Artificial Intelligence healthcare developer Viz.ai said this week it won approval from the FDA for its LVO Stroke platform designed to analyze computed tomography results and notify providers of potential strokes, touting it as the first such system to win FDA clearance. The company’s LVO Stroke platform is designed using deep learning and connects to a hospital CT scanner to alert stroke specialists that a suspected LVO stroke has been identified, with the ability to send radiological images directly to the physician’s phones. “Timely LVO stroke identification and transfer to a specialist hospital that ...

If many stem cell therapies produce their benefits largely through the signaling generated by the transplanted cells, in a brief window of time before these cells die, unable to integrate into the local tissue, then why not skip the cells entirely and just deliver the signals? This is made an easier prospect by the fact that a great deal of cell to cell signaling takes the form of extracellular vesicles such as exosomes, tiny membrane-bound packages of various molecules. Thus researchers don't need to completely map and understand the entire set of signals used in order to recreate most of the signaling effects of stem cel...

(CHICAGO) — The first blood test to help doctors diagnose traumatic brain injuries has won U.S. government approval. The move means Banyan Biomarkers can commercialize its test, giving the company an early lead in the biotech industry’s race to find a way to diagnose concussions. The test doesn’t detect concussions and the approval won’t immediately change how patients with suspected concussions or other brain trauma are treated. But Wednesday’s green light by the Food and Drug Administration “is a big deal because then it opens the door and accelerates technology,” said Michael Mc...

BackgroundThe major factor for the appropriate treatment strategies for ischemia patients is its onset timing. Purpose/HypothesisTo study to evaluate the diagnostic accuracy of T1 relaxation time in a rotating frame (T1ρ) and apparent diffusion coefficient (ADC) from MRI to estimate ischemia stages. Study TypeProspective. Population/Subjects/Phantom/Specimen/Animal ModelIn all, 73 patients (49 males, aged 29–78 years and 24 females, aged 22–94 years) with ischemia were prospectively imaged with T1ρ and diffusion MRI during the postischemic period. Field Strength/Sequence3T/T1ρ and diffusion‐weight...

Abstract PURPOSE: Infarct core can expand rapidly in acute stroke patients receiving intravenous tissue plasminogen activator (IV t-PA). We investigated changes in the extent of infarct core during IV t-PA treatment, and explored the associative factors of this infarct core expansion in patients with proximal artery occlusion. MATERIALS AND METHODS: We included patients who were considered for sequential intra-arterial therapy (IAT) due to occlusion of intracranial proximal artery after IV t-PA. Patients who had a baseline Alberta Stroke Program Early Computed Tomography (CT) Score (ASPECTS) ≥6 and who und...

It has never been easier to measure ECG and monitor heart health at home. New pocket-sized gadgets, chest straps, even specialized earbuds promise accurate measurements during sports activity, cooking or watching TV at home. AliveCor’s Kardia, MocaCare, Skeeper, just to name a few digital devices The Medical Futurist already reviewed. Recently, a Swedish company sent me their version and I eagerly tested it. Let’s see what the Coala Heart Monitor can offer. The ECG Revolution A real revolution started in cardiology: miniaturized and patient-friendly designs of ECG monitors, single- and multi-channel ECGs arrive...

Background and purposeTime sensitivity for pharmacological and mechanical arterial recanalization in acute ischemic stroke influences the choice of the reference hospital. The accurate selection and identification of patients with high probability of a large vessel occlusion (LVO) in the prehospital setting improve the rationalization of the transport in the more suitable centers. Aim of this analysis was to determine the diagnostic accuracy of prehospital stroke scales detecting LVO. Material and methodsStudies were searched into MEDLINE, EMBASE, and CINHAL databases between January 1990 and September 2017. Principal meas...
