John Toftegaard week 7

 This week I spent more time working on my research project. Our device went through several revisions after further consultation and realizations that getting the device to stay in place would be more difficult than expected. I also began running fluid flow simulations mimicking the heart environment in order to determine how the device will react to and influence the blood flow once in position. 

I also spent more time shadowing in the catheter lab. I got to witness another TAVR procedure. This time however they interventionist used a different brand heart valve. This valve requires a balloon dilation before the placement of the valve and was designed to meet the needs of the larger patient. After the unique prep they deployed the valve similar to how any other valve is used. It was interesting to see how every company has their own specification when they design valves, and how each variation can fit different patients batter than others. Especially when designing devices this has made me realize how patient specific you need to be.

Jenny Deng Week 1: Acclimating to a medical teaching hospital

Image
Me, Faith, Julia, and India met Dr. Jason Spector on the first day. He was welcoming and enthusiastic to have us shadow him and work in his lab. We met Sophia and Dr. Xue Dong from his research side and Dr. Jaime Bernstein and Dr. Ann Ni on the surgical side. The next day, we were invited to see a case Dr. Spector was in. This would be my first time in the operating room. For this particular case, a radial forearm flap was being utilized to reconstruct part of a tongue that was partially resected due to oral carcinoma. The ENT team were operating near the head and the plastic surgery team by the arm. It was less bloody than anticipated. A large Zeiss microscope was rolled into the OR for the microsurgery portion that required joining the donor and recipient site blood supply. The following day, we saw multiple other surgeries: a melanoma on the scalp required exposing the area in preparation for a second surgery with a graft. Everyone was excited about doing the surgery, and Dr. Specto

Cory Knox - Dr. Liston - Week 1

 After settling into our dorms at Lasdon, we were greeted by Carly and Kelly with a warm welcome and orientation to the hospital. The environment was fast paced and exciting - paired with seeing everyone in their business attire and enjoying a bagel breakfast, it was a fun way to start the week. We also had the opportunity to meet Dr. Min and Dr. Sabuncu, who shared with us their professional stories, and of course recommendations for things to do in the city. It was especially exciting to hear about Dr. Min's career and how he became the Chair of Radiology, as a person of color and someone who takes exciting risks that have led to his success today.  I was also able to meet with Dr. Liston's lab this week through one-on-ones and attending their weekly lab meeting. Dr. Liston's lab pairs psychiatry and neuroscience to characterize TMS (transcranial magnetic stimulation) as a treatment for patients with major depressive disorder (MDD). Their research spans neurophysiological

Anna Hazelwood/Dr. Evelyn Horn - Week 1

6/3/24 - 6/7/24 Week 1: This week began with a great introduction to what our summer plans will look like. It was great to meet Carly Skudin and Dr. Kelly Gillen at the start of the week and check in with our fellow classmates to see that everyone arrived safely. After this meeting on Monday, we were able to get our IDs, after which I headed over to my mentor Dr. Evelyn Horn's office on the 4th floor of the Starr pavilion to discuss the plans for the summer. We discussed that she has clinic days on Tuesdays and Thursdays, but that many of the other doctors also see patients during the other days of the week. I was also able to shadow a clinic visit with cardiologist Dr. Udhay Krishnan to end the day.  Tuesday morning we had a great morning meeting where we were able to meet Dr. Min and Dr. Sabuncu, as well as Dr. Wang virtually. They gave us great insight for what to expect this summer. The remainder of the week consisted of many clinic visits where I observed cardiologists Dr. Hor
