Wearables: heart rate measurements vary by activity

18.02.2020

Biomedical engineers at Duke University have demonstrated that while different wearable technologies, like smart watches and fitness trackers, can accurately measure heart rate across a variety of skin tones, the accuracy between devices begins to vary wildly when they measure heart rate during different types of everyday activities.

TAVR shows similar safety outcomes as open-heart surgery

07.02.2020

A new study from the Smidt Heart Institute at Cedars-Sinai and other centers nationwide shows that patients who underwent a minimally invasive transcatheter aortic-valve replacement (TAVR), had similar key 5-year clinical outcomes of death and stroke as patients who had traditional open-heart surgery to replace the valve.

Multicentric study identifies new biomarker for vascular dementia

06.02.2020

Vascular dementia is caused by a defect on blood flow arrival to the brain, which consequently generates neuronal damage. Since now, its diagnosis has been quite complicated because only neuroimaging methods and the appearance of symptoms were available.

New stretchable battery can power wearable electronics

28.01.2020

Electronics are showing up everywhere: on our laps, in pockets and purses and, increasingly, snuggled up against our skin or sewed into our clothing. But the adoption of wearable electronics has so far been limited by their need to derive power from bulky, rigid batteries that reduce comfort and may present safety hazards due to chemical leakage or combustion.

Wearable AC monitors vital data

07.01.2020

One day, soldiers could cool down on the military battlefield – preventing heat stroke or exhaustion – by using "wearable air conditioning," an on-skin device designed by engineers at the University of Missouri. The device includes numerous human health care applications such as the ability to monitor blood pressure, electrical activity of the heart and the level of skin hydration.

Imaging shows possible cause of noise-related blood vessel damage

05.12.2019

Each 5 decibel increase in environmental noise is associated with a 34% increase in risk for a heart attack, stroke, or other cardiovascular disease event.

'Smart' surfaces help to improve blood-vessel grafts

03.12.2019

Researchers at McMaster University have created a new coating to prevent clotting and infection in synthetic vascular grafts, while also accelerating the body's own process for integrating the grafted vessels.

MEDICA TECH FORUM: light-based imaging technique OCT

04.11.2019

Since its inception, MEDICA TECH FORUM has focused on the implementation of innovations and new technologies into clinical practice. 2019 marks the tenth year of the Forum. In honor of its anniversary, we will brighten things up a bit, as one of the focal points will highlight how optical coherence tomography (OCT) uses light to produce images.

Sports medicine – keep moving to stay healthy

01.07.2019

Physical activity plays a big role in today's society. Whether you are an amateur or professional athlete – incorporating exercise into your life positively impacts your mental and physical health. Ideally, sport should be fun, pressure-free and not overburden you. But can you measure individual performance and align it with sports?

Cardiac arrhythmia: treatment in the linear accelerator

08.04.2019

Cardiac arrhythmia is a group of conditions where nerve cells trigger uncontrolled contractions of the heart muscle. They are treated with either medicine or catheter ablation of the tissue. In an interdisciplinary collaboration, cardiologists and radiotherapists took a different approach and used high-precision radiation therapy to treat a patient for whom the other options proved unfeasible.

WAKE-UP study a wake-up call for acute stroke care

08.08.2018

Some solutions are simple, though not necessarily obvious. The WAKE-UP study, which included 70 participating European stroke centers, has now studied a relatively simple procedure to manage the acute care of stroke patients and avoid potential long-term effects. Best of all, it is available wherever MRI is offered.

Ventricular fibrillation – Using ultrasound to detect its causes

17.05.2018

Ventricular fibrillation is a life-threatening condition that occurs when the heart muscle exhibits a rapid, erratic beat. The cause might be a circulatory system disease or heart attack. Researchers in Göttingen are now developing an ultrasound technique to get to the bottom of ventricular fibrillation and cardiac arrhythmias and facilitate better treatment options.

Tissue engineering: how to grow a bypass

23.04.2018

A bypass is a complicated structure. It is either made of synthetic materials that can cause blood clots and infections or created by using the patient’s veins. However, the latter often does not yield adequate material. A newly developed bioreactor could solve this problem in the future. It is designed to tissue engineer vascular grafts by using the body’s own material.

Between austerity measures and growth pressure - Latin America's medical market

03.04.2018

A region whose states make up the world's third largest economy and which has few linguistic differences - Latin America is an attractive market for foreign companies at first glance. This also applies to the medical market. However, various factors are contributing to the fact that this market is growing only slowly in most countries.

"Spray-On" muscle fibers for biomimetic surfaces

08.01.2018

Few patients with heart failure are fortunate enough to receive a donor's heart. Ventricular assist devices (or heart pumps) have been around for several years and are designed to buy time as patients wait for a transplant. Unfortunately, the body doesn't always tolerate these devices.

ICAROS VR - Training and Prevention in Virtual Reality

31.08.2017

The term gamification refers to the application of elements of game playing in non-game contexts, for example, to encourage participants to engage in a task that is otherwise deemed too monotonous. We are visiting the German Sport University Cologne to interview Dr. Boris Feodoroff, who together with his team is testing a training device.
