Effort-based decision-making in ultra-high-risk for psychosis and bipolar disorder.

Background: Effort-based decision-making has been proposed as a potential mechanism contributing to transdiagnostic motivational deficits in psychotic disorder and bipolar disorder. However, very limited information is available about deficits in effort-cost-decision-making in the early stages of psychotic disorder and no study has investigated effort allocation deficits before the onset of bipolar disorder. Our aim was to investigate effort-based-decision-making in ultra-high-risk for psychosis (UHR-P) and bipolar disorder (UHR-BD).

Safety of Atypical Antipsychotics in a Child and Adolescent Inpatient Setting: A Naturalistic Study.

Background: This study's objective was to investigate the adverse effects of atypical antipsychotics (AAPs) on the metabolic, hematological, and endocrinological systems in the inpatient environment for children and adolescents with diverse psychiatric disorders.

Methods: A retrospective assessment of 208 children's and adolescents' medical records was conducted. All patients were on AAP monotherapy.

Retrospective evaluation of "Rods and Rings" pattern detected in the anti-nuclear antibody (ANA) indirect immunofluorescence (IIF) test.

Introduction: Anti-rods and rings (anti-RR) antibodies have recently been described as a cytoplasmic pattern in IIF-based screening of autoantibodies on HEp-2 cells and ICAP has named it as AC-23. It is most frequently related to drug-induced antibody generation. This study aimed to investigate the clinical significance of AC-23 positivity and its relevance to the diagnosis and/or follow-up of the associated diseases and/or drug use.

Illness-related outcomes of illicit substance use disorder in adolescents with early onset schizophrenia: a multicenter study.

Objectives: Lifetime co-occurring substance use disorders are common at the time of presentation for the treatment of primary psychosis. Our aim was to investigate the clinical characteristics of adolescents with early-onset schizophrenia/schizoaffective disorder (EOS), categorized as either with (EOS + SUD) or without SUD (non-SUD/EOS), in a multi-center sample.

Methods: Between 2016 and 2022, 255 patients were evaluated across three tertiary-care inpatient units.

Neurocognition and social cognition in youth and young adults at ultra-high-risk for psychosis and bipolar disorder.

Background: Schizophrenia and bipolar disorder are associated with significant deficits in neurocognition and social cognition. Unlike the studies in chronic stages of these disorders, very limited information is available regarding neurocognitive and social-cognitive impairment before the onset of bipolar disorder. Our main aim was to investigate the differences in neurocognition and social cognition between individuals at ultra-high risk for psychosis (UHR-P) and bipolar disorder (UHR-BD).
