The neuronal mechanisms underlying propofol-induced modulation of consciousness are poorly understood. Neuroimaging studies suggest a potential role for non-specific thalamic nuclei in propofol-induced loss of consciousness. We investigated the contribution of the paraventricular thalamus (PVT), a midline thalamic nucleus that has been implicated in arousal control and general anaesthesia with inhaled anaesthetics, to loss and recovery of consciousness during propofol anaesthesia. ⋯ The paraventricular thalamus contributes to the control of consciousness transitions in propofol anaesthesia in mice. This provides a potential neuroanatomical target for controlling consciousness to reduce anaesthetic dose requirements and side effects.

Editorial Comment
Clinical hypnosis: implications in anaesthesia and perioperative care.
A randomised trial published in the British Journal of Anaesthesia describes hypnosis compared with general anaesthesia in 60 children undergoing superficial surgery. We describe a definition of clinical hypnosis; the goals and conduct of hypnotic communication; and its potential as both an adjunct and, in suitable cases, alternative to traditional pharmacological anaesthesia.

Review Meta Analysis
Sleep quality as a mediator of the relation between depression and chronic pain: a systematic review and meta-analysis.
Chronic pain and depression represent two global health problems with considerable economic consequences. Although existing literature reports on the relation between depression and pain conditions, meta-analytic evidence backing the mediating role of sleep disturbance as one of the main symptoms of depression is scarce. To examine the extent to which sleep disturbance mediates the depression-chronic pain association, we conducted a systematic review and meta-analysis of the associations of chronic pain, depression, and sleep quality. ⋯ PROSPERO CRD42022338201.
