So this weekend you heard from our friends @BukuRenal that mismanagement of IV fluids can cause harm.

A group we’d like to highlight who can come to serious harm from ⬆️/⬇️ fluids is patients with

💦DIABETES INSIPIDUS 💦

See below 👇

#medtwitter #FOAMed

 Diabetes insipidus (DI) is the inability to hold onto water due to lack of /resistance to ADH.

Remember ADH is released as serum osmolality ⬆️ to ⬆️ renal water reabsorption, but in patients with DI this doesn’t occur and so they pass large vol watery urine - can be >10L/day!🛁
Note diabetes insipidus has nothing to do with glucose/sugar like diabetes mellitus! ⛔️❌⛔️

Misunderstandings are so common (even with HCPs) that there is a campaign to change the name to "pituitary insipidus"

#NoTimeToDI
Cranial DI (ADH not released) is usually due to pituitary/hypothalamic surgery, infiltration (inflammation/malignancy - rare) or head trauma. Can also be genetic.

Pituitary adenomas themselves can cause lots of hormone dysfunction, but don't typically cause DI.
Nephrogenic DI (ADH resistance) can be caused by
- renal disease
- electrolytes (⬇️ K, ⬆️ Ca – hence why hyperCa is dehydrating)
- drugs - can be seen with up to 15% of people taking LITHIUM 💊
Outwith the neurosurgical ward, you are most likely to come across patients with a prior established diagnosis of DI.

They may have multiple other hormone deficiencies (e.g. cortisol, thyroid, sex hormones, growth hormone).
When well, people with DI can usually manage their fluid balance (and sodium) by drinking in response to thirst.

Adding synthetic ADH (desmopressin) – nasal spray or tablet – also helps by ⬇️ UO and so ⬇️polyuria/nocturia when given at🌛 - can be very important for QOL!
🏥In hospital this balance can go wrong:⚠️

– ⬆️ fluid losses (e.g. fever, vomiting)
- ⬇️access to meds and/or fluids (esp if confused, drowsy, NBM etc)

= profound dehydration and ⬆️⬆️ Na despite “reassuring” UO

Sadly this has led to several deaths.
So what can you do?

1.RECOGNISE DI – from PMHx, drug hx, medic alert, electronic record alert and SHARE INFO WITH TEAM 📢

-> rare condition often = ⬇️ awareness

2.Give usual desmo - 🔔CRITICAL MED🔔

3.Alert endo team 📞

4.Monitor – Na AT LEAST DAILY, fluid in/out
⬆️Na (i.e. dehydration) is concerning:

1.Consider ⬆️ level care and d/w specialist asap

2.Give desmo – can be given IV/IM (get help w conversion!) if usual routes not available 💉

3.Aim to bring down Na SLOWLY with fluids (<10mmol/24h)

5.👀 Na e.g. 4hrly, fluid in/out..
⬇️Na can also occur:

- those taking Desmopressin will struggle to excrete excesses if given too much fluid
- d/w specialist - may require Desmopressin dose change or delay to allow for controlled diuresis

Allow pt to take fluid orally (v IV) if possible so can self-regulate 👍
How confident are you in caring for people with DI?

Did you know the Society for Endocrinology has published advice about DI for non-specialists?

You can find that here 👇

After therapy sessions, it is occurring to me how my parents and maybe most desi parents don't really grow as parents. For example, a person would be a very different to a baby and to a teenager because the needs and vulnerabilities are so different.

But here, I feel that growth for parents stagnants sometime around when a child is 12-13. None of our parents really talk to us about puberty and growing up. None of us are taught or can talk about relationships because of moral reasons. So what do you have?

You have parents who are still parenting their adult children like kids, not apologising to us but asking us to eat, reminding us to wear jackets, locking up cars. They care. But they are coming from a care where the parent is always concerned about keeping the kid safe and alive

which imo really reduces the kind of parental advice and care one needs as an adult. Because adults know enough about the world to no longer be infantilized but we still have parents who expect us to be the same children because they're still the same kind of parents.

This is why so many of our parental relationships are strained or just based on civilities. We're forced to hide a lot from them because parents refuse to grow as parents and acknowledge us as adults. How many of us are still lectured, have curfews, other restrictions?

Eight years ago, Spencer Cox died of #AIDS. He had access to #antiretroviral therapy, but in his own struggles with #depression and substance use, he stopped taking them. 1/

Spencer left college, dropped out like me in the 80s, and we both found ourselves in @actupny where we joined the Treatment and Data Committee, doing battle with drug companies, the @US_FDA, the @NIH on a quest to save ourselves and our friends from near-certain death. 2/

Now everyone knows what those dark days before the advent of antiretroviral therapy were like. Waves upon waves of dying friends. A government who couldn't care less for the sick and dying. 3/

All this has happened before, and all this will happen again. AIDS. #COVID19. The next pandemic. The fire next time. 4/

And it changes you. Seeing so much death so young. Seeing those in power turn away from the catastrophe, even joke about it (find, listen to the tape of Larry Speakes in Oval Office w Reagan laughing about AIDS). 5/

this simple, counter narrative fact keeps cropping up all over the world.

hospital and ICU utilization has been and remains low this year.

it's terribly curious that so few of these monitoring tools provide historical baselines.

getting them is like pulling teeth.


we might think of this as an oversight until you see stuff like this:

this woman was arrested for filming and sharing the fact that their are empty hospitals in the UK.

that's full blown soviet. what possible honest purpose does that

this is the action of a police state and a propaganda ministry, not a well intentioned government and a public heath agency.

"we cannot let people see the truth for fear they might base their actions on real facts" is not much of a mantra for just governance.


90% full ICU sounds scary until you realize that 90-100% full is normal in flu season.

staffed ICU beds are expensive to leave empty. it's like flying with 15% of the plane empty. hospitals don't do that.

and all US hospitals are mandated to be able to flex to 120% ICU.

the US is currently at historically low ICU utilization for this time of year.

61% is "you're all going to go out of business" territory as is 66% full hospital use.

can you blame them for mining CARES act money? they'll die without it.

Ashtangha Yoga or the eight limbs of Yoga-


Many people think Yoga is just an Indian physical exercise but that's wrong. Yoga is a way to connect with the Supreme in Hinduism and attain Moksha(liberation).
The proper yoga as described in Hindu scriptures consists of 8 limbs:

1) Yamas- They are the 5 ethical rules of Hinduism. The 5 Yamas are:
i) Ahimsa: Nonviolence (this also includes not eating meat)
ii) Satya: truthfulness
iii) Asteya: non-stealing
iv) Brahmacharya: chastity, sexual restraint
v) Aparigraha: non-avarice, non-possessiveness

2) Niyamas- They are the 5 "do's". The five Niyamas are:
i) Shaucha: purity of mind, speech and body
ii) Santosha: contentment
iii) Tapas: austerity, self-discipline
iv) Svadhyaya: study of Vedas(Holy books of Hindus)
v) Ishvarapranidhana: contemplation of the Ishvara (God)

3) Aasana or the physical yoga-
Asana is a posture that one can hold for a period of time, staying relaxed, steady, comfortable and motionless. The aasana postures are believed to have been given by Mahadeva (Hindu God) himself. Hatha Yoga Pradipika mentions 84 aasanas.

Our conscious experience exists. In fact, it's the only thing you can directly observe, as everything about reality and how we perceive it is filtered through how our brains process stimuli and information. You are the only one who can define who and what you are.

Don't get me wrong, I am a materialist who believes the universe exists in the absence of beings who can observe it from an intelligence standpoint, but we are all collections of atoms, our function governed by chemical processes, not perfectly replicated by the process of birth.

Our means of DNA replication is imprecise because of billions of years of random evolution. We are on one branch of many, and there is countless variation in how all living beings are formed, and how we classify traits of those creatures, including sex and reproduction methods.

It would be an error to say that people who are intersex and/or transgender are the results of mistakes or errors in reproduction, because it implies DNA is "trying" to create a binary model of people and sometimes gets it wrong. It doesn't "try" to do anything; DNA != conscious.

Rather, our biological blueprints are not precise, and this is true for all living things. We can crossbreed plants and animals because of that imprecise nature, it's responsible for what we perceive as the "races" of people, etc. We can observe variation everywhere.

SRI CHAMPAKADHAMA SWAMY, BANNERGHATTA HILL, BENGALURU (KAR)
#bharatmandir

The shrine is dedicated to Sri Vishnu along with Devi Lakshmi and Bhoodevi.
It is built in an area full of Champaka trees.
As champaka flowers are offered to Sri Vishnu here, it is called Champakadhama.


It is believed that King Janmejaya had sarpa-dosha. To get rid of it, he took bath in the nearby pond. He emerged with a golden body and sarpa-dosha was also removed. The pond is called Swarnamukhi and believed to have curative powers.
Sri Vishnu murti was consecrated by him.


It is also believed that this forest area was the Dandakaranya where Sri Ram stayed in exile.
Some believe that the original shrine was built by Pandavas.
The pushkarni/pond is emptied once a year so that the rock at the bottom (which has image of Anjaneya) may be worshipped.

@FionaPearman @ScottMorrisonMP Morrison is our statue of unempathic neoliberalism - erected by evangelical and corporate Australia to celebrate their victory over compassion, equality and secular humanism. 

Hopefully it gets pulled down like the statues of dubious heroes of oppression from an earlier age.


@ScottMorrisonMP The two-party-preferred system in 
Australia politics isn’t working for people, and it sure isn’t working for the planet.

@ScottMorrisonMP My collapse of faith in our democracies isn’t an accident. It’s one of the central victories of the neoliberal project, delivered through two generations of privatisation, outsourcing and deregulation, underfunding of government services (locked in by tax cuts),...

@ScottMorrisonMP restricting freedom of information, targeting whistleblowers and raiding the media who report on them, delegitimising and gagging public interest advocacy, and criminalising protest.

@ScottMorrisonMP Politics in Australia today relies hugely on the fact that most people don’t know most of what’s going on so as to get away with stuff that couldn’t be done under real scrutiny we have seen a clear example of this with the National Coronvirus Cabinet.

PAKISTAN-INDIA WATER ISSUES – HOW INDIA STOPPED WATER IN PAKISTAN's CANALS IN 1948

...the historic distribution of common waters undisturbed.

India's action was therefore in flagrant disregard not only of international law n morality, but of her solemn commitments with Pakistan and a gross violation of this country's historical rights over common waters.

1. Friends Of The Great Planet Earth!

Everything You Seek Is Already Within You!  Each Waking Dream Has False Teachings That  Say There Is A Special Place 'Out There' In The Skies Where People Go That Follow A Certain Doctrine.

2. And Those Same Teachers Explain There Is A Place Of Torment For Others That Arrived On A Different Part Of The Planet And Were Taught A Different Doctrine.

There Is ONE Creator That Has Been Named By Many. It Would Be Loving To Honor And Respect Another's Beliefs,

3. As In Truth, Many Have Lived In Multiple Cultures With Many Beliefs That Now Are Judged! Incarnating Over And Over Is The Joy Of The Soul Experiencing Life! The Soul Fully Understands This Is A Human Experience.

4. Wouldn't It Be Much More Relaxing And Fun To Allow Others Their Freedom, Just As You Want Yours?  Yes Indeed!  Relax And Flow!

Since The Very Beginning Of Your Self-Awareness As An Incarnate Being, You Have Probed Your World For Clues To The Meaning Of Your Existence.

5. You Have Looked In Every Conceivable Crevice And Pondered The Vastness Of The Infinite Cosmos. You Have Scrutinized The Spiritual Wisdom That Was Forthcoming From Those Who Believed Themselves To Be Knowledgeable About Such Matters.
