Background: The aim of study was to analyze neurocognitive profiles in patients with first-episode psychosis (FEP) and patients with schizophrenia (SCH), and their correlations with other clinical features.

Subjects And Methods: We performed a multicentric cross sectional study including 100 FEP and 100 SCH recruited from three Croatian hospitals during 2015-2017. Assessment included a set of neurocognitive tests, psychiatric scales and self-reporting questionnaires. The main analysis was done by multigroup latent profile analysis.

Results: Multigroup latent profile analysis resulted in three structurally equivalent neurocognitive profiles ("Best", "Medium", "Worst"), with differences in the severity of neurocognitive deficits measured with successfulness in solving domain specific tasks. The "Best" profile was statistically significantly more prevalent in FEP and "Worst" profile in the SCH. Negative symptom score was the highest in patients with the "Worst" profile and the lowest among those with the "Best" profiles.

Conclusions: Differences in neurocognitive profiles between FEP and SCH appear to be quantitative rather than qualitative nature, possibly reflecting a specific trait of illness that may progress over time. Defining neurocognitive profiles from the first episode of psychosis could help in tailoring individualized treatment options with focus on neurocognitive and negative symptoms and possible influence on patients' overall clinical outcome.

Psychopharmacology (Berl)

December 2024

Department of Neuropsychology and Psychopharmacology, Faculty of Psychology and Neuroscience, Maastricht University, P.O. Box 616, Maastricht, 6200 MD, The Netherlands.

Rationale: Despite the growing scientific interest on mitragynine, the primary alkaloid in kratom (Mitragyna Speciosa), there is a lack of clinical trials in humans.

Objectives: This phase 1 study aimed to evaluate mitragynine's safety profile and acute effects on subjective drug experience, neurocognition, and pain tolerance.

Methods: A placebo-controlled, single-blind, within-subjects study was conducted in two parts.

3-Methylmethcathinone (3-MMC) is a designer drug that belongs to the group of synthetic cathinones. The compound has been scheduled in many jurisdictions because of public health concerns associated with excessive use. To date, there are no clinical studies that have evaluated the risk profile of 3-MMC in the recreational range of low to moderate doses.

Unlabelled: The aim of this research is to investigate whether ferroptosis occurs in the pathogenesis of perioperative neurocognitive disorders (PND), and to explore the function and underlying molecular mechanism of tsRNA in the regulation of ferroptosis in PND. A PND aged mice model was established and behavioral changes and ferroptosis occurrence were confirmed. The effect of ferroptosis inhibitor ferrostatin-1 (Fer-1) on PND mice was detected.
