A thread based on Figure 1

UAMS has taken the extraordinary step of asking leadership across our health system to refrain from traveling over the coming holidays and report to work or be available if needed. Other hospitals in our state are considering similar measures.

(1)

Although the health care system in the state of Arkansas is stressed right now, it is holding up, and additional surge capacity exists. But that capacity is not infinite.  Every day, we become more and more concerned about our ability to manage what lies ahead.

(2)

As health professionals, we are doing all we can. However, one thing is certain. We can’t meet this challenge unless you are with us. As Secretary Jose Romero of the AR Dept. of Health has said, we are in the midst of a “surge within a surge” in this COVID-19 pandemic.

Right now, the @UAMS_COPH COVID-19 forecasts, which have been strikingly accurate so far, indicate that the density of COVID-19 infections exceeds each of our abilities—yours & mine -- to avoid contact with actively infected individuals in our state...

...whenever we venture outside our homes. They predict an exponential increase in coronavirus deaths in the next two weeks, more than we saw in the first four months of the pandemic. We may soon exceed the number of beds, ventilators, & most importantly...

Masks. A short thread. In June last year my GP advised me that wearing a mask even for a short space of time would be harmful for me on two fronts. One - I have painful rosacea on my face. It’s a horrible condition and it’s lifelong. I can at times look scary!

Putting on a mask simply makes it worse. Two - I have hypertension. Manageable and controlled. GP also advises that mask wearing even for short periods can raise cortisol levels and make them dangerous to me.

On that basis and given the dreadful treatment us non-maskers have to suffer and to appease the abusers I have three times asked my GP to issue me with a letter relating to my conditions.

On each occasion she has said that there is no need. Whilst she won’t admit it straight up, all conversations suggest she’s been told not to. I happen to agree that no-one should need to reveal their medical history to anyone other than medical professionals responsible for me.

I’ve researched mask wearing in relation to what they are supposed to be used for ref *Covid* - I’m no thicko - I prepare risk assessments (and I’m qualified to do so) every day (or did) - and the evidence *for* is weak. Very weak.

half of this website believes that all of your problems can be solved by going to therapy

another half thinks that the entire psychological profession is fake and after some vaguely construed revolution mental health will be solved

what's funny about this is that nothing about it new

I wish this wasn't paywalled because the books Lasch reviewed (in 1976!) sound very familiar. The same kind of dumb debates on this subject that occur constantly here are inherited from boomers

the point Lasch makes towards the end is that all of these books are grasping towards something that neither therapy or politics fully covers, even if both are obviously relevant.

but first, he does a tour through the books. he encounters people who believe all character traits are a product of "propaganda" and "conditioning" that can be fixed with therapy or therapy-like processes, and people who think therapy is a distraction from politics

2 / But for these to be effective and to guarantee protection against CCR, they must meet a series of conditions. One of them is the correct indication for endoscopic studies for both screening and surveillance.

3 / According to a recent meta-analysis, the minority of patients who undergo colonoscopies have a correct indication, with less than 50% adherence to the surveillance intervals proposed by scientific
