We really need to rethink this immediate availability of results in patient portals especially in oncology! Just had horrible experience with a terrified patient who saw results before I had chance to call her. All or none is horrible for any aspect of medical care

HRT is so needlessly underutilized in many of our young women with GYN malignancies for unsubstantiated “concerns”! And we likely remove ovaries in way too many women for the same “unsubstantiated concerns”

@NBSaphierMD The masks at school thing is so crazy. Example last night had daughter Vball game. None of the players using masks and huffing and puffing from running around yet the AD was a nazi with the few kids sitting in stands to mask up and then they all were together maskless outside!

need to ask that reviewers stop asking for power analyses in retrospective cohort series. It is nonsensical as retrospective analyses are merely hypothesis generating and there is nothing to be done about power. Can provide references. Folks really don’t understand “power”!

This new study confirms we have to make face mask-wearing the norm-> 99% compliance. As I + co-authors wrote, need to make mask-wearing easy and expected. Part of that takes leadership that walks the walk and listens to the science.

Cheapest way is to simply open RP space and find ureter. Takes 30sec per side to do this. Near impossible to injure something u can see. Cystoscopy use should be selective never routine.
