Genetic testing: there are so many tests to choose from! Karyotype, Microarray, Whole exome sequencing, they all sound the same. What's the difference? Read on and hopefully things will become clear... 🧵
#meded #tweetorial #medgen First, let's remember that our DNA is found in really nice organized packages called chromosomes. Humans have 23 pair of chromosomes = 46 in total. Each chromosome has a short arm (p=petit) and a long arm (q=comes after p).

RE: Race descriptors- While there is a place for them (like when discussing social determinants), it is not useful when stratifying cohorts as it is not binary nor a great surrogate for ancestry. We can do better!

ALSO: We need to stop using the term Caucasian. I'm surprised that many ppl are not aware that the term Caucasian has supremacist roots. The term originated in the 1700s by a bunch of bros who believed the ppl in the "Caucus region" were the most beautiful ppl in the world, made in "God's image". sjsu.edu/people/carol.m…

Out of curiosity I attempted to book a COVID-19 test in Toronto today using the screening tool and followed ALL the links to the assessment centre sites at 7 pm. Shall we see what happened? Get your popcorn and Kleenex ready. covid19toronto.ca Women's college. Alarm set for tomorrow at 5:45 am. If I'm not successful, at least I will see the sunrise.

In my job as a doctor I handle risk assessment regularly. I am also a parent to two kids. My daughter has been sent home to quarantine due to a confirmed case of COVID-19 in her class. I have some concerns as it pertains to Covid containment in schools. 1/ @tdsb @TOPublicHealth High risk ppl (confirmed close contact w covid19) are in the SAME lineups as low risk ppl (runny nose).These lineups are LONG rn.If you don't believe me check out covidwaits.com. Social distancing is not always maintained. Glad these lines are mostly outdoors for now. 2/

As we may be headed into a long few months and bummed about everything-here is a thread of easy trails and gardens you can visit with kids around Toronto and vicinity for some nature therapy. We visited all of these: Williamson park ravine. Entrance on Gerrard east of Coxwell. Short half km walk but sweet. Smalls creek runs through it. Image

Review on sickle cell trait and covid outcomes in Black popl’n by @UofT resident Dr.Osundiji. So important for us to study genetics in non-whites to better understand health outcomes in these populations. There is a caveat tho. ncbi.nlm.nih.gov/pmc/articles/P… It is not a pass for the genetics community to ignore the well established non-genetic determinants of health outcomes in Black people. I’ll call this, “the other things”. blackhealthalliance.ca/home/social-de…

How can I make a decision re: my intentions when I have no guiding info, @tdsb? "To help with our planning, you will be receiving beginning Tue Aug 11 an automated School Messenger phone call from the TDSB asking for you to indicate your intentions for your child for Sept." I know nothing about final class sizes or how they're going to do lunches or if there is more outdoor time. I know nothing about what is the protocol if my kid gets a fever or someone gets COVID in my kid's school. I don't even know what the actual hours of school will be?!

This stock image of "difficult patient" is really amazing. As a physician of 15 years, I have yet to meet a patient with a face like that Image Appears here: depts.washington.edu/bhdept/ethics-…

The pandemic has really increased # of emails, and I'm so appreciative to those who use email well. I'm a big fan of the BLUF (Bottom Line Up Front) format to improve email communication. Seems like a good time to share a "how to" link, animalz.co/blog/bottom-li… If you're asking me to do something, please communicate this in the first few lines of the email. Do not bury it in the email. I will likely ignore your request otherwise. It is not because I don't care. I just have too many inboxes to maintain and too many distractions.

Afternoon ad hoc debate today in office about whether publicly funded genetics clinic resources should b used to see patients referred for interpretation of self-pay whole genome sequencing (in cases where there is no clin evidence to support use or they want to get test faster) In some cases depending on result the patient may get triaged faster in clinic (patient planning a pregnancy, result that has mgt implications). So wealthier people who could afford to self pay could jump the waiting list queue that currently stands at 1 yr in many gen clinics.
