Sex differences in prolactin levels and clinical outcomes in patients with a first psychotic episode.

Aim: To analyze the clinical, neurocognitive, and functional impact of prolactin levels according to sex in patients with a First Episode Psychosis (FEP).

Methods: We measured prolactin levels in 221 non-affective FEP patients treated with antipsychotics (AP) and 224 healthy controls, at baseline and 2-year follow-up. We examined whether the relationships between clinical and functional variables were mediated by prolactin, controlling for antipsychotic use, according to sex.

Emotional intelligence and neurocognition profiles in first-episode psychosis: A two-year follow-up study.

Emotional intelligence (EI) and neurocognition (NC) impairments are common in first-episode psychosis (FEP), yet their evolution over time remains unclear. This study identified patient profiles in EI and NC performance in FEP. 98 adult FEP patients and 128 healthy controls (HCs) were tested on clinical, functional, EI, and NC variables at baseline and two-year follow-up (FUP).

Clozapine use in the first two years after first-episode psychosis in a real-world clinical sample.

Background: Approximately 20-30% of patients with schizophrenia fail to respond to antipsychotic treatment and are considered treatment resistant (TR). Although clozapine is the treatment of choice in these patients, in real-world clinical settings, clinicians often delay clozapine initiation, especially in first-episode psychosis (FEP).

Aim: The main aim of this study was to describe prescription patterns for clozapine in a sample of patients diagnosed with FEP and receiving specialized treatment at a university hospital.

Negative symptoms and sex differences in first episode schizophrenia: What's their role in the functional outcome? A longitudinal study.

Introduction: Negative symptoms (NS) include asociality, avolition, anhedonia, alogia, and blunted affect and are linked to poor prognosis. It has been suggested that they reflect two different factors: diminished expression (EXP) (blunted affect and alogia) and amotivation/pleasure (MAP) (anhedonia, avolition, asociality). The aim of this article was to examine potential sex differences among first-episode schizophrenia (FES) patients and analyze sex-related predictors of two NS symptoms factors (EXP and MAP) and functional outcome.

A comparison of PTSD and traumatic event rates in a clinical sample of non-refugee immigrants and native-born individuals with a psychotic disorder: a case-control study.

Migration is a multi-stage social process linked to traumatic event exposure and a notably increased risk of psychosis. Although these conditions affect refugee and non-refugee immigrants, prior trauma research has focused mainly on the refugee population. To compare and describe the rate and the clinical characterization of PTSD and traumatic events between non-refugee immigrants and native-born individuals with psychotic disorder.

Incidence rate and distinctive characteristics of first episode psychosis during the COVID-19 pandemic: a multicenter observational study.

The COVID-19 pandemic has affected the mental health of people around the world. However, its impact on first-episode psychosis (FEP) remains unclear. The aim of this study was to determine the incidence rate (IR) and the clinical and sociodemographic characteristics of patients who developed FEP during the nine-month period following the COVID-19 outbreak in Spain and to compare these data to the corresponding period in the previous year.

Role of cyclin-dependent kinase 5 in psychosis and the modulatory effects of cannabinoids.

Cyclin-dependent kinase 5 (CDK5) is a serine/threonine kinase that has emerged as a key regulator of neurotransmission in complex cognitive processes. Its expression is altered in treated schizophrenia patients, and cannabinoids modulate CDK5 levels in the brain of rodents. However, the role of this kinase, and its interaction with cannabis use in first-episode psychosis (FEP) patients is still not known.

Posttraumatic Stress Symptoms, Physical Illness, and Social Adjustment Among Disaster Victims.

Objective: Posttraumatic stress disorder is one of the most studied outcomes after a disaster. Posttraumatic stress symptoms (PTSS) are maladaptive and disabling and can severely impair affected individuals' psychosocial functioning and quality of life. Consequently, the objective of this research is to investigate the prevalence of PTSS and physical illness among disaster victims.

Clinical Features, Neuropsychology and Neuroimaging in Bipolar and Borderline Personality Disorder: A Systematic Review of Cross-Diagnostic Studies.

Bipolar Disorder (BD) and Borderline Personality Disorder (BPD) have clinically been evolving as separate disorders, though there is still debate on the nosological valence of both conditions, their interaction in terms of co-morbidity or disorder spectrum and their distinct pathophysiology. The objective of this review is to summarize evidence regarding clinical features, neuropsychological performance and neuroimaging findings from cross-diagnostic studies comparing BD and BPD, to further caracterize their complex interplay. Using PubMed, PsycINFO and TripDataBase, we conducted a systematic literature search based on PRISMA guidelines of studies published from January 1980 to September 2019 which directly compared BD and BPD.
