If you have complete AV block, a leadless pacemaker is less good than one with multiple leads, since it allows pacing multiple chambers and maintaining synchrony between A and V.
It’s a research dataset, similar to MNIST or CIFAR. Stanford does not want to be in the business of monetizing patient data, so it restricts commercial use.
With AIMI, we released EchoNet-Dynamic, the largest open dataset of echocardiograms (cardiac ultrasounds) and expert cardiologist labels as part of a paper published last year. The dataset went through a rigorous review to make sure no identifying information was leaked as part of the process. Happy to answer any questions.
I have absolutely nothing against CGMs, but the author confounds measurement error (which can happen in both blood tests as well as subcutaneous measurement which a CGM does), thresholding on a population level (I doubt anyone thinks an A1c of 4.5 and 5.6 are the same), and weak evidence of impact in actual health outcomes. It’s fun in the same way a Fitbit/Apple Watch is fun, but I don’t think one should oversell it’s utility.
I think number of launches was used as a proxy for number of satellites launched in the last month - more satellites/launch shouldn't impact it that much.
I'm going to be a cardiology fellow at Stanford in July, we use ultrasound often for both bedside informal exams as well as diagnostic echocardiogram. I've used handheld devices like the Lumify and Vscan, as well as the large tractor sized epiq machines. Similar to what is written in the article, my impression is that the actual hardware, specifically the transducer, is quite expensive to manufacture. The software and processing power continues to get cheaper but to have to best quality pictures, require expensive transducers. I've actually been very very impressed by the Lumify and I think it is getting near if not better than the quality of the gigantic epiq machines, primarily by having a very high quality transducer. This is indeed a hot area and knowing people who are actively doing development in the field, there are poeple trying things like having a giant paralleled transducers over the entire chest for continuous 3D images and other interesting ideas that are limited more by hardware than processsing power or imagination.
