Dr. Neil, you are awesome! I am so glad I discovered your channel as I am getting ready for my step 1 exam this summer. I was wondering if you were or had made a video on pediatric brain tumors? I loved your adult one and couldn't find the pediatric counterpart. Additionally, if you have any material on arrhythmias and antiarrhythmic drugs that would be extremely helpful. You are the GOAT

@@RandyNeilMD Bradford hill criteria is being tested a lot these days They also added this to first aid 2021 edition pg 261

[@nishatshama6652]

from first aid 2021 Bradford Hill criteria A group of principles that provide limited support for establishing evidence of a causal relationship between presumed cause and effect. Strength Association does not imply causation, but the stronger the association, the more evidence for causation. Consistency Repeated observations of the findings in multiple distinct samples. Specificity The more specific the presumed cause is to the effect, the stronger the evidence for causation. Temporality The presumed cause precedes the effect by an expected amount of time. Biological gradient Greater effect observed with greater exposure to the presumed cause (dose-response relationship). Plausibility A conceivable mechanism exists by which the cause may lead to the effect. Coherence The presumed cause and effect do not conflict with existing scientific consensus. Experiment Empirical evidence supporting the presumed cause and effect (eg, animal studies, in vitro studies). Analogy The presumed cause and effect are comparable to a similar, established cause and effect.

[@ЕкатеринаСерикова-ф5з]

I have a question - why it is not birth control measure? It is classic picture for country with birth control. Like China. One baby per family, well they were doing ultrasound to find out the gender and after termination of pregnancy if it is a girl( sad situation). But I see why work migration is the right one but birth control is quite good answer too.

How low is considered low life expectancy?? like in this Q?

Sir, Thank you so much for all you do for us🙏 Sir can you share your notes link please.

[@fernandom6]

I had a question on my step 1 test with an expansive graph and I really had issues deciding between 2 answers: (I’ll write a similar example of what I can remember) Where should the government invest $? a- Hiring more nurses/getting more primary care professionals (I thought this was a good answer since it could help with the low life expectancy) B- Hire/invest more on kindergarten teachers and education (I chose this one since the infant population was so high) Again, don’t know if I this was the right answer.

[@austinnoelvideoextravaganz1455]

You never should hire more teachers man, answer would be option a. The school system is turning into garbage and parents need to be homeschooling so never get more profs, I hope you passed though!
