English is not my first language.

I think the reason that not using PPI is the Q mentions other adverse effects than gastric burning:

"... has severe gastric burning and discomfort... THESE adverse effectS".

Therefore, I guess PPI can relieve gastric burning but not discomfort, so we give the patient what he is lack of.

Per FA, should aminoglycosides be used in gram negative infection? S.viridans are Gram positive.

I think the unaffected 1,3 (I, female) is due to incomplete penetrance

The OR in the upper left 22 table is incorrect, which should be 6 (726/36*2 =6), not 1. This means the OR of "ate cookies" does not change after stratification by "drank milk", so "drank milk" is not a confounder, and "ate cookies" is independently asso w/ EHEC outbreak.

On the other hand, OR for "drank milk" changed a lot (from 3.9 to 1.0), which indicates "drank milk" might be a confounder and, therefore, is not independently asso w/ EHEc outbreak.

English is not my first language, but would it be possible that adherence is not equivalent to adhesion and somehow interchangeable to aggregation? I feel like doing a reading comprehension test, not USMLE.

Right gastroepiploic V can also be drained into its counterpart on the left, but short gastric V does not have anastomoses, so the varices of short gastric V leads to bleeding.

I got this Q wrong. I was wondering why this patient “has no personal or family history”. Hereditary spherocytosis should be a AD disease, so, generally speaking, this diz should be seen in each generation, right?
