    (2016) BRITO, Maria Jose Azevedo de; NAHAS, Fabio Xerfan; CORDAS, Taki Athanassios; GAMA, Maria Gabriela; SUCUPIRA, Eduardo Rodrigues; RAMOS, Tatiana Dalpasquale; FELIX, Gabriel de Almeida Arruda; FERREIRA, Lydia Masako
    Body dysmorphic disorder (BDD) is one of the most common psychiatric conditions found in patients seeking cosmetic surgery, and body contouring surgery is most frequently sought by patients with BDD. To estimate the prevalence and severity of BDD symptoms in patients seeking abdominoplasty. Ninety patients of both sexes were preoperatively divided into two groups: patients with BDD symptoms (n = 51) and those without BDD symptoms (n = 39) based both on the Body Dysmorphic Disorder Examination (BDDE) and clinical assessment. Patients in the BDD group were classified as having mild to moderate or severe symptoms, according to the BDDE. Body weight and shape concerns were assessed using the Body Shape Questionnaire (BSQ). The prevalence of BDD symptoms was 57%. There were significant associations between BDD symptoms and degree of body dissatisfaction, level of preoccupation with physical appearance, and avoidance behaviors. Mild to moderate and severe symptoms of BDD were present in 41% and 59% of patients, respectively, in the BDD group. It was found that the more severe the symptoms of BDD, the higher the level of concern with body weight and shape (P < .001). Patients having distorted self-perception of body shape, or distorted comparative perception of body image were respectively 3.67 or 5.93 times more likely to show more severe symptoms of BDD than those with a more accurate perception. Candidates for abdominoplasty had a high prevalence of BDD symptoms, and body weight and shape concerns were associated with increased symptom severity.

    An Examination of the Relationships between Eating-Disorder Symptoms, Difficulties with Emotion Regulation, and Mental Health in People with Binge Eating Disorder
    (2023) LUZ, Felipe Q. da; MOHSIN, Mohammed; JANA, Tatiana A.; MARINHO, Leticia S.; SANTOS, Edilaine dos; LOBO, Isabella; PASCOARELI, Luisa; GAETA, Tamiris; FERRARI, Silvia; TEIXEIRA, Paula C.; CORDAS, Taki; HAY, Phillipa
    Eating disorders, such as binge eating disorder, are commonly associated with difficulties with emotion regulation and mental-health complications. However, the relationship between eating-disorder symptoms, difficulties with emotion regulation, and mental health in people with binge eating disorder is unclear. Thus, we investigated associations between eating-disorder symptoms, difficulties with emotion regulation, and mental health in 119 adults with binge eating disorder. Participants were assessed with the Eating Disorder Examination Questionnaire, Loss of Control over Eating Scale, Difficulties in Emotion Regulation Scale, Depression Anxiety and Stress Scale, and the 12-Item Short Form Survey at the pre-treatment phase of a randomized controlled trial. Structural-equation-modelling path analysis was used to investigate relationships between variables. We found that (1) eating-disorder behaviors had a direct association with depression, anxiety, and stress; (2) depression, psychological stress, difficulties with emotion regulation, and eating-disorder psychopathology had a direct association with mental-health-related quality of life; and (3) eating-disorder psychopathology/behaviors and stress had a direct association with difficulties with emotion regulation. Our findings show that depression, stress, difficulties with emotion regulation, and eating-disorder psychopathology were related in important ways to mental-health complications in people with binge eating disorder.

    Compreendendo a psicopatologia do transtorno dismórfico corporal de pacientes de cirurgia plástica: resumo da literatura
    ABSTRACT Introduction: Individuals with Body Dysmorphic Disorder (BDD) may seek cosmetic surgery to correct a perceived defect. BDD prevalences ranging from 6% to 24% and up to 53% have been reported among cosmetic surgery patients. Recent studies have been conducted to identify the pathophysiology of BDD symptoms using neuroimaging, as well as the relationship of BDD to other disorders (e.g., obsessive-compulsive disorder, anorexia nervosa, social anxiety, and somatization disorder), and means to distinguish delusional from non-delusional beliefs as an expression of a single mental disorder at different severity levels. Retrospective studies have however suggested that BDD patients do not benefit from cosmetic surgery. This paper aimed at providing an overview of the current research on BDD and identifying psychopathological characteristics of BDD in cosmetic surgery patients. Methods: The PubMed and Embase databases were searched by crossing the keywords “plastic surgery”, “aesthetic surgery” and “body dysmorphic disorder”. Results: The prevalence of BDD was high among cosmetic surgery patients. No prospective studies were found on the impact of cosmetic surgery on BDD patients. Conclusion: BDD needs to be adequately assessed during patient selection for cosmetic surgery to optimize the quality of care provided and the quality of life of patients with BDD.

    Psychometric evaluation of the ""Body Checking and Avoidance Questionnaire - BCAQ"" adapted to Brazilian Portuguese
    (2011) KACHANI, A. Trejger; HOCHGRAF, P. Brunfentrinker; BRASILIANO, S.; BARBOSA, A. L. Rodrigues; CORDAS, T. A.; CONTI, M. A.
    OBJECTIVE: Adapt and validate the Brazilian Portuguese version of the Body Checking and Avoidance Questionnaire (BCAQ). METHODS: The study consisted of: translation and back translation; technical review and assessment of semantic equivalences, factor analysis and discriminant and concurrent validity in a sample of subjects with and without eating disorders. RESULTS: The instrument was adapted and was found to be easy to understand (mean scores higher than 3.4; maximum score: 5.0) and showed excellent concordance (Cronbach's alpha: 0.94). Factor analysis identified five components with eigenvalues greater than 1. It was able to discriminate the two groups (p<0.001) and correlated with the Eating Attitudes Test (EAT) (r=0.50), body shape questionnaire (BSQ) (r=0.68) and Beck Depression Inventory (BDI) scales (0.51). DISCUSSION: The Brazilian Language version showed suitable internal consistency and external validation, and was easy to understand. The results were similar to the original version and its use is recommended for evaluation of body checking in the Brazilian population in subjects with or without eating disorders.

    Body checking and associated cognitions among Brazilian outpatients with eating disorders and nonpsychiatric controls
    (2013) KACHANI, Adriana T.; BRASILIANO, Silvia; CORDAS, Taki A.; HOCHGRAF, Patricia B.
    This work aims to compare in patients with anorexia nervosa, bulimia nervosa, and control subjects: (a) body checking types, frequency, and parts; (b) prevalence of body avoidance and the most checked body parts; (c) body checking cognitions. Eighty-five outpatients with eating disorders (ED) and 40 controls filled out validated body checking and cognition questionnaires. ED patients, especially bulimia nervosa, check their bodies more than do the control subjects. The most checked area was the belly. The most frequent means of body checking was mirror checking, while the most avoided was weighing. The reasons that participants in the various study groups check their bodies seem to differ. Given the importance of body checking in the etiology and maintenance of EDs, it is important that clinicians consider this behavior, as well as the factors that lead to checking/avoidance in the different eating disorder subtypes, so that treatment may be more specific.

    Effects of eating disorders on oral fungal diversity
    (2012) BACK-BRITO, Graziella Nuernberg; MOTA, Adolfo Jose da; BERNARDES, Luciano Angelo de Souza; TAKAMUNE, Silvia Satomi; PRADO, Eliane de Fatima Gomes Barbosa; CORDAS, Taki Athanassios; BALDUCCI, Ivan; NOBREGA, Francisco Gorgonio da; KOGA-ITO, Cristiane Yumi
    Background. The eating disorders anorexia and bulimia nervosa can cause several systemic and oral alterations related to poor nutrition and induced vomiting; however, the oral microflora of these patients is poorly studied. Objective. The aim of this study was to evaluate fungal microflora in the oral cavity of these patients by culture-dependent and culture-independent methods. Study Design. Oral rinse samples were cultured to assess the prevalence of Candida species, and the isolates were identified by API system. Microorganism counts were compared by the Mann-Whitney test (5%). Ribotyping, a type of molecular analysis, was performed by sequencing the D1/D2 regions of 28S rRNA. Results. Our results demonstrated that the eating disorder group showed higher oral Candida spp. prevalence with culture-dependent methods and higher species diversity with culture-independent methods. Conclusions. Eating disorders can lead to an increased oral Candida carriage. Culture-independent identification found greater fungal diversity than culture-dependent methods.

    Validation of scales for pathological love assessment
    (2011) BERTI, Marina Perito; ZILBERMAN, Monica Levit; SOPHIA, Eglacy Cristina; GORENSTEIN, Clarice; PEREIRA, Ana Paula; LORENA, Andrea; MELLO, Cidalia; CORDAS, Taki Athanassios; TAVARES, Hermano
    Background: Several methodologies were developed to validate psychometric instruments. However, there are, in the scientific literature, a lack of instruments to evaluate romantic relationship. Objective: The present work aims at validating into Portuguese the content of the self-report Love Attitudes Scale (Escala de Atitudes do Amor - Hendrick et al., 1998), the Relationship Assessment Scale (Escala de Avaliacao do Relacionamento - Hendrick, 1988), and the Adult Attachment Types (Tipos de Apego do Adulto - Hazan et al., 1987), taking the Brazilian cultural context into consideration, thus rendering the study of pathological love in the Brazilian population feasible. Methods: Such process involved four stages: (1) translation into Portuguese, (2) back translation, (3) presentation of the translated version to mental health professionals and university students, and (4) application of the final version in a sample of the target population using a rating scale. Results: The scales were easily understood and significantly discriminated individuals with pathological love and healthy volunteers. Discussion: Our results show that the Brazilian version of these instruments is valid and may be used in investigations involving romantic relationships.

    A systematic review with meta-analyses of the relationship between recurrent binge eating and sleep parameters
    (2023) LUZ, Felipe Q. da; SAINSBURY, Amanda; SALIS, Zubeyir; HAY, Phillipa; CORDAS, Taki; MORIN, Charles M.; PAULOS-GUARNIERI, Leo; PASCOARELI, Luisa; RAFIHI-FERREIRA, Renatha El
    BackgroundSleep problems are known to compound the negative effects of other health issues, such as eating disorders and the associated behavior of binge eating. Previous studies suggested associations between binge eating and sleep problems, but the strength of the relationship is unknown. MethodsWe conducted a systematic review with meta-analyses examining the relationship between binge eating and sleep parameters. We searched for studies in Scopus, PubMed, and PsycInfo. The quality of evidence, including risk of bias, was assessed with adaptations of the Newcastle-Ottawa Scale and the Joanna Briggs Institute Critical Appraisal Checklist for Quasi-Experimental Studies, depending on study design. Data was synthesized as the difference in sleep between people who did or did not have binge eating. ResultsThirty-one reports of studies met our eligibility criteria. Results are presented in 12 meta-analyses. In the 7 reports of studies (with 4448 participants) that assessed poor overall sleep quality, we found poorer overall sleep quality in people with binge eating compared to people without binge eating, with a standardized mean difference of 0.77 (95% confidence interval [CI] 0.61-0.92; P < 0.001), which is a large effect size. In addition, we found evidence that people with binge eating had significantly greater hypersomnia/daytime sleepiness (7 reports of studies with 4370 participants), insomnia (5 reports of studies with 12,733 participants), and difficulty falling asleep (3 reports of studies with 4089 participants) compared to people without binge eating, with moderate effect sizes (standardized mean differences of 0.57-0.66). ConclusionsPeople with binge eating exhibit poorer overall sleep quality compared to people without binge eating, and may also exhibit greater hypersomnia/daytime sleepiness, insomnia, and difficulty falling asleep. It is recommended that healthcare professionals routinely screen for poor overall sleep quality when treating people with binge eating-and address sleep difficulties when present.
