Study out of southern switzerland. Measures of depression, anxiety, and stress varied as the pandemic went on, but overall numbers not particuarly high compared to other reported numbers. they did increase, however.

Interesting conclusion:

"anxiety and stress almost doubled over ten months following the end of the first pandemic wave. However... psychological distress may not be worse compared with pre-pandemic, and may in fact be less marked than in neighbouring countries in Europe."

super important, people who had chronic diseases far more impacted than those without.

Reviewing a PUBLISHED PEER REVIEWED paper about anxiety prevalence during the pandemic in the UK, and the authors commented that because this funnel plot is symmetrical, publication bias is unlikely.

NONE OF THE STUDIES ARE IN THE FUNNEL!!!!!

Funnel plots are supposed to give you confidence that the estimate is not biased. Usually, it's to "show you if there is a bias around the mean."

In this case, the funnel plot serves to tell us to simply throw out the effect size.

As the error gets smaller, the certainty range is supposed to get smaller, that's the entire point of the funnel plot.

This is simply a metaanalysis of randomness.

I really don't miss the hubris of old doctors who love to wax poetic about how great things were before modern ideas took over. It could be about some new technology or theory or idea. But it always goes back to "it was worse than we were before".

I dislike it so much.

First, there are few things in healthcare that were better 100 years ago. Mortality rates were higher, life expectancy of his lower, outcomes were much worse, and treatments much more inhumane.

Second, in almost always centers especially in the West around whiteness and ableism. There may be some who found it better earlier, but I promise you there are many groups who would never go back in time if given the chance.

The Rosette Nebula (Caldwell 49); captured in Hydrogen alpha-Oxygen3-Oxygen3 detail, and full colour stars.

This nebula is 65 light years across and about 5,000 light years away.

Thread: how do I do this?!

/1

I have taken a picture of this before... it was one of my best taken from my DSLR + simple star tracker setup.
However, you can see that the detail with the telescope+guided mount is much sharper.

With hydrogen & oxygen filters, I can separate the data cleanly, too.

Incredibly, the photo is taken from my balcony in Vancouver, where there is a tremendous amount of light pollution, AND it was taken pretty much directly pointing at a 3/4 moon. It was not a DARK sky at all.

Mental health note:

Fear is not unhealthy. It saves you from bears and car crashes and deadly viruses. Reasonable fears respond to distress.

Unreasonable fear is unhealthy. It preoccupies you with unhelpful thoughts that are exaggerated. Unreasonable fears only add distress.

It is unreasonable to fear masking occasionally as a cause of childhood developmental delay.

It is unreasonable (at this point) to fear COVID vaccination due to side effects or inefficacy.

It is unreasonable (with our current data) to fear that measures have caused suicide.

It is unreasonable to fear that masking can cause hypoxia or infection.

It is unreasonable to fear vaccinated people shedding virus or mutating virus.

In this study, we took a look at the types of mental health presentations for kids over a 3y period. We used the HEARTSMAP, a reliable tool for helping emergency departments document psychosocial assessments and help with treatment planning.

In total, we looked at the HEARTSMAP data for 1,530 kids.

Broken down by the HEARTSMAP domains:

PSYCHIATRIC: 40% with severe concerns
SOCIAL: 27% moderate/severe concerns
YOUTH HEALTH: 22% moderate/severe concerns
