Healthcare staff well-being and use of support services during COVID-19: a UK perspective.

Background: The COVID-19 pandemic has drastically increased demands on healthcare workers (HCWs) leaving them vulnerable to acute psychological distress, burnout and post-traumatic stress. In response, supportive services in a central London hospital mobilised mental health support specifically for HCWs.

Aims: This rapid evaluation assessed HCW psychological welfare during the acute phase of the COVID-19 pandemic and their use of supportive services made available.

Beyond the K-hole: a 3-year longitudinal investigation of the cognitive and subjective effects of ketamine in recreational users who have substantially reduced their use of the drug.

Rationale: Ketamine is a dissociative anaesthetic that is also a drug of abuse. Previous studies have demonstrated persisting episodic and semantic memory impairments in recreational ketamine users 3 days after taking ketamine. However, the degree to which these deficits might be reversible upon reduction or cessation of ketamine use was not known.
