Ego4D: Around the World in 3,000 Hours of Egocentric Video.

We introduce Ego4D, a massive-scale egocentric video dataset and benchmark suite. It offers 3,670 hours of daily-life activity video spanning hundreds of scenarios (household, outdoor, workplace, leisure, etc.) captured by 931 unique camera wearers from 74 worldwide locations and 9 different countries.

Hyperacute adrenal insufficiency after hemorrhagic shock exists and is associated with poor outcomes.

Background: Adrenal insufficiency (AI) has been extensively described in sepsis but not in acute hemorrhage. We sought to determine the incidence of hyperacute AI (HAI) immediately after hemorrhage and its association with mortality.

Methods: Patients with acute traumatic hemorrhagic shock presenting to the R Adams Cowley Shock Trauma Center prospectively had serum cortisol levels collected on admission.

Evaluation of multidetector computed tomography for penetrating neck injury: a prospective multicenter study.

Background: The purpose of this prospective multicenter study was to evaluate a clinical protocol integrating multidetector computed tomographic angiography (MDCTA) as the initial screening examination for the work-up of penetrating neck injury.

Methods: All penetrating neck injuries assessed at two Level I trauma centers (January 2009-July 2011) prospectively underwent a structured clinical examination. Those with hard signs of injury (active bleed, instability, expanding/pulsatile hematoma, bruit/thrill, hemoptysis, hematemesis, and air bubbling) underwent exploration, those who were asymptomatic were observed.
