Hafnium nanoparticles that home onto microfractures in bone make the tiny cracks visible in spectral or color computed tomography (CT) imaging. Researchers at the University of Illinois at Urbana-Champaign and the University of Maryland created the nanotechnology to work in conjunction with spectral molecular imaging developed by New Zealand-based MARS Bioimaging Ltd. (MBI). The research appeared in Advanced Functional Materials.
The case of Arthrex v. Smith & Nephew, Inc., has raised a host of questions about the appointment of judges to the Patent Trial and Appeal Board (PTAB), and witnesses at a congressional hearing said a Supreme Court review might be two years in coming. Any such resolution might not clear out the thicket of underlying legal questions, however, and thus the witnesses urged Congress to take action quickly even as the Federal Circuit considers an en banc hearing of the matter.
A team led by researchers at Washington State University (WSU) has developed a nanoparticle technology to deliver cell-killing drugs to shut down the overactive immune response that can cause damage or death in diseases like stroke and sepsis without affecting other cell types or compromising the immune system.
There are a pair of approved CAR T drugs, Yescarta (axicabtagene ciloleucel) from Gilead Sciences Inc. and Kymriah (tisagenlecleucel) from Novartis AG, that have been available since 2017 for a few hematological cancers including some lymphomas and leukemias. But little is known about how these engineered chimeric antigen receptor T cells that both target CD19, an antigen prevalent in the cells of many B-cell malignancies, move through the body and proliferate after they are first removed, altered, expanded in number and, finally, returned to a patient's body.
Hand-held diagnostics don't come cheaply, and their applications remain somewhat limited. Abbott Laboratories' Istat portable clinical analyzer, for example, retails at about $15,000, with each individual cartridge costing hundreds of dollars apiece to measure each of roughly a few dozen blood gas, electrolyte, chemistry and hematology levels in few minutes from two to three drops of whole blood.
A neuropsychologist consult is typically the first step for a neurologist in aiding in the diagnosis and monitoring of neurological conditions. But timely appointments for an assessment by these specialists can be difficult to obtain, even under the best of circumstances. To better enable neurologists to assess which patients are most in need of a consultation with a neuropsychologist, Royal Philips NV has launched an artificial intelligence (AI)-based cognitive assessment tool in the U.S. Known as Philips Intellispace Cognition, the digital, cloud-based assessment tool takes established neuropsychological tests and enables their administration by a medical assistant via a tablet in an office setting.
Patients undergoing transcatheter aortic valve implant may need a pacemaker after the TAVR device, but a new study suggests that right bundle branch block may predict the need for pacing. The data may have implications for device selection as some devices are seen as less likely to trigger the need for a pacemaker, a development that may move the needle in the robust but increasingly competitive market for TAVR.
Virta Health Corp. reported 90-day data from a pilot study of its Virta Treatment for type 2 diabetes (T2D) in military veterans. Conducted jointly by Virta and the U.S. Department of Veterans Affairs (VA), the pilot shows 84% of participants who used the low carbohydrate and diabetes coaching model reduced their glycemic levels to below the diabetes threshold or experienced at least a one-point drop in HbA1c, a measure of blood sugar.
The Alfred Mann Foundation (AMF) and Össur have signed an agreement that will allow Reykjavik, Iceland-based Össur to further develop and license the implanted myoelectric sensor (IMES) system developed by AMF. Both organizations expect clinical trials to begin within the year.
Diabetes management company Dexcom Inc. trounced Wall Street forecasts for the third quarter of 2019, with the company reporting worldwide sales of $396.3 million, up 49% from $266.7 million in the same period of 2018. Dexcom officials attributed the surge to volume growth plus new patient additions as providers and consumers become more aware of the benefits of real-time continuous glucose monitoring (CGM), where Dexcom's G6 has seen steady demand since launching in June 2018.
