Abstract: Summary: Genetics have nominated many schizophrenia risk genes and identified convergent signals between schizophrenia and neurodevelopmental disorders. However, functional interpretation of the nominated genes in the relevant brain cell types is often lacking. We executed interaction proteomics for six schizophrenia risk genes that have also been implicated in neurodevelopment in human induced cortical neurons. The resulting protein network is enriched for common variant risk of schizophrenia in Europeans and East Asians, is down-regulated in layer 5/6 cortical neurons of individuals affected by schizophrenia, and can complement fine-mapping and eQTL data to prioritize additional genes in GWAS loci. A sub-network centered on HCN1 is enriched for common variant risk and contains proteins (HCN4 and AKAP11) enriched for rare protein-truncating mutations in individuals with schizophrenia and bipolar disorder. Our findings showcase brain cell-type-specific interactomes as an organizing framework to facilitate interpretation of genetic and transcriptomic data in schizophrenia and its related disorders.

Abstract: Contains fulltext : 291574.pdf (Publisher’s version ) (Open Access) Left-right asymmetry is an important organizing feature of the healthy brain that may be altered in schizophrenia, but most studies have used relatively small samples and heterogeneous approaches, resulting in equivocal findings. We carried out the largest case-control study of structural brain asymmetries in schizophrenia, with MRI data from 5,080 affected individuals and 6,015 controls across 46 datasets, using a single image analysis protocol. Asymmetry indexes were calculated for global and regional cortical thickness, surface area, and subcortical volume measures. Differences of asymmetry were calculated between affected individuals and controls per dataset, and effect sizes were meta-analyzed across datasets. Small average case-control differences were observed for thickness asymmetries of the rostral anterior cingulate and the middle temporal gyrus, both driven by thinner left-hemispheric cortices in schizophrenia. Analyses of these asymmetries with respect to the use of antipsychotic medication and other clinical variables did not show any significant associations. Assessment of age- and sex-specific effects revealed a stronger average leftward asymmetry of pallidum volume between older cases and controls. Case-control differences in a multivariate context were assessed in a subset of the data (N = 2,029), which revealed that 7% of the variance across all structural asymmetries was explained by case-control status. Subtle case-control differences of brain macrostructural asymmetry may reflect differences at the molecular, cytoarchitectonic, or circuit levels that have functional relevance for the disorder. Reduced left middle temporal cortical thickness is consistent with altered left-hemisphere language network organization in schizophrenia.

Abstract: [Background]: Morphology of the human cerebral cortex differs across psychiatric disorders, with neurobiology and developmental origins mostly undetermined. Deviations in the tangential growth of the cerebral cortex during pre/perinatal periods may be reflected in individual variations in cortical surface area later in life., [Methods]: Interregional profiles of group differences in surface area between cases and controls were generated using T1-weighted magnetic resonance imaging from 27,359 individuals including those with attention-deficit/hyperactivity disorder, autism spectrum disorder, bipolar disorder, major depressive disorder, schizophrenia, and high general psychopathology (through the Child Behavior Checklist). Similarity of interregional profiles of group differences in surface area and prenatal cell-specific gene expression was assessed., [Results]: Across the 11 cortical regions, group differences in cortical area for attention-deficit/hyperactivity disorder, schizophrenia, and Child Behavior Checklist were dominant in multimodal association cortices. The same interregional profiles were also associated with interregional profiles of (prenatal) gene expression specific to proliferative cells, namely radial glia and intermediate progenitor cells (greater expression, larger difference), as well as differentiated cells, namely excitatory neurons and endothelial and mural cells (greater expression, smaller difference). Finally, these cell types were implicated in known pre/perinatal risk factors for psychosis. Genes coexpressed with radial glia were enriched with genes implicated in congenital abnormalities, birth weight, hypoxia, and starvation. Genes coexpressed with endothelial and mural genes were enriched with genes associated with maternal hypertension and preterm birth., [Conclusions]: Our findings support a neurodevelopmental model of vulnerability to mental illness whereby prenatal risk factors acting through cell-specific processes lead to deviations from typical brain development during pregnancy., This work was supported by the German Research Foundation (DFG Grant Nos.

Abstract: The present study examined the course of diagnosed alcohol use disorders (AUDs) in a cohort of Australian veterans of the Vietnam War (N = 388) who were assessed 22 and 36 years after returning home. Standardized interviews provided data on AUDs, posttraumatic stress disorder (PTSD), other psychiatric diagnoses, and combat exposure. Overall, 148 veterans (38.1%) had no history of alcohol-related diagnoses, 151 veterans (38.9%) had a past AUD diagnosis that was not current at the second assessment point, and 89 veterans (22.9%) had a current AUD diagnosis at the second assessment. Less education, lower intelligence test scores, and misconduct were individual risk factors for AUDs, as were first-interview diagnoses of PTSD, antisocial personality disorder, generalized anxiety, and dysthymia, but not depression; these variables were all nonsignificant after controlling for combat exposure and PTSD. Multinomial regression was used to assess the relative contributions of combat exposure and PTSD to the course of AUDs. Combat exposure and PTSD had different patterns of association with AUDs whereby combat exposure, but not PTSD, was associated with a history of AUDs, odds ratio (OR) = 1.02, but not with current AUDs, whereas PTSD, but not combat exposure, was associated with current AUDs, OR = 3.37. Current numbing and avoidance symptoms were associated with current AUDs, OR = 4.48. The results do not support a mutual maintenance model of PTSD and AUDs but are consistent with a self-medication model, which suggests treatment for PTSD may have beneficial effects on AUDs.

Abstract: Contains fulltext : 248656.pdf (Publisher’s version ) (Closed access) BACKGROUND: Sex differences in incidence and/or presentation of schizophrenia (SCZ), major depressive disorder (MDD), and bipolar disorder (BIP) are pervasive. Previous evidence for shared genetic risk and sex differences in brain abnormalities across disorders suggest possible shared sex-dependent genetic risk. METHODS: We conducted the largest to date genome-wide genotype-by-sex (G×S) interaction of risk for these disorders using 85,735 cases (33,403 SCZ, 19,924 BIP, and 32,408 MDD) and 109,946 controls from the PGC (Psychiatric Genomics Consortium) and iPSYCH. RESULTS: Across disorders, genome-wide significant single nucleotide polymorphism-by-sex interaction was detected for a locus encompassing NKAIN2 (rs117780815, p = 3.2 × 10(-8)), which interacts with sodium/potassium-transporting ATPase (adenosine triphosphatase) enzymes, implicating neuronal excitability. Three additional loci showed evidence (p < 1 × 10(-6)) for cross-disorder G×S interaction (rs7302529, p = 1.6 × 10(-7); rs73033497, p = 8.8 × 10(-7); rs7914279, p = 6.4 × 10(-7)), implicating various functions. Gene-based analyses identified G×S interaction across disorders (p = 8.97 × 10(-7)) with transcriptional inhibitor SLTM. Most significant in SCZ was a MOCOS gene locus (rs11665282, p = 1.5 × 10(-7)), implicating vascular endothelial cells. Secondary analysis of the PGC-SCZ dataset detected an interaction (rs13265509, p = 1.1 × 10(-7)) in a locus containing IDO2, a kynurenine pathway enzyme with immunoregulatory functions implicated in SCZ, BIP, and MDD. Pathway enrichment analysis detected significant G×S interaction of genes regulating vascular endothelial growth factor receptor signaling in MDD (false discovery rate-corrected p < .05). CONCLUSIONS: In the largest genome-wide G×S analysis of mood and psychotic disorders to date, there was substantial genetic overlap between the sexes. However, significant sex-dependent effects were enriched for genes related to neuronal development and immune and vascular functions across and within SCZ, BIP, and MDD at the variant, gene, and pathway levels.

Abstract: White matter abnormalities associated with schizophrenia have been widely reported, although the consistency of findings across studies is moderate. In this study, neuroimaging was used to investigate white matter pathology and its impact on whole-brain white matter connectivity in one of the largest samples of patients with schizophrenia. Fractional anisotropy (FA) and mean diffusivity (MD) were compared between patients with schizophrenia or schizoaffective disorder (n = 326) and age-matched healthy controls (n = 197). Between-group differences in FA and MD were assessed using voxel-based analysis and permutation testing. Automated whole-brain white matter fiber tracking and the network-based statistic were used to characterize the impact of white matter pathology on the connectome and its rich club. Significant reductions in FA associated with schizophrenia were widespread, encompassing more than 40% (234ml) of cerebral white matter by volume and involving all cerebral lobes. Significant increases in MD were also widespread and distributed similarly. The corpus callosum, cingulum, and thalamic radiations exhibited the most extensive pathology according to effect size. More than 50% of cortico-cortical and cortico-subcortical white matter fiber bundles comprising the connectome were disrupted in schizophrenia. Connections between hub regions comprising the rich club were disproportionately affected. Pathology did not differ between patients with schizophrenia and schizoaffective disorder and was not mediated by medication. In conclusion, although connectivity between cerebral hubs is most extensively disturbed in schizophrenia, white matter pathology is widespread, affecting all cerebral lobes and the cerebellum, leading to disruptions in the majority of the brain's fiber bundles.

Abstract: BACKGROUND: Polygenic scores (PGSs), which assess the genetic risk of individuals for a disease, are calculated as a weighted count of risk alleles identified in genome-wide association studies. PGS methods differ in which DNA variants are included and the weights assigned to them; some require an independent tuning sample to help inform these choices. PGSs are evaluated in independent target cohorts with known disease status. Variability between target cohorts is observed in applications to real data sets, which could reflect a number of factors, e.g., phenotype definition or technical factors.METHODS: The Psychiatric Genomics Consortium Working Groups for schizophrenia and major depressive disorder bring together many independently collected case-control cohorts. We used these resources (31,328 schizophrenia cases, 41,191 controls; 248,750 major depressive disorder cases, 563,184 controls) in repeated application of leave-one-cohort-out meta-analyses, each used to calculate and evaluate PGS in the left-out (target) cohort. Ten PGS methods (the baseline PC+T method and 9 methods that model genetic architecture more formally: SBLUP, LDpred2-Inf, LDpred-funct, LDpred2, Lassosum, PRS-CS, PRS-CS-auto, SBayesR, MegaPRS) were compared.RESULTS: Compared with PC+T, the other 9 methods gave higher prediction statistics, MegaPRS, LDPred2, and SBayesR significantly so, explaining up to 9.2% variance in liability for schizophrenia across 30 target cohorts, an increase of 44%. For major depressive disorder across 26 target cohorts, these statistics were 3.5% and 59%, respectively.CONCLUSIONS: Although the methods that more formally model genetic architecture have similar performance, MegaPRS, LDpred2, and SBayesR rank highest in most comparisons and are recommended in applications to psychiatric disorders.

Abstract: International audience; Bipolar disorder is a heritable mental illness with complex etiology. We performed a genome-wide association study of 41,917 bipolar disorder cases and 371,549 controls of European ancestry, which identified 64 associated genomic loci. Bipolar disorder risk alleles were enriched in genes in synaptic signaling pathways and brain-expressed genes, particularly those with high specificity of expression in neurons of the prefrontal cortex and hippocampus. Significant signal enrichment was found in genes encoding targets of antipsychotics, calcium channel blockers, antiepileptics and anesthetics. Integrating expression quantitative trait locus data implicated 15 genes robustly linked to bipolar disorder via gene expression, encoding druggable targets such as HTR6, MCHR1, DCLK3 and FURIN. Analyses of bipolar disorder subtypes indicated high but imperfect genetic correlation between bipolar disorder type I and II and identified additional associated loci. Together, these results advance our understanding of the biological etiology of bipolar disorder, identify novel therapeutic leads and prioritize genes for functional follow-up studies.

Abstract: Sex steroids affect cognitive function as well as emotion processing and regulation. They may also play a role in the pathophysiology of schizophrenia. However, the effects of sex steroids on cognition and emotion-related brain activation in schizophrenia are poorly understood. Our aim was to determine the extent to which circulating testosterone relates to brain activation in men with schizophrenia compared to healthy men during cognitive-emotional processing. We assessed brain activation in 18 men with schizophrenia and 22 age-matched healthy men during an emotional go/no-go task using fMRI and measured total serum testosterone levels on the same morning. We performed an ROI analysis to assess the relationship between serum testosterone and brain activation, focusing on cortical regions involved the emotional go/no-go task. Slower RT and reduced accuracy was observed when participants responded to neutral stimuli, while inhibiting responses to negative stimuli. Healthy men showed a robust increase in activation of the middle frontal gyrus when inhibiting responses to negative stimuli, but there was no significant association between activation and serum testosterone level in healthy men. Men with schizophrenia showed a less pronounced increase in activation when inhibiting responses to negative stimuli; however, they did show a strong inverse association between serum testosterone level and activation of the bilateral middle frontal gyrus and left insula. Additionally, increased accuracy during inhibition of response to negative words was associated with both higher serum testosterone levels and decreased activation of the middle frontal gyrus in men with schizophrenia only. We conclude that endogenous hormone levels, even within the normal range, may play an enhanced modulatory role in determining the neural and behavioural response during cognitive-emotional processing in schizophrenia.

A common limitation of neuroimaging studies is their small sample sizes. To overcome this hurdle, the Enhancing Neuro Imaging Genetics through Meta-Analysis (ENIGMA) Consortium combines neuroimaging data from many institutions worldwide. However, this introduces heterogeneity due to different scanning devices and sequences. ENIGMA projects commonly address this heterogeneity with random-effects meta-analysis or mixed-effects mega-analysis. Here we tested whether the batch adjustment method, ComBat, can further reduce site-related heterogeneity and thus increase statistical power. We conducted random-effects meta-analyses, mixed-effects mega-analyses and ComBat mega-analyses to compare cortical thickness, surface area and subcortical volumes between 2897 individuals with a diagnosis of schizophrenia and 3141 healthy controls from 33 sites. Specifically, we compared the imaging data between individuals with schizophrenia and healthy controls, covarying for age and sex. The use of ComBat substantially increased the statistical significance of the findings as compared to random-effects meta-analyses. The findings were more similar when comparing ComBat with mixed-effects mega-analysis, although ComBat still slightly increased the statistical significance. ComBat also showed increased statistical power when we repeated the analyses with fewer sites. Results were nearly identical when we applied the ComBat harmonization separately for cortical thickness, cortical surface area and subcortical volumes. Therefore, we recommend applying the ComBat function to attenuate potential effects of site in ENIGMA projects and other multi-site structural imaging work. We provide easy-to-use functions in R that work even if imaging data are partially missing in some brain regions, and they can be trained with one data set and then applied to another (a requirement for some analyses such as machine learning).

Abstract: A non-clinical sample of male Australian Vietnam veterans, their wives, and adult offspring were interviewed in-person in a national epidemiological study to assess the relationship between the mental ill-health of veterans and the emotional climate of the family while the children were growing up. Veterans were assessed 17 years before their children using standardised psychiatric diagnostic interviews. Family emotional climate was assessed using offspring ratings of parental attachment, and codings of positive and negative family relationship styles based on five minute speech samples provided by the offspring. Sons and daughters had different views of their mothers and fathers, and were less positive towards their fathers particularly if he had posttraumatic stress disorder (PTSD). Veteran PTSD and depression significantly negatively impacted the family emotional climate, while mothers' mental health was not related. Veteran PTSD symptoms were lowest in secure attachment to the veteran and highest in inconsistent attachment for both sons and daughters, but were not related to attachment to the mother. Veteran PTSD was related to daughters' but not sons' perceptions of family emotional climate. The impact of veterans' PTSD on their families' emotional climate is more marked for daughters than sons.

16. Combat, Posttraumatic Stress Disorder, and Smoking Trajectory in a Cohort of Male Australian Army Vietnam Veterans

Abstract: Whether trauma exposure itself or consequent posttraumatic stress disorder (PTSD) is primarily responsible for smoking and failure to quit remains unclear.A cohort of male Australian Vietnam veterans (N = 388) was interviewed twice, 22 and 36 years after their return to Australia using standardized psychiatric diagnostic and health interviews and assessment of combat exposure. The smoking trajectory over time revealed a spectrum of outcomes (never smoked, early quitters, late quitters, and continuing smokers). Analysis used multivariate statistics to assess the relative contributions of combat trauma exposure and PTSD while controlling for potential confounders.The trajectory of smoking over time revealed that 21.9% of veterans had never smoked, 45.1% had quit smoking by the time of wave 1, 16.2% were current smokers at wave 1 who had quit by the time of wave 2, 2.8% were late adopters who were current smokers, and 13.9% were continuing smokers. Smoking was associated in single-predictor models with demographics, intelligence, combat exposure, PTSD symptom clusters and diagnosis, and alcohol disorders. Multivariate analysis revealed that PTSD, combat, and intelligence were related to the smoking spectrum but, after adding demographics and other Axis I psychiatric diagnoses, only combat remained significant. No PTSD symptom cluster uniquely predicted smoking status.The results suggest that trauma exposure in the form of military combat may be a more robust predictor of smoking status over time than PTSD. It may be stress itself, rather than poststress disorder, that is more germane to smoking and failure to quit.Exposure to traumatic stress and development of PTSD have been implicated separately in the maintenance of smoking. This longitudinal cohort study of smoking in war veterans up to three decades postwar enabled evaluation of traumatic stress exposure in combat and the course of PTSD in smoking and quitting while controlling for intelligence, background disadvantage, and other psychiatric conditions. Combat rather than PTSD emerged as more significant to smoking status, suggesting that it may be the traumatic stress itself rather than the development of a poststress disorder that is more germane to smoking in war veterans.

Abstract: Australian male Vietnam veterans (N = 388) were assessed 22 and 36 years after their return to Australia using standardized diagnostic interviews, with added data from Army records and self-report questionnaires. Among veterans who ever had posttraumatic stress disorder (PTSD), 50.3% had a current diagnosis at the second assessment; of those who had a current diagnosis at Wave 1, 46.9% were also current at Wave 2. Late onset occurred for 19.0% of veterans, of whom 60.8% were current at Wave 2. Multivariate analysis compared veterans with no history of PTSD (n = 231) with veterans who had ever had PTSD (n = 157) to assess risk factors for PTSD incidence; and veterans with a history, but not current PTSD (n = 78) with veterans who had current PTSD at the second assessment (n = 79) to assess risk factors for failure to remit. Incidence was associated with lower education, shorter Army training predeployment, higher combat, excess drinking, and help-seeking after return to Australia. Prevalence was associated with having a father who saw combat in World War II, being injured in battle, having a lower intelligence test score, experiencing higher combat, and having a diagnosis of phobia at the first assessment. Only combat was common to incidence and prevalence.

Abstract: Copy number variants (CNVs) have been strongly implicated in the genetic etiology of schizophrenia (SCZ). However, genome-wide investigation of the contribution of CNV to risk has been hampered by limited sample sizes. We sought to address this obstacle by applying a centralized analysis pipeline to a SCZ cohort of 21,094 cases and 20,227 controls. A global enrichment of CNV burden was observed in cases (odds ratio (OR) = 1.11, P = 5.7 x 10(-15)), which persisted after excluding loci implicated in previous studies (OR = 1.07, P = 1.7 x 10(-6)). CNV burden was enriched for genes associated with synaptic function (OR = 1.68, P = 2.8 x 10(-11)) and neurobehavioral phenotypes in mouse (OR = 1.18, P = 7.3 x 10(-5)). Genome-wide significant evidence was obtained for eight loci, including 1q21.1, 2p16.3 (NRXN1), 3q29, 7q11.2, 15q13.3, distal 16p11.2, proximal 16p11.2 and 22q11.2. Suggestive support was found for eight additional candidate susceptibility and protective loci, which consisted predominantly of CNVs mediated by nonallelic homologous recombination.

Abstract: To assess the association between parental post-traumatic stress disorder (PTSD) and offspring PTSD and its specificity for other disorders in a non-clinical epidemiological cohort of Australian Vietnam veterans, their partners and their sons and daughters. Veterans were interviewed twice, in 1992-1994 and 2005-2006; partners were interviewed in 2006-2007, and their offspring in 2012-2014. A total of 125 sons and 168 daughters were interviewed from 197 families, 137 of which also included partners who were the mothers of the children. Statistical analysis used multi-level modelling to compute odds ratios and 95% confidence intervals while controlling for clustering effects within families. Parent PTSD diagnoses were examined for associations with offspring trauma exposure, PTSD and other psychiatric diagnoses. Veteran PTSD increased the risk of PTSD and no other disorder in both sons and daughters; partner PTSD did not. Veteran depression was also a risk factor for sons' PTSD, and alcohol disorder was linked to alcohol dependence in sons and PTSD in daughters, but not when controlling for veteran PTSD. We conclude that PTSD in a Vietnam veteran father increases the risk specifically for PTSD in his sons and daughters.

Abstract: The mechanisms of intergenerational transmission of posttraumatic stress disorder (PTSD) from parent to child are not yet known. We hypothesised that the mechanisms involved in trauma transmission may be dependent upon sex specific caregiver-child dyads and these dyads may have a differential impact on post-traumatic stress disorder (PTSD). A non-clinical sample of adult offspring (N = 306) of Australian Vietnam veterans was interviewed in-person to assess the relationship between family emotional climate and caregiver attachment with the offspring's adult experience of post-traumatic stress disorder (PTSD). Attachment to the veteran father was not associated with sons’ PTSD, but was for daughters. Attachment to mother was associated with PTSD and depression for both sons and daughters, with positive and warm attachment related to reduced PTSD diagnosis and its symptom clusters. A less positive family emotional environment was related to increased PTSD symptoms in daughters, while for sons a negative relationship style with their mother was related to increased frequency and severity of numbing/avoidance behaviours and hyperarousal symptoms. The findings suggest that sex-related differences in caregiver-child dyads do have a differential impact on PTSD symptom domains and may be one environmental mechanism by which trauma is transmitted across generations.

Abstract: Evidence suggests that anomalous mismatch negativity (MMN) in schizophrenia is related to glutamatergic abnormalities, possibly involving N-methyl-d-aspartate (NMDA) receptors. Decreased cortical expressions of NMDA receptor subunits have been observed in schizophrenia, though not consistently. To aid with integration and interpretation of previous work, we performed a meta-analysis of effect sizes of mRNA or protein levels of the obligatory NR1 subunit in prefrontal cortex from people with schizophrenia. In schizophrenia compared to unaffected controls the pooled effect size was −0.64 (95% confidence interval: −1.08 to −0.20) for NR1 mRNA reduction and −0.44 (95% confidence interval: −0.80 to −0.07) for NR1 protein reduction. These results represent the first step to a deeper understanding of the region-specific, cell-specific, and stage-specific NMDA receptor hypofunction in schizophrenia, which could be linked to mismatch negativity deficits via transgenic and pharmacological animal models.

Abstract: War service increases the risk of post-traumatic stress disorder (PTSD) to combatants, and has been shown to increase the risk of PTSD in their offspring. The extent to which there is an excess compared with the general population is not yet established, nor whether PTSD increases the risk of other psychiatric problems. A national sample of 133 sons and 182 daughters of a cohort of 179 Australian Vietnam veterans' families were assessed in person, using structured psychiatric interviews. The prevalence of trauma exposures, DSM-IV (Diagnostic and Statistical Manual of Mental Disorders Fourth Edition) diagnoses and suicidality were compared with the Australian Bureau of Statistics' 2007 National Survey of Mental Health and Wellbeing data matched for age and sex. The risk of mental health problems potentially attributable to PTSD was also assessed. Sons and daughters were more likely than population expectations to report exposures to natural disasters, fire or explosions and transport accidents, and sons more likely to report exposure to toxic chemicals whereas daughters were more likely to report sexual assault. Sons and daughters had higher prevalences of alcohol and other substance dependence, depression and anxiety, and PTSD, and children's PTSD was associated with substance dependence, depression and suicidal ideation. There were strong associations between children's PTSD and comorbid conditions of substance use disorders, depression and anxiety. Higher rates of mental health problems in veterans' families, together with comorbidity with PTSD and the link between veterans' and children's PTSD, suggest that the effects of trauma may continue into subsequent generations.

Abstract: Growing evidence suggests that testosterone may play a role in the pathophysiology of schizophrenia given that testosterone has been linked to cognition and negative symptoms in schizophrenia. Here, we determine the extent to which serum testosterone levels are related to neural activity in affective processing circuitry in men with schizophrenia. Functional magnetic resonance imaging was used to measure blood-oxygen-level-dependent signal changes as 32 healthy controls and 26 people with schizophrenia performed a facial emotion identification task. Whole brain analyses were performed to determine regions of differential activity between groups during processing of angry versus non-threatening faces. A follow-up ROI analysis using a regression model in a subset of 16 healthy men and 16 men with schizophrenia was used to determine the extent to which serum testosterone levels were related to neural activity. Healthy controls displayed significantly greater activation than people with schizophrenia in the left inferior frontal gyrus (IFG). There was no significant difference in circulating testosterone levels between healthy men and men with schizophrenia. Regression analyses between activation in the IFG and circulating testosterone levels revealed a significant positive correlation in men with schizophrenia (r=.63, p=.01) and no significant relationship in healthy men. This study provides the first evidence that circulating serum testosterone levels are related to IFG activation during emotion face processing in men with schizophrenia but not in healthy men, which suggests that testosterone levels modulate neural processes relevant to facial emotion processing that may interfere with social functioning in men with schizophrenia.

Abstract: There is increasing clinical and molecular evidence for the role of hormones and specifically estrogen and its receptor in schizophrenia. A selective estrogen receptor modulator, raloxifene, stimulates estrogen-like activity in brain and can improve cognition in older adults. The present study tested the extent to which adjunctive raloxifene treatment improved cognition and reduced symptoms in young to middle-age men and women with schizophrenia. Ninety-eight patients with a diagnosis of schizophrenia or schizoaffective disorder were recruited into a dual-site, thirteen-week, randomized, double-blind, placebo-controlled, crossover trial of adjunctive raloxifene treatment in addition to their usual antipsychotic medications. Symptom severity and cognition in the domains of working memory, attention/processing speed, language and verbal memory were assessed at baseline, 6 and 13 weeks. Analyses of the initial 6-week phase of the study using a parallel groups design (with 39 patients receiving placebo and 40 receiving raloxifene) revealed that participants receiving adjunctive raloxifene treatment showed significant improvement relative to placebo in memory and attention/processing speed. There was no reduction in symptom severity with treatment compared with placebo. There were significant carryover effects, suggesting some cognitive benefits are sustained even after raloxifene withdrawal. Analysis of the 13-week crossover data revealed significant improvement with raloxifene only in attention/processing speed. This is the first study to show that daily, oral adjunctive raloxifene treatment at 120 mg per day has beneficial effects on attention/processing speed and memory for both men and women with schizophrenia. Thus, raloxifene may be useful as an adjunctive treatment for cognitive deficits associated with schizophrenia.

Abstract: Polygenic risk scores have shown great promise in predicting complex disease risk and will become more accurate as training sample sizes increase. The standard approach for calculating risk scores involves linkage disequilibrium (LD)-based marker pruning and applying a p value threshold to association statistics, but this discards information and can reduce predictive accuracy. We introduce LDpred, a method that infers the posterior mean effect size of each marker by using a prior on effect sizes and LD information from an external reference panel. Theory and simulations show that LDpred outperforms the approach of pruning followed by thresholding, particularly at large sample sizes. Accordingly, predicted R-2 increased from 20.1% to 25.3% in a large schizophrenia dataset and from 9.8% to 12.0% in a large multiple sclerosis dataset. A similar relative improvement in accuracy was observed for three additional large disease datasets and for non-European schizophrenia samples. The advantage of LDpred over existing methods will grow as sample sizes increase. Refereed/Peer-reviewed

Abstract: J. Lönnqvist on työryhmän Psychiat Genomics Consortium jäsen. Genetic correlation is a key population parameter that describes the shared genetic architecture of complex traits and diseases. It can be estimated by current state-of-art methods, i.e., linkage disequilibrium score regression (LDSC) and genomic restricted maximum likelihood (GREML). The massively reduced computing burden of LDSC compared to GREML makes it an attractive tool, although the accuracy (i.e., magnitude of standard errors) of LDSC estimates has not been thoroughly studied. In simulation, we show that the accuracy of GREML is generally higher than that of LDSC. When there is genetic heterogeneity between the actual sample and reference data from which LD scores are estimated, the accuracy of LDSC decreases further. In real data analyses estimating the genetic correlation between schizophrenia (SCZ) and body mass index, we show that GREML estimates based on similar to 150,000 individuals give a higher accuracy than LDSC estimates based on similar to 400,000 individuals (from combinedmeta-data). A GREML genomic partitioning analysis reveals that the genetic correlation between SCZ and height is significantly negative for regulatory regions, which whole genome or LDSC approach has less power to detect. We conclude that LDSC estimates should be carefully interpreted as there can be uncertainty about homogeneity among combined meta-datasets. We suggest that any interesting findings from massive LDSC analysis for a large number of complex traits should be followed up, where possible, with more detailed analyses with GREML methods, even if sample sizes are lesser.

Abstract: Publisher's version (útgefin grein), Previous studies have shown an increased risk for mental health problems in children born to both younger and older parents compared to children of average-aged parents. We previously used a novel design to reveal a latent mechanism of genetic association between schizophrenia and age at first birth in women (AFB). Here, we use independent data from the UK Biobank (N = 38,892) to replicate the finding of an association between predicted genetic risk of schizophrenia and AFB in women, and to estimate the genetic correlation between schizophrenia and AFB in women stratified into younger and older groups. We find evidence for an association between predicted genetic risk of schizophrenia and AFB in women (P-value = 1.12E-05), and we show genetic heterogeneity between younger and older AFB groups (P-value = 3.45E-03). The genetic correlation between schizophrenia and AFB in the younger AFB group is −0.16 (SE = 0.04) while that between schizophrenia and AFB in the older AFB group is 0.14 (SE = 0.08). Our results suggest that early, and perhaps also late, age at first birth in women is associated with increased genetic risk for schizophrenia in the UK Biobank sample. These findings contribute new insights into factors contributing to the complex bio-social risk architecture underpinning the association between parental age and offspring mental health., This research is supported by the Australian National Health and Medical Research Council (1080157, 1087889, 1103418, 1127440), and the Australian Research Council (DP160102126, FT160100229).

Abstract: Objective: In response to evidence of deteriorating outcomes of people with schizophrenia we recently published a critical review in the journal concerning why outcomes for schizophrenia are not improving. A published commentary on our review raised criticisms that we aim to address herein. Method: Published data related to four issues raised in the commentary were reviewed. Results: There is a body of evidence that supports the possibility of dramatic improvements in treatment effectiveness, presented in our critical review, and these can be achieved within existing financial resources and present day understanding of the pathophysiology of schizophrenia. However, the commentary leads us to highlight four current obstacles to improving treatment effectiveness: (1) the belief of many psychiatrists that long-term antipsychotic medication raises the cardiovascular mortality rate in schizophrenia when the opposite is almost certainly the case; (2) the need to improve psychiatrist training in diagnostic and communication skills, especially with first episode presentations; (3) the requirement for comprehensive and structured assessment of the highly prevalent deficits in insight and decision making capacity associated with schizophrenia; and (4) the need for improved intervention design to minimise the impact of these deficits on treatment choice and refusal. Conclusion: With a sense of professional urgency, a genuinely respectful and caring partnership between clinicians, affected individuals and their families, and researchers, with relative little innovation, we conclude that the standard of care can definitely be raised now in the treatment of schizophrenia.

Abstract: We have previously shown higher-than-expected rates of schizophrenia in relatives of patients with amyotrophic lateral sclerosis (ALS), suggesting an aetiological relationship between the diseases. Here, we investigate the genetic relationship between ALS and schizophrenia using genome-wide association study data from over 100,000 unique individuals. Using linkage disequilibrium score regression, we estimate the genetic correlation between ALS and schizophrenia to be 14.3% (7.05–21.6; P=1 × 10−4) with schizophrenia polygenic risk scores explaining up to 0.12% of the variance in ALS (P=8.4 × 10−7). A modest increase in comorbidity of ALS and schizophrenia is expected given these findings (odds ratio 1.08–1.26) but this would require very large studies to observe epidemiologically. We identify five potential novel ALS-associated loci using conditional false discovery rate analysis. It is likely that shared neurobiological mechanisms between these two disorders will engender novel hypotheses in future preclinical and clinical studies., Relatives of patients with amyotrophic lateral sclerosis have an unexpectedly high incidence of schizophrenia. Here, the authors show a genetic link between the two conditions, suggesting shared neurobiological mechanisms.

Abstract: Contains fulltext : 193179.pdf (Publisher’s version ) (Open Access) The regional distribution of white matter (WM) abnormalities in schizophrenia remains poorly understood, and reported disease effects on the brain vary widely between studies. In an effort to identify commonalities across studies, we perform what we believe is the first ever large-scale coordinated study of WM microstructural differences in schizophrenia. Our analysis consisted of 2359 healthy controls and 1963 schizophrenia patients from 29 independent international studies; we harmonized the processing and statistical analyses of diffusion tensor imaging (DTI) data across sites and meta-analyzed effects across studies. Significant reductions in fractional anisotropy (FA) in schizophrenia patients were widespread, and detected in 20 of 25 regions of interest within a WM skeleton representing all major WM fasciculi. Effect sizes varied by region, peaking at (d=0.42) for the entire WM skeleton, driven more by peripheral areas as opposed to the core WM where regions of interest were defined. The anterior corona radiata (d=0.40) and corpus callosum (d=0.39), specifically its body (d=0.39) and genu (d=0.37), showed greatest effects. Significant decreases, to lesser degrees, were observed in almost all regions analyzed. Larger effect sizes were observed for FA than diffusivity measures; significantly higher mean and radial diffusivity was observed for schizophrenia patients compared with controls. No significant effects of age at onset of schizophrenia or medication dosage were detected. As the largest coordinated analysis of WM differences in a psychiatric disorder to date, the present study provides a robust profile of widespread WM abnormalities in schizophrenia patients worldwide. Interactive three-dimensional visualization of the results is available at www.enigma-viewer.org.

32. The treatment of schizophrenia: Can we raise the standard of care?

Abstract: Objective: There is evidence that over time health outcomes of people with schizophrenia are deteriorating rather than improving both in terms of mortality rate and levels of morbidity, even in Australia where service resourcing is substantial. Our objective was to examine the evidence of whether poor outcomes reflect decreases in treatment effectiveness and, if so, what are the barriers to improving standards of care. This review will argue that the confidence of clinicians to diagnose schizophrenia early, and provide assertive and long-term care, may be being undermined by a series of controversies in the published literature and discrepancies in clinical practice guidelines. Method: A critical review was conducted of the evidence regarding six issues of high clinical relevance to the treatment of schizophrenia formulated as questions: (1) Is schizophrenia a progressive disease? (2) Does relapse contribute to disease progression and treatment resistance? (3) When should the diagnosis of schizophrenia be made? (4) Should maintenance antipsychotic medication be discontinued in fully remitted first-episode patients? (5) Do antipsychotic medications cause deleterious reductions in cortical grey matter volumes? and (6) Are long-acting injectable antipsychotics more effective in reducing relapse rate compared to oral formulations? Results: There is reliable evidence for schizophrenia being a progressive disease with emergent treatment resistance in most cases, that relapse contributes to this treatment resistance, that maintenance antipsychotic medication should not be discontinued in remitted first-episode patients, that antipsychotic medication does not appear to cause deleterious grey matter volume changes, that maintenance antipsychotic medication reduces the mortality rate in schizophrenia and that long-acting injectable antipsychotics are more effective in preventing relapse than oral formulations. Conclusion: There is an urgent need to re-engineer the early management of schizophrenia and to routinely evaluate this type of innovation within practice-based research networks. A proposal for an assertive treatment algorithm is included.

Abstract: Patients with delusions typically seek less information when making decisions than controls ("jumping-to-conclusions", JTC) and paradoxically over-adjust to counter-evidence on probabilistic reasoning tasks. Previous studies have examined JTC bias across the delusion-prone continuum, but have not considered the co-occurrence of both biases at early stages of psychosis. This was our aim.Twenty-three early psychosis patients and 19 healthy controls completed two versions of the probabilistic reasoning task: a "draws-to-decision" version (to assess JTC) and a "graded-estimates" version (to assess over-adjustment). Both versions have been used previously with clinically delusional people with schizophrenia. IQ, memory and executive function were also examined.Patients took fewer trials to reach a decision in the draws-to-decision version and showed greater over-adjustment to counter-evidence in the graded-estimates version than controls. Across groups, those who jumped to conclusions showed greater over-adjustment. Poor executive function predicted more extreme biases in controls but not in patients. Task performances were unrelated to memory. Similar results were evident in patient and control subgroups matched on IQ, and years of formal education.A jumping-to-conclusions bias and an over-adjustment bias co-occurred in the early psychosis patients. Implications are discussed concerning the role of such biases in delusion-proneness.

Abstract: Attributional biases to externalize blame for negative events (externalizing bias) and to target other people for blame (personalizing bias) may constitute a vulnerability to psychosis. However, most research to date has only examined attributional biases in chronic patients. We examined attributional style, paranoia, and depression in early psychosis patients to assess the primacy of attributional biases in psychosis.A quasi-experimental design was adopted to compare the attributional style of patients and controls. Correlates of attributional style were also examined.Early psychosis patients and age- and gender-matched healthy controls completed the 'Internal, Personal and Situational Attributions Questionnaire'. Paranoid tendencies, suspiciousness, and depression were also assessed in both groups, while severity of current symptoms was assessed in patients.A high proportion of patients had persecutory delusions. These patients, however, did not differ from controls in externalizing or personalizing bias. Whereas suspiciousness and persecutory delusions in patients associated with externalizing bias, no bias measures associated with paranoid tendencies in either patients or controls. Counter to the pattern seen for endogenous depression, depression in patients was associated with an increased tendency to attribute events to self and a decreased tendency to attribute events to circumstances.These preliminary findings raise doubts about the primacy of attributional biases in psychosis. The novel findings with regard to depression warrant further investigation and suggest that young people, who develop depression after the onset of psychosis, may experience a need to re-establish a sense of personal control over life events that appear unpredictable.

Abstract: Aim: A deficit in theory of mind - the ability to infer and reason about the mental states of others - might underpin the poor social functioning of patients with psychosis. Unfortunately, however, there is considerable variation in how such a deficit is assessed. The current study compared three classic tests of theory of mind in terms of their ability to detect impairment in patients in the early stages of psychosis.

Abstract: It is well established that individuals with schizophrenia demonstrate alterations in auditory perception beginning at the very earliest stages of information processing. However, it is not clear how these impairments in basic information processing translate into high-order cognitive deficits. Auditory scene analysis allows listeners to group auditory information into meaningful objects, and as such provides an important link between low-level auditory processing and higher cognitive abilities. In the present study we investigated whether low-level impairments in the processing of binaural temporal information impact upon auditory scene analysis ability. Binaural temporal processing ability was investigated in 19 individuals with schizophrenia and 19 matched controls. Individuals with schizophrenia showed impaired binaural temporal processing ability on an inter-aural time difference (ITD) discrimination task. In addition, patients demonstrated impairment in two measures of auditory scene analysis. Specifically, patients had reduced ability to use binaural temporal cues to extract signal from noise in a masking level difference paradigm, and to separate the location of a source sound in the presence of an echo in the precedence effect paradigm. These findings demonstrate that individuals with schizophrenia have impairments in the accuracy with which simple binaural temporal information is encoded in the auditory system, and furthermore, this impairment has functional consequences in terms of the use of these cues to extract information in complex auditory environments.

Abstract: Australian male Vietnam veterans (N = 388) were assessed 22 and 36 years after their return to Australia using standardized diagnostic interviews, with added data from Army records and self-report questionnaires. Among veterans who ever had posttraumatic stress disorder (PTSD), 50.3% had a current diagnosis at the second assessment; of those who had a current diagnosis at Wave 1, 46.9% were also current at Wave 2. Late onset occurred for 19.0% of veterans, of whom 60.8% were current at Wave 2. Multivariate analysis compared veterans with no history of PTSD (n = 231) with veterans who had ever had PTSD (n = 157) to assess risk factors for PTSD incidence; and veterans with a history, but not current PTSD (n = 78) with veterans who had current PTSD at the second assessment (n = 79) to assess risk factors for failure to remit. Incidence was associated with lower education, shorter Army training predeployment, higher combat, excess drinking, and help-seeking after return to Australia. Prevalence was associated with having a father who saw combat in World War II, being injured in battle, having a lower intelligence test score, experiencing higher combat, and having a diagnosis of phobia at the first assessment. Only combat was common to incidence and prevalence.

Abstract: Genomic copy number variants (CNVs) have been strongly implicated in the etiology of schizophrenia (SCZ). However, apart from a small number of risk variants, elucidation of the CNV contribution to risk has been difficult due to the rarity of risk alleles, all occurring in less than 1% of cases. We sought to address this obstacle through a collaborative effort in which we applied a centralized analysis pipeline to a SCZ cohort of 21,094 cases and 20,227 controls. We observed a global enrichment of CNV burden in cases (OR=1.11, P=5.7e −15 ), which persisted after excluding loci implicated in previous studies (OR=1.07, P=1.7e −6 ). CNV burden is also enriched for genes associated with synaptic function (OR = 1.68, P = 2.8e −11 ) and neurobehavioral phenotypes in mouse (OR = 1.18, P=7.3e −5 ). We identified genome-wide significant support for eight loci, including 1q21.1, 2p16.3 (NRXN1), 3q29, 7q11.2, 15q13.3, distal 16p11.2, proximal 16p11.2 and 22q11.2. We find support at a suggestive level for nine additional candidate susceptibility and protective loci, which consist predominantly of CNVs mediated by non-allelic homologous recombination (NAHR).

Abstract: Blockade of N-methyl-D-aspartate receptors (NMDARs) produces behavior in healthy people that is similar to the psychotic symptoms and cognitive deficits of schizophrenia and can exacerbate symptoms in people with schizophrenia. However, an endogenous brain disruption of NMDARs has not been clearly established in schizophrenia. We measured mRNA transcripts for five NMDAR subunit mRNAs and protein for the NR1 subunit in the dorsolateral prefrontal cortex (DLPFC) of schizophrenia and control (n=74) brains. Five NMDAR single-nucleotide polymorphisms (SNPs) previously associated with schizophrenia were tested for association with NMDAR mRNAs in postmortem brain and for association with cognitive ability in an antemortem cohort of 101 healthy controls and 48 people with schizophrenia. The NR1 subunit (mRNA and protein) and NR2C mRNA were decreased in postmortem brain from people with schizophrenia (P=0.004, P=0.01 and P=0.01, respectively). In the antemortem cohort, the minor allele of NR2B rs1805502 (T5988C) was associated with significantly lower reasoning ability in schizophrenia. In the postmortem brain, the NR2B rs1805502 (T5988C) C allele was associated with reduced expression of NR1 mRNA and protein in schizophrenia. Reduction in NR1 and NR2C in the DLPFC of people with schizophrenia may lead to altered NMDAR stoichiometry and provides compelling evidence for an endogenous NMDAR deficit in schizophrenia. Genetic variation in the NR2B gene predicts reduced levels of the obligatory NR1 subunit, suggesting a novel mechanism by which the NR2B SNP may negatively influence other NMDAR subunit expression and reasoning ability in schizophrenia.

Abstract: Cancer incidence in schizophrenia is not increased commensurate with higher rates of risk exposures. Here we report an investigation of the DNA damage response, an anti-tumorigenic defence, in immortalised lymphoblasts from patients with schizophrenia.Unirradiated and irradiated (5Gy) lymphoblasts from schizophrenia patients (n = 28) and healthy controls (n = 28) were immunostained for the phosphorylated histone variant H2AX (γH2AX), an index of DNA double-strand breaks. Flow cytometry was used to assess cell cycle distribution and γH2AX immunofluorescence. Rate of DNA repair was quantified by determining the temporal change in γH2AX values following irradiation.In unirradiated lymphoblasts, γH2AX levels were significantly increased in the schizophrenia group compared with controls (effect size = 0.86). This increase was most evident in patients with cognitive deficits. In irradiated lymphoblasts, peak radiation-induced γH2AX levels were significantly reduced in patients. No differences between patients and controls were found in the rate of DNA repair or in cell cycle distribution.The significant differences in DNA damage response signalling observed involve modification of histone variant H2AX and thereby implicate regulatory processes determining chromatin structure in dividing lymphoblasts from patients with schizophrenia. The role that aberrant DNA damage response signalling plays in protecting patients from cancer is unclear.

Abstract: Aim: Clinical practice improvement carried out in a quality assurance framework relies on routinely collected data using clinical indicators. Herein we describe the development, minimum training requirements, and inter-rater agreement of indicators that were used in an Australian multi-site evaluation of the effectiveness of early psychosis (EP) teams. Methods: Surveys of clinician opinion and face-to-face consensus-building meetings were used to select and conceptually define indicators. Operationalization of definitions was achieved by iterative refinement until clinicians could be quickly trained to code indicators reliably. Calculation of percentage agreement with expert consensus coding was based on ratings of paper-based clinical vignettes embedded in a 2-h clinician training package. Results: Consensually agreed upon conceptual definitions for seven clinical indicators judged most relevant to evaluating EP teams were operationalized for ease-of-training. Brief training enabled typical clinicians to code indicators with acceptable percentage agreement (60% to 86%). For indicators of suicide risk, psychosocial function, and family functioning this level of agreement was only possible with less precise ‘broad range’ expert consensus scores. Estimated kappa values indicated fair to good inter-rater reliability (kappa > 0.65). Inspection of contingency tables (coding category by health service) and modal scores across services suggested consistent, unbiased coding across services. Conclusions: Clinicians are able to agree upon what information is essential to routinely evaluate clinical practice. Simple indicators of this information can be designed and coding rules can be reliably applied to written vignettes after brief training. The real world feasibility of the indicators remains to be tested in field trials.

Abstract: AIM: Expert opinion holds that the rate of implementation of specialist services for first presentation psychosis in Australia is much too slow. We aimed to collect evidence regarding this view from the first national survey of adult public mental health services about their self-reported efforts to implement specialist early psychosis intervention (EPI). METHODS: Using a purpose-designed Census form for assessing EPI implementation, adult public mental health service directors throughout Australia were asked about EPI-relevant local service activities. RESULTS: Sixty Census forms were returned (response rate = 61%), representing a total catchment population of 12.5 million people. A minority of services reported high levels of EPI implementation, which varied widely between area services and across state and territory jurisdictions. Rural and remote services were overrepresented in the lowest levels of reported EPI implementation. Only one service characteristic, the value of identifiable funding committed specifically to EPI, was predictive of level of reported EPI implementation. CONCLUSIONS: The disturbingly high levels of variability in EPI implementation across jurisdictions suggest a pressing need for a set of nationally agreed uniform EPI implementation standards. Additional specific strategies for rural and remote mental health services may be needed for these services to implement EPI.

Abstract: The reported reduction in cancer risk in those suffering from schizophrenia may be because antipsychotic medications have antineoplastic effects. In this study, 6 antipsychotic agents with a range of structural and pharmacological properties (reserpine, chlorpromazine, haloperidol, pimozide, risperidone and olanzapine), were screened for their effect on the viability of cell lines derived from lymphoblastoma, neuroblastoma, non-small cell lung cancer and breast adenocarcinoma. We aimed to determine if antipsychotic drugs in general possess cancer-specific cytotoxic potential, and whether it can be attributed to a common mode of action. With the exception of risperidone, all drugs tested displayed selective inhibition of the viability of cancer cell lines compared with normal cells. Using Affymetrix expression microarrays and quantitative real-time polymerase chain reaction, we found that for the antipsychotic drugs, olanzapine and pimozide, cytotoxicity appeared to be mediated via effects on cholesterol homeostasis. The role of cholesterol metabolism in the selective cytotoxicity of these drugs was supported by demonstration of their increased lethality when coadministered with a cholesterol synthesis inhibitor, mevastatin. Also, pimozide and olanzapine showed accelerating cytotoxic effects from 12 to 48 hr in time course studies, mirroring the time-dependent onset of cytotoxicity induced by the amphiphile, U18666A. On the basis of these results, we concluded that the Class II cationic amphiphilic properties of antipsychotic drugs contribute to their cytotoxic effects by acting on cholesterol homeostasis and altering the biophysical properties of cellular membranes, and that drugs affecting membrane-related cholesterol pathways warrant further investigation as potential augmentors of standard cancer chemotherapy.

Abstract: Background: Compared with other leading public health probems, research capacity for schizophrenia and bipolar disorder is grossly under-developed. Also, there are unacceptible delays in applying research discovery to routine clinical practice. Stakeholders have expressed concern with the apparent lack of effect of research upon clinical outcomes. Methods: Interdisciplinary consensus-building processes were supported in order to draft a national psychosis research strategy. Review of the management literature was undertaken to identify an appropriate organisational structure within which to implement the strategy. Results: A translational research framework which linked epidemiological, genetic, neuroscience and drug design research to the development of novel therapeutics and clinical pratice improvement was the preferred research program option and a national collaborative structured network was deemed the optimal governance model. Conclusion: Australia is well-positioned to make a world-leading contribution to finding ways to prevent and cure schizophrenia and bipolar disorder but only with new sources of recurrent funding in the order of $20 million annually.

Abstract: Introduction: This paper reports on the development of a national recruitment and clinical assessment strategy by the Australian Schizophrenia Research Bank (ASRB). The aim of this strategy is to ensure a representative sample of people with schizophrenia and to collect comprehensive, cross-referenced clinical, cognitive, genetic, brain imaging and linked data. Method: The ASRB recruitment targets are 2000 people with schizophrenia and 2000 healthy, non-psychiatric controls. Using a three pronged approach, schizophrenia subjects will be recruited from various settings. To recruit people in the community, a successful TV and radio community service advertisement campaign was developed and a national 1800 telephone number established. The assessment battery includes the Diagnostic Interview for Psychosis (DIP: Castle et al, 2005), Neurological Evaluation Scale (Buchanan & Heinrichs, 1989), Wechsler Test of Adult Reading (WTAR-Wechsler, 2001), Wechsler Abbreviated Scale of Intelligence (WASI-Wechsler, 1999), Repeatable Battery for Assessment of Neuropsychological Status (RBANS Randolph et al, 1998), Letter Number Sequencing (Wechsler, 1997), Controlled Oral Word Association Test (Spreen & Benton, 1969), Global Assessment of Functioning (GAF-American Psychiatric Association, 2000), and the Schizotypal Personality Questionnaire (Raine et al., 1991). In addition, a blood sample and structural MRI scan are collected. Results: Over 2000 people have registered with the ASRB using the 1800 number. A proportion of these people have been assessed using the ASRB assessment battery. Conclusion: The ASRB is the first Australian research facility to develop a national recruitment and clinical assessment strategy in schizophrenia.

Abstract: Introduction: Whilst there is robust evidence of excess medical comorbidity in patients with schizophrenia, there are conflicting findings concerning cancer incidence rates in this population.Aim: To carry out a meta-analysis of published studies on the cancer incidence in patients with schizophrenia and their first degree relatives.Method: Meta-analysis was performed on standardised incidence ratios (SIR) of cancer in patients with schizophrenia and first degree relatives compared to general population samples.Results: The pooled overall cancer incidence in patients was notsignificantly increased (SIR1.05, CI 0.951.15). Lung cancer incidence was slightly increased (SIR1.31, CI 1.011.71), but it was reduced after adjusting for smoking prevalence. The incidence of several cancers unrelated to smoking was reduced in patients. The pooled overall cancer incidence in siblings (SIR0.89, CI 0.840.94) and parents (SIR0.90, CI 0.880.93) was significantly reduced.Conclusions: There is direct evidence of a discrepancy between cancer risk exposure and cancer incidence in patients with schizophrenia, and indirect evidence that this discrepancy is unlikely to result from confounding effects of medication or lower detection rates in patients.

Abstract: The purpose of the present study was to determine antipsychotic doses that achieve 80% striatal dopamine D2-receptor occupancy for haloperidol, risperidone and olanzapine in rats. Wistar rats were treated with normal saline vehicle (controls), haloperidol (0.25 and 0.5 mg/kg/day), risperidone (3, 5 and 6 mg/kg/day) and olanzapine (5 and 10 mg/kg/day) for 7 days via osmotic minipumps. Striatal and cerebellar tissue were collected and in vivo dopamine D2-receptor occupancies were determined using 3H-raclopride. The doses required to achieve dopamine D2-receptor occupancy of 80% in 11- and 24-week old rats were: haloperidol 0.25 mg/kg/day, risperidone 5 mg/kg/day and olanzapine 10 mg/kg/day.

Abstract: The mentalising abilities of schizophrenic patients and normal controls were tested using picture sequencing and story-telling tasks that required subjects to infer causal mental states in story characters, and a recall task that required subjects to dissociate subjective mental states from objective realities. Selective mentalising deficits were found in some patients. For other patients, general sequencing errors, "sensory" mentalising, and poor recall of symbolic representations suggested more profound problems. Task results were best accounted for by dissociable cognitive abnormalities, rather than graded dysfunction of a central mentalising mechanism. Symptom profiles of patient subgroups and correlations between task measures and clinical ratings linked these cognitive abnormalities to specific symptoms. General sequencing difficulty was associated with both poverty symptoms and reality distortion, suggesting that two mechanisms may underpin such errors: one, inability to manipulate symbolic representations, being linked to poverty; the other, failure to critically evaluate plausible cause-and-effect, being linked to reality distortion. There was some evidence that defective self-monitoring underpins thought disorder. Impaired metarepresentation was linked to the autisticlike symptoms of flat affect, social dysfunction, and alogia, rather than reality distortion. Implications of these findings are discussed with respect to theoretical and methodological issues confronting current schizophrenia research.
