Background: Airway stenosis is a known complication of prolonged intubation in hospitalized patients. With the high rate intubations patients with COVID-19 pneumonia, laryngotracheal (LTS) that drastically reduces quality life for who may remain tracheostomy-dependent. Methods: Patient medical history, laryngoscopy, and CT imaging were obtained from records. Results: We report four cases compli...

  Abstract   Background: Recently, small dense low density lipoprotein (sdLDL) has been   highlighted as a new risk factor for the coronary artery disease (CAD).Small dense   LDLs are believed to be atherogenic since these particles are taken up more easily by   arterial wall. They are readily oxidized and have reduced affinity for low density   lipoprotein (LDL) receptor and increased affinity...
