Psicoterapia como estratégia de tratamento dos transtornos alimentares: análise crítica do conhecimento produzido

O objetivo deste estudo foi empreender uma análise crítica acerca do conhecimento científico produzido sobre a utilização das psicoterapias como estratégia de tratamento dos transtornos alimentares. A partir de buscas nas bases PsycINFO, PePSIC e SciELO, no período entre 1999 e 2011, foram recuperados 35 artigos, categorizados em: psicoterapias breves, grupais, psicodinâmicas, complementares, bem como psicoterapias aliadas a outros tratamentos, como o psicofarmacológico. As abordagens mais frequentemente mencionadas foram psicodinâmicas e cognitivo-comportamentais. A modalidade de atendimento predominante foi a grupal. Ainda que preconizando o uso combinado de diversas estratégias, a literatura é unânime em destacar a importância das psicoterapias no tratamento. A análise crítica evidenciou necessidade de leituras que transcendam a mera identificação de técnicas psicoterápicas consideradas mais eficazes para o tratamento dos transtornos alimentares. Deve-se considerar o contexto mais amplo no qual os tratamentos são propostos, bem como promover um diálogo aberto entre enfoques teóricos, valorizando a pluralidade de saberes e a psicoterapia como prática em permanente transformação.

Corpo e palavra: grupo terapêutico para pessoas com transtornos alimentares

Transtornos alimentares constituem relações problemáticas com a alimentação e a imagem de si. Seu tratamento deve contemplar múltiplas estratégias, inclusive a abordagem grupal. Este estudo teve como objetivos desenvolver reflexões sobre a grupoterapia com pessoas com transtornos alimentares atendidas em serviço especializado e investigar a dinâmica psicológica dos pacientes atendidos, a partir de ressonâncias contratransferenciais. Foram analisados registros de observação anotados em diário de campo ao longo de 21 encontros grupais consecutivos. O material foi submetido à análise de conteúdo na modalidade temática. Os resultados foram estruturados em três eixos temáticos: vivências impactantes mobilizadas no contato com os pacientes; demanda de ajuda dos pacientes para encontrarem as palavras perdidas, como via de acesso à representabilidade dos afetos elididos do espaço mental pela operação de desafetação; sentimentos contratransferenciais vivenciados pelo pesquisador. Foram discutidas as implicações para o tratamento, visando à busca de estratégias capazes de proporcionar um ambiente terapêutico que facilite a integração psicossomática.

Anorexia: a failure in the work of melancholia

The self-reproach against their own bodies seen in patients with eating disorders has led us to posit the existence of failures in the work of melancholia. Defined by Freud in 1915, this process of melancholia is aimed at repairing a loss felt as unbearable by the ego and that triggers off a violent struggle with ambivalent feelings toward the lost object. The resulting hatred is aimed at the shadow of the object that falls on the ego. Especially in anorexia nervosa, there seems to be a regressive movement that goes beyond this.

Insatisfacción corporal y actitudes alimentarias anómalas en bailarines y bailarinas

[ES] El riesgo de desarrollar trastornos de conducta alimentaria (TCA) es mayor en mujeres que en hombres de muestras comunitarias. Sin embargo, no existen datos suficientes que reflejen que esta diferencia también se mantenga en poblaciones especiales como por ejemplo, los bailarines/as. En este estudio se comparan estudiantes de población general y bailarines de ambos sexos para conocer si existen diferencias entre ellos respecto a sus actitudes alimentarias einsatisfacción con la imagen corporal.

La farmacogenetica della narcolessia: comorbidità psichiatriche e risvolti in sanità pubblica

La farmacogenetica fornisce un importante strumento utile alla prescrizione farmacologica, migliorando l’efficacia terapeutica ed evitando le reazioni avverse. Il citocromo P450 gioca un ruolo centrale nel metabolismo di molti farmaci utilizzati nella pratica clinica e il suo polimorfismo genetico spiega in gran parte le differenze interindividuali nella risposta ai farmaci. Con riferimento alla terapia della narcolessia, occorre premettere che la narcolessia con cataplessia è una ipersonnia del Sistema Nervoso Centrale caratterizzata da eccessiva sonnolenza diurna, cataplessia, paralisi del sonno, allucinazioni e sonno notturno disturbato. Il trattamento d’elezione per la narcolessia include stimolanti dopaminergici per la sonnolenza diurna e antidepressivi per la cataplessia, metabolizzati dal sistema P450. Peraltro, poiché studi recenti hanno attestato un’alta prevalenza di disturbi alimentari nei pazienti affetti da narcolessia con cataplessia, è stata ipotizzata una associazione tra il metabolismo ultrarapido del CYP2D6 e i disturbi alimentari. Lo scopo di questa ricerca è di caratterizzare il polimorfismo dei geni CYP2D6, CYP2C9, CYP2C19, CYP3A4, CYP3A5 e ABCB1 coinvolti nel metabolismo e nel trasporto dei farmaci in un campione di 108 pazienti affetti da narcolessia con cataplessia, e valutare il fenotipo metabolizzatore in un sottogruppo di pazienti che mostrano un profilo psicopatologico concordante con la presenza di disturbi alimentari. I risultati hanno mostrato che il fenotipo ultrarapido del CYP2D6 non correla in maniera statisticamente significativa con i disturbi alimentari, di conseguenza il profilo psicopatologico rilevato per questo sottogruppo di pazienti potrebbe essere parte integrante del fenotipo sintomatologico della malattia. I risultati della tipizzazione di tutti i geni analizzati mostrano un’alta frequenza di pazienti con metabolismo intermedio, elemento potenzialmente in grado di influire sulla risposta terapeutica soprattutto in caso di regime politerapico, come nel trattamento della narcolessia. In conclusione, sarebbe auspicabile l’esecuzione del test farmacogenetico in pazienti affetti da narcolessia con cataplessia.

Is dental erosion really a problem?

Dental erosion is the non-carious dental substance loss induced by direct impact of exogenous or endogenous acids. It results in a loss of dental hard tissue, which can be serious in some groups, such as those with eating disorders, in patients with gastroesophageal reflux disease, and also in persons consuming high amounts of acidic drinks and foodstuffs. For these persons, erosion can impair their well-being, due to changes in appearance and/or loss of function of the teeth, e.g., the occurrence of hypersensitivity of teeth if the dentin is exposed. If erosion reaches an advanced stage, time- and money-consuming therapies may be necessary. The therapy, in turn, poses a challenge for the dentist, particularly if the defects are diagnosed at an advanced stage. While initial and moderate defects can mostly be treated non- or minimally invasively, severe defects often require complex therapeutic strategies, which often entail extensive loss of dental hard tissue due to preparatory measures. A major goal should therefore be to diagnose dental erosion at an early stage, to avoid functional and esthetic impairments as well as pain sensations and to ensure longevity of the dentition.

Change in First-Year Women's Body Dissatisfaction in Relation to Drive for Thinness and Social Body Comparison

Drive for thinness (DT) and social body comparison (SBC) have been highly correlated with body dissatisfaction, a robust risk factor for eating disorders; however, there is little understanding of how these two variables relate to increases in body dissatisfaction over time. In the present study, I investigated how high initial levels of DT and SBC correlate with changes in body dissatisfaction and ideal body by surveying 110 first-year women at the beginning and end of their first semester. There was no significant relationship between high initial DT and SBC and changes in either body dissatisfaction or ideal body. However, high initial SBC was almost significantly correlated with change in ideal body due to women with low SBC choosing larger bodies at follow-up. In addition, women with high initial DT and SBC had higher body dissatisfaction than women with low initial levels of both variables. Women with high initial SBC chose thinner ideal bodies than women with low initial SBC. Lastly, change in body dissatisfaction was negatively correlated with change in ideal body. If replicated, I would hope these findings could contribute to a better understanding of how women’s perception of their bodies changes over the course of their first semester in college and inform interventions to address this potential risk factor for disordered eating.

Charakteristika schwer essgestörter Patientinnen in einer universitären Einrichtung und therapeutische Richtlinien

Patientinnen und Patienten mit einer schweren Essstörung (Anorexie, Bulimie, weitere) finden einerseits selten Eingang in systematische Studien, sind andererseits aber häufig auf ein stationäres Behandlungssetting in einem tertiären Zentrum angewiesen. Die kürzlich veröffentlichte S3-Leitlinie zur Behandlung von Essstörungen erlaubt eine klarere Einschätzung der Hospitalisationsbedürftigkeit schwer Essgestörter als bisher. In der vorliegenden Arbeit wurden 26 Patientinnen und Patienten mit einer schweren Essstörung, die konsekutiv auf einer spezialisierten psychosomatisch/internistischen universitären Einrichtung hospitalisiert wurden, retrospektiv hinsichtlich ihrer biologischen, psychologischen und sozialen Merkmale charakterisiert und in Bezug zur S3-Leitlinie gestellt. Die biopsychosozialen Charakteristika der untersuchten Population zeigen, dass die Hospitalisierung schwer Essgestörter im tertiärmedizinischen Setting mit einem multiprofessionellen Behandlungsteam evidenzbasiert erfolgt.

Links between body mass index, total body fat, cholesterol, high-density lipoprotein, and insulin sensitivity in patients with obesity related to depression, anger, and anxiety

OBJECTIVE: Define links between psychosocial parameters and metabolic variables in obese females before and after a low-calorie diet. METHOD: Nine female obese patients (age 36.1 +/- 7.1 years, body mass index [BMI] > 30 kg/m2) were investigated before and after a 6-week low-calorie diet accompanied by behavior therapy. Blood lipids, insulin sensitivity (Bergman protocol), fat distribution (by dual-energy X-ray absorptiometry [DEXA]), as well as psychological parameters such as depression, anger, anxiety, symptom load, and well-being, were assessed before and after the dieting period. RESULTS: The females lost 9.6 +/- 2.8 kg (p < .0001) of body weight, their BMI was reduced by 3.5 +/- 0.3 kg/m2 (p < .0001), and insulin sensitivity increased from 3.0 +/- 1.8 to 4.3 +/- 1.5 mg/kg (p = .05). Their abdominal fat content decreased from 22.3 +/- 5.5 to 18.9 +/- 4.5 kg (p < .0001). In parallel, psychological parameters such as irritability (p < .05) and cognitive control (p < .0001) increased, whereas feelings of hunger (p < .05), externality (p < .05), interpersonal sensitivity (p < .01), paranoid ideation (p < .05), psychoticism (p < .01), and global severity index (p < .01) decreased. Prospectively, differences in body fat (percent) were correlated to nervousness (p < .05). Waist-to-hip ratio (WHR) differences were significantly correlated to sociability (p < .05) and inversely to emotional instability (p < .05), whereas emotional instability was inversely correlated to differences in insulin sensitivity (p < .01). DISCUSSION: Weight reduction may lead to better somatic risk factor control. Women with more nervousness and better sociability at the beginning of a diet period may lose more weight than others.

Imipramine and diet counseling with psychological support in the treatment of obese binge eaters: a randomized, placebo-controlled double-blind study

This study with 31 obese binge eaters (body mass index [BMI] 39.5+/-8.6 kg/m(2) [SD]) was designed to assess whether diet counseling with psychological support and imipramine or placebo has an effect on the frequency of binge eating, body weight, and depression during an 8-week treatment phase. This was followed by an open medication-free phase of 6 months of continuous diet counseling with psychological support.

Reduction in total plasma ghrelin levels following catecholamine depletion: relation to bulimic and depressive symptoms

There is increasing preclinical and clinical evidence of the important role played by the gastric peptide hormone ghrelin in the pathogenesis of symptoms of depression and eating disorders. To investigate the role of ghrelin and its considered counterpart, peptide tyrosine tyrosine (PYY), in the development of bulimic and depressive symptoms induced by catecholamine depletion, we administered the tyrosine hydroxylase inhibitor alpha-methyl-paratyrosine (AMPT) in a randomized, double-blind, placebo-controlled crossover, single-site experimental trial to 29 healthy controls and 20 subjects with fully recovered bulimia nervosa (rBN). We found a decrease between peprandial and postprandial plasma ghrelin levels (p < 0.0001) and a postprandial rise in plasma PYY levels (p < 0.0001) in both conditions in the entire study population. Plasma ghrelin levels decreased in the entire study population after treatment with AMPT compared to placebo (p < 0.006). AMPT-induced changes in plasma ghrelin levels were negatively correlated with AMPT-induced depressive symptoms (p < 0.004). Plasma ghrelin and plasma PYY levels were also negatively correlated (p < 0.05). We did not observe a difference in ghrelin or PYY response to catecholamine depletion between rBN subjects and healthy controls, and there was no correlation between plasma ghrelin and PYY levels and bulimic symptoms induced by catecholamine depletion. These findings suggest a relationship between catecholamines and ghrelin with depressive symptoms.

Symptom-based subtypes of depression and their psychosocial correlates: A person-centered approach focusing on the influence of sex

BACKGROUND: Reducing the complexity of major depressive disorder by symptom-based subtypes constitutes the basis of more specific treatments. To date, few studies have empirically derived symptom subtypes separated by sex, although the impact of sex has been widely accepted in depression research. METHODS: The community-based sample included 373 males and 443 females from the Zurich Program for Sustainable Development of Mental Health Services (ZInEP) manifesting depressive symptoms in the past 12 months. Latent Class Analysis (LCA) was performed separately by sex to extract sex-related depression subtypes. The subtypes were characterized by psychosocial characteristics. RESULTS: Three similar subtypes were found in both sexes: a severe typical subtype (males: 22.8%; females: 35.7%), a severe atypical subtype (males: 17.4%; females: 22.6%), and a moderate subtype (males: 25.2%; females: 41.8%). In males, two additional subgroups were identified: a severe irritable/angry-rejection sensitive (IARS) subtype (30%) comprising the largest group, and a small psychomotor retarded subtype (4%). Males belonging to the severe typical subtype exhibited the lowest masculine gender role orientation, while females of the typical subtype showed more anxiety disorders. The severe atypical subtype was associated with eating disorders in both sexes and with alcohol/drug abuse/dependence in females. In contrast, alcohol/drug abuse/dependence was associated with the severe IARS subtype in males. LIMITATIONS:The study had a cross-sectional design, allowing for no causal inferences. CONCLUSIONS:This study contributes to a better understanding of sex-related depression subtypes, which can be well distinguished on the basis of symptom profiles. This provides the base for future research investigating the etiopathogenesis and effective treatment of the heterogeneous depression disorder.

Beyond Bullying: Transforming the Culture of Peer Abuse

Bullying needs to be understood and positioned as a form of child abuse – peer abuse. For too many people, bullying is a benign term. This article will include information collected from a wide-range of researchers and discussions with over 50,000 students that I have facilitated during the past twenty years. The content will focus on new morbidities related to bullying such as depression and suicide, obesity, eating disorders, food allergies, juvenile diabetes, truancy, and substance and alcohol abuse. Making a cultural change in our society will require identified Change Agents, along with recommendations for collaboration, policies, projects and legislation.

El 77.5% con pareja estable, el 98.1% heterosexuales y 67,3% universitarios. El 67.3% se automedicaba, el 35.1% eran tabaquistas activos; el 28.4% presentaba problemas con el alcohol y el 36.2% con la alimentación. El tabaquismo fue más frecuente entre 40-50 años (42,5%) y en E: 56.6%; MS: 21,9%; MF: 27% y O: 36.9%(p<0.05). Se incrementó la intención de abandonar el cigarrillo comparado con el año 2004 (74.6 vs 56.3%)(p<0.05). Los problemas con el alcohol fueron frecuentes entre 20 y 30 años (47.2%), en personas con pareja inestable (73.6%), sin diferencias entre los grupos y en 51.8% coexistía con tabaquismo. Los problemas de alimentación ocurrieron significativamente en MF (46,9%) comparados con MS (22.5%) (p<0.05). Se detectó automedicación en el 68.3 del Grupo O y en 48.1% del Grupo M (p<0.05). Al comparar la automedicación en las encuestas del año 2004 y 2007, se comprobó una reducción en E (87.8 vs 52.4%) y en O (77.5 vs 48.1%)(p<0.05).- Conclusiones: Se detectó elevada prevalencia de tabaquismo, problemas con el alcohol, alimentación y automedicación en todo el personal hospitalario. El tabaquismo predominó en enfermeros, los trastornos alimentarios en médicos en formación y el alcoholismo en solteros con pareja inestable.

Exploring Existentially-Based Interventions For Career Transitions in Sport

From Introduction: Career transition issues have become of increasing interest in the field of sport psychology. Confronting the end of an athletic career is an inevitable reality that every athlete will confront in his or her lifetime (Baillie, 1993), regardless of level of competition (Kerr & Dacyshyn, 2000) or the amount of free choice related to the transition. Many athletes are able to cope with the effects of the transition process effectively, and see retirement as an opportunity to pursue new ventures and identity roles in life. However, retirement from sport can be an event that often results in various adjustment difficulties for an athlete involving emotional, social, financial, and vocational conflicts. Some athletes have reported experiencing effects such as depression, eating disorders, decreased self-esteem, increased suicidality, and substance abuse (Kerr and Dacyshyn, 2000). These types of distress can be exacerbated by the fact that many athletes fail to adequately anticipate and prepare for their impending transition (Baillie, 1993), and often embark on the retirement process without any formalized support (Stier, 2007).Typically, the role of a sport psychologist has been to assist in maximizing an athlete's competitive performance during the course of their career. However, as a sport psychologist's primary responsibility is to serve active competitors and athletic organizations, this tends to come at the expense of failing to provide follow-up care for the athlete as he or she retires from sport (Taylor, Ogilvie, and Lavallee, 2006). Since the 1970's, when the efforts of professionals in European sports organizations first received attention, there has been growing interest in academic circles about career transition
