Background And Objectives: Childhood risk factors are associated with cardiovascular events in adulthood. We compared the utility of a risk model based solely on nonlaboratory risk factors in adolescence versus a model that additionally included lipids to predict cardiovascular events in adulthood.

Methods: The study comprised 11 550 participants from 7 longitudinal cohort studies in the United States, Australia, and Finland with risk factor measurements in adolescence and followed into adulthood.

Membrane external-cavity surface-emitting lasers (MECSELs) represent a cutting-edge approach in pushing the performance boundaries of vertically emitting semiconductor lasers. The fundamental concept of employing an extremely thin gain membrane, spanning from hundreds of nanometers to a few micrometers in thickness and sandwiched between transparent heat spreaders, introduces novel opportunities through uniform double-sided optical pumping and enhanced heat dissipation from the active region. Additionally, these advantages of MECSELs facilitate more intricate band gap engineering possibilities for the active region by integrating multiple types of quantum wells (QWs) into a single laser gain structure.

Article Synopsis
  • * Early intermittent feeding of mice on a high-cholesterol diet speeds up atherosclerosis by altering arterial macrophage behavior and gene expression associated with ASCVD.
  • * The Young Finns Study links early cholesterol exposure to increased carotid atherosclerotic plaque in adulthood, emphasizing the need for better hyperlipidaemia management early in life to prevent ASCVD.
