1/ A little #astrophotography demonstration.

Astrophotography is allllll about light. The more photons of light you can deliver to your camera, the better.

For example, here is the Orion Nebula:

15 seconds, Nikon D850 @ 600mm ISO 800 The orion nebula at 15 seconds of exposure, with some of the
2/ Here's the same Orion Nebula but with 5x the light!

80 seconds, Nikon D850 @ 600mm ISO 800 By increasing the exposure time, more of the Nebula is seen
3/ And finally, the power of STACKING. By taking multiple pictures, the computer can stack them together to bring out even fainter details.

Nikon D850 @ 600mm ISO 800
22 x 15 seconds
14 x 80 seconds
Stacked together = 24 minutes 10 seconds

I love this hobby :)

/1 Thread: Do better, American Suicide Organizations.
(content warning, obviously!)

If @afspnational incorrectly states "White middle age" as the peak rate of suicide, ignoring the Indigenous youth/young adult suicide crisis, that's a fail. Part of systemic racism.

4 Pics: American Foundation for Sui...Incorrectly states that the...I go to the CDC Wonder data...And 'lo and behold!  The pe...
/2 LOOK AT THIS! AHHHHH! How could a major national organization not put this front and center about statistics?!?!

The rate of 15-19 year old Indigenous males is as high as almost EVERY white age bracket! As described in the text.
/3 For the past 21 years, the highest rate of suicide is Indigenous males, by 7%. The peak rate is between 18-27y at 33.6/100k

For White males, the "middle age peak" between 48-57 is 31.5/100k.

Since I've looked, I've not seen the AFSP mention this in their statistics page. Graph as described in the t...

1/ A Thread with Nuance!! (Japanese suicidology)

Because the media is obsessed with Japanese suicide data ("suicidal" Japan is a lazy, one-sided trope in Western news)...

First, here are the graphs for who suicides in Japan for the past 5 years, to Feb 2021! A graph showing suicides fo...
2/ If we zoom into the men, we can see that there was a decrease in early 2020, an increase at the end, and things are back to normal-ish for 2021. In fact, 2021 is a record low for January and 2nd lowest for February. As described in the tweet.
3/ If we zoom into the women, we can see that there is again an early mild decrease followed by a SUBSTANTIAL increase at the end of 2020. Though things are still elevated in Jan-Feb 2021, much less so and hopefully on the way to normalizing. As described in the tweet.

Pro Tip Thread: "exceptions to the rule"

Being a caring human being should come before "requirements", and though guidelines are largely helpful, one need not slavishly follow them as they can harm.

If exceptions required, document the reasoning.
This is GOOD care.

Content warning: suicidal thinking, depression

CASE (not real) Example:
An adolescent teen, "Javier", who I am seeing in the emergency department for depression.

As I get to know them, I start asking them why they're here, in the ER. What's gotten so bad.

/2
Javier:
"I was sent here by my counsellor because I told her I was having suicidal thinking. I told her because she asked but its not like I was going to do it... I just... sometimes I think about it. Soon as I said it, she ended the session and called my mom to take me to ER.

1/ VERY SERIOUS, VERY COMPLEX DISCUSSION AHEAD:

The @FAIRHealth White Paper showing MH insurance claims in kids is being reported deceptively.

WRONGLY (!!!), people are using it as evidence that "Mental health claims are up in kids."

Why is that wrong? Let's break it down.
2/ What is it?

It's an insurance report that does a breakdown of 32 BILLION claim records, looking at month-to-month changes Jan-Nov 2019 vs 2020. It focuses on pediatric (13-18) mental health insurance claims:

* overall
* self harm
* overdoses
* diagnoses
3/ This very important part of the methodology is at the heart of the confusion on how this paper is being reported.

It is NOT looking at raw #'s increasing, it's looking at percentages of overall claims.

In other words, what % of claims were for mental health.

1/ ***PERSONAL THREAD***

I have a condition called "Prosopagnosia" or "face blindness." It's a neurological disability my brain literally just does NOT TELL ME if I should recognize a face or not.

New hairstyle? new person!
Hoodie? no recognition!
Formal setting? who is that?
2/ Until I knew what this was, I was TERRIFIED of meeting or running into people. I would always criticize myself for "forgetting names" or "not being polite" when someone would tell me "hey, why didn't you say hi?" or "what you're just gonna walk by me?"

I felt rude. Uncaring.
3/ I went to med school! Oh god! Surgical masks and hoods. Scrubs. Everyone looked EXACTLY (not sort of) the SAME! My bosses would "pop by to ask me a question" and I wouldn't even recognize who they were. "Can you email me later?" "uh... sure... [oh no, who do i email?]"

This week: a lot of famous medtwitter accounts "oh sorry I've been away for a bit did I miss anything important? 😅"

Cowardice.
This week a major medtwitter/tiktok influencer was accused with evidence of serious sexual harrassment and assault. One of the major figures of medtwitter, @choo_ek (who I looked up to immensely) is named directly in the lawsuit. There may be more to the story. It's a lawsuit.
But it is crucial that we unequivocally stand up and tell all vicitms that the system failed this person, that when they report things to program directors + residency supervisors there should be mandatory actions taken, and that we cannot in any way discourage people reporting.
