For circumstances like this I create a VM with a version of MacOS that the app works with, and keep it on life support that way (doing this at the moment for Finale, music notation software that works well with Piano Marvel and thus gamifies piano practice for my kids…)

Similar program in Melbourne [1] https://sjtrem.biomedcentral.com/articles/10.1186/s13049-023...

(There are similar programs around the world with different models of care, notably in Paris, Albuquerque, the Netherlands and Regensburg, Germany).

A counterpoint on focused ultrasound for essential tremor - just because you don’t penetrate the brain with a physical object doesn’t mean you don’t have side effects - as usual, benefits come with risks

I own the 1st gen of the Butterfly - in my opinion, it wasn't great image-wise compared with the contemporary conventional crystal based probes (thinking of cart-based machines with less flexible, more expensive probes etc so perhaps an unfair comparison). Would be cool if the newest ones mentioned in the article are becoming comparable with the crystal based probes - I can't comment. But I can say image quality is absolutely key. There are lots of cool AI based applications coming out all the time (I know much more about echocardiography AI than the foetal ultrasound AI mentioned in the article, but this is a similar paper where some ultrasound novices had AI guidance and were able to obtain useful echo images https://www.ahajournals.org/doi/10.1161/CIRCIMAGING.123.0155...). I get to use various machine vision based tools on echo images at work to automate various measurements - but at the moment, I find they fail badly if the imaging is anything but great quality, whereas humans can interpret them. Maybe future training sets will include more "technically difficult studies" (code for poor imaging) and AI tools will do better than they do now? Or there will be more augmentation of data sets with realistically degraded versions of images to add robustness? AI that worked on suboptimal images would be awesome, particularly in my setting (ICU).

Not quite the same but when we were rebuilding during COVID we knew we wanted two good WFH spaces but really only had room for one (tiny) office - as our second we built a shelf in our bedroom wardrobe that lifts up to reveal a work surface and a 32" monitor - inspired by this guy's work on ikeahackers:

https://ikeahackers.net/2020/10/fold-out-desk-home-office-pa...

Works really well and given the cost of space for a second desk it was a very cost effective solution - only minimally affects the utility of the wardrobe as a wardrobe. (We didn't build the laptop holder this guy describes, the laptop just gets sat on top of the clothes in the drawer below that shelf with attention to make sure we're not blocking a fan intake. We had a powerpoint and a ethernet port put into the back of the wardrobe but actually we just end up using Wi-Fi mostly.)

I'm a doctor (ICU) who also does some IT stuff for work (nothing complex, mainly writing small web apps). I really enjoy writing stuff where you know the requirements, make all the decisions, write the code and maintain it. However, doing this has allowed me to get some exposure to what bigger projects with lots of moving parts, data sources, stakeholders, regulatory requirements etc look like - and it's seriously hard work. Nothing like "coding, the hobby".

I guess this commonly occurs in many fields at a certain level of seniority - the "managing a large system involving many people" aspect can dominate the domain-specific part, be it software engineering, accounting, manufacturing etc. As such I'm really glad I chose medicine rather than SWE (even though I've been writing and loving code for >35 years, and it was a real toss-up when I went to uni) because:

1. You can still stay very hands on, even as a senior clinician, especially procedurally.

2. If you so choose, there's a lot of variety in what you find yourself doing as a doctor (my mix looks like making clinical decisions / talking to patients / families / doing procedures / performing and interpreting ultrasound / going to other hospitals to retrieve super sick patients and bringing them back in ambulances / mentoring / teaching / coding / managing a clinical service / etc - but there are lots of other options too). I'm not sure if this kind of variety is as easy to arrange as a SWE? (though I suspect I'm about to be corrected, thanks in advance.) Variety is quite important if you're easily bored, which is a common problem for bright people.

3. Although AI is coming to all fields, I do think the impact will look more like "better tools", rather than "job replacement", or "vast reduction in number of people needed", for longer in medicine (at least in my area). As a breadwinner this is a not inconsequential consideration.

Hope you find the career you love, and that it leverages the work and study you've already done in some way.

A 27 or 30G insulin needle with some lidocaine (still often called lignocaine here in Australia ) is a nice addition to this procedure. I rarely omit it unless the patient is unconscious. If you inject the local anaesthetic under real time ultrasound, it can also serve as a seeker so you see if you’re off target with the 30G needle and adjust based on that information, which improves your success with the larger (commonly 22G) needle used to take the gas. Not unreasonable to request local anaesthetic, really - it is known to be a painful procedure.

For really small kids we tend to use a transilluminator rather than ultrasound for peripheral IVs (though it doesn’t tell you the depth like ultrasound does). For CVCs or bigger people, ultrasound is often very useful. Like all things, experience makes a big difference! In my opinion, for known tricky veins (in adults at least) it’s best to use local anaesthetic from the outset - it does make it slightly harder but if (when?) you miss it’s easier to keep the patient on side for the next attempt.

Edit: YouTube link to a transilluminator being used - beware the video does have an unhappy child in it

I also wonder how much it might heat up the brain? And whether that would be a problem for sustained use? (In practice this heating effect is occasionally limiting for some other forms of ultrasound (e.g. TEE) requiring you to take a break or reduce the power.)

In my experience the commonest current mainstream use of this is for Sezary Syndrome / mycosis fungoides (cutaneous T-cell lymphoma). See for example:

As others have commented above, reducing the rate of spread (social distancing and hygiene, and convincing others to do likewise) so that this is a more smeared out event with a lower peak need for equipment and staff is the most important intervention. It's also very hard to do; not sure if there is a technological lever that will move the needle on this (advertising?)

Agree. I'd add that my comment above about exhalation being passive is true in adult ICU practice. In high frequency oscillatory ventilation (HFOV) exhalation is active (a piston actively creates a negative pressure in the breathing circuit). I understand this is still used quite a bit in neonates (though I don't do NICU, so not an expert) but has gone out of favour in adults in a big way due to the results of trials like OSCILLATE (https://www.nejm.org/doi/full/10.1056/NEJMoa1215554). Probably still used in some centres as a rescue therapy, but I haven't used it in years (we'd use VV ECMO for that purpose).

Actually exhalation is passive, not active, in modern day ICU ventilation.

- COVID-19 seems to be mainly hypoxic respiratory failure, not hypercapnic respiratory failure

- NIV (Non invasive ventilation, CPAP is essentially a form of this) doesn't typically perform well (on a patient outcomes, mortality basis) for pneumonia with hypoxia compared with invasive ventilation. However, this is thought to partly be because NIV delays the decision to proceed with intubation and ventilation. If there is no ventilator available, that might change the value of NIV.

- NIV will also likely cause aerosolisation of the virus facilitating spread if there are others in the area. Most sleep apnoea CPAP masks are vented which would probably make this worse (cf unvented masks commonly used on ventilators in an ICU setting)

- Many sleep apnoea CPAP machines don't allow entrainment of supplemental oxygen, which would be likely to be needed in critical COVID-19 infection

I'm sure I'm not their biggest customer, but I have bought in the hundreds of dollars worth of books each year from O'Reilly for the last few, consumed as DRM free PDFs. Definitely going to re-evaluate that. When I want to buy a book on a topic I used to Google "O'Reilly <insert topic here>" as my first port of call. That just ended. I'll look to other publishers first instead, and cease recommending O'Reilly.
