This study examined the effect of the introduction of TAVR on overall AVR rates in the US using the STS and STS/ACC registries.  From 2008 to 2013, AVR rates increased at hospitals performing TAVR by 69%, including a 22% increase in surgical AVR; the latter increase was primarily in low- and moderate-risk patients.  In contrast, non-TAVR hospital AVR volume increased by 16%.  Overall survival rates improved during the period in both settings.

Program directors from 6 distinctly different training centers assessed educational costs for CT resident training.  Before formal accounting information was explored, the PDs estimated the annual cost per resident to be $250,000.  The actual costs per year per resident ranged from $330,000 to $667,000, with a mean of $483,000.  Faculty teaching costs made up more than half of the total costs, whereas simulation costs comprised 0 to $80,000.  The contributions of the residents to program savings averaged $37,000.

This study explored recent patterns of surveillance imaging 4-8 mos after surgical treatment of early stage lung cancer using the SEER database.  Initial imaging consisted of CXR (60%), CT (25%) and PET (3%).  13% of patients received no imaging.  NCCN guidelines adherence for receipt of CT was 47%, but increased from 28% to 60% over the period of study.  Adherence was reduced in pts with stage I disease and those who had surgery as a single treatment modality.

This study determined the relationship of pre-hospital use of epinephrine during resuscitation to survival in patients who experienced return of spontaneous circulation after out of hospital cardiac arrest. 73% received epinephrine, and 17% of those patients experienced a good outcome (discharged alive with good neurologic status).  Of those who did not received epinephrine, 63% had a good outcome.  There was a dose-response effect.  Delayed administration of epinephrine had the worst outcomes.

This is an interesting historical vignette describing the discovery of transfer factor (TLCO, DLCO) and its subsequent importance in pulmonary physiology and cardiorthoracic risk assessment.

This is an excellent article on the feasibility of offering Veno Arterial ECMO in outlying community hospitals for Refractory Cardiogenic Shock (RCS).  The Authors review a four year time period and describe assessing 104 patients of whom 87 were deemed eligible for V-A ECMO therapy. The authors conclude that providing V-A ECMO therapy in a community hospital environment for RCS is both feasible and resulted in an impressive mortality reduction of 30%.  The Authors present points regarding the need for a constantly available dedicated staff, strong logistical support, and dedicated ICU beds. In addition, the authors discuss the probability of increased costs and resource utilization.

A reexamination of data from the National Lung Screening Trial (NLST) with nodules above the 4mm, has been shown that increasing the nodule size threshold for a positive screen, substantially reduces the false-positive CT screenings rate and increase slightly the lung cancer missed or delayed but without affecting the survival.

141,905 isolated primary surgical aortic valve replacements (SAVR) were stratified by STS risk of mortality.   SAVR outcomes were superior to those by the predicted risk models.
