- Polygenic risk scores and the prediction of onset of mood and psychotic disorders in adolescents and young adults October 3, 2023CONCLUSIONS: The findings need replication. However, this exploratory study suggests that combining PRS with other risk factors has the potential to improve outcome prediction in youth.Jan Scott
- GWAS Meta-Analysis of Suicide Attempt: Identification of 12 Genome-Wide Significant Loci and Implication of Genetic Risks for Specific Health Factors October 1, 2023CONCLUSIONS: This multi-ancestry analysis of suicide attempt identified several loci contributing to risk and establishes significant shared genetic covariation with clinical phenotypes. These findings provide insight into genetic factors associated with suicide attempt across ancestry admixture populations, in veteran and civilian populations, and in attempt versus death.Anna R Docherty
- Risk of suicidal behavior as a function of alcohol use disorder typologies: A Swedish population-based study September 27, 2023CONCLUSIONS: Among people in Sweden, considering alcohol use disorder (AUD) heterogeneity appears to be a meaningful way to evaluate suicide risk. The highest risk of suicide attempt and death occurs in the externalizing subtype of AUD, followed by the minimal psychopathology subtype, and then the internalizing subtype.Séverine Lannoy
- Polygene risk scores and randomized experiments September 11, 2023We explore Madole & Harden's (2022) suggestion that single-nucleotide polymorphism (SNP)/trait correlations are analogous to randomized experiments and thus can be given a causal interpretation.Lauren N Ross
- Migration and risk of schizophrenia and bipolar disorder: A Swedish national study September 4, 2023CONCLUSIONS: Age at migration, sex, and region of origin affect risk of SCZ and BD. Further research is required to determine how migration-related factors influence disease etiology and the receipt of these diagnoses.Natassia Robinson
- The Impact of the Good Behavior Game on Risk for Drug Use Disorder in an Agent-Based Model of Southern Sweden August 31, 2023CONCLUSIONS: This work provides support for the impact of improving school achievement on long-term risks of developing DUD. It also demonstrated the value of using simulation modeling calibrated with data from a real population to estimate the impact of an intervention applied at a population level.Sara L Lönn
- Effects of smoking on genome-wide DNA methylation profiles: A study of discordant and concordant monozygotic twin pairs August 29, 2023CONCLUSIONS: In conclusion, by analysing data from monozygotic twins, we robustly demonstrate that DNA methylation level in human blood cells is reactive to cigarette smoking.Jenny van Dongen
- The heritability of blood-based biomarkers related to risk of Alzheimer's disease in a population-based sample of early old-age men August 25, 2023INTRODUCTION: Despite their increased application, the heritability of Alzheimer's disease (AD)-related blood-based biomarkers remains unexplored.Nathan A Gillespie
- Genetic associations between alcohol phenotypes and life satisfaction: a genomic structural equation modelling approach August 18, 2023Alcohol use (i.e., quantity, frequency) and alcohol use disorder (AUD) are common, associated with adverse outcomes, and genetically-influenced. Genome-wide association studies (GWAS) identified genetic loci associated with both. AUD is positively genetically associated with psychopathology, while alcohol use (e.g., drinks per week) is negatively associated or NS related to psychopathology. We wanted to test if […]Kaitlin E Bountress
- Integrative Post-Genome-Wide Association Study Analyses Relevant to Psychiatric Disorders: Imputing Transcriptome and Proteome Signals August 17, 2023BACKGROUND: The genome-wide association study (GWAS) is a common tool to identify genetic variants associated with complex traits, including psychiatric disorders (PDs). However, post-GWAS analyses are needed to extend the statistical inference to biologically relevant entities, e.g., genes, proteins, and pathways. To achieve this goal, researchers developed methods that incorporate biologically relevant intermediate molecular phenotypes, […]Huseyin Gedik
- Missingness adapted group informed clustered (MAGIC)-LASSO: a novel paradigm for phenotype prediction to improve power for genetic loci discovery August 7, 2023Introduction: The availability of large-scale biobanks linking genetic data, rich phenotypes, and biological measures is a powerful opportunity for scientific discovery. However, real-world collections frequently have extensive missingness. While missing data prediction is possible, performance is significantly impaired by block-wise missingness inherent to many biobanks. Methods: To address this, we developed Missingness Adapted Group-wise Informed […]Amanda Elswick Gentry
- Methylome-wide association study of anxiety disorders August 4, 2023Anxiety Disorders (ANX) such as panic disorder, generalized anxiety disorder, and phobias, are highly prevalent conditions that are moderately heritable. Evidence suggests that DNA methylation may play a role, as it is involved in critical adaptations to changing environments. Applying an enrichment-based sequencing approach covering nearly 28 million autosomal CpG sites, we conducted a methylome-wide […]John M Hettema
- Exposure to alcohol outlets and risk of suicidal behavior in a Swedish cohort of young adults August 1, 2023CONCLUSIONS: Although effect sizes are small, living in a neighborhood with bars and/or government alcohol outlets may increase suicidal behavior among young adults. Individuals with higher genetic liability for SA are slightly more susceptible to these exposures.Alexis C Edwards
- Common genetic and environmental risk for personality disorders and psychotic-like experiences in young adult twins July 27, 2023CONCLUSION: We found that the co-occurrence between PDs and PLE is the best explained by shared genetic determinants, with minor contributions from environmental factors. Interestingly, borderline PD was highly genetically correlated with PLE, warranting molecular genetic studies of this association.Martin Tesli
- Study protocol for the Mindful Moms Study: A randomized controlled trial evaluating a mindful movement intervention for marginalized pregnant people experiencing depression July 27, 2023More than 1 in 5 pregnant people in the United States experience depressive symptoms. Although treatments exist, many people remain under- or un-treated due to concerns about stigma, side effects, and costs of medications or psychotherapy, particularly those who are marginalized (defined as those who are minoritized, low-income, or with low-educational attainment). Further, the standard […]Patricia A Kinser
- The effect of a reduction in irrational beliefs on Posttraumatic Stress Disorder (PTSD), depression, and anxiety symptoms in a group treatment for post-9/11 Veterans July 24, 2023Previous research has indicated that a Rational Emotive Behavior Therapy (REBT)-Informed Group focused on changing irrational beliefs to address comorbid depression and anxiety (as well as anger and guilt) in a combat Veteran population diagnosed with Posttraumatic Stress Disorder (PTSD) demonstrated significant reductions in depression and PTSD symptoms at posttreatment. However, mechanisms of change associated […]Allen B Grove
- The moderation of the genetic risk for alcohol and drug use disorders in a Swedish national sample by the genetic aptitude for educational attainment July 14, 2023CONCLUSIONS AND RELEVANCE: The genetic propensity to high educational attainment robustly moderates the genetic risk for both AUD and DUD such that the impact of the genetic liability to AUD and DUD on the risk of illness is substantially attenuated in those with high v. low GAEA. This effect is not appreciably mediated by the […]Kenneth S Kendler
- Ryssia Wolfsohn's 1907 dissertation on "the heredity of dementia praecox" July 13, 2023In the 19th century, psychiatric genetic studies typically utilized a generic category of "insanity." This began to change after 1899, with the publication of Kraepelin's 6th edition containing, among other disorders, his mature concept of dementia praecox (DP). We here review an article published by Ryssia Wolfsohn in 1907 from her dissertation at the University […]Kenneth S Kendler
- Environment-by-PGS Interaction in the Classical Twin Design: An Application to Childhood Anxiety and Negative Affect July 13, 2023One type of genotype-environment interaction occurs when genetic effects on a phenotype are moderated by an environment; or when environmental effects on a phenotype are moderated by genes. Here we outline these types of genotype-environment interaction models, and propose a test of genotype-environment interaction based on the classical twin design, which includes observed genetic variables […]Susanne Bruins
- The Nature of the Familial Risk for Psychosis in Bipolar Disorder July 13, 2023CONCLUSIONS: The BD-associated risk for psychosis impacts most strongly on mood disorders, moderately on episodic psychotic syndromes, and least on chronic psychotic disorders. These results support prior clinical studies suggesting a qualitative difference in the familial substrate for psychosis occurring in BD and SZ.Kenneth S Kendler
