Observational StudyGait speed is a preoperative indicator of postoperative events after elective proximal aortic surgery.
The study objective was to evaluate whether 5-m gait speed, an established marker of frailty, is associated with postoperative events after elective proximal aortic surgery. ⋯ Slow gait speed is a preoperative indicator of risk for postoperative events after elective proximal aortic surgery. Gait speed may be an important tool to complement existing operative risk models, and its application may identify patients who may benefit from presurgical and postsurgical rehabilitation.

Quantifying invasiveness of clinical stage IA lung adenocarcinoma with computed tomography texture features.
The study objectives were to establish and validate a nomogram for pathological invasiveness prediction in clinical stage IA lung adenocarcinoma and to help identify those potentially unsuitable for sublobar resection-based computed tomography texture features. ⋯ We established and validated a nomogram to compute the probability of invasiveness of clinical stage IA lung adenocarcinoma with great calibration, which may contribute to decisions related to resection extent.

Longitudinal analysis of National Institutes of Health funding for academic thoracic surgeons.
National Institutes of Health (NIH) funding for academic (noncardiac) thoracic surgeons at the top-140 NIH-funded institutes in the United States was assessed. We hypothesized that thoracic surgeons have difficulty in obtaining NIH funding in a difficult funding climate. ⋯ Contrary to our hypothesis, thoracic surgeons have received more NIH funding over time. Thoracic surgeons are able to fill the roles of modern surgeon-scientists by obtaining NIH funding during an era of increasing clinical demands. The NIH should continue to support this mission.

Respiratory strength and pectoralis muscle mass as measures of sarcopenia: Relation to outcomes in resected non-small cell lung cancer.
Physical biomarkers to stratify patients with lung cancer into subtypes predictive of outcome beyond tumor-related characteristics are underexplored. This study was designed to investigate the clinical utility of preoperative sarcopenia based on respiratory strength and pectoralis muscle mass to predict the risk of death. ⋯ Preoperative sarcopenia as identified by the criteria of low respiratory strength and reduced pectoralis muscle mass is significantly associated with poor overall survival. This may help to develop more individualized management strategies and optimize longitudinal care for patients.

Outcomes after surgical ventricular restoration for ischemic cardiomyopathy.
The study objective was to evaluate the short- and long-term outcomes of patients with ischemic cardiomyopathy after surgical ventricular restoration and to identify risk factors related to poor results. ⋯ Patients with ischemic dilative cardiomyopathy have favorable short- and long-term outcomes after ventricular restoration. Age, preoperative ejection fraction less than 25%, inadequate left ventricular surgical reverse remodeling, and type of surgical technique negatively affect long-term survival.
