Radiogenomic features are predictive of anaplastic lymphoma kinase (ALK) rearrangement in surgically resected non-small cell lung cancer (NSCLC). ⋯ ALK-rearranged lung cancer has characteristic clinical and imaging features compared with EGFR mutant or WT/WT cohorts. Our findings suggest that young age, lobulated margin, solid lesion, and hypoattenuation at contrast-enhanced CT scan are important predictors of ALK-rearranged lung cancer.

Randomized Controlled Trial
Effect of a Single Bolus of Erythropoietin on Renoprotection in Patients Undergoing Thoracic Aortic Surgery With Moderate Hypothermic Circulatory Arrest.
Acute kidney injury (AKI) is associated with high morbidity and mortality. Recombinant human erythropoietin has been shown to exert cytoprotection against ischemia. This study examined the effect of erythropoietin in preventing AKI during thoracic aortic surgery with moderate hypothermic circulatory arrest. ⋯ A single bolus administration of erythropoietin 500 IU·kg(-1) at anesthesia induction failed to provide renoprotection in patients who underwent thoracic aortic surgery with moderate hypothermic circulatory arrest. However, erythropoietin significantly reduced cardiac complications, and lowered the incidence of prolonged vasopressor dependence.

Randomized Controlled Trial
A Randomized Controlled Trial of High-Flow Nasal Oxygen (Optiflow) as Part of an Enhanced Recovery Program After Lung Resection Surgery.
Patients undergoing thoracic surgery are at risk of postoperative pulmonary complications, which are associated with increased morbidity and mortality. High-flow nasal oxygen therapy delivers humidified, warmed positive airway pressure but has not been tested routinely after thoracic surgery. ⋯ Prophylactic high-flow nasal oxygen therapy, when incorporated into an enhanced recovery program, did not improve 6-minute walk test results but was associated with reduced length of hospital stay and improved satisfaction after lung resection, compared with standard oxygen. This finding has implications for reduced costs and better service provision, and a multicenter trial powered for length of stay is required.

Transcatheter aortic valves may develop structural valve deterioration. With that development the issue arises of repeated transcatheter aortic valve insertion. There are, unfortunately, limited data about repeated transapical valve insertion, with only a single case report in the literature. We report an additional successful case.

In the conventional ascending replacement for acute type A aortic dissection, the distal aortic anastomosis is frequently performed at the dissected site, and postoperative residual dissection in the arch and downstream aorta still occurs in most patients. We used open placement of a fenestrated stent graft during this operation. ⋯ An open fenestrated stent graft placement provided extensive primary repair of the thoracic aorta and a strong distal aortic stump during the conventional ascending aorta replacement for acute type A aortic dissection but did not increase the risk or technical difficulty of the operation.
