Background: The Modified Inflation-Deflation Method (MIDM) is widely used in China in pulmonary segmentectomies. We optimized the procedure, which was named as Blood Flow Blocking Method (BFBM), also known as "No-Waiting Segmentectomy". This method has produced commendable clinical outcomes in segmentectomies.

Background: In the traditional computed tomography (CT) simulation process, patients need to undergo CT scans before and after injection of iodine-based contrast agent, resulting in a cumbersome workflow and additional imaging dose. Contrast-enhanced spectral CT can synthesize true contrast-enhanced (TCE) images and virtual noncontrast (VNC) images in a single scan without geometric misalignment. To improve work efficiency and reduce patients' imaging dose, we studied the feasibility of using VNC images for radiotherapy treatment planning, with true noncontrast (TNC) images as references and explored its dosimetric advantages compared to using TCE images.

Laboratory of Image Science and Technology, Key Laboratory of New Generation Artificial Intelligence Technology and Its Interdisciplinary Applications, Ministry of Education, Southeast University, Sipailou 2, Nanjing, P.R. China.
Purpose: The segmentation of target volume and organs at risk (OAR) was a significant part of radiotherapy. Specifically, determining the location and scale of the esophagus in simulated computed tomography images was difficult and time-consuming primarily due to its complex structure and low contrast with the surrounding tissues. In this study, an Enhanced Cross-stage-attention U-Net was proposed to solve the segmentation problem for the esophageal gross tumor volume (GTV) and clinical tumor volume (CTV) in CT images.

Background: Elective ventilation and paralysis have been shown to decrease the anastomosis-related complications following primary repair of esophageal atresia (EA). Repeated endotracheal tube (ETT) block and replacement can increase these complications. We evaluated the results of our strategy of electively changing the ETT just before shifting the patient to the postoperative ward for elective ventilation.

Article Synopsis
- Infective endocarditis (IE) is a serious condition with high mortality rates, especially in patients with abnormal heart valves like bicuspid aortic valves (BAV).
- A 22-year-old female initially hospitalized for splenic infarction was later diagnosed with IE after presenting symptoms of acute toe ischemia and showing vegetations on her aortic valve.
- The case highlights the importance of early detection and treatment of IE, especially in young patients, emphasizing the need to avoid anti-coagulation to prevent complications like embolic events.
