One of the worst criticisms of #masks is a false binary presented by experts - that alone, widespread mask use is unlikely to be a powerful intervention. But who is saying we need to decouple this from #TestTraceIsolate? Feels like a strawman. Also: #COVID19Aus
The fact that improper mask use is common is surely not enough to dismiss them as a strategy. Surely education about PPE is on the table.
BTW I'm not saying that implementing masks today in Aus would be effective. That's a separate issue. Although, I'm sure even mask skeptics...
are glad that #BlackLivesMatterAustralia protesters used masks so widely. If we could turn the clock back, would we want to run the experiment without them using masks? Is there truly equipoise here?

There is a worldwide shortage of IV contrast, and it's happening in Australia too. What is 'contrast', why is it important, and why is this happening? 🧵
Contrast is a dye that is sometimes injected into patients during investigations such as CT/MRI/Angiograms... wherever the dye is carried by blood vessels, it 'lights up' in the image of the scan.

Sometimes it's nice to have a scan with contrast.
Other times it's critical.
In Victoria, there is a 'critical state-wide shortage' being cited by at least one hospital I'm aware of, forcing it to delay scans or perform other investigations as a substitute.

Last night, I did what I thought'd be a small call out, asking:

"Is every emergency department in Metro Melbourne fucked right now, or is it just some of them?"

I've been hit with an avalanche of messages.

Here is the problem, some causes and solutions, in plain words🧵:
> All the emergency departments (EDs), not some, are fucked, and have been for a few weeks

> It's not just metro Melbourne, but regional EDs too

> It's not just Vic, some other states too

How fucked?
> Ambulances are 'ramped' for hours and hours (waiting in queue to get into the emergency department).

I've Heard of one case of a patient waiting in queue while intubated - breathing tubes down their throat. This is not normal or good.

I'm seeing a lot of people say that Will Smith couldn't have done much damage with his 'slap'. Here's why that's not quite true.🧵 (1/15, for real)
Dying from a strike isn't somehow impossible if it is an open handed strike vs a punch. There are other factors that arguably matter much more.
For starters, conventional wisdom in street fights (where you don't have gloves to protect hands) is indeed to 'slap'

Favouring open handed strikes (esp with heel of hand) instead of a closed fist allows trained fighters to *swing harder* without risking metacarpal fractures.

“Careful it’s spicy”
‘Haha Yeah all good I asked for it spicy”
“No it’s really spicy, a few times while cooking I was coughing, I couldn’t take it”

When the Thai cook of the Thai restaurant tells you it’s too hot for him to breathe, you know you’re fucked.
Will report back in 20
I’m fucken scared tbh
I’ve got a 1 kg tub of yoghurt in the fridge though which should buy me a few moments tweet some final words

I can't wait to hear the non-explanation for the 24 hour Tokyo-drift hairpin u-turn reversal of the isolation+ day 6 RAT policy.

It's not that either decision is right or wrong, it's that the decisions are poorly made and communicated.
A shorter 7 day isolation period has tradeoffs that plausibly will confer a net positive benefit, at a population level.
Day 6 RAT for covid +ves: tradeoffs either way - neg result might let infectious people go early. Infectious people who test positive may be kept isolated appropriately. non-infectious who test positive would be unnecessarily isolated. Trade offs either way.

The world has 2 new COVID pills. But there's an issue.

After symptom onset, you must get tested, get result back, see Dr, start meds, all in 5 days.

If you're likely to follow that process, you're prob also the kind of person who's had access + inclination to get vaccinated🧵
Authorities could recommend the pills to people who're already vaccainted, but the vaccines are already great! That's not the population with most to gain from treatments.

Plus, in 2022, it could be hard to convince fully vax/booster folk with a sniffle to go thru above process
So who are these pills likely to help the most? The unvaccinated.

But are adults who are currently unvaccinated (for whatever reason) in Aus likely to follow through with the process of testing/waiting for results/getting medication I've mentioned above?
