A car manufacturer has recently developed a new medical device designed to alleviate motion sickness, given that approximately 30 million people in Europe alone suffer from chronic travel sickness, and one in three people develop symptoms at least once in their lifetimes.
It is widely known that exercise and physical activity help combat chronic disease, and promote overall health & wellness; yet in the past decade, there has been a proliferation of specific devices and methods to promote more frequent exercise.
Recently emerging innovative technology could dramatically change how millions of people monitor their blood sugar levels: an approach that utilizes artificial intelligence (AI) and radar technology, including high-frequency radio waves to monitor blood sugar levels without the need for finger pricking.
Silver has long been known to fight bacterial infections, and a new antimicrobial wound dressing called Silverlon demonstrates similar benefits.
According to Raul Brizuela, president and CEO of Argentum Medical, it is not the silver itself that is antimicrobial.
The Food and Drug Administration has approved the Zephyr Endobronchial Valve (Zephyr Valve), a device to treat breathing difficulty associated with severe emphysema.
The device operates in a straightforward manner: a doctor places Zephyr Valves, similar in size to pencil erasers, into the diseased areas of the lung airways during a procedure in a hospital setting. Clinicians use a flexible bronchoscope, a device designed to prevent air from entering the damaged parts of the lung, while allowing trapped air and fluids to escape. During inhalation, the valves close, and prevent air from entering the damaged part of the lung; during exhalation, the valves open–letting out trapped air, which is intended to relieve pressure.
“Treatment options are limited for people with emphysema who have severe symptoms that have not improved from taking medicines. These have included lung surgery, such as lung volume reduction or lung transplants, which may not be suitable or appropriate for all patients,” says Tina Kiang, Ph.D., acting director of the Division of Anesthesiology, General Hospital, Respiratory, Infection Control and Dental Devices, in the FDA’s Center for Devices and Radiological Health. “This novel device is a less invasive treatment that expands the options available to patients.”
The FDA cited statistics issued by the Centers for Disease Control and Prevention, which estimate that 3.5 million American adults have been diagnosed with emphysema. Emphysema is a type of chronic obstructive pulmonary disease (COPD) that occurs due to damage in the air sacs (alveoli) in the lungs.
Lung damage from emphysema is irreversible: the damaged alveoli can cause used air to become trapped in the lungs during exhalation. This can ultimately enlarge the diseased parts of the lung, and put pressure on the healthy part of the lung–which makes it difficult to breathe. As a result, the body may not receive necessary oxygen.
Data from a multi-center study of 190 patients with severe emphysema was reviewed by the FDA. In the study, 128 patients were treated with Zephyr Valves and medical management according to current clinical guidelines, including medications (bronchodilators, corticosteroids, antibiotics or anti-inflammatory maintenance medications) and pulmonary rehabilitation. Some 62 patients (the control group) solely received medical management.
According to the FDA, at one year, 47.7 percent of patients treated with Zephyr Valves experienced at least a 15 percent improvement in their pulmonary function scores, compared with 16.8 percent of patients in the control group. Adverse events observed in the study included death, air leak (pneumothorax), pneumonia, worsening of emphysema, coughing up blood, shortness of breath and chest pain.
The Zephyr Valve was granted ‘Breakthrough Device’ designation, meaning the FDA provided intensive interaction and guidance to the company on efficient device development, intended to expedite evidence generation and the agency’s review of the device. According to an FDA spokesperson, “To qualify for such designation, a device must provide for more effective treatment or diagnosis of a life-threatening or irreversibly debilitating disease or condition, and meet one of the following criteria: the device must represent a breakthrough technology; there must be no approved or cleared alternatives; the device must offer significant advantages over existing approved or cleared alternatives; or the availability of the device is in the best interest of patients.” The FDA granted approval of the Zephyr Valve device to Pulmonx Inc.
A team of researchers at the University of Illinois have come up with a microscope system that can image living tissue in real time and in molecular detail, without any chemicals or dyes. The new technology could boost cancer study.
Foodborne illnesses affect 48 million Americans each year, a grim statistic that leads to over 128,000 hospitalizations and 3,000 deaths, according to the U.S. Centers for Disease Control and Prevention.
Yet recent findings published June 27 in the journal Nano Letters indicate that technology can be employed to prevent consumers from buying and/or eating tainted food.
A study published in the journal Autism Research provides hope that virtual reality can buttress social skills of autistic students.
Stents have become common in treating heart problems. The problem: one in three individuals who have had a stent implanted to keep clogged arteries open and prevent a heart attack will experience restenosis.
