Increased Association With Malnutrition and Malnourishment in Older Adults Admitted With Hip Fractures Who Have Cognitive Impairment and Delirium, as Assessed by 4AT.

Background: The Royal College of Physicians recently introduced the 4AT (Alertness, Abbreviated Mental Test-4, Attention, and Acute change or fluctuating course) for screening cognitive impairment and delirium. Here, we examined the association of the 4AT with nutrition status in patients admitted to a hospital with hip fractures between January 1, 2016, and June 6, 2019.

Methods: Nutrition status was assessed using the Malnutrition Universal Screening Tool, and the 4AT was assessed within 1 day after hip surgery.

Delayed onset of malignant hyperthermia induced by isoflurane and desflurane compared with halothane in susceptible swine.

Background: Desflurane (difluoromethyl 1-fluoro 2,2,2-trifluoroethyl ether) is a new inhalational anesthetic currently under investigation for use in humans. Recently, the authors showed that desflurane is a trigger of malignant hyperthermia (MH) in susceptible swine. To date, there has been no in vivo comparison of the relative ability of inhalational anesthetics to trigger MH.
