Occupational therapist-guided cognitive interventions in critically ill patients: a feasibility randomized controlled trial.

Purpose: Intensive care unit (ICU) delirium is a common complication of critical illness requiring a multimodal approach to management. We assessed the feasibility of a novel occupational therapist (OT)-guided cognitive intervention protocol, titrated according to sedation level, in critically ill patients.

Methods: Patients aged ≥ 18 yr admitted to a medical/surgical ICU were randomized to the standard delirium prevention protocol or to the OT-guided cognitive intervention protocol in addition to standard of care.

Effect of early cognitive interventions on delirium in critically ill patients: a systematic review.

Purpose: A systematic review of the literature was conducted to determine the effects of early cognitive interventions on delirium outcomes in critically ill patients.

Source: Search strategies were developed for MEDLINE, EMBASE, Joanna Briggs Institute, Cochrane, Scopus, and CINAHL databases. Eligible studies described the application of early cognitive interventions for delirium prevention or treatment within any intensive care setting.

A reflected energy prediction model for long-range hydroacoustic reflection in the oceans.

Acoustic energy from underwater earthquakes and explosions can propagate over long distances with very little attenuation in the deep ocean. When this sound encounters a seamount, island, or continental margin, it can scatter and again propagate over long distances. Hydrophones in the deep sound channel can detect these reflections tens of minutes or hours after arrivals from the direct source-to-receiver path.
