Predictors of Peripheral Retinal Non-Perfusion in Clinically Significant Diabetic Macular Edema.

Diabetic macular edema (DME) is a significant cause of vision loss. The development of peripheral non-perfusion (PNP) might be associated with the natural course, severity, and treatment of DME. The present study seeks to understand the predictive power of central macular changes and clinico-demographic features for PNP in patients with clinically significant DME.

Fully Automated Assessment of Cardiac Chamber Volumes and Myocardial Mass on Non-Contrast Chest CT with a Deep Learning Model: Validation Against Cardiac MR.

: To validate the automated quantification of cardiac chamber volumes and myocardial mass on non-contrast chest CT using cardiac MR (CMR) as a reference. : We retrospectively included 53 consecutive patients who received non-contrast chest CT and CMR within three weeks. A deep learning model created cardiac segmentations on axial soft-tissue reconstructions from CT, covering all four cardiac chambers and the left ventricular myocardium.

Global organelle profiling reveals subcellular localization and remodeling at proteome scale.

Defining the subcellular distribution of all human proteins and their remodeling across cellular states remains a central goal in cell biology. Here, we present a high-resolution strategy to map subcellular organization using organelle immunocapture coupled to mass spectrometry. We apply this workflow to a cell-wide collection of membranous and membraneless compartments.

Developing and validating an intervention-specific knowledge assessment for person-centered communication in nursing home continuing education.

Purpose: The assessment of knowledge gain from educational interventions is a common practice in dementia care research. This study aimed to refine and validate the Changing Talk Scale (CHATS), a tool for assessing knowledge of effective and person-centered communication in nursing home staff. CHATS was integrated into the Changing Talk: Online (CHATO) education program to measure the knowledge gains resulting from it.

Personalized perioperative blood pressure management in patients having major non-cardiac surgery: A bicentric pilot randomized trial.

Study Objective: We hypothesize that personalized perioperative blood pressure management maintaining intraoperative mean arterial pressure (MAP) above the preoperative mean nighttime MAP reduces perfusion-related organ injury compared to maintaining intraoperative MAP above 65 mmHg in patients having major non-cardiac surgery. Before testing this hypothesis in a large-scale trial, we performed this bicentric pilot trial to determine a) if performing preoperative automated nighttime blood pressure monitoring to calculate personalized intraoperative MAP targets is feasible; b) in what proportion of patients the preoperative mean nighttime MAP clinically meaningfully differs from a MAP of 65 mmHg; and c) if maintaining intraoperative MAP above the preoperative mean nighttime MAP is feasible in patients having major non-cardiac surgery.

Design: Bicentric pilot randomized trial.
