Development of a cardiac surgery simulation curriculum: from needs assessment results to practical implementation.
A paradigm shift in surgical training has led to national efforts to incorporate simulation-based learning into cardiothoracic residency programs. Our goal was to determine the feasibility of developing a cardiac surgery simulation curriculum using the formal steps of curriculum development. ⋯ It is feasible to develop and implement a cardiac surgery simulation curriculum using a structured approach. High-fidelity, low-technology tools such as a fresh tissue cadaver laboratory and a virtual operating room could be important adjuncts.

Effect of changes in postoperative spirometry on survival after lung transplantation.
The decline in normalized forced 1-second expiratory volume after lung transplantation is inevitable; however, the effect of this change on survival is unknown. Additionally, the benefit of double versus single lung transplant is debated, particularly because pulmonary function is only slightly better after double lung transplant. Our goal was to determine the effect of the temporal pattern of post-transplant forced 1-second expiratory volume (percentage of predicted) on the risk of death after transplant and the differences in the sensitivity of single and double lung transplant to this relationship. ⋯ The results of our study have demonstrated the effect of changing lung function after lung transplantation on survival. Survival after single lung transplant proved more sensitive to declining pulmonary function, demonstrating an advantage of the increased pulmonary reserve provided by double lung transplant.

Pulmonary reperfusion injury after the unifocalization procedure for tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collateral arteries.
The aims of our study are to describe the incidence, clinical profile, and risk factors for pulmonary reperfusion injury after the unifocalization procedure for tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collateral arteries. We hypothesized the following: (1) Pulmonary reperfusion injury is more likely to occur after unifocalization procedures in which a septated circulation is not achieved, (2) pulmonary reperfusion injury is directly related to the severity of stenosis in major aortopulmonary collateral arteries, and (3) pulmonary reperfusion injury leads to longer intubation time and longer hospitalization. ⋯ Pulmonary reperfusion injury is common after the unifocalization procedure for tetralogy of Fallot/pulmonary atresia/major aortopulmonary collateral arteries. Severity of stenosis and bilateral unifocalization are associated with the development of reperfusion injury.

Association of feeding modality with interstage mortality after single-ventricle palliation.
Interstage mortality has been reported in 10% to 25% of hospital survivors after single-ventricle palliation. The purpose of this study was to examine the impact of feeding modality at discharge after single-ventricle palliation on interstage mortality. ⋯ Neonates undergoing single-ventricle palliation who require gastrostomy tube ± Nissen are at an increased risk of interstage mortality. The need for gastrostomy tube ± Nissen in this population may be a marker for other unmeasured comorbidities that place them at an increased risk of interstage mortality. Discharge with nasogastric feeds does not increase the risk of interstage mortality.

Development of The American Association for Thoracic Surgery guidelines for low-dose computed tomography scans to screen for lung cancer in North America: recommendations of The American Association for Thoracic Surgery Task Force for Lung Cancer Screening and Surveillance.
The study objective was to establish The American Association for Thoracic Surgery (AATS) lung cancer screening guidelines for clinical practice. ⋯ Annual lung cancer screening and surveillance with low-dose computed tomography is recommended for smokers and former smokers with a 30 pack-year history of smoking and long-term lung cancer survivors aged 55 to 79 years. Screening may begin at age 50 years with a 20 pack-year history of smoking and additional comorbidity that produces a cumulative risk of developing lung cancer of 5% or greater over the following 5 years. Screening should be undertaken with a subspecialty qualified interdisciplinary team. Patient risk calculator application and intersociety engagement will provide data needed to refine future lung cancer screening guidelines.
