DR CHRIS MACKIE (@Healthmac) is London’s Medical Officer of Health and a government advisor.

Yesterday, he said schools being open, “SLOWS the spread of COVID.”

For context, let’s look at 23 other times he misused data or gave a bad unsupported take.

When you’re in a position of power people rely on what you say.

They don’t need your ego and “hot takes” to override what your supposed to do:
a) Tell the truth
b) Keep people informed.

Yesterday’s tweet on schools was one of your most dangerous yet.

Shameful misinformation.

You gotta think about this one carefully!

Imagine you go to the doctor and get tested for a rare disease (only 1 in 10,000 people get it.)

The test is 99% effective in detecting both sick and healthy people.

Your test comes back positive.

Are you really sick? Explain below 👇

The most complete answer from every reply so far is from Dr. Lena. Thanks for taking the time and going through


You can get the answer using Bayes' theorem, but let's try to come up with it in a different —maybe more intuitive— way.

👇


Here is what we know:

- Out of 10,000 people, 1 is sick
- Out of 100 sick people, 99 test positive
- Out of 100 healthy people, 99 test negative

Assuming 1 million people take the test (including you):

- 100 of them are sick
- 999,900 of them are healthy

👇

Let's now test both groups, starting with the 100 people sick:

▫️ 99 of them will be diagnosed (correctly) as sick (99%)

▫️ 1 of them is going to be diagnosed (incorrectly) as healthy (1%)

ADHD, a thread (1)
If you have #ADHD & are struggling please know you’re not alone. This week on @Overview, we're talking about living w/ ADHD & Anxiety during the pandemic & many the stigmas & misconceptions that making things worse.

I was diagnosed w/ ADHD when I was 7. And in so many ways it’s been a blessing. I love my energy, the hyper-focus, the calm I feel in chaos, the ability to & feel emotions so intensely. It’s allowed me to to see the world differently be in a constant state of wonder.(2)

But realizing all that has been a long, difficult journey so figured I’d share some of my own struggles as well as the resources from @HowtoADHD because Jessica's channel has been a game-changer for me.(3)

First off, #ADHD Attention Deficit Hyperactivity Disorder is a dumb description. It implies a deficit in attention & always hyper people. ADHD is a spectrum, & what we all have in common isn’t that we can’t pay attention. It’s that we have trouble controlling our attention.(4)

There are amazing analogies out there, like trying to watch 6 TV’s at once when someone else controls the remote. Or like driving a race car on city streets and spinning out whenever you try to turn.

The #RELAx trial has been published today in @JAMA. It was coordinated by Anna Algera. This thread is to explain the rationale, what we did, the findings and the meaning.
The rationale of #RELAx is based on the following

First, there is NO adequate evidence on the level of PEEP in non-ARDS patients. Most of the studies are old, conducted in post-surgical patients (short-term ventilation), and were not powered to detect differences in patient-centered

Second, despite the absence of evidence, the levels of PEEP used in non-ARDS patients increased over years, from 5 to 7/8 cmH2O, probably as a reflection of studies and practice in ARDS

Third, one IPDM showed that higher levels of PEEP could benefit more severe ARDS patients. However, opposite trends (higher mortality and longer ventilation) were found in mild ARDS with higher PEEP (despite not powered to be statistically

Fourth, most of the weaning protocols include PEEP ≤ 5 cmH2O as a criterion for readiness to wean. Theoretically, a standardized liberal strategy of higher PEEP could delay weaning in some

is ADHD a mental illness ?

a thread

ADHD is a neurodevelopmental disorder - people with it are born with it and it cannot be altered because it's part of their brain structure and is seen on brain scans. ADHD is also linked to premature births and hypothyroidism during pregnancy, among other things

from the WHO website: "neurodevelopmental disorders are disabilities in the functioning of the brain that can affect behaviour, memory and/or ability to learn."

neurodevelopmental disorders are not caused by external/environmental factors. you cannot *develop* these conditions

mental illness is a general term for a health problem that significantly affects how someone feels/thinks/behaves. mental illnesses cause suffering to those who experience them, as well as often their loved ones. ADHD does not directly cause suffering.

neurodevelopmental disorders are not mental illnesses. ADHD however, does make it more likely for a person to experience mental illness. ADHD can cause dysfunction and stress, but more often than not this comes from lack of accommodation rather than the symptoms themselves.

A staple of anti-lockdown conspiracism in yoga/wellness is that public health measures are oppressive, authoritarian, and stifling what it means to be human. Masks suppress identity and speech. Vaccines assault the sovereign body. Influencers must rise up against tyranny! /1

Ironically, pandemic management in economies where yoga/wellness is lucrative has been a neoliberal, choose-your-own-adventure mess in which centre-right governments barter with public health to enact a patchwork of half-measures that punish the poor and marginalized. /2

The goal is not universal health rights, or protecting medical systems, or saving as many lives as possible. The goal is to return to business-as-usual, using public health as a pit stop on a productivity race off a cliff. The ice caps aren’t melting fast enough, I guess. /3

Right-leaning governments, like influencers, have assessed the COVID threat with the magical bias of limitless optimism. Then they work to normalize COVID casualties as a new cost of doing business. *This* is what alt-healthers and Qamoms call “socialist”, or “communist”. /4

Centre-right governments and wellness influencers share a goal: get back to the optimism of making productivity heroic and consumption virtuous, without any reflection on structural issues of injustice, or what universal health care funding and standards would look like. /5

Eri Katha Ramar Temple
Maduranthakam

Eri Katha Ramar temple is located at Maduranthakam near Chengalpattu of Tamil Nadu. Beautiful Kodanda Ramar of about 8ft holding Ma Sita's hand & with Lakshmana. This temple story is connected with Sri Ramanujar.
@LostTemple7


It was here Periya Nambigal performed Pancha Samskaaram to Ramanujar under Magizham tree.
Sri Ramanujar was on his way from Kanchipuram to meet Sri Periya Nambigal at Sri Rangam to become his disciple. Sri Periya Nambigal also started towards Kanchipuram to meet Ramanujar.


They both met here at Madurantakam.
Small Mandapam where Ramanujar undertook Pancha Samskaaram is seen in the temple. Separate sannidhi is for Periya Nambigal & Ramanujar & this is the only temple where Ramanujar is seen as a Grahastha (married person) and not in Sanyasa kolam.


Story says about an incident which occurred during British rule. The Madurantakam lake bund was about to breach, due to heavy rain & village will be flooded if it happened. Dt collector was Cl. Lionel Blaze who took efforts to protect the bund & asked for the piles of stones


in the temple to protect it. But it was meant for Janakavalli ( sita) Thayar sannidhi which faced shortage of fund. Lionel Blaze prayed Sri Ramar to save the bund and if so he will provide fund to construct.
That night he saw in the lightning, Sri Rama & Lakshmana walked along

Ameda Temple
Ernakulam, Kerala 🚩
#keralatemples

Ameda Ksetram is located in the banks of Vembanad Lake. Temple is very unique and Powerful Sarpa Kavu.
Parashurama did Prathishta here. Vilakku which was lighted by Parasurama is still seen inside the temple.


The oil from this lamp is given to bhakthas for recovering from illness.

Sthala puranam says that, Once, when Parashurama was travelling through Kerala, he reached this place. As it was evening, he stepped into the Lake for Sandhya Vandanam
At that Sapthamathrukkal 👇


(Brahmini, maheshwari, kowmari, vaishnavi, varahi, indirani and chamundi) were travelling there on a tortoise through the water. The tortoise was unable to move, because the Water had made its way for Parashurama. The place where the tortoise became Still came to be known as 👇


Aama Ni Nidayam' ( Aama means tortoise) and later become ‘Ameda’. Parashurama came to know about the journey of Sapthamathrukkal. Thus, he did Prathishta for the Sapthamathrukkal here.
7 forms of Aadi Parashakthi are Sapthamathrukkal. Veerabhadra and Ganesha have Sannidhi here.


The main Garbhagriham in the temple is the Sapthamathrukkal. There are Sannidhi to Nagas, Nagayakshi and Vishnu too. Sarparadhana or snake worship is done here. Naga Panchami is famous here. Those who have Naga Dosham come here and get relieved of their Doshas.

Starting my 2nd thread on Sringeri Parampara. This will cover the Jagadgurus after Sri Vidyaranya to Sri Shivabhinava Nrisimha Bharati.

It is really very tough to match the brilliance and achievements of Vidyaranya. After whom came 15 - Chandrashekara Bharati [1386-1389].

The next Acharya was Nrisimha Bharati [1389-1408]. Harihara raya found a town for this Acharya - Narasimhapuram. Acharya helped the king by guiding him in political affairs. He also initiated the kind with mahamantras for spiritual development.

Subsequent Acharyas were
15-Puroshottama Bharati [1408 - 1448]
16-Shankara Bharati[1448 - 1455]
17-Chandrasekhara Bharati II [1455 - 1464]
18- Nrisimha Bharati II [1464 - 1479]
19-Puroshottama Bharati II [1479 - 1517]

20-Ramachandra Bharati [1517 - 1560]. Sadashiva Raya was emporer of Vijayanagara during this time.
21-Nrisimha Bharati III [1560 - 1573]
22-Nrisimha Bharati IV [1573 - 1576]
23-Nrisimha Bharati V [1576 - 1600]

24-Abhinava Nrisimha Bharati [1600-1623]. When he visited Malahanikareswara temple for first time he noticed there was no Vinayaka there so he took piece of turmeric and drew outline of Ganesha on a pillar and offered puja.

1/ Thread: "A Silicon Valley Ponzi Scheme"

Thanks to @chamath for laying this out in Social Capital's 2018 annual letter.

I've always appreciated his outspokenness.

2/ The hardest thing for most startups today is the path to market: first finding product-market fit & a way to reach customers, then building a ruthless machine to acquire, monetize & retain them.

3/ Because of this, when the VC industry invests capital into fast growing startups today, the plurality (if not majority) of invested capital will go into user acquisition and ad spending, for better or worse— usually worse.

4/ Todays massive venture-backed advertising, sales, and user acquisition playbook has morphed into one that champions growth at any cost.

This is creating a big bill that will soon come due...

5/ Ad impressions and click-throughs are bid up to outrageous prices by startups flush with venture money, and prospective users demand more and more subsidized products to gain their initial attention.
