out of curiosity, how may people knew this? (dont be shy to say you did or didnt?)

My poverty education didn't ingrain this in me.

johnthurtjr  I did not +  
nlkrueger  i did not lol +  
ht3  you're definitely not alone lol +  
yotsubato  no idea +  
yotsubato  And its not in FA, so fuck it IMO +1  
niboonsh  i didnt +  
imnotarobotbut  Nope +  
epr94  did not +  
link981  I guessed it because the names sounded similar :D +8  
d_holles  i did not +  
yb_26  I also guessed because both words start with "glu"))) +11  
impostersyndromel1000  same as person above me. also bc arginine carbamoyl phosphate and nag are all related through urea cycle. +  
jaxx  Not a clue. This was so random. +  
wolvarien  I did not +  
ls3076  no way +  
hyperfukus  no clue +  
mkreamy  this made me feel a lot better. also, no fucking clue +1  
amirmullick3  My immediate thought after reading this was "why would i know this and how does this make me a better doctor?" +4  
mrglass  Generally speaking Glutamine is often used to aminate things. Think brain nitrogen metabolism. You know that F-6-P isn't an amine, and that Glucosamine is, so Glutamine isn't an unrealistic guess. +2  
djtallahassee  yea, I mature 30k anki cards to see this bs +3  
taediggity  I literally shouted wtf in quiet library at this question. +1  
bend_nbme_over  Lol def didn't know it. Looks like I'm not going to be a competent doctor because I don't know the hexosamine pathway lol +1  
drschmoctor  Is it biochemistry? Then I do not know it. +1  
snoochi95  hell no brother +  
roro17  I didn’t +  
bodanese  I did not +  
hatethisshit  nope +  
jesusisking  I Ctrl+F'd glucosamine in FA and it's not even there lol +  
batmane  i definitely guessed, for some reason got it down to arginine and glutamine +

Why not PGI2 by way of ASA? Especially given other answer choices of proteins C + S: doesn't warfarin also suppress these?

imnotarobotbut  Protein C and S are ANTI-thrombotic, so although Warfarin does decrease them, they wouldn't decrease the patient's risk for thrombosis +  
epr94  the question ask "suppression" of which one will decrease risk of thrombosis if you suppress C and S which and anti-thrombotic you get thrombotic +

Elevations in body temperature occur when concentrations of prostaglandin E(2) (PGE(2)) increase within certain areas of the brain.These elevations alter the firing rate of neurons that control thermoregulation in the hypothalamus.. It is now clear that most antipyretics work by inhibiting the enzyme cyclooxygenase and reducing the levels of PGE(2) within the hypothalamus.

yotsubato  Ugh, again a concept NOT in UFAP anywhere. Bites me in the ass every time +3

Can anyone explain why this is not a pituitary adenoma? Is it just a lack of other symptoms?

benzjonez  I think that they just wanted you to notice the **calcifications**. Per FA, "calcifications are common in craniopharyngiomas," whereas I don't think you'd expect to see calcifications in a prolactinoma. +10  
epr94  also the option is prolactinoma not broad pituitary calcifications and he doesnt show any specific signs of high prolactin +  
madojo  It says hes coming in for constituional delay in growth and puberty, i took this to mean that he had low LH, FSH due to decreased GnRH from the prolactinoma. Why did they have to say low-normal serum gonadotropin, why not just say normal? fck u nbme +

ac3  @madojo I believe since suprasellar tumors can cause a mass effect on pituitary gland to decrease gonadotropin levels. Where as prolactinoma causes a rise in prolactin which downregulates gonadotropin secretion. Please correct me if I'm wrong +1
