Iribarne and colleagues analyzed US Medicare claims from 2009 to 2014 to characterize bilateral internal mammary artery (BIMA) usage in coronary artery bypass surgery. They found that regional usage of BIMA differed significantly, and that BIMA usage was related to the intensity of cardiovascular care but only somewhat to surgical volume.

This study encompasses 2,363 pediatric patients who underwent cardiac surgery before and after the implementation of an acuity adaptable care model. Under the conventional model, patients moved among units and care teams based on age, operative status, and acuity. Under the acuity adaptable care model, patients remained in the Cardiac Care Unit and received care from one clinical team throughout their hospitalization. The acuity adaptable care model was associated with a lower failure-to-rescue rate and favorable trends for operative mortality and length of stay.

LoMauro and colleagues measured tidal volume and ribcage expansion during rest and exercise to evaluate functional recovery after minimally invasive thoracic surgery. Video-assisted thoracoscopic surgery (VATS) preserved these kinematic measures better than posterolateral thoracotomy, and the advantage was observed over two postoperative months. Patients compensated for restriction by shifting the expansion to the contralateral thorax after VATS and to the abdomen after thoracotomy.

Bhagat and colleagues analyzed the rate of unplanned hospital readmission from 2012 to 2015 using the American College of Surgeons National Surgical Quality Improvement Program Participant Use File. Thoracoscopic surgery was associated with a higher rate of postdischarge complications, a finding related to the shorter length of stay for these patients. Open surgery was associated with a higher rate of related unplanned readmissions, but after risk adjustment, open and thoracoscopic surgery readmissions were not different.

Sato and colleagues applied elliptic Fourier analysis to morphological aortic measurements from 80 patients with uncomplicated type B aortic dissection. The patients were divided in two groups according to aortic enlargement during follow-up. The shape of the aortic diameter at initial operation was a significant predictor of further morphologic development.

Newspaper and prime time TV advertisements are beginning in the US today that detail the medical toll that smoking exacts on its victims. The ads are paid for by big tobacco based on a court order from 2006 that has finally survived the appeal process. A spokesperson for one of the companies stated that they hope to "develop less risky tobacco products." The ads emphasize that smoking causes nearly 500,000 deaths annually in the US.
