- Objective: Based on the well-documented association between eating disorders (EDs) and affective disorders, the patterns of comorbidity of EDs and major depressive disorder (MDD) were investigated. The temporal relation between EDs and MDD onset was analyzed to determine differences in the course and nature of MDD when experienced prior to versus after the onset of the ED. Method: Lifetime MDD and depressive symptoms were assessed in 1371 women with a history of ED. The prevalence of MDD was first explored across ED subtypes, and ages of onset of MDD and EDs were compared. Depressive symptoms were examined in individuals who developed MDD before and after ED onset. Results: The lifetime prevalence of MDD was 72.9%. Among those with lifetime MDD (n =963), 34.5% reported MDD onset before the onset of ED. Those who experienced MDD first reported greater psychomotor agitation (OR =1.53; 95%CI =1.14–2.06), and thoughts of own death (but not suicide attempts or ideation; OR =1.73; 95%CI =1.31–2.30). Among individuals who had MDD before ED, 26.5% had the MDD onset during the year before the onset of ED; 67% of individuals had the onset of both disorders within the same 3 year window. Conclusion: Clinicians treating individuals with new-onset ED or MDD should remain vigilant for the emergence of additional psychopathology, especially during the initial 3 year window following the onset of the first disorder.

- Objective: Previous research has shown conflicting results for the significance of five v-akt murine thymoma viral oncogene homolog 1 ( AKT1) single-nucleotide polymorphisms (SNPs) to the aetiology of schizophrenia. Neurocognition is a plausible endophenotype for schizophrenia and it was reasoned that the lack of agreement might be due to variability in neurocognition across studies. Therefore, the association of genetic variation in AKT1 with neurocognition was investigated in patients with schizophrenia. Methods: The same five SNPs used in previous studies of the etiology of schizophrenia (rs2494732, rs2498799, rs3730358, rs1130241, and rs3803300) were genotyped in 641 individuals with schizophrenia who had participated in the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) project. The primary dependent variable was a neurocognitive composite score and exploratory analyses investigated five domain scores (processing speed, reasoning, verbal memory, working memory, and vigilance). Results: There were no significant asymptotic or empirical associations between any SNP and the neurocognitive composite score. The authors also investigated the association of five-SNP haplotypes with the neurocognitive composite score. A marginally significant association was observed for the neurocognitive composite score with one of the five-SNP haplotypes (global score statistic 19.51, df = 9, permutation p = 0.02). Exploratory analyses of five domain scores (processing speed, reasoning, verbal memory, working memory, and vigilance) were non-significant for all five SNPs. Conclusion: Results published to date for an association between genetic variation in AKT1 with schizophrenia are inconsistent. The results suggest that the AKT1 markers studied are not associated with neurocognition in schizophrenia, and do not support unassessed variation in neurocognitive scores as a reason for this discrepancy.

- Objective: To compare patterns of recovery in individuals with index episodes of anorexia nervosa (AN) and bulimia nervosa (BN). Method: Using Kaplan–Meier methods and Cox proportional hazards models, comparisons were conducted that were conditional on duration of eating disorder from onset and included a conservative recovery criterion of 3 asymptomatic years. Data collection was retrospective and from two of the international Price Foundation genetic studies on 901 individuals with eating disorders. Results: Using Kaplan–Meier methods, 11% of those with index AN and 10% of those with index BN met recovery criteria at 10 years. At 15 years, 16% of those with index AN and 25% of those with index BN met recovery criteria. In a Cox proportional hazards model the index BN group had three times the rate of recovery at 10–14 years (p=0.01) than the index AN group. Conclusions: Initially the probability of recovery was greater for those with index AN, but as the duration of the eating disorder lengthened those with BN had higher probabilities of recovery. Replication of these results with prospective data using similarly stringent recovery criteria and methods is required to confirm trends.
