Same. My use case is ultrasound segmentation. These models struggle, understandably so, with medical imaging.

This tracks with my own bias as an ER doc. I do feel that the risk of c-spine injuries from mountain biking is understated. As they said in the article, you are especially vulnerable to a hangmans fracture when thrown over the handlebars. I wonder if the ergonomics or geometry of a bicycle could be modified to better protect a rider’s neck.

You can do CPR without a computer system, but changing systems in the middle of resuscitation where a delay of seconds can mean the difference between survival and death is absolutely not ideal. CPR in the hospital is a coordinated team response and if one person can’t do their job without a computer then the whole thing breaks down.

I sent them your contact info, pretty sure they will be asleep for the next few hours

The system crashed while my coworker was running a code (aka doing CPR) in the ER last night. Healthcare IT is so bad at baseline that we are somewhat prepared for an outage while resuscitating a critical patient.

I would use this at work in the hospital, especially ultrasound guided procedures.

CPR shouldn’t work on someone dead from a traumatic injury. For example chest compressions will only hurt someone dead from having their chest crushed against a steering wheel in a car accident. What happened to you is a true miracle and far outside the norm.

I’ve always wanted to have an MRI. I want to know how it feels to have all of my protons reoriented by a giant magnet. Would I be the same person after?

I use windows when I work in the emergency department. These ads drive me bonkers when I’m trying to use the software to take care of patients.

I presume this is intended for wounds in areas with poor circulation, like a diabetic foot or a walled off abscess. The bloodstream is damn good at delivering antibiotics and immune cells to infected areas.

Received mine this week for a service address on the Navajo Nation. I imagine the wait is shorter for less populated rural areas, which should correlate with need. My old isp charged $60 a month for 1.5 Mb/s down and 750kb/s up. This should be a great improvement.

New comment by davycro in "UK reports 25 fresh cases of thrombosis associated with the AstraZeneca vaccine"

davycro — Fri, 02 Apr 2021 03:30:59 +0000

No seriously. The estimated prevalence of venous thrombosis in the United States is 1:1000. The reported numbers of VTE after the vaccine would be normal in the general population. I am an emergency physician and I diagnose and manage PE and DVT several times per week. To me this seems much ado about nothing.

Those numbers appear lower than the baseline prevalence of venous thrombosis in the general population [1]. Maybe the vaccine is protective?

It would be better if the author had vetted this with an epidemiologist or infectious disease specialist. I am an MD and I feel that this topic is outside my expertise and that I’m not qualified to comment on it. That said the author makes it clear his views are opinion and conjecture. He poses smart thoughtful questions I hadn’t considered and will discuss with colleagues in the future.

Neat suggestion. I too am seeing shades of brown for most queries. Maybe this would help.

davycro — Wed, 13 Jan 2021 15:07:43 +0000

The test in the article screens for colon cancer, which is one of many reasons to have a colonoscopy. It sounds like the GI doctors you consulted performed colonoscopies to assess the cause of your digestive symptoms by looking at your GI tract. The test in the article could not replace that.

davycro — Sun, 10 Jan 2021 21:12:08 +0000

Implantable defibrillators are designed to be stopped by a magnet. This is a critical safety mechanism to stop a defibrillator that continues to fire inappropriate shocks. Any emergency department will have a special magnet just for this purpose. If anything it’s kinda cool that the iPhone can achieve this.

Do you have a citation for this claim? I heard or read similar but then couldn’t find the source.
