Objective: We examined trainees in surgery and internal medicine who received National Institutes of Health (NIH) F32 postdoctoral awards to determine their success rates in obtaining future NIH funding.
Background: Trainees participate in dedicated research years during residency (surgery) and fellowship (internal medicine). They can obtain an NIH F32 grant to fund their research time and have structured mentorship.
Background: Current ex vivo lung perfusion (EVLP) protocols aim to achieve perfusion flows of 40% of cardiac output or more. We hypothesized that a lower target flow rate during EVLP would improve graft function and decrease inflammation of donation after circulatory death (DCD) lungs.
Methods: A porcine DCD and EVLP model was utilized.
Objective: To determine trends in National Institutes of Health (NIH) funding for cardiac surgeons, hypothesizing they are at a disadvantage in obtaining funding owing to intensive clinical demands.
Methods: Cardiac surgeons (adult/congenital) currently at the top 141 NIH-funded institutions were identified using institutional websites. The NIH funding history for each cardiac surgeon was queried using the NIH Research Portfolio Online Reporting Tools Expenditures and Results (RePORTER).
In the not too distant past, illegible handwriting was considered to be the biggest problem with medical record keeping. Now the primary problem with medical records is that they are disorganized, and usually undigested, data dumps. A solution to at least part of this problem lies in utilizing the principles of the problem-oriented record.

Summary Background Data: Advances in ECPR have decreased mortality after cardiac arrest; however, subsequent IRI contributes to late multisystem organ failure. Attenuation of IRI has been reported with the use of an A2AR agonist.
Over our combined nearly 50 years as surgical educators, we have been asked many times by medical students how they should prepare for and function in a Surgery Clerkship. It is still easy for me (C.G.

The initial version of this treatise was written as I (Curt Tribble) was learning to do coronary anastomoses over 30 years ago, and I worried that I was not being taught very well how to go about doing them. It seemed to me that my teachers were channeling Dr. Alain Carpentier, who often answered questions about his mitral valve repair techniques by saying, "Oh, you just know.

Using an established porcine DCD model, we sought to determine the effect of increasing warm ischemia time (WIT) after circulatory arrest on lung function during ex vivo lung perfusion (EVLP).
Methods: Porcine donors (n = 15) underwent hypoxic cardiac arrest, followed by 60, 90, or 120 minutes of WIT before procurement and 4 hours of normothermic EVLP.

There are three major transitions in the educational trajectory of those heading into a career in surgery. The first transition is from the first year or two of medical school to the clerkships of the third year. The second is the transition from medical school into the first postgraduate year of residency training.

The utility of career development grants (K awards) for achieving the goal of R01 funding remains debated, particularly for surgeon-scientists. We examined the success rate for cardiothoracic and vascular (CTV) surgeons compared with other specialties in converting K-level grants into R01 equivalents.

Utilizing donation after circulatory death (DCD) donors may help to address the supply-demand mismatch. The objective of this study is to determine the potential donor pool expansion with increased procurement of DCD organs from patients who die at hospitals.

Kirschstein Institutional National Research Service Award (T32) provides institutions with financial support to prepare trainees for careers in academic medicine. In 1990, the Cardiac Surgery Branch of the National Heart, Lung and Blood Institute (NHLBI) was replaced by T32 training grants, which became crucial sources of funding for cardiothoracic (CT) surgical research.

Realizing that the education and training of medical students and surgical residents would require knowledge, skills, and understanding above and beyond the usual training of a resident in surgery, I (CT) started an informal, though enriching, attempt to find those on the grounds of the University who might share ideas and insights that could enhance the educational programs in the Department. This process embodied the vision of the founders of the University to create an "academical village.

Background: Sepsis is the leading cause of lung injury in adults and can lead to acute respiratory distress syndrome (ARDS). Using a novel technique of isolated in vivo lung perfusion (IVLP), we hypothesized that normothermic IVLP will improve oxygenation and compliance in a porcine model of sepsis-induced lung injury.
Methods: Mature adult swine (n = 8) were administered lipopolysaccharide (LPS; 50 μg/kg over 2 hours) via the external jugular vein, followed by sternotomy and central extracorporeal membrane oxygenation (ECMO) cannulation (right atrium to ascending aorta).
There is a considerable amount of data that using more than one arterial graft provides a survival advantage for patients undergoing coronary bypass operations. The Society of Thoracic Surgeons has a set of official guidelines for the use of arterial grafts which include the following recommendations:Internal mammary arteries (IMA's) should be used to bypass the left anterior descending (LAD) artery when bypass of the LAD is indicated.As an adjunct to left internal mammary artery (LIMA), a second arterial graft (right IMA or radial artery [RA]) should be considered in appropriate patients.

We have performed 121 lung transplants with a median sternotomy incision from 2013-2017. We present our technique for lung transplantation utilizing cardiopulmonary bypass with a median sternotomy, and discuss the potential advantages of this technique.
View Article and Find Full Text PDFObjective: The current supply of acceptable donor lungs is not sufficient for the number of patients awaiting transplantation. We hypothesized that ex vivo lung perfusion (EVLP) with targeted drug therapy would allow successful rehabilitation and transplantation of donation after circulatory death lungs exposed to 2 hours of warm ischemia.
Methods: Donor porcine lungs were procured after 2 hours of warm ischemia postcardiac arrest and subjected to 4 hours of cold preservation or EVLP.
Background: Sepsis is the number one cause of lung injury in adults. Ex vivo lung perfusion (EVLP) is gaining clinical acceptance for donor lung evaluation and rehabilitation and may expand the use of marginal organs for transplantation. We hypothesized that 4 hours of normothermic EVLP would improve compliance and oxygenation in a porcine model of sepsis-induced lung injury.

Our objective was to assess the influence of resident experience to understand the learning curve for CABG.
Methods: From 2008 to 2014, all isolated on-pump CABG (n = 1,668) during which a resident performed the entire operation (including sternotomy, mammary artery harvest, coronary anastomoses, and closure) were reviewed.
Massive pulmonary embolism (PE) is associated with significant morbidity and mortality. Treatment for massive PE can include systemic thrombolysis and catheter-directed therapy. We present the case of a patient with massive PE successfully treated with catheter-directed therapy, using extracorporeal membrane oxygenation for hemodynamic support, and discuss some of the potential complications associated with this therapy.

Everyone who has flown on a plane will recall that the flight attendants always tell passengers that, if oxygen is needed, one must put one's own mask on first, before helping others put their masks on. And the obvious reason for that admonition is that you cannot help others if you, yourself, are impaired.

Objective: Critical organ shortages have resulted in ex vivo lung perfusion gaining clinical acceptance for lung evaluation and rehabilitation to expand the use of donation after circulatory death organs for lung transplantation. We hypothesized that an innovative use of airway pressure release ventilation during ex vivo lung perfusion improves lung function after transplantation.
Methods: Two groups (n = 4 animals/group) of porcine donation after circulatory death donor lungs were procured after hypoxic cardiac arrest and a 2-hour period of warm ischemia, followed by a 4-hour period of ex vivo lung perfusion rehabilitation with standard conventional volume-based ventilation or pressure-based airway pressure release ventilation.
