Time ⏰ for Part #2 of the Tweetorial 🧵 on the DDI btwn PHT & VPA with a focus on drug metabolism 💊🔄

If you haven’t seen it yet - check out Part 1 by @JimmySuhMD on the albumin interaction btwn PHT & VPA
 
However, that’s only half of the story!⚠️
 
1/n First, let’s discuss basics on phases of drug metabolism 🔄
 
Phase I: Oxidation (ex. CYP450 enzymes)
 
Phase II: Conjugation (ex. Glucuronidation)
 
🎯 Goal 👉🏻 covert drug to an active (pro-drug) or inactive metabolite and ⤴️ solubility ➕ ⤴️drug elimination via urine/bile

Let’s talk CSF 🧠 💦

☝️ What is it & why is it important?
✌️ Key considerations in CSF sampling 🧪 & analysis 🧐 for suspected infection 🦠

A #NeuroTwitter 🧵 inspired by bedside rounds with attending @BuslKatharina & NCC team👏🏻 So to start, what is CSF? 🤔

CSF▶️clear, sterile fluid secreted by choroid plexus 💦 in the ventricles ➡️circulates throughout the subarachnoid space🧠 & spinal canal🦴

⭐️Function▶️ protective barrier 🛡 provides nutrients 🍎& facilitates removal toxins/metabolic byproducts⚠️

Now that the salty🧂debate on the TYPE of fluid to use in the ICU has largely been solved, how about the RATE of IVF? 🤔

Back to the BaSICS💦

✅The Balanced Solutions in Intensive Care Study📖 (BaSICS) ▶️compared 333mL/hr vs 999 mL/h

Does IVF rate impact 90-day mortality? 🤔 💡 10, 520 ICU pts randomized 🏥

Fluid volume:

1162 mL in the SLOW infusion group 💦
vs. 1252 mL in the FASTer group

🛑NO difference in☝️ outcome: 90-day mortality (HR 1.03, CI, 0.96-1.11)

🛑No difference in✌️outcomes: RRT, AKI, ventilator free days, ICU/hospital LOS

Alert 🎙Pharmacy Grand Rounds Thread Ahead! 🚨

Last week I had one of my final presentations of the year! With a catchy title😉

Urine for an Update! Updates in the management of metastatic urothelial cancer

Hold your bladders, this is an extensive update! 😂
#oncopharm Image Bladder cancer can be divided into two ✌️subtypes:
1) Non-muscle invasive: encompasses in-situ and localized disease➡️5-yr OS >70%

2) Muscle invasive: encompasses regional or metastatic disease➡️5-yr OS dismal especially for metastatic disease 😔 Image

I would like to make a few points of clarification for yesterday tweet on Vasopressin for cardiogenic shock.

🔑 point: Vasopressin is not “preferred” nor 1st line in CS but “may be considered” in select cases

Please read further thread 👇🏻👇🏻 It should have stated “may consider” VP as the suggestion of benefit in the JAHA article on CS was based on theoretical benefit and a ☝️ post hoc analysis of the VASST trial which included septic shock patients, notably a VERY different pathophys than CS.

What factors do you have to consider while treating a cancer pt with a malignant pleural effusion and concurrent infection? 🤔

1/
🚨Cancer pts are at risk for MPE➡️consequence of metastatic involvement of the primary tumor in the pleura💨 💡Lung, breast, and lymphoma are the most common causes💡

Query of the pleural fluid with the use of the Lights criteria will help to determine the etiology (transudative or exudative)

Exudative=malignant OR infection

One of the criteria is a serum protein ratio >0.5

Abiraterone 💊 is an oral antiandrogen approved for metastatic hormone sensitive and castrate resistant prostate cancer

Why does abieraterone have to be coadministered with prednisone? 🤔 What if a patient wishes to avoid steroid therapy? 🤯

#oncopharm #pharmpearl Abiraterone is a CYP17 inhibitor that suppresses downstream non-gonadal androgen synthesis
As a consequence➡️ reflex↗️↗️ ACTH production leads to excess in mineralocorticoids

ESBL vs AmpC🦠what is the difference in resistance & tx?

Resistance
ESBLs ➡️ encoded by plasmid genes
AmpC ➡️encoded by plasmid genes OR "inducible resistance" via derepression of chromosomal🧬genes
⚠️can👀susceptible but resistance develops ON therapy! Treatment➡️Carbapenems➡️𝟏st line💊of choice

However➡️rate of carbapenem resistance is📈➡️today I was asked about cefepime tx

AmpC➡️typically resistant to some/ALL cephalosporins BUT cefepime is STABLE against AmpC! (unless other mechanisms of resistance are present)

History can teach us a great lesson here➡️As described in the @ACCP front line heroes page➡️pharmacists are undergoing heroic🦸🏻‍♀️feats&acts of bravery on a DAILY basis

Beyond COVID➡️we need to continue advocating for our profession to benefit healthcare & most importantly patients Similar to uncovering legendary figures like Rosie the Riveter who said “We can do it” does our profession need our own mascot?

Here is our proposed hero, let’s make them real because “we know” we can do this!
