Comparison of Underlying Risk of Developing and Dying from Lung Cancer in Screened Populations.

Background: Trial participants are typically healthier than the general population. Differences in underlying characteristics between the population undergoing lung cancer screening (LCS) and LCS trial participants may alter the benefits of LCS.

Research Question: Does the risk of developing and dying from lung cancer differ between trial participants and the general population?

Study Design And Methods: Using data from the i) North Carolina Lung Screening Registry (NCLSR), ii) 2022 Center for Disease Control and Prevention's Behavioral Risk Factor Surveillance System (BRFSS) Lung Cancer Screening Module, and iii) National Lung Screening Trial (NLST), we estimated the 5-year probability of developing and dying from lung cancer if not screened using publicly available macros.

Evaluating diagnostic consistency: intra and interobserver agreement in rotator cuff tear classification using ultrasound videos.

Objective: Ultrasound (US) is a more accessible alternative to MRI for rotator cuff tear (RCT) assessment. Rapid US can identify RCTs, but accurate US interpretation remains challenging, even for experts. We performed a retrospective cross-sectional study to evaluate intraobserver and interobserver agreement and accuracy in RCT detection with US between expert and non-expert readers.

The United States' Early Experience With Lung Cancer Screening-Creation of a National Data Linkage: A Brief Report.

Introduction: Lung cancer screening has been recommended by the United States Preventive Services Taskforce since 2013. The Centers for Medicare and Medicaid Services coverage decision in early 2015 required data submission to a Centers for Medicare and Medicaid Services-approved registry for facilities to receive payment for screening. Only the American College of Radiology's Lung Cancer Screening Registry (LCSR) received approval for this purpose.

Management of Adult Condylar and Subcondylar Mandibular Fractures in a Level 1 Trauma Center.

Management of mandibular condylar and subcondylar fractures is heavily debated due to the proximity of important structures and complication risks. This study reviews the outcomes of 4 different treatment approaches: conservative, closed reduction with maxillomandibular fixation, open reduction and internal fixation, and open reduction and internal fixation with maxillomandibular fixation. A retrospective chart review of all patients with a facial fracture seen at a level one trauma center between 2012 and 2022 was performed.

Direct Imaging of Asymmetric Interfaces and Electrostatic Potentials inside a Hafnia-Zirconia Ferroelectric Nanocapacitor.

In hafnia-based thin-film ferroelectric devices, chemical phenomena during growth and processing, such as oxygen vacancy formation and interfacial reactions, appear to strongly affect device performance. However, the correlation between the structure, chemistry, and electrical potentials at the nanoscale in these devices is not fully known, making it difficult to understand their influence on device properties. Here, we directly image the composition and electrostatic potential with nanometer resolution in the cross section of a nanocrystalline W/HfZrO (HZO)/W ferroelectric capacitor using multimodal electron microscopy.
