Quantitative Dual‐Energy CT Perfusion Versus SPECT/CT V/Q Scintigraphy for Preoperative Lung Function Assessment: A Prospective Cohort Study

open access: yesJournal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction Accurate preoperative physiological assessment is critical for high‐risk patients undergoing lung resection to predict postoperative lung function. This study compared quantitative dual‐energy CT (DECT) perfusion with SPECT/CT for lobar perfusion mapping in an at‐risk oncological cohort.

Network Structure and the Efficiency Gains from Mergers: Evidence from U.S. Freight Railroads

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT The trade‐off between market power and efficiency gains is central to antitrust analyses of mergers, but empirical evidence quantifying efficiencies remains limited. Using transaction‐level data from U.S. freight railroads (1985–2005), this article quantifies merger‐induced cost efficiencies, driven mainly by eliminating inter‐railroad ...

Pulmonary artery catheters or central venous catheters for cardiac surgery: the PUMA Pilot randomised clinical trial

open access: yesAnaesthesia, EarlyView.
Summary Introduction Pulmonary artery catheters are used widely in cardiac surgery despite observed associations with worse outcomes and guidelines that recommend against their routine use. No adequately powered randomised trials are available. Methods The PUMA Pilot was a multicentre, randomised, parallel assignment, open‐label, pilot and feasibility ...

Depth and Procedure Specific Effects of Antimicrobial Versus Conventional Sutures on Surgical Site Infection: A Systematic Review and Meta‐Analysis

open access: yesANZ Journal of Surgery, EarlyView.
Antimicrobial sutures may be particularly beneficial in colorectal and abdominal procedures, where reductions in deep SSI may offset the additional suture cost. Several studies also reported favorable wound‐healing outcomes. ABSTRACT Background Surgical site infections (SSIs) are common postoperative complications that delay wound healing and increase ...

Identification of Autologous Tissue Sources and Optimization of a Treatment Method for Intraoperative Manufacturing of Heart Valve Constructs

open access: yesArtificial Organs, EarlyView.
The use of autologous connective tissue, such as pericardium or peritoneum, combined with controlled tissue treatment, has the potential to result in a more durable heart valve prosthesis than current commercial prostheses. ABSTRACT Introduction Valvular heart disease remains a leading cause of morbidity and mortality. Current biological and mechanical
