go through the mouth into the airways. There the physician will create new small pathways and place an Exhale® Drug-Eluting Stent – manufactured by Broncus Technologies, Inc. - to allow the trapped air in the lung to escape. Patients could see an immediate improvement in dyspnea (shortness of breath).
“The airway bypass procedure could be an excellent option for those who may be considering lung transplant or who may not be suitable candidates for lung transplant surgery, which is one of the only other treatment options available for patients with this type of emphysema,” states Todd Horiuchi, MD and sub-investigator of the study at Sarasota Memorial Hospital.
Physicians commonly use bronchoscopes to examine the airways within the lungs. During the airway bypass procedure physicians will first use a Doppler probe inserted through the bronchoscope to identify a site in the airway that is away from blood vessels. A special needle is then used to make a small opening and an Exhale® Drug-Eluting Stent is placed in the passageway to keep it open. The procedure involves placing up to six drug-eluting stents. The total time of the procedure is approximately one to two hours.
This procedure is still under clinical investigation, but early data suggest it may hold promise for patients with emphysema.
Emphysema affects an estimated 60 million people worldwide with more than 3 million sufferers in the United States. There is no cure for emphysema.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
