Digital Health: Wearable Sensor Data Can Predict Heart Failure 6 Days Before Hospitalization

From a “Circulation: Heart Failure” Journal study (Feb 25, 2020):

Circulation Heart Failure logoThe study shows that wearable sensors coupled with machine learning analytics have predictive accuracy comparable to implanted devices.

We demonstrate that machine learning analytics using data from a wearable sensor can accurately predict hospitalization for heart failure exacerbation…at a median time of 6.5 days before the admission.

Heart failure (HF) is a major public health problem affecting >23 million patients worldwide. Hospitalization costs for HF represent 80% of costs attributed to HF care. Thus, accurate and timely detection of worsening HF could allow for interventions aimed at reducing the risk of HF admission.

Data collected by the sensor are streamed to a phone and then encrypted and uploaded to a cloud analytics platform.

Several such approaches have been tested. Tracking of daily weight, as recommended by current HF guidelines, did not lead to reduction of the risk of HF hospitalization, most likely because the weight gain is a contemporaneous or lagging indicator rather than a leading event. Interventions based on intrathoracic impedance monitoring also did not result in reduction of readmission risk. The results suggest that physiological parameters other than weight or intrathoracic impedance in isolation may be needed to detect HF decompensation in a timely manner. In fact, 28% reduction of rehospitalization rates has been shown with interventions based on pulmonary artery hemodynamic monitoring. More recently, in the MultiSENSE study (Multisensor Chronic Evaluation in Ambulatory HF Patients), an algorithm based on physiological data from sensors in the implantable cardiac resynchronization therapy defibrillators, was shown to have 70% sensitivity in predicting the risk of HF hospitalization or outpatient visit with intravenous therapies for worsening of HF.

Future Of Housing: Kajstaden Tall Timber Building In Sweden By C.F. Møller Architects (2019)

Kajstaden Tall Timber Building C.F. Møller Architects 2019The Tall Timber Building residence has become a landmark and, during construction, became Sweden’s tallest solid wooden building in the new district of Kajstaden at Lake Mälaren in Västerås. All parts of the building consist of cross-laminated wood, which includes the walls, joists and balconies as well as the lift and stairwell shafts.

Kajstaden – Tall Timber Building is an important landmark for sustainable construction and a reference project that shows that conversion to climate conscious architecture is possible. Through research projects and several active wood projects, C.F. Møller Architects has focused on innovation as well as developing and implementing multi-storey buildings with solid wood frames. In Kajstaden, an active decision was made to prioritise industrial timber techniques for the building material to influence and take responsibility for the impact of the construction industry on the environment and climate change. A crucial advantage of wood, unlike other building materials, is that the production chain for the material produces a limited amount of carbon dioxide emissions. Instead, it is part of a closed cycle, where carbon is retained in the frame of the building.

Truck Tech: “2020 Nikola Badger” Electric Pickup Will Have 600 Mile Range

Nikola Badger LogoThe Badger was designed to handle 0-100 mph launches with minimal loss of performance and to operate on grades up to 40% through advanced software blending of batteries and fuel-cell. With a fully loaded trailer and combined vehicle weight of 18,000 lbs., the Badger will be able to launch from a standstill on a 30% grade without motor stall.

PHOENIX, AZ (February 10, 2020) — Nikola Corporation is excited to announce the product launch of the Nikola Badger electric pickup truck with an estimated range of 600 miles.

Unlike anything on the market, the advanced electric pickup is designed to target and exceed every electric or petrol pickup in its class. The Badger is engineered to deliver 980 ft. lbs. of torque, 906 peak HP and 455 continuous HP. The Badger will be built in conjunction with another OEM utilizing their certified parts and manufacturing facilities.

The electric pickup is designed to handle what a construction company could throw at it and is engineered to outperform all electric pickup trucks on the market in both continuous towing, HP and range. The Badger will be outfitted with a 15-kilowatt power outlet for tools, lights and compressors, which is enough power to assist a construction site for approximately 12 hours without a generator.

“Nikola has billions worth of technology in our semi-truck program, so why not build it into a pickup truck?” said Trevor Milton, CEO, Nikola Corporation. “I have been working on this pickup program for years and believe the market is now ready for something that can handle a full day’s worth of work without running out of energy. This electric truck can be used for work, weekend getaways, towing, off-roading or to hit the ski slopes without performance loss. No other electric pickup can operate in these temperatures and conditions.”

Heavy D, a reality TV star from the “Diesel Brothers,” has partnered with Nikola to design, build and test the Badger in real world environments, which is anticipated to attract millions of viewers and followers through the process. The partnership will follow the Badger build from concept through production.

“My audience, hard-core truck enthusiasts, has expected me to push the limits of truck power and capabilities since my beginnings,” said Heavy D, AKA Dave Sparks. “Being able to pull back the curtain of a production truck build is a rare opportunity where we can include the everyday truck owner to participate in the final outcome of design, exterior choices and performance specs. I wanted to be part of that story and now I have the opportunity with Nikola.”

“The Nikola Badger is a game changer. The program will help drive down the cost of the fuel-cell components on our semi-truck while accelerating the hydrogen station rollout. Giving customers the option to order a fuel-cell or battery electric version will ensure we drive the cost down for everyone across our lineup,” said Mark Russell, president of Nikola Corporation.

The Nikola Badger will make its first appearance at Nikola World 2020 in Phoenix. Prototypes will be available for select customers and media to ride in at Nikola World.
