BACKGROUND: Childhood abuse is highly prevalent in psychosis patients, but whether/how it affects hypothalamic-pituitary-adrenal (HPA) axis at the onset of psychosis remains unclear. We aimed to investigate the effects of severity of childhood abuse on HPA axis activity, in first-episode psychosis (FEP) and healthy controls. METHODS: We recruited 169 FEP patients and 133 controls with different degrees of childhood physical and sexual abuse (i.e. no abuse exposure, non-severe abuse exposure, and severe abuse exposure)...

Hypothalamic-pituitary-adrenal (HPA) axis alterations in at-risk mental states (ARMS) resemble those observed in established psychosis but are less consistent. We aimed to explore HPA axis abnormalities in both first-episode psychosis (FEP) and ARMS patients, while controlling for psychopathological symptoms. We studied 21 ARMS, 34 FEP patients and 34 healthy subjects. Clinical assessment included psychopathological symptoms (positive, negative, disorganized, excited and depressive symptoms) and stress measures...

BACKGROUND: Accumulating evidence indicates that schizophrenia might be accompanied by abnormal vascularization. Vascular endothelial growth factor (VEGF) is one of key molecules involved in the development of vessels with vasodilatory activities. OBJECTIVES: We aimed to perform a systematic review and meta-analysis of studies investigating serum or plasma levels of VEGF in patients with schizophrenia and first-episode psychosis (FEP). METHODS: Electronic databases were searched from their inception until 18th Apr 2018...

BACKGROUND: Hyperprolactinemia is a common side-effect of antipsychotics (APs), which may trigger serious secondary problems and compromise the adherence to treatment which is crucial for prognosis, especially in patients presenting with a first-episode of psychosis (FEP). AIMS: We evaluated, in some cases for the first time, the effect of polymorphisms in multiple candidate genes on serum prolactin (PRL) levels in an AP-treated FEP cohort recruited in the multicenter PEPs study (Phenotype - genotype and environmental interaction; Application of a predictive model in first psychotic episodes)...

BACKGROUND: Disability encompasses impairments, activity limitations, and restrictions on participation. Improvement in functioning has therefore become a crucial outcome of treatment in psychosis. OBJECTIVE: The main aim of this study was to analyze the potential relationship between suicidal behavior after first episode of psychosis (FEP) and family disability. The second aim was to find out whether personality traits are associated with disability dimensions...

Specialized treatment for first episode psychosis offers clients a menu of services coordinated within a specialized treatment team. To enhance the impact of these services, promoting engagement and preventing early treatment drop-out is critical. However, engagement is poorly tracked and typically quantified through proxy variables such as session attendance, medication adherence, or working alliance. The aim of this study is to introduce and pilot a new measure of engagement for first episode psychosis coordinated specialty care, the Client Engagement and Service Use Scale (CENSUS)...

Over the last twenty years, a lot of early intervention services operate worldwide with the aim of offering assistance and promoting the early diagnosis and management, not only of people who experience a first episode of psychosis but also of individuals that are at high risk of developing psychosis. The early intervention services that operate in other countries have been reviewed in correlation with the current status of early intervention services for psychosis in Greece. Early intervention services were first established in Australia, and now hundreds of similar programs exist in Europe, North America and Asia...

BACKGROUND: Mental health conditions account for 52.8 million (4.9-6.3%) emergency department (ED) visits in the United States. Psychotic conditions are responsible for approximately 10% of all mental health presentations. OBJECTIVE: We aimed to determine the underlying etiology and characteristics of patients presenting to the ED with a first episode of psychotic symptoms. METHODS: Medical records of 159 African, Asian, white, and mixed-race patients were prospectively reviewed...

Ongoing research suggests preliminary, though not entirely consistent, evidence of neural abnormalities in signalling prediction errors in schizophrenia. Supporting theories suggest mechanistic links between the disruption of these processes and the generation of psychotic symptoms. However, it is unknown at what stage in the pathogenesis of psychosis these impairments in prediction-error signalling develop. One major confound in prior studies is the use of medicated patients with strongly varying disease durations...

BACKGROUND: Verbal learning and memory are impaired not only in patients with a first episode of psychosis (FEP) but also-to a lower extent-in those with an at-risk mental state for psychosis (ARMS). However, little is known about the specific nature of these impairments. Hence, we aimed to study learning and memory processes in ARMS and FEP patients by making use of structural equation modelling. METHODS: Verbal learning was assessed with the California Verbal Learning Test (CVLT) in 98 FEP patients, 126 ARMS patients and 68 healthy controls (HC) as part of the Basel early detection of psychosis (FePsy) study...

Prior functional magnetic resonance imaging (fMRI) studies have investigated the neural mechanisms underlying cognitive control in patients with psychosis with findings of both hypo- and hyperfrontality. One factor that may contribute to inconsistent findings is the use of complex and polyfactorial tasks to investigate frontal lobe functioning. In the current study we employed a simple response conflict task during fMRI to examine differences in brain activation between patients experiencing their first-episode of psychosis (n = 33) and age- and sex-matched healthy volunteers (n = 33)...

People with psychotic disorders show abnormalities in several organ systems in addition to the central nervous system (CNS); and this contributes to excess mortality. However, it is unclear how strong the evidence is for alterations in non-CNS systems at the onset of psychosis, how the alterations in non-CNS systems compare to those in the CNS, or how they relate to symptoms. Here, we consider these questions, and suggest potential models to account for findings. We conducted a systematic meta-review to summarize effect sizes for both CNS (focusing on brain structural, neurophysiological, and neurochemical parameters) and non-CNS dysfunction (focusing on immune, cardiometabolic, and hypothalamic-pituitary-adrenal (HPA) systems) in first-episode psychosis (FEP)...

AIM: Individuals with serious mental illnesses have a small increased risk of engaging in violence or legal involvement compared to the general population. This seems to be particularly true for young adults experiencing early stages of psychosis. This study analysed the prevalence of and risk factors for reports of violence and legal involvement in a sample of young adults receiving Coordinated Specialty Care for early non-affective psychosis. METHODS: A total of 373 young adults (ages 16-30) within 2 years of the onset of non-affective psychosis were enrolled in 10 Coordinated Specialty Care sites in New York State from October 2013 to August 2016...

Schizophrenia (SCH) is a heterogeneous disorder, deriving from a potential multitude of etiopathogenetic factors. During the past few years there has been an increasing interest in the role of circulating amino acids (AAs) and biogenic amines (BAs) in the pathophysiology of SCH. In the present study, we aimed to provide an insight into the potential role of alterations in levels of AAs and BAs as well as examine their more specific metabolic shifts in relation to early stage of SCH. We measured 21 AAs and 17 BAs in serum samples of patients with first-episode psychosis (FEP) before and after 7-month antipsychotic treatment in comparison to control subjects (CSs)...

We aimed to profile a broad panel of inflammatory markers in patients with schizophrenia and healthy controls. Additionally, we performed a meta-analysis of chemokine alterations that have not been subjected to quantitative synthesis so far. We recruited 78 patients with schizophrenia and 78 healthy controls, and measured inflammatory markers using the Luminex technology. After adjustment for multiple testing, we found elevated levels of interleukin (IL)-1 receptor antagonist (IL-1RA), IL-6, IL-7, IL-8, IL-9, IL-10, IL-13, interferon-γ, eotaxin-1, granulocyte-macrophage colony-stimulating factor (GM-CSF), monocyte chemoattractant protein-1 (MCP-1), platelet-derived growth factor with two B subunits (PDGF-BB), macrophage inflammatory protein (MIP)-1α, MIP-1β, vascular endothelial growth factor A (VEGF-A) and RANTES in multiple-episode schizophrenia (MES) patients...

Lately, several studies started to investigate the existence of links between cannabis use and psychotic disorders. This work proposes a refined Machine Learning framework for understanding the links between cannabis use and 1st episode psychosis. The novel framework concerns extracting predictive patterns from clinical data using optimised and post-processed models based on Gaussian Processes, Support Vector Machines, and Neural Networks algorithms. The cannabis use attributes' predictive power is investigated, and we demonstrate statistically and with ROC analysis that their presence in the dataset enhances the prediction performance of the models with respect to models built on data without these specific attributes...

Patients with obsessive-compulsive disorder (OCD) show dysfunctions of the fronto-striatal circuitry, which imply corresponding oculomotor deficits including smooth pursuit eye movements (SPEM). However, evidence for a deficit in SPEM is inconclusive, with some studies reporting reduced velocity gain while others did not find any SPEM dysfunctions in OCD patients. Interestingly, psychosis-like traits have repeatedly been linked to both OCD and impaired SPEM. Here, we examined a large sample of n = 168 patients with OCD, n = 93 unaffected first-degree relatives and n = 171 healthy control subjects to investigate whether elevated levels of schizotypy and SPEM deficits represent potential endophenotypes of OCD...
