Background: The risk-benefit ratio of the Absorb bioresorbable vascular scaffold (BVS) may vary before and after 3 years, the time point of complete bioresorption of the poly-L-lactic acid scaffold.

Objectives: The aim of this study was to determine the time-varying outcomes of the Absorb BVS compared with cobalt-chromium everolimus-eluting stents (EES) from a large individual-patient-data pooled analysis of randomized trials.

Methods: The individual patient data from 5 trials that randomized 5,988 patients undergoing percutaneous coronary intervention to the Absorb BVS vs EES with 5-year follow-up were pooled.

Background: Hypertension management is a national priority. However, hypertension control rates are suboptimal and vary across clinics, even among those in the same health system and geographic region.

Objective: To identify organizational barriers and facilitators that impact hypertension management at the provider, clinic, and health system level.

The brain is an exceptionally lipid-rich organ with a very complex lipid composition. Lipids are central in several neuronal processes, including membrane formation and fusion, myelin packing, and lipid-mediated signal transmission. Lipid diversity is associated with the evolution of higher cognitive abilities in primates, is affected by neuronal activity, and is instrumental for synaptic plasticity, illustrating that lipids are not static components of synaptic membranes.

Article Synopsis
  • Researchers are investigating how resonant dark matter can convert into low-frequency radio waves in Earth's ionosphere, particularly in the mass range of about 10^{-9} to 10^{-8} eV.
  • The typical methods for calculating this conversion are inadequate due to the nonrelativistic nature of dark matter, so a new approach involving a second-order boundary-value problem is applied.
  • Using a small dipole antenna to detect these radio waves could increase sensitivity to dark photon and axionlike particle dark matter, offering a new avenue for exploring uncharted regions of dark matter physics.
