Anybody who says “the #data don’t lie” either is ignorant or manipulative or both. The data are merely a tool that must be used responsibly & ethically to try to approximate “the truth” …some of which is unmeasurable (yet?). There are MANY #datascience methods & varying results
Everybody gets super excited about this new #AI #ML #machinelearning technique or that

You cannot build a RELIABLE house with low #quality bricks

First, look at the building blocks… meaning, how the #data fields are even defined & how the data are obtained

Who defined them?
I can’t tell you how glad I am that I have done coursework at both @MITSloan AND @StanfordGSB - Former immerses you in a ton of hands on analysis & options for analytic techniques useful in a #datascience job. Latter steps back to frame questions, assess missing data, biases.

#HistoryofEVT

It’s no secret that #EVT for AIS has been a complete game changer for the field resulting in dramatic reduction in death & disability

Join us to explore the #history of EVT in collaboration with @SVINJournal, to celebrate the inaugural issue Image
Many thanks to @Mahmoudneuro, #RaulNogueira and @DiogoHaussen whose review entitled:
👉“Tx Advancements in the Endovascular Management of Stroke” celebrates the advances in #ETV

1st #Fun fact: Interventional treatment of AIS dates all the way back to 1950s‼️
Sussman & Fitch reported 3 cases of IA infusion of fibrinolytics
Didn’t work 😫. Probably because they were performed in a non-hyperacute fashion
But this laid the foundation for years of refinement Image

While your surname will probably not help you to join the Olympics, your day of birth might 😅 #statistics #bias

We have a drug that protects from #HIV. True or False? #ph260720
My friend Steve texted me last year asking how he could convince his partner Ed to see a doctor.

Steve said, “Something weird is happening to him. He can’t walk, his speech is slurred, and his mood changes. He’s a totally different person.” #ph260720 #HIV
I asked him why Ed is reluctant to see doctors. Steve replied, “He has always hated seeing doctors because he feels judged by the health system.”

This is the story of Ed’s experience and how we could have prevented his death from #AIDS 8 weeks later. #ph260720 #providerbias

"#Data: a new direction" - a public consultation by @DCMS on "reforms to the UK’s #DataProtection regime":

gov.uk/government/con…

The consultation ends on 19 Nov 2021, and you can respond by e-mail to DataReformConsultation@dcms.gov.uk or online here:

dcms.eu.qualtrics.com/jfe/form/SV_4P… Image
A quick sample of initial reactions...

We're clearly going to be hearing a lot about #LegitimateInterests, as well as #commercial and #public ones. The real question being, how do this Government's interests actually align with YOURS?

140+ pages on a Friday is a lot to digest, but @lilianedwards' "penumbra of often futile determinedly populist ideas largely not evidence-based" seems entirely consistent with @DCMS's Drunkard's Walk through #data and #ID this past year...

‘…ask yourself if the authors are truly trying to inform their readers or if they are instead trying to advance a narrative that would be undermined if they fully enumerated how COVID-19 has harmed children.’

Is UK Paediatrics #SoMe governance dead? When will its leaders act against medics pushing misinformation narratives?

‘Doctors writing about COVID-19 and children have an obligation to inform their readers of essential facts.’ @jeremyphoward 👏👏

1/🧵Human Error in Decision Making and Judgment:
 
For those who loved @NobelPrize Laureate’s book Thinking Fast & Slow, there is a new Kahneman book called Noise reviewed @TheLancet. It’s worthy of a bit of commentary…

bit.ly/3hzD7RR

#MedTwitter #ScienceTwitter
2/In statistics, #NOISE refers to random scatter, ie, variations in our judgment that are NOT caused by individual judgment. #BIAS on the other hand is systematic deviation in judgment.
 
@nataliexdean @EpiEllie @f2harrell – teach us more & did you read Kahneman’s book yet?
3/ Kahneman himself (see quote in @TheLancet review👆) acknowledges that this book is somewhat data-o-penic. We need much more knowledge about “noise”…it’s a limitation in science at this point. In Medicine, he claims #Psychiatry is an extreme noise factory…@APAPsychiatric

1/What defines a sound investor? One who intuitively acknowledges their psychological biases and trades emotion for pure rationality. Ironic, isn't it?

Investors are driven by multiple unconscious biases. We wrote a thread🧵 on some of them. Thread starts
2/Let's start by defining what's an 'unconscious bias'. Also known as a cognitive bias, it's an error in judgement due to personal preferences leading to poor decisions.
3/*1.Overconfidence bias* aka I’m the next Warren Buffett
Placing too much faith in your knowledge leads you to think you're an expert investor with the Midas touch. Eg: A student omits studying entire chapters for an exam because "questions from these chapters will never come"

Had a fun time talking about #leadership in #STEM (at any stage of career), #BlackExcellence #WomenInSTEM #DEI #DiversityandInclusion to a range of students and faculty at @tennesseetech. Thanks for the invitation @JosephCSlater. Look forward to building further on this.
Talked about ways to take on community level leadership roles to develop skills in acquiring funding, managing a budget, team building, managing people, executing.

Know what you are good at and balance the rest with your team. Don’t try to be it all.
Particularly on #Twitter, being overt about terms like #bias or #BLM or #racism can result in blowback. That does not mean what you said was wrong rather others may have insecurity or have work to do. Manage your energy as an advocate. Avoid burnout.

I remember saying in a talk once:

“Bad intentions aren’t a prerequisite for something to be considered a #microaggression.”

Funny how our own words and lessons can come back to tap us on the shoulder.

Let me explain.
2/
All of our luggage was clustered near the front porch. It was about five minutes to the hour that we had to be fully vacated from the house that we’d rented for spring break.

Everyone was scrambling about and making sure we had everything after a lazy week of relaxing.

Yup.
3/
The hatch was up on the back of my car and my teen son was loading in bags with me.

That’s when I noticed a gentleman walking toward me from what appeared to be a truck filled with cleaning items. I could see that he was accompanied by some others gathering what they’d need.

This is VERY important because we already have a mistaken belief that being "a good person" or "having empathy" can erase or mitigate racial bias or disparity when study after study proves opposite. Now we're encoding bias into #algorithms and #AI that will be called #DataDriven
This is the new frontier of #systems driven #bias. Look at the demographics of who is in #technology and #BigDataAnalytics and #AI. Look at the reputation of culture of these spaces. This puts everyone at risk even if you think you "benefit" from the bias. Inaccuracy is harm.
Just look at the #COVID19 #pandemic. Who correctly predicted AND took correct actions for good outcomes?

The risk of the most vulnerable became YOUR risk

if your #sytems and #bigdata and #BigDataAnalytics fail to capture reality

your real life results will be failure.

1/ All teachers will have learners who aren’t meeting expectations.

Providing feedback in these situations can be tough, but is VITALLY important.

Hang with us, the #MedEdTwagTeam, and we will walk you through it on today’s #TweetorialTuesday!
2/ Today, we will discuss the “struggling learner”, a terrible phrase that shouldn’t be used.

From now on, we will be discussing the learner who isn’t meeting expectations (LWIME). This doesn’t label, and describes their current behaviors, not their potential.
3/ Can we define LWIME? Per @JenniferSpicer4 & @gradydoctor, you need a measuring stick to say whether a learner is, or is not, meeting expectations.

Great tools are the #ACGME Core Competencies or #CanMEDS Framework. You can further break this down by specialty #milestones.

There are 328,200,000 people in the USA.
Black Americans make up about 13% of the population
There are currently about 877K practicing physicians in the USA....
4% of the 877K are Black
ONLY 2% of physicians in the USA are BLACK FEMALES.
We are out there, serving our communities, taking care of the sick, the disinfrachised. Listening. Doing. Acting.
We are tired. We are only 13% of the population but we are dying faster and worse from almost every disease/disorder...
We know it isn't just race that determines these outcomes. Its a long standing system of #bias #structuralracism and social determinants of health that make this an almost impossible battle to win....
