People with heart failure can safely drink fluids without restrictions

A large-scale study found that limiting fluid intake in patients with stable heart failure has no health benefits and may even cause increased thirst. Conversely, drinking more fluids without restriction did not lead to any negative outcomes, suggesting that fluid restrictions are unnecessary for these patients.

Minimally invasive valve repair reduces heart failure hospitalizations in patients with severe tricuspid regurgitation

A minimally invasive procedure using a clip to repair the tricuspid valve significantly reduced symptom severity and decreased recurrent hospitalization for heart failure. The study found a 28% reduction in hospitalizations at two years, with improved safety and effectiveness compared to medical therapy alone.

Conformal radiation-type programmable metasurface for agile millimeter-wave OAM generation

Researchers developed a conformal programmable metasurface that generates Orbital Angular Momentum (OAM) waves at millimeter-wave frequencies without external spatial excitation. The design mitigates feed leakage radiation and realizes low-profile configuration, enabling next-generation wireless communication and space-based applications.
