- "Tirzepatide is a dual agonist"
👉It ↑GIP activity but GLP-1R agonism is less than that of endogenous GLP-1
- "Hypoglycemia is not a concern if you're not on insulin"
👉Risk of hypoglycemia ~1.4% vs. 0.2% in placebo in SURMOUNT-1

- "In this pt with uncontrolled #diabetes, A1c 7.4, we decreased glargine by 10% [when we started tirzepatide]"
👉 Not sure where the evidence is here, but the SURPASS-5 trial protocol reduced basal by 20% in participants with baseline A1c<8

Vancomycin is primarily effective against Gram positive bacteria ✅
No/clinically insignificant activity against most of the gram negative bacteria.🦠
Because of the large molecular size, vancomycin cannot penetrate the outer membrane of gram negative organisms. ❌

Yesterday, I completed my months-long quest to accurately identify all sci-fields emerging in WW other than the well-established Neuro ⬇️
For, it's been long since we noticed emerging scientific tangents that span diverse fields like: #ML, #Materials_Science, #Pharmacology, #Genomics, #Open_Hardware, etc
Awesome -- But, how does one possibly map all these frontiers without employing actual people to read and annotate dozens of hundreds of abstracts at a time?
I'll be adding short important points which would hopefully help in remembering certain concepts during #PLAB preparation, to this thread🧵every now and then as I take them out from my scattered notes. Feel free to comment your tips and tricks which would help others, as well 👇
Please don't take any of these as medical advice 😂🙏. Real life stuff is much more nuanced. These are just clinchers for the sake of the exam.

What's so good about LEV? First, some #pharmacology:
✅ Fast PO absorption
✅ 1:1 PO:IV 💉
✅ Few med interactions
✅ Can load for status epilepticus

This demonstrates the feasibility of a programme I’ve set forth, for the ‘exact’ simulation of ANY dose-escalation design.
Influenced by @MarkusTriska‘s exacting perspective on ’exactness’, however, I now use the more precise term ‘MCSE-free’. 2/

@MarkusTriska ‘MCSE-free’ in turn alludes to the title of recent work by Thomas M. Braun, from which I adapt my application.
(Braun’s mean-field approach truly can be called ‘simulation-free’, whereas I DO simulate the trials—just without Monte Carlo error.) 3/

Had a chance to read in detail this morning, and oh boy do I love this paper! While depression research and MOA of antidepressants are not really my thing now, the whole paradox of how the so-called SSRIs work is a major reason that I got into neuroscience to begin with.
First learned about this in neuropharmacology class as an undergrad @UT_Dallas in 1996 or so from a chapter in Basic Neurochemistry written by Alan Frazer and Julie Hensler. I was captivated by this paradox and decided to apply to @UTHealthSA #Pharmacology for grad school.
For those interested in #cannabis #pharmacology review: ncbi.nlm.nih.gov/pmc/articles/P… “in this short review we tried to shed light on the potential drug interactions of medicinal cannabis” 1/4 @division_55
“potential outcome of a drug interaction can be additive (1 + 1 = 2), synergistic (1 + 1 > 2), or antagonistic (1 + 1 < 2). Therefore, a drug interaction may lead to an enhanced drug response or modified or unexpected adverse reactions” 2/4
“Cannabis has been used in various forms as crude extracts or purified ingredients (different THC/cannabinoids ratios); therefore, drug interactions caused by cannabis depend not only on drugs involved but also chemical components/profiles of the cannabis preparations used” 3/4

ATTN #CBD stakeholders: @US_FDA today holding scientific conf. on CBD/other #cannabinoids. I'll be live tweeting throughout. Not sure we'll get much insight on immediate path forward for consumer products but I'll share noteworthy observations. Agenda: bit.ly/3pHXU8V
I'll be paying particular attention to @DrAbernethyFDA's remarks at 9:05a (head of #FDA's #CBD Policy Working Group) and @DThrockmortonMD's keynote at 9:15a (one of Agency's principals for regulating R&D, manufacture & marketing of #cannabis & cannabis-derived #drug products).
My journey to my #PhD program was an absolute #strugglebus. I graduated with a 2.75 GPA from @GeorgiaTech. Most grad applicants have a 3.5 or higher. #Yikes
I applied anyway 🤷🏾♀️🤷🏾♀️🤷🏾♀️ (I didn't get admitted into any programs - post bacc, M.S., or PhD) #AcademicChatter

Fortunately, my mentor @RaquelLieberman gave me the opportunity to work as a #research technician in her lab for 2 yrs to gain the experience I needed for grad school.
This is when I first started studying essential pathways that we could disrupt to kill disease causing bacteria

After working in her lab for almost 2 years..I reapplied again. This time I felt VERY confident I was ready for the #PhD.
I was denied admission to every single grad program I applied to (including the one I'm in now).

TLDR: Your ♥️ is regulated by an electrical impulse that travels throughout the ♥️. When this electrical signal is disrupted, this causes your ♥️ to beat irregularly (arrhythmia) & ineffectively pump blood throughout your body...you can imagine that this isn't good 😬.
This irregular heart beat can cause your ♥️ to stop beating entirely = #suddencardiacdeath 🪦! In @EphysWiz's lab, my #PhD focuses on developing a therapy that can correct disrupted electrical activity of the ♥️ to restore healthy heart function. @BlackInCardio #STEMNoire

I listen to ~90 #Podcasts on a (semi) regular basis. Let me give you a rundown of ALL of them and why you should listen to some amazing #FOAMed, especially for all the new #EmergencyMedicine interns. #FOAMed #MedEd #medtwitter
First of all, you need a good podcast app. I absolutely love Downcast. Great app, gives you more control over playback, downloading, and allows you to categorize your podcasts into playlists (picture 2). This is where you get to customize your #FOAMed experience! #medtwitter
