Wedge resection before lobectomy for patients with T1N0M0 non-small cell lung cancer: a propensity score matching analysis.

Background: Whether wedge resection of a tumor before lobectomy (Wed + Lob) can improve the prognosis of non-small cell lung cancer (NSCLC) has yet to be determined comprehensively. This study aimed to compare the effects of Wed + Lob with those of direct lobectomy (Lob) on survival and tumor cell dissemination in patients with T1N0M0 NSCLC.

Methods: A cohort of 813 patients with T1N0M0 NSCLC who underwent lobectomy at a single center in China was investigated.

Early extubation in operating room after single-lung transplantation: a single institutional experience.

Background: Early endotracheal extubation in operating room (E-OR) after lung transplantation is rarely reported worldwide. Herein, we aim to explore the feasibility and safety of E-OR after lung transplantation and demonstrate its potential benefits.

Methods: This study is a single-center retrospective database analysis of 18 patients.

Response to the combination use of pazopanib with olaratumab in a patient with lung-metastatic embryonal rhabdomyosarcoma: a case report.

Embryonal rhabdomyosarcoma (ERMS) is associated with a low prevalence, poor prognosis, and limited treatment efficacy. Here, we report a case of a 21-year-old male whose disease relapsed in the thoracic cavity following traditional chemotherapy. The patient received eight sequential cycles of traditional chemotherapy using a combination of the cyclophosphamide + vincristine + doxorubicin hydrochloride liposome (CAV) and etoposide + ifosfamide (IE) regimens.

Additional length model for the impedance end correction of microperforated panels.

An additional length model is usually used to describe the reactive part of the impedance end correction of microperforated panels, which is extended to describe the resistive part. The cross-sectional impedance is computed along the axis of one perforation cell with a circular hole. Except for the obvious jumps in the narrow regions at the inlet and outlet of the perforation, the impedance varies linearly along the axis following exactly that of the viscous wave in the circular hole.

Early removal of chest tubes leads to better short-term outcome after video-assisted thoracoscopic surgery lung resection.

Background: Currently, some studies have shown that early removal of a chest tube after video-assisted thoracoscopic surgery (VATS) lobectomy is safe and can shorten the length of hospital stay. The purpose of our study was to retrospectively analyze the association between early chest tube removal and hospital stay in patients who have undergone lobectomy.

Methods: This retrospective analysis included patients undergoing different types of lung resections including lobectomy and wedge resection.

Broadband low frequency sound absorption using a monostable acoustic metamaterial.

This Letter presents a monostable acoustic metamaterial that has the potential to implement broadband sound absorption in low frequencies. The proposed metamaterial is realized by placing a flexible panel with a magnetic proof mass in a symmetric magnetic field. A theoretical model of the metamaterial is established and experimentally validated.

Glasses-free 3D versus 2D video-assisted thoracoscopic thymectomy: a single-center short-term comparative study.

Background: Thymectomy is widely used to for the treatment of thymomas, thymic cysts, thymic adenocarcinomas, and other thymic diseases. The development of video-assisted thoracoscopic surgery (VATS) thymectomy by our team offers the advantages of a glasses-free 3D thoracoscopic system for pulmonary surgery. The aim of the present retrospective study was to compare the advantages and short-term outcomes of glasses-free 3D VATS .
