On September 25th, 2015, Doctor of Pharmacy Bernard Hsu[1][2] launched a YouTube channel Chubbyemu.[3] On October 6th, 2015, Chubbyemu[4] posted a Let's Play video of Nuclear Throne, the earliest video currently available on the channel (shown below).

In the following two years, the primary focus of the channel were gaming, motivation and fitness videos, including videos such as "Dark Souls 3 'US Prestige Edition' Unboxing with Yhorm the Giant Statue,"[5] "RELATIONSHIPS (are weird)"[6] and "FAT SHAMING RANT."[7]

On May 27th, 2017, Chubbyemu[8] uploaded the first video following his now-signature "X Did Y, This Is What Happened" formula titled "I Built This PC for $1360 in 2010. Here's How It Holds Up In 2017." The video received over 2.6 million views in three years. On August 7th, 2017, Chubbyemu[9] uploaded his first medical case analysis video titled "A Mom Drank 3 Gallons Water In 2 Hours. This is What Happened to Her Brain" (shown below).

What interests me here is the adherence to using the "Patient [Initials]" format for naming the individuals in these videos, because this is typically a practice reserved for case study subjects who are still alive for the sake of privacy. Despite this, the subjects of these videos are dead, meaning that it's perfectly legal and scientifically ethical to use the subjects' real names, and the "2 drops of mercury" individual even has her own Wikipedia article specifically focusing on the accident that killed her.

My best guess is that this is done out of courtesy for the departed and their friends & family and/or because it's still somewhat standard practice to use the "Patient [Initials]" formula if most scientific literature on the subject was published within their lifetime (e.g. Henry Molaison, a famed case study for the location and function of the memory circuits following an early, crude form of anti-epilepsy surgery that cut out much of his hippocampus & amygdala and the surrounding cortices, is still oftentimes referred to as Patient HM over a decade after his death in 2008).
