Efficacy and safety of applying oxidized regenerated cellulose sheets to the parietal pleura of open chest wounds in thoracic surgery: a prospective randomized controlled trial protocol.

Background: According to a large-scale clinical trial in Japan, segmentectomy for small peripheral non-small cell lung cancer has an advantage over lobectomy in terms of overall survival, while it could also increase the incidence of local recurrence. In ipsilateral reoperations, intrathoracic adhesions from a previous surgery increase the risk of lung injury and bleeding, which may result in intraoperative and postoperative complications. The ability of oxidized regenerated cellulose (ORC) sheets to prevent postoperative adhesions has been demonstrated in the abdomen, and the same effect is expected in the thoracic region.

Loco-regional relapse pattern and timing after segmentectomy in patients with c-IA non-small cell lung cancer.

Background: Segmentectomy has been recognized as the standard procedure for small peripheral lung cancer; however, it has been shown that loco-regional relapse is more common with segmentectomy than with lobectomy. This study aims to investigate the long-term outcomes and loco-regional relapse patterns in patients with clinical stage IA (c-IA) non-small cell lung cancer (NSCLC) after segmentectomy and compare them with those after lobectomy.

Methods: We retrospectively compared the long-term outcomes of 115 patients who underwent segmentectomy for c-IA NSCLC with those of 292 patients who underwent lobectomy between January 2008 and December 2015.

Deep learning-based prediction of nodal metastasis in lung cancer using endobronchial ultrasound.

Objective: Endobronchial ultrasound-guided transbronchial needle aspiration is a vital tool for mediastinal and hilar lymph node staging in patients with lung cancer. Despite its high diagnostic performance and safety, it has a limited negative predictive value. Our objective was to evaluate the diagnostic performance of deep learning-based prediction of lung cancer lymph node metastases using convolutional neural networks developed from automatically extracted images of endobronchial ultrasound videos without supervision of the lymph node location.

Successful Treatment of Acute Eosinophilic Myocarditis due to Eosinophilic Granulomatosis with Polyangiitis in an Older Man, Followed by Dual Single Photon Emission Computed Tomography.

An 83-year-old man with a 5-month history of asthma presented to the emergency department with chest oppression and dyspnea. Electrocardiography showed ST-segment depression. Transthoracic echocardiography showed no asynergy with an ejection fraction of 62%.
