Epidemiology, Ventilation Management, and Outcomes in Invasively Ventilated Coronavirus Disease 2019 Patients: An Analysis of Four Observational Studies in Four Countries on Two Continents.

Epidemiology, ventilator management, and outcomes in patients with acute respiratory distress syndrome (ARDS) because of coronavirus disease 2019 (COVID-19) have been described extensively but have never been compared between countries. We performed an individual patient data analysis of four observational studies to compare epidemiology, ventilator management, and outcomes. We used propensity score weighting to control for confounding factors.

Background: Nonweightbearing preoperative assessments avoid quadriceps contraction that tends to affect patellar motion and appear to be inaccurate in quantifying anatomic factors, which can lead to incorrect corrections and postoperative complications.
Questions/purposes: (1) Does the relationship of patellar axial malalignment and other anatomic factors change during weightbearing? (2) What anatomic factor was most strongly correlated with recurrent patellar dislocation during weightbearing?
Methods: This prospective, comparative, observational study recruited participants at our institution between January 2023 and September 2023. During this time, all patients with recurrent patellar dislocations received both weightbearing and nonweightbearing CT scans; control patients who received unilateral CT scans because of injuries or benign tumors received both weightbearing and nonweightbearing CT scans.
Purpose: Undifferentiated pleomorphic sarcomas (UPSs) demonstrate therapy-induced hemosiderin deposition, granulation tissue formation, fibrosis, and calcification. We aimed to determine the treatment-assessment value of morphologic tumoral hemorrhage patterns and first- and high-order radiomic features extracted from contrast-enhanced susceptibility-weighted imaging (CE-SWI).
Materials And Methods: This retrospective institutional review board-authorized study included 33 patients with extremity UPS with magnetic resonance imaging and resection performed from February 2021 to May 2023.
Influence of Insertion/Deletion Polymorphism of the Angiotensin Converting Enzyme Gene on Adiposity and Cardiac Function in Patients with Heart Failure.

Background: The angiotensin-converting enzyme (ACE) insertion/deletion (I/D) polymorphism (rs4340) is associated with the pathogenesis of heart failure (HF). This polymorphism may contribute to a greater propensity for severe HF and excess weight.
Objective: To evaluate adiposity, cardiac function, and their association with ACE I/D polymorphism in HF patients.
Clinical Evaluation of 3D Motion-Correction Via Scout Accelerated Motion Estimation and Reduction Framework Versus Conventional T1-Weighted MRI at 1.5 T in Brain Imaging.

From the Department of Neuroradiology, University Medical Center Mainz, Johannes Gutenberg University, Mainz, Germany (L.S.L., K.H.H., A.K., M.A.B., S.A., A.E.O.); Institute of Medical Biostatistics, Epidemiology, and Informatics, University Medical Center Mainz, Johannes Gutenberg University, Mainz, Germany (R.H.P.); and Siemens Healthineers AG, Forchheim, Germany (D.P., D.N.S.).
Objectives: The aim of this study was to investigate the occurrence of motion artifacts and image quality of brain magnetic resonance imaging (MRI) T1-weighted imaging applying 3D motion correction via the Scout Accelerated Motion Estimation and Reduction (SAMER) framework compared with conventional T1-weighted imaging at 1.5 T.
Materials And Methods: A preliminary study involving 14 healthy volunteers assessed the impact of the SAMER framework on induced motion during 3 T MRI scans.
