Influence of Sex and Diagnosis on Clinical Variables and Neurocognitive Performance in Severe Mental Illness. Results From the PsyCourse Study.

Introduction: Bipolar disorder (BD) and schizophrenia (SZ) are serious mental illnesses (SMI) with overlapping symptoms but distinct differences in onset and course. Sex differences are an area of growing interest in SMI. This study aims to examine potential interactions between sex and diagnosis across a broad range of variables, to compare males and females within SZ and BD, and to investigate sex-specific group differences.

Unravelling the Link Between Body Mass Index and Cognitive Performance in Individuals With Bipolar Disorder and Exploration of PRS Moderation Effect: Findings From the PsyCourse Study.

Introduction: Bipolar disorder (BD) is a severe mental disorder characterized by extreme mood swings, often accompanied by metabolic comorbidities, such as cardiovascular disease, which increase mortality and reduce quality of life. Both metabolic dysfunctions and BD are associated with cognitive dysfunction. Body mass index (BMI) is closely linked to metabolic health and cognitive performance.

Implementation and Adherence of a Custom Mobile Application for Anonymous Bidirectional Communication Among Nearly 4000 Participants: Insights from the Longitudinal RisCoin Study.

: The longitudinal RisCoin study investigated risk factors for COVID-19 vaccination failure among healthcare workers (HCWs) and patients with inflammatory bowel disease (IBD) at a University Hospital in Germany. Since the hospital served as the study sponsor and employer of the HCW, we implemented a custom mobile application. We aimed to evaluate the implementation, adherence, benefits, and limitations of this study's app.

Pathway-Specific Polygenic Scores for Predicting Clinical Lithium Treatment Response in Patients With Bipolar Disorder.

Background: Polygenic scores (PGSs) hold the potential to identify patients who respond favorably to specific psychiatric treatments. However, their biological interpretation remains unclear. In this study, we developed pathway-specific PGSs (PS) for lithium response and assessed their association with clinical lithium response in patients with bipolar disorder.
