Association of CT characteristics of osteosarcoma lung metastases with spontaneous pneumothorax: a retrospective analysis.
J Thorac Dis
December 2024
Department of Radiology, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.
Background: Spontaneous pneumothorax (SP) has been reported to be associated with osteosarcoma lung metastases, but the computed tomography (CT) characteristics of lung metastases in patients with pneumothorax have not been comprehensively described. The study aimed to describe the CT characteristics of lung metastases in patients with osteosarcoma and to identify factors associated with SP.
Methods: This study comprised 123 patients diagnosed with osteosarcoma lung metastasis at our hospital between January 2016 and December 2021.
Au-Functionalized Metal-Organic Framework Coordinated Nanotherapeutics for Substrate Self-Supplied Parallel Catalytic and Calcium-Overload-Mediated Therapy of Cancer.

Collaborative Innovation Center of Tumor Marker Detection Technology, Equipment and Diagnosis Therapy Integration in Universities of Shandong, Shandong Province Key Laboratory of Detection Technology for Tumor Makers, College of Medicine, Linyi University, Linyi 276005, China.
The multiple enzymatic properties of the Au-modified metal-organic framework (Au-MOFs) have made it a functional catalytic system for antitumor treatment. However, in the face of insufficient catalytic substrates in tumor tissue, it is still impossible to achieve efficient treatment of tumors. Herein, Au-MOFs loaded with hyaluronic acid (HA)-modified calcium peroxide nanoparticles (CaO NPs) were used to construct a nanozyme (Au-MOF/CaO/HA) for substrate self-supplied and parallel catalytic/calcium-overload-mediated therapy of cancer.

Division of Pulmonary Medicine, Department of Internal Medicine, Keio University School of Medicine.
Background: Coronary artery calcification (CAC) detected through chest computed tomography (CT) strongly predicts cardiovascular events in asymptomatic individuals undergoing primary prevention. Few studies with limited sample sizes have investigated the predictive value of CAC for cardiovascular complications in COVID-19. This study examined the impact of CAC on cardiovascular complications using a large-scale COVID-19 database.

Department of Oral and Maxillofacial Radiology, Peking University School and Hospital of Stomatology & National Center of Stomatology & National Clinical Research Center for Oral Diseases & National Engineering Research Center of Oral Biomaterials and Digital Medical Devices, Beijing, China; Research Unit of Precision Pathologic Diagnosis in Tumors of the Oral and Maxillofacial Regions, Chinese Academy of Medical Sciences, Beijing, China. Electronic address:
Objective: To establish a submandibular gland imaging reporting and data system (SI-RADS) and explore its value in diagnosing submandibular gland (SMG) tumors.
Study Design: Patients with primary SMG tumors who underwent enhanced computed tomography (CT) scanning and surgical intervention at Peking University Hospital of Stomatology (2013-2022) were retrospectively included. The imaging data were assessed for acquisition of the relevant imaging features, including lesion boundary, shape, enhancement, calcification, lymph node, and adjacent tissue involvement, and vascular invasion.
The diagnostic dilemma of adrenal vascular tumors: analysis of 21 cases and systematic review of the literature.
Endocrine
January 2025
Anatomic Pathology - Department of Medical and Surgical Sciences (DIMEC), University of Bologna, Bologna, Italy.
Purpose: Adrenal vascular tumors are mainly represented by adrenal cavernous hemangiomas (ACHs) and adrenal cystic lymphangiomas (ACLs). Their radiological features often overlap with malignant tumors, therefore ruling out malignancy becomes mandatory. We analyzed clinical, radiological, and histopathological data to identify specific characteristics of these tumors.
