An Observational Study of Evidence-Based Therapies in Older Patients with Heart Failure with Reduced Ejection Fraction: Insights from a Dedicated Heart Failure Clinic.

Despite significant advances in the management of heart failure with reduced ejection fraction (HFrEF), data concerning older patients remain limited. The purpose of this study was to evaluate the implementation of guideline-directed medical therapy (GDMT) in older patients with HFrEF along with cardiac events and variation in clinical and echocardiographic parameters during follow-up in a heart failure (HF) clinic. We conducted a retrospective observational analysis of patients with HFrEF aged ≥ 80 years who attended an HF clinic between March 2022 and February 2023.

Extracellular Vesicles: A Novel Diagnostic Tool and Potential Therapeutic Approach for Equine Osteoarthritis.

Osteoarthritis (OA) is a chronic progressive degenerative joint disease that affects a significant portion of the equine population and humans worldwide. Current treatment options for equine OA are limited and incompletely curative. Horses provide an excellent large-animal model for studying human OA.

Breast cancer and cardiovascular health.

Modern cancer therapies greatly improve clinical outcomes for both early and advanced breast cancer patients. However, these advances have raised concerns about potential short- and long-term toxicities, including cardiovascular toxicities. Therefore, understanding the common risk factors and underlying pathophysiological mechanisms contributing to cardiovascular toxicity is essential to ensure best breast cancer outcomes.

Controlling particle size of levan in powder form with different technologies.

Levan is a fructose polysaccharide with multiple applications in different fields, but its obtaining in powdered form with a narrow particle size distribution is a complicated task. Two techniques, electrospraying and supercritical antisolvent (SAS) precipitation, were used to process levan that was first obtained enzymatically. The SAS process was able to micronize the polymer (at experimental conditions far above the mixture critical point of the solvent-antisolvent system) to obtain spherical particles between 0.
