CT-based machine learning radiomics predicts Ki-67 expression level and its relationship with overall survival in resectable pancreatic ductal adenocarcinoma.

Department of Hepato-Biliary-Pancreatic Surgery, Huadong Hospital affiliated to Fudan University, Shanghai, China.
Background: The prognostic prediction of pancreatic ductal adenocarcinoma (PDAC) remains challenging. This study aimed to develop a radiomics model to predict Ki-67 expression status in PDAC patients using radiomics features from dual-phase enhanced CT, and integrated clinical characteristics to create a radiomics-clinical nomogram for prognostic prediction.
Methods: In this retrospective study, data were collected from 124 PDAC patients treated surgically at a single center, from January 2017 to March 2023.
Successful extracorporeal membrane oxygenation for heart failure after adolescent idiopathic scoliosis surgery.

Department of Orthopedic, MacKay Memorial Hospital, No. 92, Sec. 2, Zhongshan N. Rd, Taipei, Taiwan.
Purpose: Spine surgery, particularly deformity correction, is associated with a high risk of peri-operative or post-operative complications, and these complications can lead to catastrophic consequences. This case report will present the etiology and treatment process of the peri-operative cardiac arrest during scoliosis correction surgery.
Method: In this report, we present a case of cardiac arrest during posterior correction surgery in a 17-year-old female patient with adolescent idiopathic scoliosis.
The Role of Fetal Echocardiography in Predicting Postnatal Pulmonary Venous Obstruction in Neonates with TAPVR: A Single Center Experience.

Division of Pediatric Cardiology, UT Southwestern, Children's Medical Center, Dallas, TX, USA.
Total anomalous pulmonary venous return (TAPVR) is a high risk and rare cardiac malformation with a low prenatal detection rate and predicting obstruction in these cases is difficult. We sought to investigate fetal echocardiographic parameters associated with postnatal pulmonary venous obstruction (PPVO). We performed a retrospective review of 26 patients with TAPVR who had a fetal echocardiogram from 2010 to 2021.

Department of Otolaryngology, Fengdu County People's Hospital, Fengdu County, Chongqing, China.
Objective: This study aims to analyze anatomical parameters of the transmission route of sigmoid sinus tinnitus (SST) to explore its mechanism and speculate on possible responsible anatomical abnormalities.
Methods: Clinical data were retrospectively collected from SST and sigmoid sinus wall dehiscence (SSWD) patients suggested by temporal bone high resolution computed tomography (HRCT), with and without tinnitus, at the First Affiliated Hospital of Chongqing Medical University from January 2015 to August 2022. Patients were divided into SSWD tinnitus ( = 61), and non-tinnitus ( = 60) groups based on HRCT features.
Optical coherence tomography-enabled classification of the human venoatrial junction.

Columbia University, Department of Electrical Engineering, New York, United States.
Significance: Radiofrequency ablation to treat atrial fibrillation (AF) involves isolating the pulmonary vein from the left atria to prevent AF from occurring. However, creating ablation lesions within the pulmonary veins can cause adverse complications.
Aim: We propose automated classification algorithms to classify optical coherence tomography (OCT) volumes of human venoatrial junctions.
