Does the adult thymus have a purpose and function? Are there any long-term health effects of thymectomy? Tune in to another Swedish Thoracic surgery journal review where we discuss the recent paper out of the NEJM which reports on the health consequences of thymus removal in adults. This paper has been widely picked up by the media and our patients frequently bring it into the office. Listen as we discuss the study population, methods, and potential applications of this paper.

Learning Objectives:

- Review the purpose and function of the thymus.
- Discuss the population, methods, and results of this trial.
- Discuss the application of this paper and how it may or may not impact clinical practice for thoracic surgeons.

Did you know that 13% of trauma patients who go home with an opioid prescription will develop opioid dependence?  Multimodal pain regimens not only reduce opioid consumption, but also improve pain control.  On this episode of the BIG T TRAUMA series, we explore a multimodal approach to pain management...and tackle some surgical dogma along the way.

A 70 year old healthy female is referred to you with a 5.7 cm abdominal aortic aneurysm. As an astute clinician you are aware that current guidelines support surgical repair for her AAA. What if there was new data to suggest this patient may not benefit from repair? What would be the optimal size threshold that she would benefit from AAA repair? Tune into this episode of Behind the Knife, where the vascular surgery subspecialty team discusses a paper that challenges current size threshold guidelines for AAA repair. 

Hosts: 
Dr. Bobby Beaulieu is an Assistant Professor of Vascular Surgery at the University of Michigan and the Program Director of the Integrated Vascular Surgery Residency Program as well as the Vascular Surgery Fellowship Program at the University of Michigan.

Dr. Frank Davis is an Assistant Professor of Vascular Surgery at the University of Michigan

Dr. Drew Braet is a PGY-5 Integrated Vascular Surgery Resident at the University of Michigan

Learning Objectives
- Review the current size threshold guidelines for surgical repair of abdominal aortic aneurysms

- Understand the limitations of the aforementioned guidelines

- Understand the methodology, findings, limitations, and clinical applications of the manuscript “Size thresholds for repair of abdominal aortic aneurysms warrant reconsideration.”

Take a listen into the wild and fascinating world of lung transplantation! One of the biggest challenges for any transplant is organ preservation to provide the best possible recovery and outcome for recipients. That’s especially important for lung transplant, which remains one of the most complex and challenging areas in the field of transplantation. This episode takes a deep dive into the lung transplant landscape and discusses new technologies and innovations that are revolutionizing the field. Jon Williams is joined by Dr. Elliot Wakeam, MD, a thoracic surgeon and lung transplant expert from University of Toronto to discuss the advent of ex-vivo lung perfusion (EVLP) systems and how that and other preservation techniques may impact the future of lung transplantation. Also, Dr. Wakeam provides unique perspectives as faculty from one of the best lung transplant programs in the world.

As we move towards a model of Competency-Based Surgical Education, individualization of training may be needed. How can we get the right education to the right trainee at the right time? How can we link education to actual patient outcomes? Precision education aims to do just that, while leveraging technology, data, and analytics to decrease burden on assessors. While this approach offers a lot of promise to advance surgical education, it can be difficult to conceptualize how this would be implemented in practice. We’re joined by an expert in the field of precision medical education, Dr. Jesse Burk-Rafel, to break down what precision education is and how it might integrate into our current system of surgical education


Join hosts Nicole Brooks MD, Judith French PhD, and Jeremy Lipman MD, MHPE for this exciting conversation with Jesse Burk-Rafel MD.


Learning Objectives


1.     Listeners will define precision education.
2.     Listeners will describe examples of how precision medical or surgical education is being used currently. 
3.     Listeners will explain barriers that must be addressed with the implementation of precision surgical education, including bias and issues with data sharing. 
4.     Listeners will consider how precision surgical education will evolve, including possible use within their own institution to completement competency-based surgical education.

In this Journal Review episode, the Hernia Content Team from Carolinas Medical Center reviews the definition and meaning of a hernia center. In a subspecialty field that is in its relative infancy, the specialization of care at hernia centers is a relatively new concept. The team reviews two relevant publications on hernia centers that help to provide guidance on this topic for the hernia community.
