Background: Prevalence of posttraumatic stress disorder (PTSD) in refugees is reportedly higher in comparison to the general population. Refugee children specifically are often coping with trauma and loss and are at risk for mental health difficulties. With staggering numbers of people seeking refuge around the world and 50% being 18 years or younger, research examining the effects of trauma-focused therapies for refugee children with PTSD is highly needed.

Background

In the past twodecades,subanaestheticdosesofketaminehave been demonstrated to have rapid and sustained antidepressant effects, and accumulating research has demonstrated ketamine’s therapeutic effects for a range of psychiatric conditions.

Aims

In light of these findings surrounding ketamine’s psychotherapeutic potential, we systematically review the extant evidence on ketamine’s effects in treating mental health disorders.

Method

Understanding the neurobiological and cognitive processes underlying the development of posttraumatic stress disorder (PTSD) and its specific symptoms may facilitate preventive intervention development. Severe traumatic stress and resulting biological stress system activations can alter contextual memory processes. This may provide a neurobiological explanation for the occurrence of intrusive memories following trauma.

Background
Many healthcare workers do not seek help, despite their enormous stress and greater risk for anxiety, depression and post-traumatic stress disorder (PTSD).

Aims
This study screened for psychopathology and evaluated the efficacy of a brief, social contact-based video intervention in increasing treatment-seeking intentions among healthcare workers (trial registration: NCT04497415). We anticipated finding high rates of psychopathology and greater treatment-seeking intentions post-intervention.
