Effects of eating disorders on oral fungal diversity

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.

Semantic Equivalence of the Brazilian Portuguese version of the "Body Change Inventory"

With the increase in research on the components of Body Image, validated instruments are needed to evaluate its dimensions. The Body Change Inventory (BCI) assesses strategies used to alter body size among adolescents. The scope of this study was to describe the translation and evaluation for semantic equivalence of the BCI in the Portuguese language. The process involved the steps of (1) translation of the questionnaire to the Portuguese language; (2) back-translation to English; (3) evaluation of semantic equivalence; and (4) assessment of comprehension by professional experts and the target population. The six subscales of the instrument were translated into the Portuguese language. Language adaptations were made to render the instrument suitable for the Brazilian reality. The questions were interpreted as easily understandable by both experts and young people. The Body Change Inventory has been translated and adapted into Portuguese. Evaluation of the operational, measurement and functional equivalence are still needed.

String Quartet n degrees 02 by Villa-Lobos: a dialogue with the cyclic form of Franck, Debussy and Ravel

This article investigates Villa-Lobos's String Quartet n degrees 02, an early work by this composer, written according cyclic sonata principles, as developed by Cesar Franck and systematized by Vincent d'Indy. Another important source are the string quartets composed by Franck (1889), Debussy (1893) and Ravel (1903), which possibly served as compositional models to Villa-Lobos. In this light, the themes of the Exposition in the first movement were analyzed and this procedure reveals some harmonic and rhythmic aspects throughout all the other movements.

Nest stolen: the first observation of nest predation by an invasive exotic marmoset (Callithrix penicillata) in an agricultural mosaic

Invasive exotic species can negatively impact local biodiversity. We present here a report of a nest predation of an endemic bird species, variable oriole (Icterus pyrrhopterus) by the introduced black-tufted marmoset (Callithrix penicillata)in an agricultural landscape highly disturbed by human activities. Two nestlings were predated, by adults of the introduced marmoset during two alternate days. Antipredator behavior and vocal mimicry were observed in variable oriole, while copulation was observed in black-tufted marmoset during the predation. The use of mobbing against predators by I. pyrrhopterus was observed and it is described here by the first time. The potential impact of the introduced marmosets to local biodiversity is discussed.

ESPECTRA: Searching the Bipolar Spectrum in Eating Disorder patients

Abstract Background Bipolar Disorder (BD) is a chronic, recurrent and highly prevalent illness. Despite the need for correct diagnosis to allow proper treatment, studies have shown that reaching a diagnosis can take up to ten years due to the lack of recognition of the broader presentations of BD. Frequent comorbidities with other psychiatric disorders are a major cause of misdiagnosis and warrant thorough evaluation. Methods/Design ESPECTRA (Occurrence of Bipolar Spectrum Disorders in Eating Disorder Patients) is a single-site cross-sectional study involving a comparison group, designed to evaluate the prevalence of bipolar spectrum in an eating disorder sample. Women aged 18-45 years will be evaluated using the SCID-P and Zurich criteria for diagnosis and the HAM-D, YOUNG, SCI-MOODS, HCL-32, BIS-11, BSQ, WHOQoL and EAS instruments for rating symptoms and measuring clinical correlates. Discussion The classificatory systems in psychiatry are based on categorical models that have been criticized for simplifying the diagnosis and leading to an increase in comorbidities. Some dimensional approaches have been proposed aimed at improving the validity and reliability of psychiatric disorder assessments, especially in conditions with high rates of comorbidity such as BD and Eating Disorder (ED). The Bipolar Spectrum (BS) remains under-recognized in clinical practice and its definition is not well established in current diagnostic guidelines. Broader evaluation of psychiatric disorders combining categorical and dimensional views could contribute to a more realistic understanding of comorbidities and help toward establishing a prognosis.

Coralistas amadores: auto-imagem, dificuldades e sintomas na voz cantada

Purpose: to evaluate vocal self-perception, difficulties and presence of negative symptoms after singing of amateur choir singers of different vocal classifications, age and experience. Method: one hundred and twenty five singers answered a questionnaire containing identification data, information about self-perception of the singing voice, difficulties with singing and negative symptoms after singing. Results: the comparison considering vocal classification evidenced greater difficulties with high notes for altos and basses, greater difficulty regarding the transition to high notes for basses and greater vocal fatigue for altos. Comparing the singers by age, both adults and young adults referred more breathiness than the elderly. The adults referred better vocal intensity than the young adults. The young adults referred better timbre than adults. Regarding the experience, the less experienced singers reported self-perception of hoarseness and presence of hoarseness after singing in greater number than the experienced singers. Conclusion: the difficulties with singing are connected to the vocal classification and do not depend on age or experience. Vocal symptoms are related to the vocal classification and to the experience with singing. Negative self-perception is also related the vocal classification and to the experience with singing, and positive self-perception was more reported by experienced singers.

Influência de alterações posturais, acompanhadas por fotogrametria computadorizada, na produção da voz

INTRODUÇÃO: Há considerável evidência da importância de uma postura adequada para um bom desempenho vocal. As alterações posturais podem influenciar diretamente a projeção da voz. OBJETIVO: Identificar a influência das diferentes posturas corporais na produção da voz. MATERIAIS E MÉTODOS: Foram realizadas as análises de 25 amostras vocais de um indivíduo que emitiu a vogal sustentada /a/ em três diferentes posturas corporais: a) ortostática natural; b) anteriorização da cabeça associada com extensão da coluna cervical; c) aumento da cifose torácica associada com anteriorização de cabeça. O indivíduo foi fotografado simultaneamente ao processo de gravação da voz. Para certificar-se de que o indivíduo estava sempre na mesma posição, as posturas foram acompanhadas por fotogrametria computadorizada pelo programa Corel Draw 10®. RESULTADOS: Os resultados da fotogrametria foram analisados pelo teste de Levene que não mostrou diferenças significativas em oito dos nove ângulos estudados. A voz foi avaliada por análise acústica e avaliação subjetiva perceptivo-auditiva. A acústica foi analisada pelos testes Anova e Tukey, que mostraram diferença na variável jitter - relacionada à qualidade vocal - entre as posturas A e B. A comparação das posturas A e B e A e C pela análise perceptivo-auditiva da voz mostrou mudanças no tom, piora na qualidade e na ressonância vocal. CONSIDERAÇÕES FINAIS: As mudanças encontradas na voz provam que a melhor produção do som é na postura ereta. O fisioterapeuta é o profissional indicado para a orientação postural e correção das más posturas.

OBJETIVO: Realizar uma revisão sistemática de pesquisas relacionadas às características vocais de crianças ou adultos com deficiência auditiva usuários de implante coclear. ESTRATÉGIAS DE PESQUISA: Foi realizada uma busca com os descritores voz, qualidade da voz e implante coclear, e seus respectivos correspondentes na língua inglesa, nas bases de dados Web of Science, Bireme, portal de teses e dissertações da USP e banco de teses e dissertações da CAPES. CRITÉRIOS DE SELEÇÃO: Os critérios adotados incluíram título condizente com a proposta deste estudo, casuística necessariamente englobando crianças ou adultos com deficiência auditiva de grau severo a profundo, pré ou pós-linguais, usuários de implante coclear e que tenham passado por análise perceptivo-auditiva e/ou acústica da qualidade vocal. RESULTADOS: Vinte e sete trabalhos foram classificados seguindo-se os níveis de evidências e indicadores de qualidade empregados pela American Speech-Language-Hearing Association (ASHA). Os desenhos dos trabalhos analisados foram considerados de média e baixa evidência científica. Seis trabalhos foram classificados como nível de evidência IIb, 20 como III, e um como IV. CONCLUSÃO: A qualidade vocal da criança ou adulto com deficiência auditiva usuário de implante coclear tem sido estudada em pequena escala. Não há um número efetivo de estudos com alto índice de evidência que demonstrem com precisão os efeitos do implante coclear na qualidade vocal desses indivíduos.

Occurrence of bipolar spectrum disorder and comorbidities in women with eating disorders

Abstract Background Eating disorder (ED) patients often have comorbidities with other psychiatric disorders, especially with mood disorders. Although recent studies suggest an intimate relationship between ED and bipolar disorder (BD), the study on a broader bipolar spectrum definition has not been done in this population. We aimed to study the occurrence of bipolar spectrum (BS) and comorbidities in eating disorder patients of a tertiary service provider. Methods Sixty-nine female patients diagnosed with anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified were evaluated. The assessment comprised the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I), clinical criteria for diagnosis of the Zurich bipolar spectrum. Mann–Whitney tests compared means of continuous variables. The association between categorical variables and the groups was described using contingency tables and analyzed using the chi-square or Fisher's exact test. The level of significance alpha was set at 5%. Results The results showed that 68.1% of patients had comorbidity with bipolar spectrum, and this was associated with higher family income, proportion of married people, and comorbidity with substance use. The ED with BS group showed higher rates of substance use comorbidity (40.4%) than the ED without BS group (13.6%). Discussion These results showed that the bipolar spectrum is a common comorbidity in patients with eating disorders and is associated with correlates of clinical importance, notably the comorbidity with substance use. Due to the pattern of similarity between the groups with and without comorbid bipolar spectrum in relation to various outcomes evaluated, the identification of comorbidity can be difficult. However, the precise diagnosis and careful identification of clinical correlates may contribute to future advances in treating these conditions. Further studies are necessary to evaluate the association of other clinical correlates and its possible causal association.
