Background: Cognitive therapy for PTSD (CT-PTSD) is an efficacious treatment for children and adolescents with post-traumatic stress disorder (PTSD) following single incident trauma, but there is a lack of evidence relating to this approach for youth with PTSD following exposure to multiple traumatic experiences.

Aims: To assess the safety, acceptability and feasibility of CT-PTSD for youth following multiple trauma, and obtain a preliminary estimate of its pre-post effect size.

Method: Nine children and adolescents (aged 8-17 years) with multiple-trauma PTSD were recruited to a case series of CT-PTSD.

Background: The identification of predictors of treatment response is crucial for improving treatment outcome for children with anxiety disorders. Machine learning methods provide opportunities to identify combinations of factors that contribute to risk prediction models.

Methods: A machine learning approach was applied to predict anxiety disorder remission in a large sample of 2114 anxious youth (5-18 years).

Hemophagocytic lymphohistiocytosis is a rare life-threatening condition, with a high mortality rate, characterized by a dysfunctional immune response resulting in multi-organ damage. The secondary or sporadic form of the disease can be triggered by a multitude of infections, malignancies, and autoimmune disorders. Tuberculosis is commonly involved as a trigger for hemophagocytic lymphohistiocytosis.

Background: This study examined the power of theory-derived models to account for the development of PTSD, Complex PTSD (CPTSD), depression, and anxiety in children and adolescents who had experienced a single-event trauma.

Methods: Children ( = 234, aged 8-17 years) recruited from local Emergency Departments were assessed at two and nine weeks post-trauma. Data obtained from self-report questionnaires completed by the child, telephone interviews with parents, and hospital data were used to develop four predictive models of risk factors for PTSD, CPTSD, depression, and Generalized Anxiety Disorder (GAD).

Background And Purpose: Obstructive sleep apnea is associated with increased dementia risk. Nocturnal hypoxemia, which can be more severe during rapid eye movement (REM) sleep, may be a key mechanism. This study examines how REM hypoxemia affects memory and explores whether hippocampal vulnerability to hypoxemia mediates this effect in older adults at risk for dementia.
