Core Components of Cardiac Rehabilitation Programs: 2024 Update: A Scientific Statement From the American Heart Association and the American Association of Cardiovascular and Pulmonary Rehabilitation: Endorsed by the American College of Cardiology.

The science of cardiac rehabilitation and the secondary prevention of cardiovascular disease has progressed substantially since the most recent American Heart Association and American Association of Cardiovascular and Pulmonary Rehabilitation update on the core components of cardiac rehabilitation and secondary prevention programs was published in 2007. In addition, the advent of new care models, including virtual and remote delivery of cardiac rehabilitation services, has expanded the ways that cardiac rehabilitation programs can reach patients. In this scientific statement, we update the scientific basis of the core components of patient assessment, nutritional counseling, weight management and body composition, cardiovascular disease and risk factor management, psychosocial management, aerobic exercise training, strength training, and physical activity counseling.

Enhancing single-cell transcriptomics using interposed anchor oligonucleotide sequences.

Single-cell transcriptomics, which utilises barcodes and unique molecular identifiers (UMIs) for polyA+ mRNA capture, is compromised by oligonucleotide synthesis errors. To address this, we modified the oligonucleotide capture design and integrated an interposed anchor between the barcode and the UMI. This design significantly reduces the need to discard reads due to synthesis inaccuracies.

Dietary Inflammatory Score and Incident Heart Failure in the Reasons for Geographic and Racial Differences in Stroke (REGARDS) Study.

Background: Inflammation plays a key role in the development of heart failure (HF), and diet is a known modifiable factor that modulates systemic inflammation. The dietary inflammatory score (DIS) is a tool to quantify the inflammatory components of diet. We sought to determine whether the DIS is associated with incident HF events.

Conceptualizing and Measuring Systemic Racism.

This article provides a guide for rigorous, theory-driven measurement approaches, proposing best practices for the scientific study of systemic racism in health research. We argue that the analytical crux of measuring systemic racism-a complex, interconnected, and dynamic system-lies in operationalizing the collective logics, properties, and mechanisms that undergird racial inequities. Misalignment between measurement tools and these foundational features undermines research validity, as incongruent measures distort findings and obscure systemic racism's true impacts.

Prehospital critical care beyond advanced life support for out-of-hospital cardiac arrest: A systematic review.

Aim: To assess the clinical outcomes of patients with out-of-hospital cardiac arrest attended by prehospital critical care teams compared to non-critical care teams.

Methods: This review was prospectively registered with PROSPERO and the eligibility criteria followed a PICOST framework for ILCOR systematic reviews. Prehospital critical care was defined as any provider with enhanced clinical competencies beyond standard advanced life support algorithms and dedicated dispatch to critically ill patients.
