Sacubitril/valsartan preserves regional cardiac function following myocardial infarction in rats.

Aims: Sacubitril/valsartan (Sac/Val) is used for treatment of heart failure. The effect of Sac/Val on regional dysfunction following myocardial infarction (MI) remains uncertain. This study aimed at understanding the effects of Sac/Val on regional function after MI.

A 4D continuous representation of myocardial velocity fields from tissue phase mapping magnetic resonance imaging.

Myocardial velocities carry important diagnostic information in a range of cardiac diseases, and play an important role in diagnosing and grading left ventricular diastolic dysfunction. Tissue Phase Mapping (TPM) Magnetic Resonance Imaging (MRI) enables discrete sampling of the myocardium's underlying smooth and continuous velocity field. This paper presents a post-processing framework for constructing a spatially and temporally smooth and continuous representation of the myocardium's velocity field from TPM data.

Accelerated magnetic resonance imaging tissue phase mapping of the rat myocardium using compressed sensing with iterative soft-thresholding.

Introduction: Tissue Phase Mapping (TPM) MRI can accurately measure regional myocardial velocities and strain. The lengthy data acquisition, however, renders TPM prone to errors due to variations in physiological parameters, and reduces data yield and experimental throughput. The purpose of the present study is to examine the quality of functional measures (velocity and strain) obtained by highly undersampled TPM data using compressed sensing reconstruction in infarcted and non-infarcted rat hearts.

Barriers and strategies for oral medication adherence among children and adolescents with Type 2 diabetes.

Aims: Examine barriers for taking glucose-lowering oral medications, associated baseline characteristics, strategies used, and the adherence impact in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study.

Methods: We studied youth prescribed oral diabetes medications over two years (N = 611, 583, and 525 at 6, 12, and 24 months). Clinicians documented barriers (e.
