Background: Multiple genetic and environmental risk factors play a role in the development of both schizophrenia-spectrum disorders and affective psychoses. How they act in combination is yet to be clarified.
Methods: We analyzed 573 first episode psychosis cases and 1005 controls, of European ancestry.
Background: The association between cannabis and psychosis is established, but the role of underlying genetics is unclear. We used data from the EU-GEI case-control study and UK Biobank to examine the independent and combined effect of heavy cannabis use and schizophrenia polygenic risk score (PRS) on risk for psychosis.
Methods: Genome-wide association study summary statistics from the Psychiatric Genomics Consortium and the Genomic Psychiatry Cohort were used to calculate schizophrenia and cannabis use disorder (CUD) PRS for 1098 participants from the EU-GEI study and 143600 from the UK Biobank.
Background: Cannabis use and familial vulnerability to psychosis have been associated with social cognition deficits. This study examined the potential relationship between cannabis use and cognitive biases underlying social cognition and functioning in patients with first episode psychosis (FEP), their siblings, and controls.
Methods: We analyzed a sample of 543 participants with FEP, 203 siblings, and 1168 controls from the EU-GEI study using a correlational design.
Childhood adversity is associated with various clinical dimensions in psychosis; however, how genetic vulnerability shapes the adversity-associated psychopathological signature is yet to be studied. We studied data of 583 First Episode Psychosis (FEP) cases from the EU-GEI FEP case-control study, including Polygenic risk scores for major depressive disorder (MDD-PRS), bipolar disorder (BD-PRS) and schizophrenia (SZ-PRS); childhood adversity measured with the total score of the Childhood Trauma Questionnaire (CTQ); and positive, negative, depressive and manic psychopathological domains from a factor model of transdiagnostic dimensions. Genes and environment interactions were explored as a departure from a multiplicative effect of PRSs and total CTQ on each dimension.

Methods: The present study is cross-sectional and comprises 119 patients with axial SpA and 198 patients with PsA. Clinical data were collected by standardized and self-reported instruments.
Background: We examined whether cannabis use contributes to the increased risk of psychotic disorder for non-western minorities in Europe.
Methods: We used data from the EU-GEI study (collected at sites in Spain, Italy, France, the United Kingdom, and the Netherlands) on 825 first-episode patients and 1026 controls. We estimated the odds ratio (OR) of psychotic disorder for several groups of migrants compared with the local reference population, without and with adjustment for measures of cannabis use.
Aims of the present study were to prospectively assess psychosocial functioning trajectories during the COVID pandemic and the possible impact of sociodemographic variables, as well as of COVID-19 pandemic-related factors, on these trajectories, in a sample of patients with pre-existing severe mental disorders. Moreover, we aimed at identifying predictors of impairment in psychosocial functioning over a period of 9 months of COVID-19 pandemic. Patients were recruited during the 3rd wave of the COVID-19 pandemic (T0, March-April 2021) while strict containment measures were applied in Italy, and reassessed after 3 months (T1, June-July 2021), and after 6 months from T1 (T2- November-December 2021), during the 4th wave of COVID pandemic.

A sample of 527 subjects, with different DSM-5 diagnoses, was enrolled at nine Italian psychiatric outpatient services. Assessments at T0 and T1 included the Generalized Anxiety Disorder 7-Item (GAD-7) for anxiety symptoms, and the Patient Health Questionnaire-9 (PHQ-9) for depressive symptoms.

The aim of this study is to assess the prevalence of fatigue in patients with axSPA, and to investigate possible non-disease-related determinants, with a special focus on depression.
Methods: Patients with axSpA were assessed using the Chalder's Fatigue Questionnaire (CFQ) for fatigue, and the depression subscale of the Hospital Anxiety and Depression Scale (HADS-D) for depression.
Background: A better characterization of educational processes during psychiatry training is needed, both to foster personal resilience and occupational proficiency.
Methods: An adequate coverage of medical residents at the national level was reached (41.86% of the total reference population, 29 out of 36 training centers-80.
Background: Childhood adversity and cannabis use are considered independent risk factors for psychosis, but whether different patterns of cannabis use may be acting as mediator between adversity and psychotic disorders has not yet been explored. The aim of this study is to examine whether cannabis use mediates the relationship between childhood adversity and psychosis.
Methods: Data were utilised on 881 first-episode psychosis patients and 1231 controls from the European network of national schizophrenia networks studying Gene-Environment Interactions (EU-GEI) study.
Objectives: This study aimed to compare the health-related quality of life scores among rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis and to evaluate socio-demographic and clinical determinantes of quality of life across diseases.
Methods: The sample comprised 490 patients with rheumatoid arthritis, 198 with psoriatic arthritis, and 119 with spondyloarthritis who completed a series of health examinations and self-reported questionnaires. Quality of life was evaluated using the Short-Form 36 Health Survey, disease activity by DAS28-CRP, DAPSA, and ASDAS-CRP (for rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis, respectively), depression and anxiety using the Hospital Anxiety and Depression Scale.

This study investigated if the association between childhood maltreatment and cognition among psychosis patients and community controls was partially accounted for by genetic liability for psychosis. Patients with first-episode psychosis (N = 755) and unaffected controls (N = 1219) from the EU-GEI study were assessed for childhood maltreatment, intelligence quotient (IQ), family history of psychosis (FH), and polygenic risk score for schizophrenia (SZ-PRS). Controlling for FH and SZ-PRS did not attenuate the association between childhood maltreatment and IQ in cases or controls.

However, it is not known why only some exposed individuals go on to develop psychosis. One possibility is pre-existing polygenic vulnerability.
View Article and Find Full Text PDFBackground: While cannabis use is a well-established risk factor for psychosis, little is known about any association between reasons for first using cannabis (RFUC) and later patterns of use and risk of psychosis.
Methods: We used data from 11 sites of the multicentre European Gene-Environment Interaction (EU-GEI) case-control study. 558 first-episode psychosis patients (FEPp) and 567 population controls who had used cannabis and reported their RFUC.
Serotonergic and dopaminergic systems are involved in the regulation of mood and reactivity to psychological stress. This study explores, in a sample of first episode psychosis (FEP) patients, whether more severe depressive symptoms were found in those who: (1) experienced a major stressful event in the 6 months preceding illness onset; and (2) were homozygous for the COMT Val158 allele or carrying the S allele of 5-HTTLPR. A total of 186 FEP patients recruited were assessed using the Hamilton Rating Scale for Depression (HAMD) for depressive symptoms.

The study aims to assess patients' beliefs about the necessity and concerns regarding pharmacotherapy in rheumatic diseases and attitude styles, and to investigate the association between clinical factors and negative beliefs about medication. A sample of 712 patients affected by Rheumatoid Arthritis, Psoriatic Arthritis, Ankylosing Spondylitis was enrolled.

The aim of this study was to prospectively assess post-traumatic stress disorder (PTSD) and post-traumatic stress symptoms (PTSS) in patients with mental disorders, during the 3rd wave of the infection (T0, March-April 2021) while strict containment measures were applied in Italy, and after 3 months (T1, June-July 2021), with reduced restrictive measures. A total sample of 527 subjects, with different DSM-5 diagnoses, was consecutively enrolled at nine Italian psychiatric outpatient services.

This study explored the association between CA, cortisol and psychotic symptoms in FEP patients.
Methods: 81 FEP patients were enrolled.
