This scoping review synthesized all interventions that tested either the prevention or improvement of mental health for adolescents living with HIV. It provides valuable insights into improving the mental health of HIV-infected adolescents and can guide further research and practice in this area.

This paper provides the protocol for a pilot trial that will investigate the feasibility, acceptability, fidelity, and preliminary efficacy of a combined youth-friendly suicide prevention and problem-solving intervention in reducing suicidal ideation and behaviors in adolescents living with HIV (ALWH) in Malawi.

This study shows evidence that temporally resolved and functionally contextualized structural basis sets can accurately reflect dynamic functional processes and capture diagnostically relevant structure-functional coupling while detecting nuanced functionally driven structural components that cannot be captured with traditionally computed structural bases. Differential analysis of component stability across repeated scans from...

This study suggest that reduced pyramidal cell excitability is present at baseline in future CHR-Converters, supporting the hypothesis that hypofunction of pyramidal cells is a primary pathology in schizophrenia, rather than a consequence of chronic illness. Positive symptoms among CHR-Converters may reflect compensatory downregulation of inhibition.

This study reveals small but consistent associations between negative symptom dimensions and predominantly prefrontal region cortical thickness, and limbic region volumes. These findings advance our understanding of the network of anatomical regions that may contribute to the severity of negative symptoms in schizophrenia.

Children as young as 5 years old may experience thoughts about suicide, but these behaviors are not well understood. This study involved 98 children 5 to 10 years of age, recruited for potential adversity exposure, and their caregivers, who answered questions about suicidal thoughts and behaviors (STBs) during an in-home...
