    Background: Delirium prevention requires optimal management of pain and anxiety. Given the limitations of current pharmacologic interventions, evaluation of novel non-pharmacological interventions is required. Virtual reality (VR) stimulation may be a promising intervention because of its capability to reduce psychophysiological stress, pain, and anxiety and to restore cognitive and attentional capacities. Objective: To ascertain patients' and providers' perceptions of acceptability and safety of VR intervention in the intensive care unit (ICU). Methods: We enrolled a cohort of 15 ICU patients and 21 health care providers to administer a 15-minute session showing a relaxing beach scene with VR headsets and nature sound effects. Participants were then asked to rate their experiences on a Likert scale survey. Results: The majority of patients (86%, 12 of 14) rated the headsets as moderately to very comfortable. All had moderate or greater sense of presence in the virtual environment, and 79% (11 of 14) rated their overall experience at 3 or greater (5 indicating that they enjoyed it very much). Seventy-one percent (10 of 14) of the patients felt that their anxiety was better with VR, and 57% (8 of 14) did not notice a change in their pain or discomfort. All health care providers found the headset to be at least moderately comfortable and felt a moderate or greater sense of presence. All providers concluded that VR therapy should be available for their patients. Both groups experienced minimal side effects. Conclusion: In this prospective study of perceptions of VR therapy for ICU patients and health care providers, there was a high level of acceptance, with minimal side effects, for both groups despite their low levels of prior experience with virtual reality and video gaming.

    Mycobacterium mucogenicum meningitis due to external ventricular drain
    (Microbiology, 2020-09-03) Moiz, Salwa; Rahman, Omar; Morcos, Mark; Siddiqui, Asma; Bin Hameed, Usman; Medicine, School of Medicine
    Introduction: Mycobacterium mucogenicum is a rare non-tuberculous organism associated with catheter-related infections when pathogenic in humans. We present the first case of an external ventricular drain (EVD)-associated M. mucogenicum meningitis. Case presentation: A 55-year-old woman had EVD placement for obstructive hydrocephalus following traumatic subarachnoid haemorrhage. Cerebrospinal fluid (CSF) was obtained 5 days later for fever and neurological changes. M. mucogenicum was ultimately isolated from the CSF and the patient was placed on appropriate antibiotics. Her management included replacement of the EVD and a prolonged course of anti-mycobacterial antibiotics. CSF findings showed her response to therapy and neurological exam improved after 6 weeks. Conclusion: M. mucogenicum infections are very rare and existing reports indicate that it may be a device- or catheter-related pathogen. This microorganism has not been previously associated with an EVD. Ours may be the first documented report of EVD-related M. mucogenicum infection.
