Estudio de los mecanismos fisiopatológicos asociados al inicio y curso de los trastornos del neurodesarrollo en prematuros (estudio PeriSTRESS-PremTEA): justificación, objetivos, diseño y descripción de la muestra
Resumen Introduccion Los factores genetico-ambientales y las vias fisiopatologicas que condicionan la evolucion de forma diferencial a un trastorno de neurodesarrollo (TN) en la poblacion de grandes prematuros (GP) y prematuros extremos (PE) siguen siendo en gran medida desconocidos. Tampoco disponemos a fecha de hoy de marcadores biologicos potencialmente predictivos de TN en estos ninos. El proyecto PeriSTRESS-PremTEA tiene como objetivo estudiar de forma prospectiva, en GP/PE: (i) la aparicion/curso de rasgos y diagnostico TN hasta los 6 anos de vida, (ii) factores de riesgo de aparicion de TN desde la etapa prenatal hasta los 6 anos, (ii) perfiles de biomarcadores en orina predictivos d…

A polygenic approach to the association between smoking and schizophrenia.
Smoking prevalence in schizophrenia is considerably larger than in general population, playing an important role in early mortality. We compared the polygenic contribution to smoking in schizophrenic patients and controls to assess if genetic factors may explain the different prevalence. Polygenic risk scores (PRSs) for smoking initiation and four genetically correlated traits were calculated in 1108 schizophrenic patients (64.4% smokers) and 1584 controls (31.1% smokers). PRSs for smoking initiation, educational attainment, body mass index and age at first birth were associated with smoking in patients and controls, explaining a similar percentage of variance in both groups. Attention-defi…
Evidence, and replication thereof, that molecular-genetic and environmental risks for psychosis impact through an affective pathway
AbstractBackgroundThere is evidence that environmental and genetic risk factors for schizophrenia spectrum disorders are transdiagnostic and mediated in part through a generic pathway of affective dysregulation.MethodsWe analysed to what degree the impact of schizophrenia polygenic risk (PRS-SZ) and childhood adversity (CA) on psychosis outcomes was contingent on co-presence of affective dysregulation, defined as significant depressive symptoms, in (i) NEMESIS-2 (n = 6646), a representative general population sample, interviewed four times over nine years and (ii) EUGEI (n = 4068) a sample of patients with schizophrenia spectrum disorder, the siblings of these patients and controls.ResultsT…

The contribution of cannabis use to variation in the incidence of psychotic disorder across Europe (EU-GEI): a multicentre case-control study.
Background: Cannabis use is associated with increased risk of later psychotic disorder but whether it affects incidence of the disorder remains unclear. We aimed to identify patterns of cannabis use with the strongest effect on odds of psychotic disorder across Europe and explore whether differences in such patterns contribute to variations in the incidence rates of psychotic disorder. Methods: We included patients aged 18–64 years who presented to psychiatric services in 11 sites across Europe and Brazil with first-episode psychosis and recruited controls representative of the local populations. We applied adjusted logistic regression models to the data to estimate which patterns of canna…
Unraveling the relationship of loneliness and isolation in schizophrenia: Polygenic dissection and causal inference
ABSTRACTThere is increasing recognition of the association between loneliness and social isolation (LNL-ISO) with schizophrenia. Here, we demonstrate significant LNL-ISO polygenic score prediction on schizophrenia in an independent case-control sample (N=3,488). We then dissect schizophrenia predisposing variation into subsets of variants based on their effect on LNL-ISO. Genetic variation with concordant effects in both phenotypes show significant SNP-based heritability enrichment, higher polygenic predictive ability in females and positive covariance with other mental disorders such as depression, anxiety, attention-deficit hyperactivity, alcohol use disorder, and autism. Conversely, gene…
