Abstract
BACKGROUND Although bereavement is accompanied with depression and anxiety symptoms, it is usually not associated with increased rates of mental disorders in North American and European samples. Data from low- and middle-income countries are, however, scarce. We therefore explored the prevalence of mental disorders after bereavement in Brazil. METHODS The Clinical Interview Schedule-Revised (CIS-R) was used for psychiatric assessment of 15,105 participants from the Brazilian Health Longitudinal Study (ELSA-Brasil). We asked whether the participant suffered loss of a first-degree relative/spouse within 6 and 12 months prior to the interview. RESULTS The prevalence within 6 and 12 months after bereavement for major depressive disorder (MDD, 4.3% for 6 and 12 months) and anxiety disorders (17.4% and 15.9%, respectively) did not differ compared to non-bereaved participants, except for panic disorder. Sociodemographic and clinical data were also similar. Conversely, we found increased 12-month prevalence of bereaved-related (vs. non-related) mixed anxiety and depressive disorder (15.7% vs. 12.5%, respectively) and common mental disorder (30.7% vs. 26.2%); diagnoses that are solely based on the number and severity of depression and anxiety symptoms. LIMITATIONS Although this was a cross-sectional study, the sample size was large. CONCLUSIONS Bereavement was associated with greater psychopathological burden but not with increased prevalence of MDD and anxiety disorder diagnoses, therefore highlighting the need of carefully monitoring subjects whom recently experienced bereavement. Our findings also support and provide a "cultural validator" for excluding bereavement as an exclusionary criterion for MDD diagnosis.

Abstract
BACKGROUND Schizophrenia is characterized by deficits in emotional prosody (EP) perception. However, it is not clear which stages of processing prosody are abnormal and whether the presence of semantic content contributes to the abnormality. This study aimed to examine event-related potential (ERP) correlates of EP processing in 15 chronic schizophrenia individuals and 15 healthy controls. METHOD A total of 114 sentences with neutral semantic content [sentences with semantic content (SSC) condition] were generated by a female speaker (38 with happy, 38 with angry, and 38 with neutral intonation). The same sentences were synthesized and presented in the 'pure prosody' sentences (PPS) condition where semantic content was unintelligible. RESULTS Group differences were observed for N100 and P200 amplitude: patients were characterized by more negative N100 for SSC, and more positive P200 for angry and happy SSC and happy PPS. Correlations were found between delusions and P200 amplitude for happy SSC and PPS. Higher error rates in the recognition of EP were also observed in schizophrenia: higher error rates in neutral SSC were associated with reduced N100, and higher error rates in angry SSC were associated with reduced P200. CONCLUSIONS These results indicate that abnormalities in prosody processing occur at the three stages of EP processing, and are enhanced in SSC. Correlations between P200 amplitude for happy prosody and delusions suggest a role that abnormalities in the processing of emotionally salient acoustic cues may play in schizophrenia symptomatology. Correlations between ERP and behavioral data point to a relationship between early sensory abnormalities and prosody recognition in schizophrenia.

Abstract
OBJECTIVE To assess the impact of binge eating behavior (BE) during pregnancy on birth outcomes among 697 Brazilian women who attended primary care. METHOD Pregnant women answered a questionnaire on sociodemographic data, obstetric history, and The Eating Disorder Examination Questionnaire (EDE-Q). Perinatal outcomes were obtained from birth records. Birth weight, prematurity, caesarean delivery, being small or large for gestational age were compared among women reporting BE (N = 119) and those without BE (N = 578). Poisson regression was used to estimate the association between BE during pregnancy and birth outcomes. RESULTS BE during pregnancy was not significantly associated with the birth outcomes analyzed. Gestational weight gain was significantly higher among those who reported BE. DISCUSSION Binge eating behavior during pregnancy may not influence birth outcomes as binge eating disorder does but affects gestational weight gain. Women reporting binge eating during pregnancy should undergo a diagnostic assessment for eating disorders.

Abstract
The aim of this study was to examine the prevalence of probable psychiatric disorders diagnosed during pregnancy and related sociodemographic causative factors among 712 women between the 16th and 36th week of pregnancy receiving prenatal care in 18 basic health units in Porto Alegre and Bento Gonçalves in southern Brazil. PRIME-MD was used to assess mental disorders. The prevalence of probable mental disorder occurred in 41.7% of the women. The most prevalent diagnosis was major depressive disorder (21.6%), followed by generalized anxiety disorder (19.8%). A multivariate analysis showed that the factors most significantly associated with a probable psychiatric disorder were: the fact that the pregnant woman did not work or study: PR = 1.25 (95%CI: 1.04-1.51);the fact that the pregnant woman did not live with her spouse: PR = 1.24 (95%CI: 1.01-1.52);the fact that the pregnant woman had two or more children: PR = 1.21 (95%CI: 1.01-1.46). A high prevalence of probable mental disorder was observed. The increased search for health care by pregnant women provides an opportunity for screening, diagnosing and treating these disorders under the primary health care system.

Abstract
This analysis is a follow-up to an earlier investigation of 182 genes selected as likely candidate genetic variations conferring susceptibility to anorexia nervosa (AN). As those initial case-control results revealed no statistically significant differences in single nucleotide polymorphisms, herein, we investigate alternative phenotypes associated with AN. In 1762 females, using regression analyses, we examined the following: (i) lowest illness-related attained body mass index; (ii) age at menarche; (iii) drive for thinness; (iv) body dissatisfaction; (v) trait anxiety; (vi) concern over mistakes; and (vii) the anticipatory worry and pessimism versus uninhibited optimism subscale of the harm avoidance scale. After controlling for multiple comparisons, no statistically significant results emerged. Although results must be viewed in the context of limitations of statistical power, the approach illustrates a means of potentially identifying genetic variants conferring susceptibility to AN because less complex phenotypes associated with AN are more proximal to the genotype and may be influenced by fewer genes.

Abstract
OBJECTIVE We investigated the sociodemographic characteristics in women with and without lifetime eating disorders. METHOD Participants were from a multisite international study of eating disorders (N = 2,096). Education level, relationship status, and reproductive status were examined across eating disorder subtypes and compared with a healthy control group. RESULTS Overall, women with eating disorders were less educated than controls, and duration of illness and age of onset were associated with educational attainment. Menstrual status was associated with both relationship and reproductive status, but eating disorder subtypes did not differ significantly from each other or from healthy controls on these dimensions. DISCUSSION Differences in educational attainment, relationships, and reproduction do exist in individuals with eating disorders and are differentially associated with various eating disorder symptoms and characteristics. These data could assist in educating patients and family members about long-term consequences of eating disorders.

Abstract
The analysis of jaw movements has long been used as a measure for clinical diagnosis and assessment. A number of strategies are available for monitoring the trajectory; however most of these strategies make use of expensive tools, which are often not available to many clinics in the world. In this context, this research proposes the development of a new tool capable of quantifying the movements of opening/closing, protrusion and laterotrusion of the mandible. These movements are important for the clinical evaluation of both the temporomandibular function and muscles involved in mastication. The proposed system, unlike current commercial systems, employs a low-cost video camera and a computer program, which is used for reconstructing the trajectory of a reflective marker that is fixed on the jaw. In order to illustrate the application of the devised tool a clinical trial was carried out, investigating jaw movements of 10 subjects. The results obtained in this study were compatible with those found in the literature with the advantage of using a low-cost, simple, non-invasive and flexible solution customized for the practical needs of clinics. The average error of the system was less than 1.0%.

Abstract
We performed association studies with 5,151 SNPs that were judged as likely candidate genetic variations conferring susceptibility to anorexia nervosa (AN) based on location under reported linkage peaks, previous results in the literature (182 candidate genes), brain expression, biological plausibility, and estrogen responsivity. We employed a case-control design that tested each SNP individually as well as haplotypes derived from these SNPs in 1,085 case individuals with AN diagnoses and 677 control individuals. We also performed separate association analyses using three increasingly restrictive case definitions for AN: all individuals with any subtype of AN (All AN: n = 1,085); individuals with AN with no binge eating behavior (AN with No Binge Eating: n = 687); and individuals with the restricting subtype of AN (Restricting AN: n = 421). After accounting for multiple comparisons, there were no statistically significant associations for any individual SNP or haplotype block with any definition of illness. These results underscore the importance of large samples to yield appropriate power to detect genotypic differences in individuals with AN and also motivate complementary approaches involving Genome-Wide Association (GWA) studies, Copy Number Variation (CNV) analyses, sequencing-based rare variant discovery assays, and pathway-based analysis in order to make up for deficiencies in traditional candidate gene approaches to AN.

Abstract
AIM To assess lifetime substance abuse, family history of alcohol abuse/dependence, and novelty seeking in three different eating disorder groups (anorexia nervosa-restrictive; anorexia nervosa-binge eating/purging; anorexia nervosa to bulimia nervosa). METHOD A total sample of 371 eating disorder patients participated in the current study. Assessment measures included the prevalence of substance abuse and family history of alcohol abuse/dependence as well as the novelty-seeking subscale of the Temperament and Character Inventory-Revised. RESULTS Significant differences across groups were detected for lifetime substance abuse, with anorexia nervosa-restrictive individuals exhibiting a significant lower prevalence than the anorexia nervosa to bulimia nervosa and anorexia nervosa-binge eating/ purging patients (P < 0.01). For family history of alcohol abuse/dependence the same pattern was observed (P = 0.04). Novelty seeking was associated with substance abuse (P = 0.002), with the anorexia nervosa to bulimia nervosa group exhibiting significantly higher scores on the novelty-seeking scale than the other two groups (P < 0.001). But family history of alcohol abuse/dependence was not related to novelty seeking (P = 0.092). CONCLUSION Lifetime substance abuse appears to be more prevalent in anorexia nervosa patients with bulimic features. Higher novelty-seeking scores may be associated with diagnosis cross-over.

Abstract
Anorexia nervosa is a perplexing illness with the highest mortality rate of any psychiatric disease. In this paper, we review the genetic research on anorexia nervosa (AN). Family studies have demonstrated that anorexia nervosa is familial, and twin studies have indicated that additive genetic factors contribute to the familial aggregation. Molecular genetic research, including genomewide linkage and case control association studies, have not been successful in identifying DNA variants that are unequivocally involved in the etiology of AN. We provide a critical appraisal of these studies and discuss methodological issues that may be implicated in conflicting results. Furthermore, we discuss issues relevant to genetic research such as the importance of phenotypic refinement, the use of endophenotypes, and the implications for nosology and genetic analysis. Finally, the future of genetic research for AN is discussed in terms of genomewide association studies (GWAS) and the need for establishing large samples.

Abstract
OBJECTIVE To investigate whether clusters of bulimic symptoms exist in a community sample of young Portuguese women. METHOD A total of 2028 females, aged 12-23 years, completed the Eating Disorder Examination Questionnaire (EDE-Q). Latent class analysis was applied to the seven bulimic symptoms, age, and body mass index. RESULTS The selected 4-class solution yielded a "healthy" class, reporting minimal binge eating and purging behaviors. A "binge eating" class, resembled binge eating disorder. A "purging" class had infrequent binge eating, but frequent compensatory behaviors. Finally, in a "classic bulimia nervosa" class, binge eating episodes were reported by 95% of participants, and compensatory behaviors were frequently endorsed. EDE -Q global and subscale scores differed across all latent classes. CONCLUSION In the community, three natural patterns exist: binge eating plus compensatory behaviors, binge eating only, and purging in the absence of binge eating. These results have implications for future revisions of eating disorders nosology.

Abstract
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, rs1130214, [corrected] 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.

Abstract
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.

Abstract
The present study investigated the behavioral effects of five 5-HT agonists and antagonists in the rat elevated-plus-maze using conventional and ethologically derived measures. An anxiolytic effect of the 5-HT1A agonist ipsapirone (0.25, 0.75, and 2.25 mg/kg) was detected by risk-assessment and scanning but not by percentage of open-arm entries and time spent on open arms. Anxiogenic effects of the 5-HT2C agonist TFMPP (0.1, 0.2, and 0.4 mg/kg) and 5-HT2A antagonist SR 46349B (1, 3, and 10 mg/kg) were detected by percentage of open-arm entries, time spent on open arms, scanning, end exploring, but not by risk assessment. Finally, the effects of the 5-HT3 antagonist BRL 46470 A (0.001, 0.01, and 0.1 mg/kg) and 5-HT(2A/C) antagonist RP 62203 (0.25, 1, and 4 mg/kg) were scarce in both conventional and ethologically derived measures. These results are indicative that ethological measures may sometimes be more sensitive than the standard ones, and should be used together with them when assessing serotonergic or any other novel drugs in the elevated plus-maze.
