📚 Did you know that back pressure is a high-yield physiology concept that shows up across organ systems on the USMLE? 🔥
When flow is blocked, pressure builds upstream…and that pressure can damage the structure/function “behind” the obstruction.
🗓 Urology:
BPH
⦿ bladder outlet obstruction → ↑ intravesical pressure → bladder hypertrophy, hydronephrosis, and postrenal AKI.
🗓 Cardio:
Congestive heart failure
⦿ poor forward flow → venous backup (“back pressure”) → pulmonary edema (left) + peripheral edema/ascites (right).
🗓 GI:
Intestinal obstruction
⦿ proximal buildup → distention + vomiting; if the obstruction is distal to the ampulla of Vater, vomiting becomes bilious.

Me: 0…(after skimming the abstract and choosing vibes)
📚 Did you know that Polycystic Ovarian Syndrome is tested more than three times across NBMEs for USMLE Step 1 and Step 2 CK? 🩺 As of May 2026, the term PCOS is now PMOS (Polyendocrine Metabolic Syndrome). This is a major update in women’s health—this diagnosis now encompasses many of the comorbid factors patients experience. ✅ For your USMLE exam, know the Rotterdam Criteria: • Hyperandrogenism • Oligo-/anovulation • Polycystic ovaries on ultrasound 🧠 Management starts conservatively with weight loss, then progresses to oral contraceptives and spironolactone, plus ovulation induction agents like letrozole and clomiphene for patients who desire pregnancy!

If you’re taking the USMLE in May (or later), there are some important changes you must be prepared for! 🚨
As you’ve probably heard, Step 1 and Step 2 CK are moving to 20-question blocks — each functioning like a 30-minute sprint.
If you’re in dedicated right now, don’t only practice 20-question blocks because of this change.
Create a few blocks which are:
✅ 20-questions
✅ Back-to-back 20-question blocks for stamina
The key: your break time is not changing.
In order to pass & score high, you want to be very mindful of pacing, transitions, fatigue management, and break strategy.

Hantavirus causes a deadly hemorrhagic fever with renal syndrome! 💀
The USMLE wants you to know that the transmission is going to be from rodent urine or f***s. 🐭
Finally, you must know that hantavirus is part of the Bunya virus family! 🧬
Hope this helps in your studying!

The 3 GI diseases you NEED to know for the USMLE:
Celiac Disease 🍞
Autoimmune reaction to gluten → villous atrophy (proximal small bowel)
Key: chronic diarrhea, weight loss, 𝐢𝐫𝐨𝐧 𝐝𝐞𝐟𝐢𝐜𝐢𝐞𝐧𝐜𝐲 + anti‑tTG/anti‑endomysial
Crohn’s Disease 🧱
Transmural, skip lesions (anywhere mouth → a**s) → fistulas/strictures
Arrow question: RLQ pain, 𝐧𝐨𝐧𝐜𝐚𝐬𝐞𝐚𝐭𝐢𝐧𝐠 𝐠𝐫𝐚𝐧𝐮𝐥𝐨𝐦𝐚𝐬, creeping fat
Ulcerative Colitis 🩸
Mucosal/submucosal, continuous from re**um → proximal colon → toxic megacolon
Key: bloody diarrhea, p‑ANCA, increased risk of colon cancer + PSC
The transmural vs mucosal difference (and skip vs continuous) is clutch for Step 1!
