Dosimetry and Toxicity Comparison of Three-Dimensional Conformal Radiation Therapy and Intensity-Modulated Radiation Therapy in Locally Advanced Lung Cancer Across a Large Statewide Quality Collaborative.

Department of Radiation Oncology, University of Michigan, Ann Arbor, MI. Electronic address:
Purpose/objective(s): Use of intensity-modulated radiation therapy (IMRT) versus three-dimensional conformal external beam radiation therapy (3D-CRT) for definitive chemoradiation therapy (CRT) in locally advanced non-small cell lung cancer (LA-NSCLC) has been associated with decreased late pneumonitis, decreased high dose to the heart (itself associated with improved overall survival), and improved patient quality of life. In a statewide radiation oncology quality consortium, we sought to evaluate the impact of IMRT versus 3D-CRT treatment technique on dosimetry and toxicity.
Materials/methods: From 2012 to 2022, 1746 LA-NSCLC patients meeting inclusion criteria underwent definitive RT (90% CRT) with either 3D-CRT (n=313) or IMRT (n=1433) and were enrolled in the [quality consortium] prospective, multicenter statewide initiative.
Evaluation of multiple ventricular septal defects using three-dimensional reconstruction models.

Department of Pediatrics, University of Toyama, Graduate School of Medicine, Toyama, Japan.
Objectives: Although there has been rapid development in the field of three-dimensional morphological analyses of congenital heart disease, with the three-dimensional volume-rendered images providing visualization of the external vascular anatomy, the precise reproduction of "Swiss-cheese" ventricular septum is not well established. We created three-dimensional printed models and computer graphics based on multi-slice computed tomography of patients with complex multiple ventricular septal defects for surgical decision planning of this difficult cardiac defect.
Methods: Seven patients with complex multiple ventricular septal defects were evaluated preoperatively using three-dimensional printed models and computer graphics to plan therapeutic interventions.
[Mortality in patients with ST-segment elevation myocardial infarction in Germany : Comparison of routine data vs. quality assurance vs. registry].

Medizinische Klinik B, Klinikum Ludwigshafen, Ludwigshafen, Deutschland.
The recording of mortality after acute myocardial infarction can be based on different data, some of which yield very different results. These differences are due to a number of factors, including the definition of acute myocardial infarction, patient selection and the methods used to determine mortality. While routine data are primarily used for billing purposes, procedural data for coronary angiography and percutaneous coronary intervention (PCI) are used for external quality assurance and therefore only include patients who undergo invasive diagnostic procedures.

The anatomic and radiographic characteristics of the pediatric proximal femur, including the presence of an active growth plate, an immature femoral calcar, greater trabecular density and plasticity and a relatively immature blood supply are very different from those of the adult proximal femur. Treatment protocols for PFNFs must differ from those for adult femoral neck fractures.

Rush University Medical Center, Chicago, Illinois, USA.
Background: Medial patellofemoral ligament reconstruction is frequently indicated for recurrent lateral patellar instability. The preoperative presence and severity of a J-sign have been associated with poorer postoperative outcomes.
Purpose: To determine the underlying anatomic factors that contribute to the presence, severity, and jumping quality of the J-sign.
