Published: March 2023

Purpose: Early treatment of psychotic illness improves outcomes, reduces relapse rates and should not be delayed. Cariprazine is a promising antipsychotic drug and may be a valuable resource when clinicians are in doubt if psychotic symptoms are due to schizophrenia or bipolar disorder.

Materials And Methods: We conducted a systematic review and meta-analysis that included seven studies (n = 2896) analyzing the effect of cariprazine in psychotic symptoms assessed by the positive and negative symptoms scale (PANSS).

Results: We found cariprazine to be significantly superior to placebo (Hedges' g = 0.40; 95% CI 0.32-0.49) for acute psychosis independently of primary psychiatric diagnosis and also to be superior to placebo for both schizophrenia (Hedges' g = 0.39; 95% CI 0.29-0.50) and bipolar patients (Hedges' g = 0.43; 95% CI 0.27-0.58).

Conclusions: We propose that cariprazine may be useful in treating psychosis independently of nosological differentiation at the beginning of the treatment Key pointsEarly treatment of psychotic illness with antipsychotic medications improves outcomes and reduces relapse rates.Cariprazine was found to be significantly superior to placebo for acute psychosis independently of primary psychiatric diagnosis.Cariprazine may be useful in treating psychosis independently of nosological differentiation between schizophrenia and bipolar disorder at the beginning of the treatment.

Learning Health Systems (LHSs) promise meaningful health care improvement through the ongoing use of data, including the lived experience of diverse constituents, such as people participating in and providing services. Most LHSs operate within a specific healthcare system, typically hospital-based, under a common electronic health record (EHR) and management structure. The Early Psychosis Intervention Network in Texas (EPINET-TX) is a novel case study of a developing LHS across 16 independent community mental health clinics operating state-funded coordinated specialty care (CSC) programs for early psychosis.

Background: In Germany, there are hardly any studies that investigated the care pathways in the early course of psychosis and the duration of untreated psychosis (DUP) and took the migration background into account.

Objective: The study examined whether young adults with (PwM) and without a migration background (PoM) who had a first psychotic episode or first contact with the psychiatric care system within the last 5 years differ in their utilization of care services and DUP.

Material And Methods: The data collection and post hoc analyses were carried out as a part of a cohort study (84 inpatients) at the Early Intervention and Therapy Center (FRITZ) in Berlin.

The existing systematic reviews addressing barriers to clozapine prescribing primarily focus on clinical staff's attitudes and perceived barriers to prescribing. However, a preliminary literature search revealed additional literature on the subject not previously included in systematic reviews, including literature on patient perspectives.

Catatonia may manifest as an independent entity or as a feature of a neuropsychiatric or medical illness. While electroconvulsive therapy (ECT) is the gold standard treatment for catatonia, it is typically administered if the patient's symptoms fail to respond to benzodiazepines. We describe the case of a 22-year-old male with Budd Chiari induced cirrhosis and no prior psychiatric history, who presented with symptoms of psychosis and hepatic encephalopathy, was treated in the ICU for multi-factorial delirium, developed symptoms of catatonia that failed to respond to lorazepam, ultimately requiring ECT with a favorable response.
