Efficacy and Safety of SGLT2 Inhibitors in Heart Failure: Observational Evidence in Geriatric Patients AGING-HF.

Background: Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have shown beneficial effects in heart failure (HF) management, but data on their use in geriatric populations with high comorbidity remain limited. This observational study aimed to assess the real-world efficacy and safety of SGLT2i in elderly patients with HF.

Methods: This prospective multicenter study included 496 patients hospitalized for acute heart failure across 3 geriatric units.

Contribution of the Low-Density Lipoprotein Receptor Family to Breast Cancer Progression.

The low-density lipoprotein receptor (LDLR) family comprises 14 single-transmembrane receptors sharing structural homology and common repeats. These receptors specifically recognize and internalize various extracellular ligands either alone or complexed with membrane-spanning co-receptors that are then sorted for lysosomal degradation or cell-surface recovery. As multifunctional endocytic receptors, some LDLR members from the core family were first considered as potential tumor suppressors due to their clearance activity against extracellular matrix-degrading enzymes.
