Purpose: The profession of genetic counselors has existed for over 50 years. This article provides an update on the global state of the genetic counseling (GC) profession in 2022 and 2023.

Methods: We used a survey approach to collect data from individuals who were identified as being leaders in GC practice and/or education around the world.

Background: Late gadolinium-enhanced (LGE) MRI has become a widely used technique to non-invasively image the left atrium prior to catheter ablation. However, LGE-MRI images are prone to variable image quality, with quality metrics that do not necessarily correlate to the image's diagnostic quality. In this study, we aimed to define consistent clinically relevant metrics for image and diagnostic quality in 3D LGE-MRI images of the left atrium, have multiple observers assess LGE-MRI image quality to identify key features that measure quality and intra/inter-observer variabilities, and train and test a CNN to assess image quality automatically.

Annually, 30 million children are affected by newborn conditions, most in low-income countries, with long-term implications for survivors. We aimed to evaluate neonatal intracranial pathologies identifiable on cranial ultrasound (CUS) in sub-Saharan Africa (SSA). This systematic review and meta-analysis explored the spectrum of neonatal intracranial pathology, in nine databases, using the Joanna Briggs Institute Systematic Review Tools.

Background: Contractile, electrical, and structural remodeling has been associated with atrial fibrillation (AF), but the progression of functional and structural changes as AF sustains has not been previously evaluated serially.

Objectives: Using a rapid-paced persistent AF canine model, the authors aimed to evaluate the structural and functional changes serially as AF progresses.

Methods: Serial electrophysiological studies in a chronic rapid-paced canine model (n = 19) prior to AF sustaining and repeated at 1, 3, and 6 months of sustained AF were conducted to measure changes in atrial conduction speed and direction.
