La anorexia nerviosa es el trastorno de la conducta alimentaria con las mayores tasas de mortalidad entre los trastornos psicológicos, además debido a la complejidad de su curso clínico los profesionales se encuentran con dificultades a la hora de realizar una intervención. En la primera parte, se realizó una revisión conceptual de la anorexia y bulimia nerviosa y, de otros trastornos que coexisten con ellos. En la segunda parte se analiza un caso real de anorexia nerviosa, mediante el anális...

Los trastornos de la conducta alimentaria se han convertido en un importante tema relacionado a la salud debido a sus altos índices de prevalencia y mortandad así como las enfermedades que éstos conllevan. El objetivo principal de esta investigación fue analizar si las personas que presentan sintomatología del trastorno de Anorexia Nerviosa utilizan las dietas restrictivas y la perdida de peso corporal como una manera de reducir la tensión y por lo tanto, como un modo de af...

Full Text Available La anorexia nerviosa es una enfermedad psiquiátrica, cuya incidencia está creciendo en las últimas décadas. Afecta sobre todo a las adolescentes y mujeres jóvenes. Los signos clínicos son consecuencia de las carencias nutricionales y de los mecanismos de compensación, que el organismo implementa para conservar la vida. Las manifestaciones cutáneas y bucales son consecuencia de la desnutrición: vómitos autoprovocados, consumo de drogas o medicamentos no recetados y de la enfermedad psiquiátrica en sí misma. Se presentan diez pacientes, ocho mujeres y dos varones con signos cutáneos compatibles con anorexia nerviosa. El rango de edad es de 17 a 32 años. En orden de frecuencia se hallaron: acrocianosis, alopecia, acné, xerosis, palidez, hirsutismo, cambios en las membranas bucales y lesiones autoprovocadas. Creemos que el reconocimiento de estos signos cutáneos acompañado de un exhaustivo interrogatorio, puede colaborar en el diagnóstico de este trastorno alimentario.Anorexia nervosa is a psychiatric disease with an increasing incidence in the last decade, which affects principally adolescents and young women. Clinical signs are a consequence of malnutrition and the compensating mechanisms implemented to preserve life. Skin and oral lesions are caused by malnutrition, self-provoked vomiting, illegal drug consumption or therapeutic drugs utilization, and the psychiatric disease so far. Case reports: ten patients (eight females and two males with possible skin alterations due to anorexia nervosa, aged 17 to 32 yr. The most frequent signs, in order of priority were: acrocyanosis, alopecia, acne, xerodermia, pallor, hirsutism, oral injuries and self provoked injuries. We propose that the finding of these skin lesions plus an exhaustive questionnaire could aid to diagnose this eating disorder.

Los cambios neuroquímicos presentes en la anorexia nerviosa también se han atribuido a la desnutrición, y es probable que puedan perpetuar las alteraciones conductuales.A clinical review of the syndrome of anorexia nervosa is made, giving emphasis to its concept, development and clinical picture. It is a disorder that appears commonly in adolescents without an exaggerated obesity and with just a discrete overweight. Studies have been conducted that show a significant relation between the symptoms and the interpersonal functioning of the anorexic adolescents, since they tend to be isolated or to be accompanied by younger persons. The obesive compulsive disorders associated or not with food are also characterisitcs of this picture. The restricted diet leads to important biological and physical changes, among which the alteration of the hypothalamic and endocrine system, which gives rise to the appareance of signs and symptoms such as amenorrhea, intolerance to cold and hypotension, is stressed.

Full Text Available De acuerdo con la observación clínica, y en algunos casos con la literatura experimental, los trastornos alimenticios van asociados a insatisfacción con la imagen corporal, así como a baja autoestima o un mal autoconcepto, y aislamiento social, alexitimia, etc. que conllevarían dificultades en las relaciones sociales. Pero ¿son estos aspectos característicos de las personas que padecen anorexia y bulimia nerviosa los que permiten diferenciarlos claramente de otros grupos?. El objetivo del presente estudio es pues, comparar pacientes con Anorexia y Bulimia Nerviosa con tres grupos: control, mujeres que hacen dieta y mujeres en psicoterapia, en medidas de autoconcepto-autoestima, satisfacción con el propio cuerpo y habilidades sociales. Los resultados apoyan la idea de que un mal autoconcepto y ciertos déficits en habilidades sociales son característicos de pacientes con anorexia y bulimia nerviosa, y que los diferencian no sólo de grupos controles normales, sino también de personas que hacen dieta para adelgazar. La insatisfacción con el propio cuerpo caracteriza al grupo de anorexia, diferenciandole tanto del grupo control, como del de psicoterapia y del de dieta.

Anorexia nervosa is a multidimensional disorder, the causes of which are also numerous. Sociocultural factors play a key role in its etiology, though it is the biological factors that lead to the medical pathology and act as signzficant primary and secondary causal agents. A review of the literature reveals the existence of predisposing (genetic, of maturation) and maintaining (biochemical, gastric, metabolic and growth) biological factors, all of which are related to malnutrition.

Los trastornos más conocidos de la alimentación como la anorexia nerviosa y la bulimia son entidades de orden psíquico que no poseen un factor etiológico único; se destaca la constante carga publicitaria que ha transformado el concepto de imagen corporal y los patrones alimentarios.
Se ha observado que representan un problema de salud; los
grupos más vulnerables son las mujeres de 13-18 años (0.5-1% en anorexia, y 1-5% en bulimia. Ambas entidades generalmente son de curso crónico y traen consecuencias tanto físicas como sicológicas, que incluso pueden acarrear la muerte de quienes la padecen. Conociendo su potencial peligrosidad y el incremento de las imágenes visuales y las presiones socioculturales que inducen diariamente a estar delgado, a cambiar los hábitos alimentarios y a realizar ejercicio, consideramos que es de suma importancia realizar un estudio de uno de los principales síndromes psiquiátricos modernos, siguiendo de cerca los factores predisponentes y la prevalencia en el grupo de personas que están en mayor riesgo de presentarlos como son las mujeres adolescentes y en la adultez temprana.

Full Text Available Partiendo de la teoría de Merton sobre la desviación, por la cual ciertos tipos de anomalías en la conducta derivan de la disociación entre las aspiraciones prescritas culturalmente y el acceso a los medios correctos para lograrlas, se llega a la conclusión de que la anorexia nerviosa y la bulimia son una típica respuesta a una situación de anomia. La belleza del cuerpo como objetivo cultural presenta una fuerte naturaleza anómica porque es esencialmente un atributo físico innato que no le ofrece al sujeto ningún modo de lograrlo si no se tiene. La belleza adquirida, que expresa la posibilildad que el individuo tiene de mejorar ciertos aspectos, juega un papel muy reducido. Acceder a los medios de adquirirla es algo restringido, como lo es todo lo contenido en un objeto de consumo y en el sistema de servicios, tanto económica como culturalmente.

Impulsividad y búsqueda de sensaciones: factores asociados a síntomas de anorexia y bulimia nerviosas en estudiantes de secundaria (Impulsiveness and sensation seeking: Factors associated with symptoms of anorexia and bulimia nervosa in high school students
Full Text Available This study investigated the potential association of impulsiveness and sensation seeking and the attitudes and behaviour characteristic of anorexia and bulimia nervosa in male and female students (between 12 and 20 years. The study had an observational case-control design, in which the case group comprised symptomatic subjects who had scores above the cutoff point designated by the authors for several assessment instruments, and the control group, which comprised asymptomatic participants who had scores below the cutoff point. The study included 300 participants (136 men [45.33%] and 164 women [(54.66%] from Malaga (Spain. All participants received parental authorization to take part in the study. The participants anonymously completed the following self-administered tests: Eating Disorder Inventory (EDI-II, Eating Attitudes Test (EAT-26, Bulimia Test Revised (BULIT-R, Barratt Impulsiveness Scale (BIS-11, and (SSS-V. The results suggest an association between impulsiveness and symptomatology associated with eating disorders, anorexia, and bulimia nervosa. In contrast, sensation seeking was only associated with bulimic symptoms. In summary, the variables impulsivity and sensation seeking appear to be closely associated with eating disorders. Thus, these aspects should be addressed in healthy lifestyle programs, because their inclusion may help to reduce or prevent the increase in eating disorders in the teenage population.

Anorexia nervosa and bulimia nervosa are at the present moment, two well defined clinical entities among the group of the eating disorders. The psychopathological differentiation of both syndromes has a great importance for diagnosis and therapy. The authors make a phenomenological description, based on case histories of patients with diagnostics of anorexia and bulimia nervosa, and try to establish an approach to the essential symptomatology of those disorders. The presence of affective symptomatology--depressive, but not exclusively--in the eating behaviour disorders in general and particularly in bulimia nervosa, is nowadays interpreted as an unspecific emotional lability as a response to stressing situations. That is to say, it is a secondary depressive symptomatology, more than a primary mood disorder preceding or underlying bulimia. There is strong evidence in favour of a dysregulation of serotonin metabolism in patients with bulimia nervosa, in the sense of a reduced activity, which manifest itself clinically by binges with food with a high content in carbohydrates. High levels of 5-HT seem to induce increasing feelings of safety, fullness and lead to an interruption of eating. Fluoxetine and this active metabolite are selective inhibitors of the reuptake of 5-HT and their antibulimic effect could be mediated by this mechanism.

Full Text Available La Anorexia Nervosa es un trastorno de alimentación que se define (etimológicamente como una "pérdida nerviosa del apetito". Se caracteriza por la actitud consciente, voluntaria y rotunda de los sujetos de tener un exceso de peso que intentan modificar por vía de la inanición. A partir del estudio de casos, se propone la distinción entre una Anorexia Nervosa Estructural -aquella en la que predomina el conflicto intrapsíquico primario y arcaico, y que manifiesta una conducta aislada y retraída- y una Anorexia Nervosa Reactiva, aquella en la que predomina un conflicto intrafamiliar algo más posterior y, por lo tanto, una personalidad más abierta y compatible con el medio. Anorexia Nervosa is an Eating Disorder defined (etimoligacally as a "nervouse loss of apetite". It is characterized by a conscious, voluntary and categoric attitude of the sick patient to refrain from eating. He/she has a firm conviction of having excess weight which they try to modify by starvation. Through a case study, a distinction between two types of Anorexia Nervosa is proposed: a Structural Anorexia Nervosa -in which an intrapsyhic, primary, arcaic conflic prevails, leading to an isolated, withdrawal conduct- and a Reactive Anorexia Nervosa, in which a later intrafamilial conflict prevails leading, therefore, to a more open personality, compatible with the enviroment.

Participaron 64 personas significativas de los individuos con anorexia nerviosa, a los que se les pidió que indicasen el grado de identificación, de acuerdo con su familiar, con cinco narrativas prototipo distintas (depresión, agorafobia, anorexia, alcoholismo y tóxico-dependencia. Los resultados no confirmaron la validez divergente de la narrativa prototipo de la anorexia. Los participantes mostraron tendencia a identificar en primer lugar a sus familiares con el prototipo de la agorafobia. Además, no se encontraron diferencias significativas entre la identificación con el prototipo de la anorexia y el de la depresión, de la agorafobia y del alcoholismo. La única diferencia significativa encontrada fue en la comparación entre el prototipo de la anorexia y el de la tóxico-dependencia. No obstante, las madres de las anoréxicas y la duración del trastorno se asocian al grado de identificación con la narrativa prototipo de la anorexia. Se discuten los resultados en términos de una aproximación sistémica versus prototipo de las perturbaciones del comportamiento alimentario.

Full Text Available Resumen INTRODUCCIÓN Se ha planteado que la estimulación del apetito con cannabinoides podría constituir una alternativa terapéutica en anorexia nerviosa. Sin embargo, su utilidad clínica y seguridad genera controversia. MÉTODOS Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, preparamos tablas de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos cuatro revisiones sistemáticas que en conjunto incluyen dos estudios primarios, ambos correspondientes a ensayos aleatorizados. Concluimos que los cannabinoides podrían no aumentar el peso ni mejorar la sintomatología en la anorexia nerviosa, y se asocian a efectos adversos frecuentes.

Full Text Available Este estudio es la continuación de otro en el que se elaboró una narrativa prototipo de la anorexia y se analizó su validez convergente (grado de verosimilitud. Se plantean tres objetivos: analizar la validez divergente (grado de discriminación de la narrativa prototipo de la anorexia, explorar aspectos de la historia de los sujetos que puedan estar asociados a una diferencia de intensidad en la identificación con la narrativa de la anorexia y, por último, realizar un estudio exploratorio del poder predictivo de algunas de las variables descriptivas de la muestra en relación a la identificación con la narrativa prototipo de la anorexia. La muestra está formada por 38 sujetos con diagnóstico de anorexia nerviosa según los criterios del DSM-IV. Los resultados no confirman la validación divergente de la narrativa prototipo de la anorexia, poniendo en duda la hipótesis de su veracidad. No obstante, en los tres subgrupos de la muestra relacionados a la duración del trastorno superior a 2,5 años, la puntuación total del EDI y la subescala de Miedo a la Madurez encima del punto de corte, los sujetos se identifican más con la narrativa prototipo de la anorexia que con la de la toxicodependencia y la de la agorafobia. La duración de la perturbación de más de 2,5 años se revela como variable predictiva de la identificación con la narrativa prototipo de la anorexia.

Full Text Available Relato biográfico de Sonia, una enfermera que sufrió anorexia y bulimia nerviosa, cuando estaba cursando la carrera de enfermería. El objetivo ha sido conocer de las palabras de la propia informante, cómo se vive la anorexia desde la perspectiva de una enfermera con conocimientos amplios sobre el tema, y cómo desde su posición de profesional puede ayudar a otros. Para construir el relato he realizado una entrevista semiestructurada, con preguntas abiertas centradas en los temas esenciales. La informante relata su historia describiendo aspectos como la percepción de lucha interna con la que describe el factor desencadenante y el desarrollo de la enfermedad, las estrategias de afrontamiento que utiliza para recuperar la salud y la principal motivación que la llevó a tomar conciencia del problema y querer tomar el control de su vida. Este tipo de relatos puede servir de ayuda y aprendizaje a la sociedad y en especial a otros jóvenes que pueden verse reflejados en el mismo.

Full Text Available Anorexia nervosa is a disease involving eating disorders. It mainly affects young people, especially teenage women. The disease is often latent and occurs in many sub-clinical and partial forms. Approximately from 0.3% to 1% of the population suffers from anorexia. It has been shown that patients with anorexia develop neurotransmitter-related disorders, leading to uncontrolled changes in the immune and endocrine systems. Interactions between cytokines, neuropeptides, and neurotransmitters play an important role in disease development. Significant malnutrition induces disorders and alterations in T-cell populations. The cellular response in patients with anorexia nervosa has been shown to be normal, although opinions on this issue are controversial. Laboratory studies on neutrophils in anorexia patients showed decreased adhesion and reduced bactericidal and cell activities. Despite such unfavourable results, patients with anorexia are resistant to infections, which are very rare in this group. Glutamine improves the performance of the human immune system. The administration of glutamine to anorexia patients, as a supplement to parenteral nutrition, has resulted in significant improvements in immune system parameters. The results of previous studies on the causes and risk factors in the development of anorexia nervosa are still ambiguous. One can hope that the differences and similarities between patients with anorexia nervosa and those with other forms of protein-calorie malnutrition may be helpful in determining the relationship between nutritional status and body defences and susceptibility to infection, and can help to broaden the knowledge about the aetiopathogenesis of anorexia nervosa.
Full Text Available En condiciones normales sólo ocurre mielinización de fibras del nervio óptico por detrás de la lámina cribosa, pero se observa mielinización de parte de la capa de fibras nerviosas de la retina en el 0.32% a 0.98% de los pacientes. la mielinización intraocular generalmente es yuxtapapilar, y las fibras toman un aspecto característico: manchas blancas, nacaradas, parecidas a una pluma, que siguen la dirección de las fibras de la retina y a veces ocultan la papila. Aparte de estas características fundoscópicas, la mayoría de los pacientes son normales. Se ha encontrado que puede haber una asociación entre la mielinización de las fibras de la retina y una miopía ipsilateral, y también se ha observado ambliopía y estrabismo. Se describe un caso de mielinización de fibras nerviosas, en madre e hija, hecho que sugiere un factor genético en su génesis.
Full Text Available Los tumores malignos de la vaina nerviosa periférica (TMVNP, también llamados neurofribrosarcomas o schwannomas malignos, representan el 10% de todos los sarcomas de tejidos blandos. El tumor usualmente se encuentra en las extremidades inferiores, y solo del 10 al 20% de las lesiones ocurren en la región de cabeza y cuello, convirtiéndolas en una entidad rara. Los neurofibromas son tumores de la vaina nerviosa que aparecen comúnmente en la neurofibromatosis 1 o enfermedad de Von Recklinghausen. Se ha reportado que los individuos con antecedentes familiares de neurofibromatosis 1 tienen un riesgo incrementado de desarrollar TMVNP en el transcurso de sus vidas, sin embargo, esta asociación no se ha confirmado en TMVNP a nivel de los nervios craneales. En este artículo los autores analizaron la literatura actual con respecto a los TMVNP del nervio trigémino, así como la inclusión de un caso inusual que involucra las 3 ramas de dicho nervio.

Las ayudas diagnósticas que permitan la evaluación de su extensión y severidad resultan de importancia puesto que así se tendrán herramientas confiables para cuantificar la gravedad del problema. Objetivo: determinar la concordancia interexaminador para la detección de hallazgos radiográficos en pacientes con periodontitis crónica localizada empleando radiografía periapical convencional. Métodos: estudio de pruebas diagnósticas incluyendo pacientes con periodontitis crónica localizada, sobre el diente con peor nivel de inserción clínico y a través de una sola radiografía convencional por órgano dentario empleando técnica de paralelismo. Las valoraciones radiográficas fueron realizadas por dos evaluadores independientes y cegados para los hallazgos: lámina dura, defectos óseos y tipo de defecto. El acuerdo obtenido se estimó a través de Kappa de Cohen. Resultados: se tomaron en total 125 radiografías. La edad promedio fue 38,8±9,9 años, y 61,6% eran mujeres. La concordancia para lámina dura fue 0,08 (IC 95 %: -0,04 - 0,21, defectos óseos 1,00 (IC 95 %: 1,00 - 1,00; tipo de defecto presente 0,31 (IC 95 %: 0,29 - 0,38. Conclusiones: la concordancia se evaluó como nula, casi perfecta y aceptable para los hallazgos lámina dura, presencia de defectos óseos y tipo de defecto respectivamente. Para algunos hallazgos y dada la importancia de los procesos diagnósticos y terapéuticos se necesitan valoraciones más exactas que se traduzcan en un mayor grado de acuerdo.
The anorexia of aging is common, leading to adverse health consequences. As populations age, the impacts from anorexia in the older population are set to increase. Only greater awareness will allow for prevention or early intervention. This article discusses the physiologic anorexia of aging, highlights contributing factors, and proposes management strategies, including screening, especially in primary care. Many neuroendocrine factors have been implicated in the pathophysiology; it is clear that further human research is necessary if there is to be a pharmacologic breakthrough. There are currently no approved pharmacologic treatment strategies to prevent or treat the anorexia of aging. Copyright © 2015 Elsevier Inc. All rights reserved.

Full Text Available En este artículo nos proponemos recuperar el trabajo de Merlau-Ponty como un instrumento válido para la elaboración de una psicología crítica ya sea en como referente teórico o en sus aplicaciones prácticas. En concreto, nos vamos a centrar en los conceptos de percepción y corporalidad y como Merleau-Ponty los define de forma radicalmente distinta a la psicología convencional. Complementariamente, reflejamos el carácter crítico de las perspectivas fenomenológicas mediante la aplicación de los conceptos de percepción y corporalidad a la concepción clínico-teórica de la anorexia nerviosa. Este artículo constituye un punto de partida que nos permita repensar la naturaleza encarnada de la anorexia nerviosa, tanto a partir de una crítica fenomenológica al concepto de corporalidad en la concepción de los desórdenes alimentarios de la psicología clínico-conductual como la ausencia de la noción de cuerpo encarnado en algunas perspectivas feministas.

Full Text Available This study’s objective was to understand how occupational roles of individuals with anorexia nervosa are configured. The sample was composed of a control group and 11 adult women with anorexia nervosa being cared for by the Eating Disorders Care Group in a hospital in Ribeirão Preto, SP, Brazil. Socio-demographic and anthropometric data were collected and the Role Checklist was applied. The results revealed a significant loss of roles for women with anorexia nervosa in relation to the performance of the roles worker, friend, and amateur/hobbyist, supporting the idea that psychosocial harm may arise from this eating disorder. The evaluation of occupational roles in the treatment of eating disorders is an important strategy for planning Occupational Therapy activities and supporting the creation of healthier spaces to enable individuals to resume occupational roles, and acquire independence and autonomy.El objetivo es entender como figuran los papeles ocupacionales de las personas con anorexia nervosa.

Introduction Anorexia nervosa is an eating disorder, which is associated with many different medical complications as a result of the weight loss and malnutrition that characterise this illness. It has the highest mortality rate of any psychiatric disorder. A large portion of deaths are attributable to the cardiac abnormalities that ensue as a result of the malnutrition associated with anorexia nervosa. In this review, the cardiac complications of anorexia nervosa will be discussed. A comprehensive literature review on cardiac changes in anorexia nervosa was carried out. There are structural, functional, and rhythm-type changes that occur in patients with anorexia nervosa. These become progressively significant as ongoing weight loss occurs. Cardiac changes are inherent to anorexia nervosa and they become more life-threatening and serious as the anorexia nervosa becomes increasingly severe. Weight restoration and attention to these cardiac changes are crucial for a successful treatment outcome.

Anthropological concepts of relatedness have not been addressed in any of the writings on anorexia, despite the literature being replete with negative connotations of sociality such as withdrawal, regression, and toxic families (in the form of 'obsessive mothers' or 'absent fathers'). As a departure to the vast literature on this topic, this multi-sited ethnographic project draws on the recent critiques and broadening of the concept of kinship to examine the ways in which a group of people with a diagnosis of anorexia understood and experienced relatedness in their everyday lives, that is, how they continually transformed connections by truncating, creating, sustaining and abandoning them. Those practices that are taken for granted as creating and sustaining relatedness-from the everyday practices of commensality to the capacity to have children-were consistently negated. Negating consensual avenues of relatedness did not leave these people in a void. On the contrary, new and productive meanings and experiences of being related were created and people entered into a relationship with anorexia that, in turn, tempered their relationships with their everyday worlds. In examining the 'relational matrix' of anorexia, new spaces of agency, ambiguity and power are illuminated.

We have suggested that reduced food intake increases the risk for anorexia nervosa by engaging mesolimbic dopamine neurons, thereby initially rewarding dieting. Recent fMRI studies have confirmed that dopamine neurons are activated in anorexia nervosa, but it is not clear whether this response is due to the disorder or to its resulting nutritional deficit. When the body senses the shortage of nutrients, it rapidly shifts behavior toward foraging for food as a normal physiological response and the mesolimbic dopamine neurons may be involved in that process. On the other hand, the altered dopamine status of anorexics has been suggested to result from a brain abnormality that underlies their complex emotional disorder. We suggest that the outcomes of the treatments that emerge from that perspective remain poor because they target the mental symptoms that are actually the consequences of the food deprivation that accompanies anorexia. On the other hand, a method that normalizes the disordered eating behavior of anorexics results in much better physiological, behavioral, and emotional outcomes. Copyright © 2015 Elsevier Ltd.

The evidence for the hypothesis that the poet Franz Kafka had suffered from an atypical anorexia nervosa is presented. Kafka was slim and underweight throughout his life and showed an ascetic attitude and abjuration of physical enjoyment and pleasure (fasting, vegetarianism, sexual abstinence, emphasis on physical fitness). The analysis is mainly based on Kafka's own descriptions in his letters, diaries, and literary work. Kafka was achievement oriented, reported many sadomasochistic fantasies, and had an anancastic (obsessive-compulsive) depressive personality. In addition there is evidence for a disturbed psychosexual and gender identity development. Our results concerning Kafka's psychopathology do not question his genius as a poet.

Anorexia represents a major problem for older persons leading to weight loss, sarcopenia, functional decline, and mortality. There is increasing information on the pathophysiological mechanisms that lead to anorexia. Increasing evidence has shown the importance of gastrointestinal hormones (ghrelin, cholecystokinin, and glucagon-like peptide) and adipokines in producing the anorexia of aging. Numerous neurotransmitters have been shown to be involved in this aging anorexia, but evidence in humans is lacking. The early recognition of anorexia of aging is important to allow intervention and prevent functional deterioration in older persons. Screening tests for anorexia have been developed. New approaches to managing anorexia are being tested.

Full Text Available Brainstem and hypothalamic orexigenic/anorexigenic networks are thought to maintain body weight homeostasis in response to hormonal and metabolic feedback from peripheral sites. This approach has not been successful in managing over- and underweight patients. It is suggested that concept of homeostasis has been misinterpreted; rather than exerting control, the brain permits eating in proportion to the amount of physical activity necessary to obtain food. In support, animal experiments have shown that while a hypothalamic orexigen excites eating when food is abundant, it inhibits eating and stimulates foraging when food is in short supply. As the physical price of food approaches zero, eating and body weight increase without constraints. Conversely, in anorexia nervosa body weight is homeostatically regulated, the high level of physical activity in anorexia is displaced hoarding for food that keeps body weight constantly low. A treatment based on this point of view, providing patients with computerized mealtime support to re-establish normal eating behavior, has brought 75% of patients with eating disorders into remission, reduced the rate of relapse to 10%, and eliminated mortality.

Full Text Available Prevalence of anorexia nervosa among women is 0,5%, whereas mortality related to this disorder amounts to 5–17%. Psychopathological structure of anorexia nervosa implies abnormalities of behavior as well as those of motivation and volition, thinking, perception and appreciation. In addition, mental abnormalities typical for this disorder are evident in regulation of emotions, specific personality traits and self-consciousness. The key psychopathological feature of patients with anorexia nervosa is a lack of cognitive and personal differentiation that calls forth impairments of self-concept and self-image. Anorexia nervosa should be differentiated from depression and schizophrenic spectrum disorders. Its etiology and pathogenesis are related both to hereditary and psychosocial factors. Of great importance are psychoendocrine abnormalities, however their role is still insufficiently elucidated.

Full Text Available Las fibras de mielina intraoculares se presentan desde el nacimiento y suelen localizarse alrededor de la papila. El síndrome de mielinización de las fibras nerviosas retinales fue descrito por Virchow por primera vez en 1856. Este aparece como parches estriados, blanco o blanco grisáceos con los bordes imprecisos y plumosos siguiendo una configuración coincidente con la distribución de las fibras nerviosas retinales. Se presenta una paciente femenina de 4 años que es traída a consulta por desviación del ojo derecho. En el examen oftalmológico se detecta una agudeza visual con corrección de 0,1 y la oftalmoscopia confirma la mielinización de las fibras nerviosas retinales. En estos pacientes se asocia frecuentemente la miopía y ambliopía. A pesar de los pobres resultados visuales y ante la ausencia de otras terapias disponibles existe tendencia a tratamiento agresivo para la ambliopía, aunque en la literatura esto es aún controversial.

Purpose of review Anorexia nervosa is associated with low bone mineral density (BMD), concerning for an increased risk of fractures, and decreased bone accrual in adolescents, concerning for suboptimal peak bone mass. This review discusses causes of impaired bone health in anorexia nervosa and potential therapeutic strategies. Recent findings Low BMD in anorexia nervosa is consequent to decreased lean mass, hypogonadism, low insulin-like growth factor-1 (IGF-1), relative hypercortisolemia and alterations in hormones impacted by energy availability. Weight gain causes some improvement in bone accrual, but not to the extent observed in controls, and vitamin D supplementation does not increase BMD. Oral estrogen is not effective in increasing BMD, likely from IGF-1 suppressive effects. In contrast, transdermal estrogen replacement is effective in increasing bone accrual in adolescents with anorexia nervosa, although not to the extent seen in controls. Recombinant human IGF-1 increases bone formation in adolescents, and with oral estrogen increases BMD in adults with anorexia nervosa. Bisphosphonates increase BMD in adults, but not in adolescents, and should be used cautiously given their long half-life. Summary Further investigation is necessary to explore therapies for low BMD in anorexia nervosa. Weight gain is to be encouraged. Transdermal estrogen in adolescents, and bisphosphonates in adults, have a potential therapeutic role. PMID:21897220

Anorexia nervosa (AN) is a condition of severe low weight that is associated with low bone mass, impaired bone structure and reduced bone strength, all of which contribute to increased fracture risk., Adolescents with AN have decreased rates of bone accrual compared with normal-weight controls, raising addition concerns of suboptimal peak bone mass and future bone health in this age group. Changes in lean mass and compartmental fat depots, hormonal alterations secondary to nutritional factors contribute to impaired bone metabolism in AN. The best strategy to improve bone density is to regain weight and menstrual function. Oral estrogen-progesterone combinations are not effective in increasing bone density in adults or adolescents with AN, and transdermal testosterone replacement is not effective in increasing bone density in adult women with AN. However, physiologic estrogen replacement as transdermal estradiol with cyclic progesterone does increase bone accrual rates in adolescents with AN to approximate that in normal-weight controls, leading to a maintenance of bone density Z-scores. A recent study has shown that risedronate increases bone density at the spine and hip in adult women with AN. However, bisphosphonates should be used with great caution in women of reproductive age given their long half-life and potential for teratogenicity, and should be considered only in patients with low bone density and clinically significant fractures when non-pharmacological therapies for weight gain are ineffective. Further studies are necessary to determine the best therapeutic strategies for low bone density in AN. PMID:24898127

Despite a high prevalence of menstrual irregularities, women with anorexia nervosa are becoming pregnant. The physical and psychological demands of pregnancy and motherhood can represent an immense challenge for women already struggling with the medical and psychological stress of an eating disorder. This article summarizes key issues related to reproduction in women with anorexia nervosa, highlighting the importance of preconception counseling, adequate gestational weight gain, and sufficient pre- and post-natal nutrition. Postpartum issues including eating disorder symptom relapse, weight loss, breastfeeding, and risk of perinatal depression and anxiety are also discussed. PMID:22003362

Todas las participantes completaron los siguientes instrumentos de auto-respuesta: FACES II, F-COPES, IPPA y el Cuestionario de Creencias Familiares. Los resultados demostraron que, en comparación con el grupo de mujeres sin patología alimentaria, las pacientes consideran a sus familias menos unidas y menos capaces de redefinir de una forma más aceptable las experiencias y situaciones de estrés. Sin embargo, consideran a sus familias más capaces de buscar y aceptar ayuda, y presentan más creencias familiares relacionadas con la responsabilidad individual/ auto-censura. En comparación con el grupo sin patología alimentaria, las pacientes parecen confiar menos en sus madres y amigos, parecen comunicarse menos con los amigos, y tienden a demostrar una mayor alienación en relación a la madre, al padre y a los amigos. De todas las variables en estudio, la alienación en relación a los amigos y a la madre, así como la mayor capacidad para buscar y aceptar ayuda fueron las variables más importantes para discriminar los grupos.

Anorexia nervosa and bulimia nervosa are serious psychiatric illnesses related to disordered eating and distorted body images. They both have significant medical complications associated with the weight loss and malnutrition of anorexia nervosa, as well as from the purging behaviors that characterize bulimia nervosa. No body system is spared from the adverse sequelae of these illnesses, especially as anorexia nervosa and bulimia nervosa become more severe and chronic. We review the medical complications that are associated with anorexia nervosa and bulimia nervosa, as well as the treatment for the complications. We also discuss the epidemiology and psychiatric comorbidities of these eating disorders. Copyright © 2016 Elsevier Inc. All rights reserved.

An association between anorexia nerviosa (AN) and low bone mass has been demonstrated. Bone loss associated with AN involves hormonal and nutritional impairments, though their exact contribution is not clearly established. We compared bone mass in AN patients with women of similar weight with no criteria for AN, and a third group of healthy, normal-weight, age-matched women. The study included forty-eight patients with AN, twenty-two healthy eumenorrhoeic women with low weight (LW group; BMI 18.5 kg/m2 (control group), all of similar age. We measured lean body mass, percentage fat mass, total bone mineral content (BMC) and bone mineral density in lumbar spine (BMD LS) and in total (tBMD). We measured anthropometric parameters, leptin and growth hormone. The control group had greater tBMD and BMD LS than the other groups, with no differences between the AN and LW groups. No differences were found in tBMD, BMD LS and total BMC between the restrictive (n 25) and binge-purge type (n 23) in AN patients. In AN, minimum weight (P = 0.002) and percentage fat mass (P = 0.02) explained BMD LS variation (r2 0.48) and minimum weight (r2 0.42; P = 0.002) for tBMD in stepwise regression analyses. In the LW group, BMI explained BMD LS (r2 0.72; P = 0.01) and tBMD (r2 0.57; P = 0.04). We concluded that patients with AN had similar BMD to healthy thin women. Anthropometric parameters could contribute more significantly than oestrogen deficiency in the achievement of peak bone mass in AN patients.

Full Text Available The aim of this study was to describe how young women living with self-identified anorexia narrate about their lives by blogging. Thirteen Swedish blogs were chosen and analyzed by means of qualitative content analysis. The results described falling ill, the illness itself, and the path to recovery. Low self-esteem, depressed state of mind, and self-destructive behavior were typical signs at the start of the illness. The women’s lives were characterized by a need for controlling their body by tormenting it and by the illness demanding all their concentration and energy. The women suffered from the feeling of being a disappointment to their family members. The illness was like an enemy that had to be defeated with the help of family members, health care professionals, and by means of therapy. A turning point occurred when the women felt at their worst or had tired of the illness and could concentrate on something other than their body and the eating disorder. Suffering from self-identified anorexia was described as experiencing low self-esteem. The illness took all of the women’s time and energy. For a turning point to be reached, the women needed support from family, friends, and health care professionals, including the use of distractions.

OBJECTIVE: This paper is a review on the topic of adolescent-onset anorexia nervosa. According to the literature, this disorder presents high morbidity and mortality, with increasing incidence over the last decades, thus enhancing the importance of scientific investigation on the subject. METHODS: The authors performed a non-systematic review of the related literature and also reported their clinical experience. RESULTS: Age and gender are important risk factors. The peak of incidence occurs in adolescence and the prevalence is 9 times higher in females. It was initially believed that anorexia nervosa manifested itself only in higher socioeconomic levels, which are more highly exposed to the demands of western beauty standards. More recent studies have identified similar incidence of this disorder also in lower socioeconomic levels, rural areas and Asian communities. The clinical features are: refusal to maintain weight at or above a minimal normal weight for age; high, intense fear of gaining weight or becoming fat, even though underweight; disturbance in the way of experiencing one s body weight or shape, and amenorrhea. The most common physical complications are similar to those of chronic malnutrition and depression is the main comorbidity. CONCLUSIONS: Treatment should be multidisciplinary, taking into account the plurality of etiological factors. Family therapy plays an important role, particularly when this disorder manifests itself during adolescence.

In common with individuals experiencing a number of disorders, people with anorexia nervosa report experiencing an internal 'voice'. The anorexic voice comments on the individual's eating, weight and shape and instructs the individual to restrict or compensate. However, the core characteristics of the anorexic voice are not known. This study aimed to develop a parsimonious model of the voice characteristics that are related to key features of eating disorder pathology and to determine whether patients with anorexia nervosa fall into groups with different voice experiences. The participants were 49 women with full diagnoses of anorexia nervosa. Each completed validated measures of the power and nature of their voice experience and of their responses to the voice. Different voice characteristics were associated with current body mass index, duration of disorder and eating cognitions. Two subgroups emerged, with 'weaker' and 'stronger' voice experiences. Those with stronger voices were characterized by having more negative eating attitudes, more severe compensatory behaviours, a longer duration of illness and a greater likelihood of having the binge-purge subtype of anorexia nervosa. The findings indicate that the anorexic voice is an important element of the psychopathology of anorexia nervosa. Addressing the anorexic voice might be helpful in enhancing outcomes of treatments for anorexia nervosa, but that conclusion might apply only to patients with more severe eating psychopathology. Copyright © 2016 John Wiley & Sons, Ltd. Experiences of an internal 'anorexic voice' are common in anorexia nervosa. Clinicians should consider the role of the voice when formulating eating pathology in anorexia nervosa, including how individuals perceive and relate to that voice.

Anorexia nervosa (AN), a psychiatric disorder predominantly affecting young women, is characterized by self-imposed chronic nutritional deprivation and distorted body image. AN is associated with a number of medical co-morbidities including low bone mass. The low bone mass in AN is due to an uncoupling of bone formation and bone resorption, which is the result of hormonal adaptations aimed at decreasing energy expenditure during periods of low energy intake. Importantly, the low bone mass in AN is associated with a significant risk of fractures and therefore treatments to prevent bone loss are critical. In this review, we discuss the hormonal determinants of low bone mass in AN and treatments that have been investigated in this population. PMID:24419863

There is great interest, supported by clinical experience, in the relationship between Eating Disorders (EDs) and psychiatric symptoms and diseases. The psychopathology of EDs is also referred to many risk and protective factors, and there is some evidence in the literature, also about genetic and neurobiological factors involved. EDs are often associated with pre-morbid psychiatric disorders, personality disorders, substance abuse, mood and anxiety disorders. The great amount of scientific articles dealing with the relationship between EDs and psychopathology confirms the complexity of these problems and the difficulties in diagnosis and treatment. The aim of this review is to examine and synthesize the recent scientific literature on this topic, in particular the complex relationship between Anorexia Nervosa (AN) and Neuropsychiatric Disorders.

Summary Anorexia nervosa (AN) is prevalent in adolescents and young adults, and endocrine changes include hypothalamic amenorrhea, a nutritionally acquired growth hormone resistance with low insulin like growth factor-1 (IGF-1), relative hypercortisolemia, decreases in leptin, insulin, amylin and incretins, and increases in ghrelin, PYY and adiponectin. These changes in turn have deleterious effects on bone, and may affect neurocognition, anxiety, depression and eating disorder psychopathology. Low bone density is particularly concerning; clinical fractures occur and changes in both bone microarchitecture and strength estimates have been reported. Recovery causes improvement of many, but not all, hormonal changes, and deficits in bone accrual may persist despite recovery. Physiologic, primarily transdermal, estrogen replacement increases bone density in adolescents, although catch-up is incomplete. In adults, oral estrogen co-administered with rhIGF-1 in one study, and bisphosphonates in another increased bone density, though not to normal. More studies are necessary to determine the optimal therapeutic approach in AN. PMID:24731664

Anorexia nervosa (AN) is classically defined as a condition in which an abnormally low body weight is associated with an intense fear of gaining weight and distorted cognitions regarding weight, shape, and drive for thinness. This article reviews recent evidences from physiology, genetics, epigenetics, and brain imaging which allow to consider AN as an abnormality of reward pathways or an attempt to preserve mental homeostasis. Special emphasis is put on ghrelino-resistance and the importance of orexigenic peptides of the lateral hypothalamus, the gut microbiota and a dysimmune disorder of neuropeptide signaling. Physiological processes, secondary to underlying, and premorbid vulnerability factors—the “pondero-nutritional-feeding basements”- are also discussed. PMID:27445651

The aim of this study was to investigate preferential information processing style in Eating Disorders (ED). We compared the performance of participants with EDs against healthy controls in a task that measures cognitive style (reflection-impulsivity) and cognitive efficiency (inefficient-efficient). Sixty non-medicated female participants (healthy controls n=26, anorexia nervosa n=20, bulimia nervosa n=14) took part in the Matching Familiar Figures Test (MFFT), a difficult visual search paradigm with high response uncertainty. Participants with anorexia scored significantly higher on the efficiency dimension score than the control group. No significant differences were found across groups on the dimension 'reflection-impulsivity'. Participants with anorexia are more efficient (quicker response latencies in conjunction with fewer errors) in this visual search task that requires an analytic approach. This supports the hypothesis that individuals with anorexia have a positive bias toward local detail processing, indicative of weak central coherence.

The Anorexia Bulimia Inventory, a recently developed self-report questionnaire for the assessment of eating disorders, addresses two major limitations found in existing self-report eating disorder inventories. First, it comprehensively assesses the diagnostic symptoms of both bulimia and anorexia nervosa; and second, it assesses the frequently cooccurring problem areas (e.g., depression, anergia) that may be targeted in treatment planning for eating disorders. Although initial research on the...

Objective In this review, based on recent advances in cognitive neuroscience, the author presents a formulation in which the marked persistence of anorexia nervosa can be usefully understood as a well-ingrained maladaptive habit. Method The author reviewed the relevant literature on the development and course of anorexia nervosa and interpreted critical features in light of developments in cognitive neuroscience. Results Anorexia nervosa is a well characterized disorder with remarkable persistence both across history and among affected individuals. Food restriction, the salient behavioral feature of the disorder, often begins innocently but gradually takes on a life of its own. Over time, it becomes highly entrenched and resistant to change through either psychological or pharmacological treatment. Cognitive neuroscience has described two related but distinct processes that underlie the acquisition of new patterns of behavior, namely, action-outcome and stimulus-response learning. It is likely that both processes are engaged in the development of anorexia nervosa and that stimulus-response learning (that is, habit formation) is critical to the persistence of the dieting behavior. Conclusions The formulation of the dieting behavior characteristic of anorexia nervosa as a well-entrenched habit provides a basis for understanding the striking persistence of this disorder. This model helps explain the resistance of anorexia nervosa to interventions that have established efficacy in related disorders and implies that addressing the dieting behavior is critical, especially early in the course of the illness, before it has become ingrained.

To investigate the risk factors for anorexia in children, and to reduce the prevalence of anorexia in children. A questionnaire survey and a case-control study were used to collect the general information of 150 children with anorexia (case group) and 150 normal children (control group). Univariate analysis and multivariate logistic stepwise regression analysis were performed to identify the risk factors for anorexia in children. The results of the univariate analysis showed significant differences between the case and control groups in the age in months when supplementary food were added, feeding pattern, whether they liked meat, vegetables and salty food, whether they often took snacks and beverages, whether they liked to play while eating, and whether their parents asked them to eat food on time (Panorexia in children. Liking of meat (OR=0.093) and vegetables (OR=0.272) and eating on time required by parents (OR=0.079) were protective factors against anorexia in children. Timely addition of supplementary food, a proper diet, and development of children's proper eating and living habits can reduce the incidence of anorexia in children.
Full Text Available Theories of anorexia nervosa have mainly been dominated by psychiatry and concentrate upon its physiological aspects, both in diagnosis and treatment. This has led to a search for organic causes behind anorectic conditions, instead of seeing it as molded and shaped both by the individual and the socio-cultural context. This "medicalisation" has been an impediment to a more complete conceptualisation of the experience of discipline and of the ascetic modes of action in anorexia. The intension is to approach anorexia as lived process. The focus is not in explaining what cause anorexia, but is centered on the contents of living experience as such. Thus, the author proposes a phenomenological approach to anorexia as a methodological alternative compared to the dominant medico-psychological approaches to anorexia of today. If we consider the body of an anorectic person as an intersection in which the subject's relationship to social reality will be materialized and verified, we are able to see first how accurate a picture of the dual meanings, double bindings and paradoxical commitments of our present culture and its relation to a woman's body anorexia will draw up. Also, because the fact is that anorexia is a predominantly "women's" illness we have to take in account that the construction of subjectivity and in this context the construction of a lived anorectic experience of discipline, is not a gender-neutral process.

No epidemiologic survey examining eating disorders in Japan has been done at a national level since 1992. The prevalence of anorexia nervosa, as assessed by questionnaires to hospitals, is thought to be underestimated because patients with anorexia nervosa tend to avoid consultations. In conformity with the School Health and Safety Act of Japan, schools are required to have physicians perform a medical examination of students every year. The teachers in charge of health education and school physicians determine the height, weight, and health condition, and examine the medical records of each student. Therefore, we as members of the Survey Committee for Eating Disorders of the Japanese Ministry of Health, Labour, and Welfare conducted an epidemiologic survey using questionnaires sent to schools in seven prefectures to determine the current prevalence of anorexia nervosa among adolescents. We sent a questionnaire to elementary, junior high, and senior high schools. Questionnaires contained items on the number of students, patients with anorexia nervosa in each grade who were diagnosed by specialists, and students who the school physician strongly suspected to have anorexia nervosa but who did not undergo a clinical examination in a medical institution. We found patients of both sexes with anorexia nervosa aged 9-10 years in elementary schools. The point prevalence of anorexia nervosa for girls, including strongly suspected cases, in the three grades of junior high school and three grades of senior high school were 0-0.17 %, 0-0.21 %, 0.17-0.40 %, 0.05-0.56 %, 0.17-0.42 % and 0.09-0.43 %, respectively. We also confirmed a prominent sex difference in the prevalence of anorexia nervosa. The prevalence of boys was one third that of girls in some prefectures. One third to one half of diagnosed and strongly suspected students with anorexia nervosa had not received medical consultation or treatment. Although the prevalence of anorexia nervosa had regional differences

Full Text Available Sportler aus Sportarten, in denen ein geringes Körpergewicht vorteilhaft für die Leistungsfähigkeit ist, gehen oft durch Reduktion der Kalorienzufuhr bei gleichzeitig hohem Energieverbrauch ein erhebliches Energiedefizit ein. Dabei kommt es häufig zu Essstörungen, für die in besonders gefährdeten Sportarten eine Prävalenz von bis zu 80 % berichtet wird und die sich zur Anorexia nervosa oder Bulimia nervosa entwickeln können. Als Folge des Energiedefizits können Konzentrationsänderungen von Stoffwechselhormonen, Störungen der Hypothalamus- Hypophysen-Gonaden-Achse und des Knochenstoffwechsels mit Abnahme der Knochendichte bis hin zur Osteoporose und einem erhöhten Risiko für Stressfrakturen beobachtet werden. Der Symptomkomplex aus Essstörung, sekundärer Amenorrhö und verminderter Knochendichte wird auch als Female Athlete Triad bezeichnet, wobei in den vergangenen Jahren als viertes Symptom eine endotheliale Dysfunktion beschrieben wurde. Die effektivste Therapie ist das Herstellen eines dauerhaften Energiegleichgewichts, wofür eine tägliche Energieverfügbarkeit von mindestens 30 kcal/kg Magergewicht erforderlich ist. Eine hierdurch bedingte Gewichtszunahme kann den Sportlern nicht immer vermittelt werden, weshalb durch eine sorgfältig zusammengestellte Ernährung zumindest auf eine ausreichende Zufuhr von Kalzium, Vitamin D und Eiweiß geachtet werden muss. Oftmals ist die zusätzliche Verabreichung von Kalzium- und Vitamin-D-Präparaten angezeigt sowie eine Östrogensubstitution. Allerdings ist ein orales Kontrazeptivum als einzige Therapie anders als früher angenommen nicht ausreichend zur Behandlung oder Vermeidung einer Knochendichteminderung. Zur Prävention der Anorexia athletica sind die Aufklärung der Sportler, Trainer und Betreuer und ein Screening im Rahmen von Sporttauglichkeitsuntersuchungen, vor allem aber auch strukturelle Maßnahmen durch die Sportfachverbände erforderlich (wie zum Beispiel im

A follow-up study has been recently conducted in 20 female patients with severe anorexia nervosa who had undergone stationary psychotherapeutic treatment at our clinic 8-16 years ago. Whilst according to our findings the prognosis for anorexia nervosa still remains poor, it does not seem quite so hopeless as is frequently presumed. Out of the 20 patients followed up, 5 now have chronic anorexia nervosa and in 2 cases transition to an endogenous psychosis has occurred (schizophrenia simplex with chronified anorexia in one, and endogenous depression after improvement of anorexia in the other case). 1 patient died in the interval between observations as a result of her anorexia. The general results of our investigation roughly confirm the rule-of-thumb predictions for many psychotherapeutic treatments of neurotic diseases, i.e. 1/3 unimproved, 1/3 improved, 1/3 cured. Although free from illness, the majority of the patients must be described as conspicuous within the norm. The typical personal characteristics of the anorectic are maintained, their weight remains below normal level, and they suffer from eating problems. According to our investigation a positive prognosis correlates with onset of the illness before the age of 18, absence of laxative abuse, and subsequent marriage, whereas premature interruption of the treatment with return to the parental home proves to have a negative effect. In apparent contradiction to the persistence of the characteristic anorectic features is the evidence that out of the 20 patients in question 12 married and 8 had children. On the other hand, the fact that during the interval between observations 4 patients relapsed into severe anorexia in connexion with engagement or pregnancy indicates that acceptance of a mature female or maternal role often remains a problem. Of gynecologic interest is the fact that long-lasting secondary amenorrhea (up to 10 years, with an average of 5 years) has not led to fertility problems for any of the

Anorexia nervosa (AN) has the highest mortality rate of all psychiatric illnesses due to the widespread organ dysfunction caused by the underlying severe malnutrition. Starvation causes hepatocyte injury and death leading to a rise in aminotransferases. Malnutrition-induced hepatitis is common among individuals with AN especially as body mass index decreases. Acute liver failure associated with coagulopathy and encephalopathy can rarely occur. Liver enzymes may also less commonly increase as part of the refeeding process due to hepatic steatosis and can be distinguished from starvation hepatitis by the finding of a fatty liver on ultrasonography. Individuals with AN and starvation-induced hepatitis are at increased risk of hypoglycemia due to depleted glycogen stores and impaired gluconeogenesis. Gastroenterology and hepatology consultations are often requested when patients with AN and signs of hepatitis are hospitalized. It should be noted that additional laboratory testing, imaging, or liver biopsy all have low diagnostic yield, are costly, and potentially invasive, therefore, not generally recommended for diagnostic purposes. While the hepatitis of AN can reach severe levels, a supervised increase in caloric intake and a return to a healthy body weight often quickly lead to normalization of elevated aminotransferases caused by starvation.

Patients with anorexia nervosa (AN) show extreme dieting weight loss, hyperactivity, depression/anxiety, self-control, and behavioral impulsivity. 5-Hydroxytryptamine (5-HT; serotonin) is involved in almost all the behavioral changes observed in AN patients. Both genetic and environmental factors contribute toward the pathogenesis of AN. It is a frequent disorder among adolescent girls and young women and starts as an attempt to lose weight to look beautiful and attractive. Failure to see the turning point when fasting becomes unreasonable leads to malnutrition and AN. Tryptophan, the precursor of serotonin and an essential amino acid, is only available in the diet. It is therefore likely that excessive diet restriction and malnutrition decrease brain serotonin stores because the precursor is less available to the rate-limiting enzyme of 5-HT biosynthesis, which normally exists unsaturated with its substrate. Evidence shows that diet restriction-induced exaggerated feedback control over 5-HT synthesis and the smaller availability of tryptophan decreases serotonin neurotransmission at postsynaptic sites, leading to hyperactivity, depression, and behavioral impulsivity. A compensatory upregulation of postsynaptic 5-HT-1A receptors and hypophagic serotonin receptors may be involved in anxiety and suppression of appetite. It is suggested that tryptophan supplementation may improve pharmacotherapy in AN.

Full Text Available A serious problem faced by clinicians treating anorexia nervosa is the egosyntonic nature of the illness, wherein individuals with anorexia nervosa value their disorder, thereby hindering motivation for recovery and engagement with treatment. The objective of this review article is to elucidate the nature of egosyntonicity in anorexia nervosa, reviewing both qualitative and quantitative research pertaining to this topic, and, importantly, to present methods to overcome this impediment to recovery in anorexia nervosa treatment. The authors elucidate functions of anorexia nervosa for patients, both within psychological and social spheres, as well as highlight the detrimental effect of egosyntonicity in terms of illness severity and motivation for recovery. The final part of the paper contains suggestions as to methods of bypassing pitfalls linked with the influence of the egosyntonic nature of anorexia nervosa within a treatment setting, as well as an examination of three current treatments (enhanced cognitive-behavioral therapy for eating disorders, Maudsley Model of Anorexia Nervosa Treatment for Adults, and Specialist Supportive Clinical Management in terms of the degree to which they target egosyntonicity.

Since medieval times, an association between religiosity and anorexia nervosa has been suggested, but few systematic studies exist. This study examines in a nationwide setting whether personal or family religiosity is associated with lifetime anorexia nervosa among women in adolescence and early adulthood. Women (N = 2,825) from the 1975 to 1979 birth cohorts of Finnish twins were screened for lifetime DSM-5 anorexia nervosa (N = 92). Parental religiosity was assessed by self-report when the women were aged 16 years. The women self-reported their religiosity at ages 16 and 22 to 27 years. Parental religiosity did not increase the risk of lifetime anorexia nervosa, and neither did religiosity of the women themselves in adolescence. In early adulthood, a J-shaped curve was compatible with the data, indicating increased risk both at low and high levels of religiosity, but this result was statistically non-significant. Religiosity was weakly negatively correlated with body dissatisfaction. There was some suggestive evidence for socioregional variation in the association of religiosity with lifetime anorexia nervosa. In this first population study to directly address religiosity and anorexia nervosa, no evidence was found for a significant association of religiosity with anorexia nervosa either at the personal or family level. Some regional differences are possible. A modest protective association of religiosity with body dissatisfaction is also possible. Despite compelling case descriptions of "holy anorexia," religiosity does not appear to be a central factor in the development of anorexia nervosa in Finland, a highly secularized Christian country. © 2017 Wiley Periodicals, Inc.
Full Text Available Compelling data demonstrate that inflammation-associated anorexia directly results from the action of pro-inflammatory factors, primarily cytokines and prostaglandins E2, on the nervous system. For instance, the aforementioned pro-inflammatory factors can stimulate the activity of peripheral sensory neurons, and induce their own de novo synthesis and release into the brain parenchyma and cerebrospinal fluid. Ultimately, it results in the mobilization of a specific neural circuit that shuts down appetite. The present article describes the different cell groups and neurotransmitters involved in inflammation-associated anorexia and examines how they interact with neural systems regulating feeding such as the melanocortin system. A better understanding of the neurobiological mechanisms underlying inflammation-associated anorexia will help to develop appetite stimulants for cancer and AIDS patients.

Activity-based anorexia (ABA) consists of a procedure that involves the simultaneous exposure of animals to a restricted feeding schedule, while free access is allowed to an activity wheel. Under these conditions, animals show a progressive increase in wheel running, a reduced efficiency in food intake to compensate for their increased activity, and a severe progression of weight loss. Due to the parallelism with the clinical manifestations of anorexia nervosa including increased activity, reduced food intake and severe weight loss, the ABA procedure has been proposed as the best analog of human anorexia nervosa (AN). Thus, ABA research could both allow a better understanding of the mechanisms underlying AN and generate useful leads for treatment development in AN. Copyright © 2014 John Wiley & Sons, Inc.
The aetiology, assessment and treatment of anorexia nervosa are reviewed in the light of the classical accounts of Morton, Lasègue and Gull. The core symptoms are deliberate weight loss, disturbed body image and amenorrhoea, and complications may include cardiac failure, electrolyte disturbances, hypothermia and osteoporosis. Common clinical findings are described. Disturbed brain serotonin activity is implicated in the aetiology of anorexia nervosa, but there is little support for the use of pharmacological treatments. Psychological theories of aetiology are discussed with reference to Bruch, Crisp, Palazzoli and Minuchin: the common theme is the reaction of the patient and her family to the physical and social changes of puberty. Individual and/or family psychotherapy is seen as central to the treatment of anorexia nervosa, and the relevant clinical research is reviewed. The roles of general practitioners, general psychiatrists and eating disorder specialists are discussed in the light of recent consensus treatment guidelines.

There are some studies in the literature about the feeding behavior and masticatory process in patients with feeding disorders; however, it is not very well known if there are alterations in oral-pharyngeal swallowing dynamics in subjects with anorexia nervosa. To evaluate the oral and pharyngeal bolus transit in patients with anorexia nervosa. The study was conducted with 8 individuals clinically diagnosed and in treatment for restricting-type anorexia nervosa (seven women and one man), and 14 healthy individuals with no digestive or neurological symptoms (10 women, 4 men). Swallows were evaluated by videofluoroscopy with three swallows of 5 mL liquid bolus and three swallows of 5 mL paste bolus consistency, given in a random sequence. The participants were asked after each swallow about the sensation of the bolus passage. In the analysis of oral-pharyngeal transit duration, the mean duration of pharyngeal transit with paste bolus in patients with anorexia was shorter than in healthy volunteers (P=0.02). In the duration of movement of the hyoid bone, longer movement was observed in anorexia than in healthy volunteers with liquid bolus (P=0.01). With liquid bolus, five (62.5%) patients and one (7.1%) control had sensation of the bolus passage (Panorexia nervosa, although the results suggest that pharyngeal transit has shorter duration than that seen in healthy volunteers and the hyoid movement duration is longer in patients than in healthy volunteers. Fast pharyngeal transit may be the cause of bolus transit perception in patients with anorexia nervosa.

The anorexia that accompanies the drinking of hypertonic saline (DE-anorexia) is a critical adaptive behavioral mechanism that helps protect the integrity of fluid compartments during extended periods of cellular dehydration. Feeding is rapidly reinstated once drinking water is made available again. The relative simplicity and reproducibility of these behaviors makes DE-anorexia a very useful model for investigating how the various neural networks that control ingestive behaviors first suppress and then reinstate feeding. We show that DE-anorexia develops primarily because the mechanisms that terminate ongoing meals are upregulated in such a way as to significantly reduce meal size. At the same time however, signals generated by the ensuing negative energy balance appropriately activate neural mechanisms that can increase food intake. But as the output from these two competing processes is integrated, the net result is an increasing reduction of nocturnal food intake, despite the fact that spontaneous meals are initiated with the same frequency as in control animals. Furthermore, hypothalamic NPY injections also stimulate feeding in DE-anorexic animals with the same latency as controls, but again meals are prematurely terminated. Comparing Fos expression patterns across the brain following 2-deoxyglucose administration to control and DE-anorexic animals implicates neurons in the descending part of the parvicellular paraventricular nucleus of the hypothalamus and the lateral hypothalamic areas as key components of the networks that control DE-anorexia. Finally, DE-anorexia generates multiple inhibitory processes to suppress feeding. These are differentially disengaged once drinking water is reinstated.

Full Text Available Abstract Background In spite of the role of some psychosomatic factors as alexithymia, mood intolerance, and somatization in both pathogenesis and maintenance of anorexia nervosa (AN, few studies have investigated the prevalence of psychosomatic syndromes in AN. The aim of this study was to use the Diagnostic Criteria for Psychosomatic Research (DCPR to assess psychosomatic syndromes in AN and to evaluate if psychosomatic syndromes could identify subgroups of AN patients. Methods 108 AN inpatients (76 AN restricting subtype, AN-R, and 32 AN binge-purging subtype, AN-BP were consecutively recruited and psychosomatic syndromes were diagnosed with the Structured Interview for DCPR. Participants were asked to complete psychometric tests: Body Shape Questionnaire, Beck Depression Inventory, Eating Disorder Inventory–2, and Temperament and Character Inventory. Data were submitted to cluster analysis. Results Illness denial (63% and alexithymia (54.6% resulted to be the most common syndromes in our sample. Cluster analysis identified three groups: moderate psychosomatic group (49%, somatization group (26%, and severe psychosomatic group (25%. The first group was mainly represented by AN-R patients reporting often only illness denial and alexithymia as DCPR syndromes. The second group showed more severe eating and depressive symptomatology and frequently DCPR syndromes of the somatization cluster. Thanatophobia DCPR syndrome was also represented in this group. The third group reported longer duration of illness and DCPR syndromes were highly represented; in particular, all patients were found to show the alexithymia DCPR syndrome. Conclusions These results highlight the need of a deep assessment of psychosomatic syndromes in AN. Psychosomatic syndromes correlated differently with both severity of eating symptomatology and duration of illness: therefore, DCPR could be effective to achieve tailored treatments.

Pro-anorexia communities exist online and encourage harmful weight loss and weight control practices, often through emotional content that enforces social ties within these communities. User-generated responses to videos that directly oppose pro-anorexia communities have not yet been researched in depth. The aim was to study emotional reactions to pro-anorexia and anti-pro-anorexia online content on YouTube using sentiment analysis. Using the 50 most popular YouTube pro-anorexia and anti-pro-anorexia user channels as a starting point, we gathered data on users, their videos, and their commentators. A total of 395 anorexia videos and 12,161 comments were analyzed using positive and negative sentiments and ratings submitted by the viewers of the videos. The emotional information was automatically extracted with an automatic sentiment detection tool whose reliability was tested with human coders. Ordinary least squares regression models were used to estimate the strength of sentiments. The models controlled for the number of video views and comments, number of months the video had been on YouTube, duration of the video, uploader's activity as a video commentator, and uploader's physical location by country. The 395 videos had more than 6 million views and comments by almost 8000 users. Anti-pro-anorexia video comments expressed more positive sentiments on a scale of 1 to 5 (adjusted prediction [AP] 2.15, 95% CI 2.11-2.19) than did those of pro-anorexia videos (AP 2.02, 95% CI 1.98-2.06). Anti-pro-anorexia videos also received more likes (AP 181.02, 95% CI 155.19-206.85) than pro-anorexia videos (AP 31.22, 95% CI 31.22-37.81). Negative sentiments and video dislikes were equally distributed in responses to both pro-anorexia and anti-pro-anorexia videos. Despite pro-anorexia content being widespread on YouTube, videos promoting help for anorexia and opposing the pro-anorexia community were more popular, gaining more positive feedback and comments than pro-anorexia videos

Although schizophrenia and anorexia nervosa are seemingly very distinct psychiatric disorders, their symptoms are connected by various types of relationships. The present article reviews the literature and recapitulates the views of various authors on the links between these two disorders. Symptoms of anorexia may 1) precede the onset of psychosis; 2) evolve in its active phase or more rarely manifest in remission; and, conversely, 3) psychotic symptoms may occur transiently in the course of anorexia nervosa. When anorexia precedes the manifestation of psychosis, symptoms of anorexia can be treated as a component of the prodromal phase of schizophrenia. Another possibility of co-existence of a psychosis (e.g., schizophrenia) with anorexia is when the eating disorder syndrome manifests at the same time as the full-blown psychotic syndrome. In such cases, when the symptoms of the two disorders occur simultaneously, it is often difficult to say whether the patient is suffering from schizophrenia, in the course of which anorexia has arisen secondary to psychotic symptoms or whether he/she is suffering from anorexia during which he/she has developed psychotic symptoms, usually thematically associated with eating. Studies published so far, mainly case reports, point to the complex nature of the interrelationships between schizophrenia and anorexia nervosa. Further research is needed to conclusively explain the relationships between psychotic disorders and anorexia nervosa, which would allow physicians to use more effective methods of treatment in this group of patients.

As anorexia patients always go to the psychiatric clinic, little is concerned about the occurrence of sinus bradycardia in these patients for cardiologists and psychiatrists. The aim of this paper is to discuss the relationship between anorexia and sinus bradycardia, and the feature analysis, differential diagnosis and therapeutic principles of this type of sinus bradycardia. We report a case of sinus bradycardia in an anorexia patient with the clinical manifestations, laboratory exams, auxiliary exams, therapeutic methods, and her prognosis, who was admitted to Peking University Third Hospital recently. The patient was a 19-year-old female, who had the manifestation of anorexia. She lost obvious weight in a short time (about 15 kg in 6 months), and her body mass index was 14.8 kg/m(2). The patient felt apparent palpitation, chest depression and short breath, without dizziness, amaurosis or unconsciousness. Vitals on presentation were notable for hypotension, and bradycardia. The initial exam was significant for emaciation, but without lethargy or lower extremity edema. The electrocardiogram showed sinus bradycardia with her heart rate being 32 beats per minute. The laboratory work -up revealed her normal blood routine, electrolytes and liver function. But in her thyroid function test, the free thyroid (FT) hormones 3 was 0.91 ng/L (2.3-4.2 ng/L),and FT4 was 8.2 ng/L (8.9-18.0 ng/L), which were all lower; yet the thyroid stimulating hormone (TSH) was normal 1.48 IU/mL (0.55-4.78 IU/mL). Ultrasound revealed her normal thyroid. Anorexia is an eating disorder characterized by extremely low body weight, fear of gaining weight or distorted perception of body image, and amenorrhea. Anorexia patients who lose weight apparently in short time enhance the excitability of the parasympathetic nerve, and inhibit the sympathetic nerve which lead to the appearance of sinus bradycardia, and functional abnormalities of multiple systems such as hypothyroidism. But this kind of sinus

Full Text Available The eating disorder that generates the highest death rate is that of anorexia nervosa, and current treatment is a combination of equalization of somatic state and patient education. Moreover, psychical symptoms occurring in the course of anorexia nervosa are thought to have a crucial influence on the course of the disease. Hence, in medical literature, the effectiveness of psychotherapeutic interventions is also widely described. Still, the implementation of appropriate psychopharmacology is now considered an additional method of treatment, rather than a therapy of choice. Yet, in spite of many years of research, there are no absolute recommendations given, nor are instructions within the scope of psychopharmacological treatment proffered, although the selection of psychopharmacological items must respect both the patient’s psychic and somatic states. In recent years, the popularity of psychopharmacological treatment has increased; therefore, we feel that it is justified to present the latest scientific information in this respect.
This study is based on the hypothesis that there is a connexion between the condition of Anorexia nervosa and factors of family socialization. The empirical examination of this assumption was carried out using the hospital records of 51 female patients treated for Anorexia nervosa in the Psychiatric University Hospital Göttingen from the period of 1967 to 1973. The family structure was investigated under the following context: 1) family constellation, 2) socioeconomic factors, 3) interactional patterns. At first sight these families have a normally disturbuted family constellation, a stable and accepted social status together with traditional social values. However, disturbed parental and matrimonial relationships in fluence the family attitudes in such a way as to enhance these behavior patterns associated with high performance and pseudo-solidarity. This complex family structure effects the anorexic patients such that--in an interactional view--an inbalance of ego identity arises and a adolescence crisis occurs.
This article draws on a review of Megan Warin’s 2010 book, Abject Relations: Everyday Worlds of Anorexia, to discuss the ways in which a feminist ethnographic approach might disrupt dominant cultural narratives of eating disorders and embodiment. My argument draws on feminist work on figuration and ‘body image’ to discuss how the anorexic body becomes a figure of abjection, both in media images and in popular feminist discourse. I examine how cultural narratives and images are pathologically ...

Within the core of capitalist discourse, some contemporary symptoms, anorexia and drug addiction, are taken into consideration from the clinic of the real. This is a new lacanian-oriented clinic in psychoanalysis that takes over from the clinic of the symbolic, which has essentially been Freud’s clinic, exceeding the limits in the era of hypermodernity. Drug addict’s pressure to consume the object drug contrasts with a radical negative of the anorexic persons who consume themselves. // Sobre ...

Context: Anorexia nervosa is a primary psychiatric disorder with serious endocrine consequences, including dysregulation of the gonadal, adrenal, and GH axes, and severe bone loss. This Update reviews recent advances in the understanding of the endocrine dysregulation observed in this state of chronic starvation, as well as the mechanisms underlying the disease itself. Evidence Acquisition: Findings of this update are based on a PubMed search and the author's knowledge of this field. Evidence Synthesis: Recent studies have provided insights into the mechanisms underlying endocrine dysregulation in states of chronic starvation as well as the etiology of anorexia nervosa itself. This includes a more complex understanding of the pathophysiologic bases of hypogonadism, hypercortisolemia, GH resistance, appetite regulation, and bone loss. Nevertheless, the etiology of the disease remains largely unknown, and effective therapies for the endocrine complications and for the disease itself are lacking. Conclusions: Despite significant progress in the field, further research is needed to elucidate the mechanisms underlying the development of anorexia nervosa and its endocrine complications. Such investigations promise to yield important advances in the therapeutic approach to this disease as well as to the understanding of the regulation of endocrine function, skeletal biology, and appetite regulation.

Anorexia nervosa (AN) is a relatively common disorder, especially in adolescent and young adult women. The lifetime prevalence of AN in females ranges from 1.2 to 2.2%. The prevalence in males is 10-times lower. The condition is associated with a high risk of chronic course and poor prognosis in terms of treatment and the risk of death. Longer follow-up periods seemed to correspond with increased improvement rates and increased mortality. Onset of the disorder during adolescence is associated with better prognosis. It is reported that as much as 70% to over 80% of patients in this age group achieve remission. Worse outcomes are observed in patients who required hospitalization and in adults. Recent studies indicate improved prognosis for cure and lower mortality rates than previously reported. However, the recovery can take several years and AN is associated with high risk of developing other psychiatric disorders during the patients' lifetime, even after recovery from AN (mainly: affective disorders, anxiety disorders, obsessive-compulsive disorders, substance abuse disorders). Studies indicate that bulimic symptoms often occur in the course of anorexia nervosa (especially within 2-3 years from the onset of AN). The authors present a review of literature on the course, comorbidity, mortality, and prognostic factors in AN. Better knowledge of the course of anorexia can contribute to more realistic expectations of the pace of symptomatic improvement, as well as to a creation of therapeutic programs which are better adapted to the needs of the patients.

Reconhecida como a base para ocorrências místicas na Idade Média, foi entendida como uma apresentação histérica no século XVII, para tornar-se, logo em seguida, objeto das indagações freudianas. Discute-se a anorexia como uma apresentação da estrutura histérica, aqui abordada a partir dos conceitos freudianos sobre histeria, Édipo e feminino, e considerando-se o corpo físico como um mero suporte para articulações simbólicas. Para Freud, a anorexia nervosa seria um quadro pelo qual a histérica exprime sua aversão à sexualidade.

Involuntary treatment of psychiatric disorders has always been controversial; this is especially true for eating disorders. Patients with anorexia nervosa of life threatening severity frequently refuse psychiatric hospitalization. Ambivalence toward treatment is characteristic of eating disorders and patients are often admitted to inpatient programs under pressure from family and doctors. In this article, we report research on the positive or negative impact of involuntary admission in the treatment of eating disorders, its application and effectiveness as well as the adverse consequences of coercive treatment in eating disorders. A literature review was done. From a total of 134 publications which were retrieved from the literature search, 50 studies were directly relevant to the scope of this review and fulfilled all inclusion criteria. There are trends and arguments for both sides; for and against involuntary treatment in anorexia nervosa. The scientific literature so far is inconclusive, although in the short term, involuntary hospitalization has benefits. This review has also shown that involuntary hospitalization can have adverse long-term consequences for the patient-therapist allegiance. We conclude that in some cases, involuntary treatment can save lives of young patients with anorexia nervosa; however, in other cases, it can break the psychotherapeutic relationship and make the patient abandon treatment. It is the clinician who has to decide for whom and when to approve involuntary treatment or not. Copyright © 2015 Elsevier Ltd. All rights reserved.

Mild pancreatitis has been reported as a consequence of anorexia nervosa, bulimia nervosa, or what has been termed the "dietary chaos syndrome". Either chronic malnutrition, or refeeding after periods of malnutrition, may precipitate acute pancreatitis through several pathogenetic mechanisms. A 26-year-old woman with a ten-year history of anorexia and bulimia presented with a third episode of acute pancreatitis in three months. The patient had been abstinent from alcohol for many years. Imaging studies during all three admissions failed to identify any biliary disease, including gallstones or biliary sludge. A cholecystectomy was performed, with a normal intraoperative cholangiogram, and no abnormalities on pathologic examination of the gallbladder and bile. The patient was discharged on hospital day 10 with no pain, and she has begun to return to regular eating habits. Pancreatitis has not recurred after 6 months of follow up. We have identified 14 cases in the literature of acute pancreatitis associated with anorexia or bulimia. In the absence of evidence for gallstone, alcohol or metabolic etiologies, eating disorders may contribute to the pathophysiology of some idiopathic cases of pancreatitis.

This paper turns upside-down the commonly held assumption that anorexia nervosa is inherently destructive or counter-productive. The author delves beneath the façade of anorexia's main symptom, self-starvation, to explore what refusing to eat accomplishes, psychically, for the sufferer. Featured in this paper are the clinical reflections of contemporary child analyst Adam Phillips who argues that symptoms, such as those in anorexia, are "experiments in living." In his view, anorexia is a particular way of testing the environment for its capacity to withstand and satisfy one's desires. Working also with the notion that anorexia is an attempt at compensation for traumatic loss or affective rupture, attention is drawn to both the inter-personal and intra-personal contexts within which self-starvation is pursued. Importantly, this approach recognizes that responses by those around the anorexic individual affect the conditions within which possibilities for recovery are made.

Full Text Available Dysfunctional social reward and social orienting attend a variety of neuropsychiatric disorders including autism, schizophrenia, social anxiety, and psychopathy. Here we show that similar social reward and attention dysfunction attend anorexia nervosa, a disorder defined by avoidance of food and extreme weight loss. We measured the implicit reward value of social stimuli for female participants with (n=11 and without (n=11 anorexia nervosa using an econometric choice task and also tracked gaze patterns during free viewing of images of female faces and bodies. As predicted, the reward value of viewing bodies varied inversely with observed body weight for women with anorexia but not neurotypical women, in contrast with their explicit ratings of attractiveness. Surprisingly, women with anorexia nervosa, unlike neurotypical women, did not find female faces rewarding and avoided looking at both the face and eyes—independent of observed body weight. These findings demonstrate comorbid dysfunction in the neural circuits mediating gustatory and social reward in anorexia nervosa.

By studying anorexia nervosa with an Integrated Inventory and the quality and the quantity of sleep applying Hauri's scale for the analysis of dream contents, the sleeping habits of 50 anorexic patients who were under treatment have been studied. The results show that sleep in these patients is similar and sometimes better in quantity and quality than those in the control group. Their dreams are characterized by an almost total absence of sexual, aggressive and alimentary contents, and that reality, active participation, unpleasant feelings and sensory-perceptive elements are predominant.

Extremes of eating disorders (ED) have become prevalent in both developed and developing countries. Available therapies, though largely effective, fail in a substantial number of patients and carry considerable side effects. Morbid obesity and anorexia nervosa (AN) represent important causes of morbidity and mortality among young adults. Morbid obesity affects disproportionate numbers of children. AN is also important for its high mortality in young adults. The challenges of effectively treating AN are well recognized. In this article, important aspects of ED are reviewed in detail and novel approaches to the treatment of ED are proposed. Copyright © 2014 Elsevier Inc. All rights reserved.

The recovery of Syrian hamsters after split dose application (interval 11 days) was studied on the basis of the weight response and of food uptake. Two periods of weight loss and anorexia can be distinguished, an early one immediately after irradiation and a secondary one 6-10 days later. The secondary response is a function of the radiation dose and allows to distinguish survivors from non-survivors, since it is much more pronounced and longerlasting in the latter than in the former. The first response appears not to be influenced by a previous conditioning irradiation. (orig.) [de

Full Text Available Eating disorders lead to special biological and psychological states. The result of the total lack of food is treated in a distinct way by anorexia. Nutritionists have thus had difficulty in coming to an agreement on the best therapy to prevent such disorders. First it is essential to understand which treatment aims are and then to attempt to know how the several treatment models used nowadays can reach those aims. Someone who suffers from eating disorders, together with an inner deformation, suffers from too much sensitiveness. In order to solve these problems, one needs a change in the relationship with oneself, with the others and with the world. This study presents a teenager’s case study – Anorexia. Is, in fact, a problem that society faces and can’t ignore. Many youngsters have already died and others are following their steps. But there are also those ones that succeeded in overcoming the problem and now are reporting their stories.

Anorexia of aging, defined as a loss of appetite and/or reduced food intake, affects a significant number of elderly people and is far more prevalent among frail individuals. Anorexia recognizes a multifactorial origin characterized by various combinations of medical, environmental and social factors. Given the interconnection between weight loss, sarcopenia and frailty, anorexia is a powerful, independent predictor of poor quality of life, morbidity and mortality in older persons. One of the most important goals in the management of older, frail people is to optimize their nutritional status. To achieve this objective it is important to identify subjects at risk of anorexia and to provide multi-stimulus interventions that ensure an adequate amount of food to limit and/or reverse weight loss and functional decline. Here, we provide a brief overview on the relevance of anorexia in the context of sarcopenia and frailty. Major pathways supposedly involved in the pathogenesis of anorexia are also illustrated. Finally, the importance of treating anorexia to achieve health benefits in frail elders is highlighted.

Purpose of review Anorexia nervosa is among the most prevalent chronic medical conditions in young adults. It has acute as well as long-term consequences, some of which, such as low bone mineral density (BMD), are not completely reversible even after weight restoration. This review discusses our current understanding of endocrine consequences of anorexia nervosa. Recent findings Anorexia nervosa is characterized by changes in multiple neuroendocrine axes including acquired hypogonadotropic hypogonadism, growth hormone resistance with low insulin-like growth factor-1 (likely mediated by fibroblast growth factor-1), relative hypercortisolemia, alterations in adipokines such as leptin, adiponectin and resistin, and gut peptides including ghrelin, PYY and amylin. These changes in turn contribute to low BMD. Studies in anorexia nervosa have demonstrated abnormalities in bone microarchitecture and strength, and an association between increased marrow fat and decreased BMD. One study in adolescents reported an improvement in BMD following physiologic estrogen replacement, and another in adults demonstrated improved BMD following risedronate administration. Brown adipose tissue is reduced in anorexia nervosa, consistent with an adaptive response to the energy deficit state. Summary Anorexia nervosa is associated with widespread physiologic adaptations to the underlying state of undernutrition. Hormonal changes in anorexia nervosa affect BMD adversely. Further investigation is underway to optimize therapeutic strategies for low BMD. PMID:24275621

Anorexia nervosa is a severe, biologically based brain disorder with significant medical complications. It is critical that new, effective treatments are developed to interrupt the persistent course of the illness due to the medical and psychological sequelae. Several psychosocial, behavioral and pharmacologic interventions have been investigated in adult anorexia nervosa; however, evidence shows that their impact is weak and treatment effects are generally small. This paper describes a new neurobiological anorexia nervosa model that shifts focus from solely external influences, such as social and family, to include internal influences that integrate genetic and neurobiological contributions, across the age span. The model serves as a theoretical structure for a new, five-day treatment, outlined in this paper, targeting anorexia nervosa temperament, which integrates neurobiological dimensions into evidence-based treatment interventions. The treatment is in two phases. Phase I is a five day, 40 hour treatment for anorexia nervosa adults. Phase II is the follow-up and is currently being developed. Preliminary qualitative acceptability data on 37 adults with anorexia nervosa and 60 supports (e.g., spouses, parents, aunts, friends, partners, children of anorexia nervosa adults) are promising from Phase I. Clients with anorexia nervosa and their supports report that learning neurobiological facts improved their understanding of the illness and helped equip them with better tools to manage anorexia nervosa traits and symptoms. In addition, nutritional knowledge changed significantly. This is the first neurobiologically based, five-day treatment for adults with anorexia nervosa and their supports. It is a new model that outlines underlying genetic and neurobiological contributions to anorexia nervosa that serves as a foundation to treat both traits and symptoms. Preliminary qualitative findings are promising, with both clients and supports reporting that the

We report a 12-year-old female citrin-deficient patient presenting with severe anorexia and body weight loss, mimicking the restricting type of anorexia nervosa (AN). She showed normal development until age 10 years when she started to play volleyball at school. She then became gradually anorexic, and her growth was stunted. At age 12, she was admitted to hospital because of severe anorexia and thinness. She was first thought to have AN, and drip infusion of glucose solution and high-calorie drinks were given, but her condition deteriorated further. She had a history of neonatal hepatitis and was therefore suspected to have citrin deficiency (CD). Genetic analysis of SLC25A13 revealed that she was compound heterozygous for 851del4 and IVS16ins3kb, and a diagnosis of CD was made. A low-carbohydrate diet with oral intake of arginine and ursodeoxycholic acid was started, and her condition gradually improved. The clinical features in our patient were similar to those of AN, and therefore AN may also be an important clinical sign in adolescent patients with CD.

El criterio diferencial que pronto aparece es el rechazo. La dificultad del sujeto con el alimento ha de situarse en el marco de la dependencia radical que tiene el organismo humano respecto al cuerpo de la madre, quebrando así la articulación entre necesidad y demanda, lo que desregula la vida instintiva. La pulsión es el nombre de esa desregulación. La vida pulsional ha de regularse por el deseo. La transmisión de la vida es transmisión del deseo íntimo de vivir. Sin él, el cuerpo desfallece o se produce una separación entre vida y cuerpo. El rechazo, que es componente de la subjetividad, pasa a convertirse en la anorexia en rechazo del cuerpo y en sumisión a ideales confusos, con los que el sujeto anoréxico pretende orientarse. La bulimia señala el aspecto más adictivo de la desregulación pulsional. La pregunta sobre por qué se da más en mujeres que en hombres no tiene fácil respuesta. A ello contribuye la sexualidad femenina (la relación con el deseo y la reproducción y también el modo como en una sociedad de la abundancia, la mujer simboliza el objeto de adorno, una figura virtual inerte. Se puede tomar la anorexia como denuncia de una vida familiar automatizada, desvitalizada, y de una sociedad caracterizada por el fetichismo de la mercancía y el canibalismo.

This study attempts to explore the cognitive processing of emotions in anorexia nervosa (AN), based on the study of emotions felt and the assessment of meta-emotional abilities. Eighty patients with AN and a control group of 80 healthy female participants were screened for anxiety, depression and alexithymia and completed an experimental task designed to analyse the emotional experience and meta-emotional abilities. Despite presenting higher levels of alexithymia, participants with AN demonstrated they were able to imagine emotions in hypothetical situations and to identify and label them. The group of patients with AN revealed feeling more intense and internally based negative emotions in comparison with the control group, but this emotional pattern tends to occur in situations associated with food and weight. Findings on meta-emotional abilities suggested no global deficit in emotional processing, but rather, specific sensitivities pertaining to situations relevant to AN.

The Information and Communication Technologies (ICT) have an increasing influence on the way we relate and in shaping personal identity. The phenomenon of online social networking emerges strongly and contributes to the development of new spaces breaking with the official discourse that marks the scientific evidence on health. This paper analyzes the impact of ICT in relation to the identity of the digital natives and eating disorders (ED). Particular attention to how the network society determines the response of young people in situations of social tension is dedicated. To do this, provides a perspective on the concept of interaction from the analysis of the discourse on anorexia and bulimia in the network, and how to care nurses should consider these factors to improve efficiency and quality in clinical care and patient care.

Full Text Available The psychoanalytic clinic for anorexia and bulimia puts us into immediate contact with the question of the body, as well as with aspects typical of adolescence. These aspects especially include difficulties in early relationships with the mother regarding the management of the drives, and relationships with primary identification. Consequently, we are dealing with ideals, differentiation, autonomy, time and death. Here hypotheses that were drawn up on the basis of metapsychology are discussed, with the objective of contributing to a broader understanding of the construction of the bodily image. This process includes the perception, representation and internal experience of the patients' own bodies. The impasses experienced in the analytic situation also indicate particularities in managing the transference in these cases.

The management of anorexia should center first on the urgent and emergent medical management of the patient and be followed by feeding of a highly palatable food in a low-stress environment and manner. Diet palatability can potentially be improved by increasing dietary moisture, fat, or protein, and, in the dog, by adding sugar or salt as well as by using a variety of fresh, pleasantly aromatic, and uncommon foods. Caution should be used when increasing or adding nutrients that may be harmful to patients with specific diseases. Concurrent drug therapy that may reduce appetite should be minimized, and physical barriers to eating should be removed. Patients that consume less than resting energy requirement of longer than 3 to 5 days with no trend toward improving should receive parenteral or enteral nutrition.

Interoceptive awareness is known to be impaired in eating disorders. To date, it has remained unclear whether this variable is related to the construct of interoceptive sensitivity. Interoceptive sensitivity is considered to be an essential variable in emotional processes. The objective of the study was to elucidate this potential relationship and to clarify whether general interoceptive sensitivity is reduced in anorexia nervosa. Using a heartbeat perception task, interoceptive sensitivity was assessed in 28 female patients with anorexia nervosa and 28 matched healthy controls. Questionnaires assessing interoceptive awareness (EDI) and several other variables were also administered. Patients with anorexia nervosa displayed significantly decreased interoceptive sensitivity. They also had more difficulties in interoceptive awareness. In addition to a decreased ability to recognize certain visceral sensations related to hunger, there is a generally reduced capacity to accurately perceive bodily signals in anorexia nervosa. This highlights the potential importance of interoceptive sensitivity in the pathogenesis of eating disorders.

Anorexia nervosa is a severe psychiatric disorder most commonly starting during the teenage-years and associated with food refusal and low body weight. Typically there is a loss of menses, intense fear of gaining weight, and an often delusional quality of altered body perception. Anorexia nervosa is also associated with a pattern of high cognitive rigidity, which may contribute to treatment resistance and relapse. The complex interplay of state and trait biological, psychological, and social factors has complicated identifying neurobiological mechanisms that contribute to the illness. The dopamine D1 and D2 neurotransmitter receptors are involved in motivational aspects of food approach, fear extinction, and cognitive flexibility. They could therefore be important targets to improve core and associated behaviors in anorexia nervosa. Treatment with dopamine antagonists has shown little benefit, and it is possible that antagonists over time increase an already hypersensitive dopamine pathway activity in anorexia nervosa. On the contrary, application of dopamine receptor agonists could reduce circuit responsiveness, facilitate fear extinction, and improve cognitive flexibility in anorexia nervosa, as they may be particularly effective during underweight and low gonadal hormone states. This article provides evidence that the dopamine receptor system could be a key factor in the pathophysiology of anorexia nervosa and dopamine agonists could be helpful in reducing core symptoms of the disorder. This review is a theoretical approach that primarily focuses on dopamine receptor function as this system has been mechanistically better described than other neurotransmitters that are altered in anorexia nervosa. However, those proposed dopamine mechanisms in anorexia nervosa also warrant further study with respect to their interaction with other neurotransmitter systems, such as serotonin pathways.

Inherent to anorexia nervosa and bulimia nervosa are a plethora of medical complications which correlate with the severity of weight loss or the frequency and mode of purging. Yet, the encouraging fact is that most of these medical complications are treatable and reversible with definitive care and cessation of the eating-disordered behaviours. Herein, these treatments are described for both the medical complications of anorexia nervosa and those which are a result of bulimia nervosa.

The present work deals with the issue of the analyst's desire in the psychoanalytical treatment of anorexia. It analyzes important elements to establish transference in these cases, as the pursuit of death and the choice of refusing food as a way of controlling the demands of the Other. It then discusses the "analist's desire" function in this clinic. Rejecting the definition of a treatment model and the structural categorization of anorexia, we can find in the cases of the girl of Angouleme ...

The question of the links between anorexia and the refusal to eat in the elderly is often the cause of major difficulties with regard to therapeutic strategies within caregiving teams. Likewise, few studies have been carried out into the diachronic links between teenage anorexia and that of the elderly. The role of the multi-disciplinary team is essential. Copyright © 2015.

Anorexia nervosa portends the highest mortality among psychiatric diseases, despite primarily being a disease of adolescents and younger adults. Although some of this mortality risk is attributable to suicide, many deaths are likely cardiovascular in etiology. Recent studies suggest that adverse myocardial structural changes occur in this condition, which could underlie the increased mortality. Given limited prevalence of severe anorexia there is a paucity of clinical and autopsy data to discern an exact cause of death. Given this background we conducted a systematic review of the medical literature to provide a contemporary summary of the pathobiologic sequelae of severe anorexia nervosa on the cardiovascular system. We sought to elucidate the impact of anorexia nervosa in four cardiovascular domains: structural, repolarization/conduction, hemodynamic, and peripheral vascular. A number of cardiac abnormalities associated with anorexia nervosa have been described in the literature, including pericardial and valvular pathology, changes in left ventricular mass and function, conduction abnormalities, bradycardia, hypotension, and dysregulation in peripheral vascular contractility. Despite the prevalent theory that malignant arrhythmias are implicated as a cause of sudden death in this disorder, data to support this causal relationship are lacking. It is reasonable to obtain routine electrocardiography and measurements of orthostatic vital signs in patients presenting with anorexia nervosa. Echocardiography is generally not indicated unless prompted by clinical signs of disease. Admission to an inpatient unit with telemetry monitoring is recommended for patients with severe sinus bradycardia or junction rhythm, marked prolongation of the corrected QT interval, or syncope. © 2015 Wiley Periodicals, Inc.

A history of anorexia nervosa has been associated with a reduced risk of developing breast cancer. We investigated survival after breast cancer among women with a prior anorexia nervosa diagnosis compared with women in a population comparison group. This register-based study included combined data from Sweden, Denmark and Finland. A total of 76 and 1462 breast cancer cases identified among 22,654 women with anorexia nervosa and 224,619 women in a population comparison group, respectively, were included in the study. Hazard ratios (HR) for overall and breast cancer-specific mortality after breast cancer diagnosis were estimated using Cox regression. Cause of death was available only for Swedish and Danish women; therefore, the analysis on breast cancer-specific mortality was restricted to these women. We observed 23 deaths after breast cancer among anorexia nervosa patients and 247 among population comparisons. The overall mortality after the breast cancer diagnosis was increased in women with a history of anorexia nervosa compared with population comparisons (HR 2.5, 95% CI 1.6-3.9) after adjustment for age, period and extent of disease. Results were similar for overall (HR 2.3, 95% CI 1.4-3.6) and breast cancer-specific mortality (HR 2.1, 95% CI 1.3-3.6) among Swedish and Danish women. We found that female breast cancer patients with a prior diagnosis of anorexia nervosa have a worse survival compared with other breast cancer patients.

Many, even healthy, older people fail to adequately regulate food intake and experience loss of weight. Aging-associated changes in the regulation of appetite and the lack of hunger have been termed as the anorexia of aging. The etiology of the anorexia of aging is multi-factorial and includes a combination of physiological changes associated with aging (decline in smell and taste, reduced central and peripheral drive to eat, delayed gastric emptying), pathological conditions (depression, dementia, somatic diseases, medications and iatrogenic interventions, oral-health status), and social factors (poverty, loneliness). However, exact mechanisms of the anorexia of aging remain to be elucidated. Many neurobiological mechanisms may be secondary to age-related changes in body composition and not associated with anorexia per se. Therefore, further studies on pathophysiological mechanisms of the anorexia of aging should employ accurate measurement of body fat and lean mass. The anorexia of aging is associated with protein-energy malnutrition, sarcopenia, frailty, functional deterioration, morbidity, and mortality. Since this symptom can lead to dramatic consequences, early identification and effective interventions are needed. One of the most important goals in the geriatric care is to optimize nutritional status of the elderly.

Anorexia nervosa is an eating disorder observed primarily in young women. The neurobiology of the disorder is unknown but recently magnetic resonance imaging showed a volume reduction of the hippocampus in anorexic patients. Dehydration-induced anorexia (DIA) is a murine model that mimics core features of this disorder, including severe weight loss due to voluntary reduction in food intake. The energy supply to the brain is mediated by astrocytes, but whether their density is compromised by anorexia is unknown. Thus, the aim of this study was to estimate GFAP+ cell density in the main regions of the hippocampus (CA1, CA2, CA3, and dentate gyrus) in the DIA model. Our results showed that GFAP+ cell density was significantly reduced (~20%) in all regions of the hippocampus, except in CA1. Interestingly, DIA significantly reduced the GFAP+ cells/nuclei ratio in CA2 (-23%) and dentate gyrus (-48%). The reduction of GFAP+ cell density was in agreement with a lower expression of GFAP protein. Additionally, anorexia increased the expression of the intermediate filaments vimentin and nestin. Accordingly, anorexia increased the number of reactive astrocytes in CA2 and dentate gyrus more than twofold. We conclude that anorexia reduces the hippocampal GFAP+ cell density and increases vimentin and nestin expression.

Anorexia and cachexia syndrome represents a complex clinical picture that occurs in the late stage of several chronic inflammatory diseases, including cancer. Unless counteracted cancer-related anorexia and cachexia syndrome affects quality of life (QL) and survival. However, to date a standard effective treatment is lacking. The aim of this review is to describe the current pharmacological approaches for anorexia and cachexia syndrome, focusing on cancer-related syndrome. The several pharmacological agents tested so far are discussed, distinguishing them in unproven drugs, effective drugs, and drugs under investigation. Moreover, a section is devoted to the promising use of nutritional supplements and nutraceuticals. The emerging role of a multitargeted combined treatment approach is exhaustively reviewed. Considering the complex clinical picture and the multifactorial pathogenesis of anorexia and cachexia syndrome, we believe that its clinical management requires a multidisciplinary and multipharmacological approach. In our opinion the anorexia and cachexia syndrome treatment should include drugs that target the following conditions: inflammatory status, oxidative stress, nutritional disorders, muscle catabolism, anemia, immunosuppression, and fatigue. The multidimensional therapies for anorexia and cachexia syndrome should ideally be introduced within a context of the "best supportive care," which includes optimal symptom management and careful psychosocial counseling.

Anorexia and anxiety cause significant mortality and disability with female biases and frequent comorbidity after puberty, but the scarcity of suitable animal models impedes understanding of their biological underpinnings. It is reported here that in adult or weanling Syrian hamsters, relative to social housing (SH), social separation (SS) induced anorexia characterized as hypophagia, weight loss, reduced adiposity, and hypermetabolism. Following anorexia, SS increased reluctance to feed, and thigmotaxis, in anxiogenic environments. Importantly, anorexia and anxiety were induced post-puberty with female biases. SS also reduced hypothalamic corticotrophin-releasing factor mRNA and serum corticosteroid levels assessed by RT-PCR and RIA, respectively. Consistent with the view that sex differences in adrenal suppression contributed to female biases in anorexia and anxiety by disinhibiting neuroimmune activity, SS elevated hypothalamic interleukin-6 and toll-like receptor 4 mRNA levels. Although corticosteroids were highest during SH, they were within the physiological range and associated with juvenile-like growth of white adipose, bone, and skeletal muscle. These results suggest that hamsters exhibit plasticity in bioenergetic and emotional phenotypes across puberty without an increase in stress responsiveness. Thus, social separation of hamsters provides a model of sex differences in anorexia and anxiety during adulthood and their pathogeneses during adolescence. Copyright © 2014 Elsevier Inc.

Full Text Available Social cognition represents the mental processes of social interaction between oneself and others. In recent years, the interest in social cognition skills has increased in cases with eating disorders. Anorexia nervosa is an eating disorder that is associated with the multiple factors in etiology. Treatment of anorexia nervosa is still controversial. The youths diagnosed with anorexia nervosa are known to be as the most difficult group in eating disorders for building therapeutic relations. Studies, mostly suggests that there are difficulties in social cognitive functions in patients with anorexia nervosa. However, there are studies that reported different results. It seems that, the majority of studies which evaluate the social cognitive functions in patients with anorexia nervosa, are carried out with the adult age group. There are limited number of studies in child and adolescent age group. The purpose of this paper was to examinate the studies of social cognitive skills in children and adolescents diagnosed with anorexia nervosa and present the general characteristics.

Anorexia, a loss of appetite for food, can be caused by various physiological and pathophysiological conditions. In this review, firstly, clinical aspects of anorexia nervosa are summarized in brief. Secondly, hypothalamic neuropeptides responsible for feeding regulation in each hypothalamic nucleus are discussed. Finally, three different types of anorexigenic animal models; dehydration-induced anorexia, cisplatin-induced anorexia and cancer anorexia-cachexia, are introduced. In conclusion, hypothalamic neuropeptides may give us novel insight to understand and find effective therapeutics strategy essential for various kinds of anorexia.

Anorexia nervosa (AN) is a psychiatric illness characterized by excessively restricted caloric intake and abnormally high levels of physical activity. A challenging illness to treat, due to the lack of understanding of the underlying neurobiology, AN has the highest mortality rate among psychiatric illnesses. To address this need, neuroscientists are using an animal model to study how neural circuits may contribute toward vulnerability to AN and may be affected by AN. Activity-based anorexia (ABA) is a bio-behavioral phenomenon described in rodents that models the key symptoms of anorexia nervosa. When rodents with free access to voluntary exercise on a running wheel experience food restriction, they become hyperactive - running more than animals with free access to food. Here, we describe the procedures by which ABA is induced in adolescent female C57BL/6 mice. On postnatal day 36 (P36), the animal is housed with access to voluntary exercise on a running wheel. After 4 days of acclimation to the running wheel, on P40, all food is removed from the cage. For the next 3 days, food is returned to the cage (allowing animals free food access) for 2 hr daily. After the fourth day of food restriction, free access to food is returned and the running wheel is removed from the cage to allow the animals to recover. Continuous multi-day analysis of running wheel activity shows that mice become hyperactive within 24 hr following the onset of food restriction. The mice run even during the limited time during which they have access to food. Additionally, the circadian pattern of wheel running becomes disrupted by the experience of food restriction. We have been able to correlate neurobiological changes with various aspects of the animals' wheel running behavior to implicate particular brain regions and neurochemical changes with resilience and vulnerability to food-restriction induced hyperactivity.

Purpose To determine indexes of skeletal integrity by using computed tomographic (CT) trabecular texture analysis of the lumbar spine in patients with anorexia nervosa and normal-weight control subjects and to determine body composition predictors of trabecular texture. Materials and Methods This cross-sectional study was approved by the institutional review board and compliant with HIPAA. Written informed consent was obtained. The study included 30 women with anorexia nervosa (mean age ± standard deviation, 26 years ± 6) and 30 normal-weight age-matched women (control group). All participants underwent low-dose single-section quantitative CT of the L4 vertebral body with use of a calibration phantom. Trabecular texture analysis was performed by using software. Skewness (asymmetry of gray-level pixel distribution), kurtosis (pointiness of pixel distribution), entropy (inhomogeneity of pixel distribution), and mean value of positive pixels (MPP) were assessed. Bone mineral density and abdominal fat and paraspinal muscle areas were quantified with quantitative CT. Women with anorexia nervosa and normal-weight control subjects were compared by using the Student t test. Linear regression analyses were performed to determine associations between trabecular texture and body composition. Results Women with anorexia nervosa had higher skewness and kurtosis, lower MPP (P anorexia nervosa. Conclusion Patients with anorexia nervosa had increased skewness and kurtosis and decreased entropy and MPP compared with normal-weight control subjects. These parameters were associated with lowest lifetime weight and duration of amenorrhea, but there were no such associations with bone mineral density. These findings suggest that trabecular texture analysis might contribute information about bone health in anorexia nervosa that is independent of that provided with bone mineral density. © RSNA, 2016.
Full Text Available Anorexia-cachexia syndrome develops during the advanced stages of various chronic diseases in which patients exhibit a decreased food intake, weight loss, and muscle tissue wasting. For these patients, this syndrome is a critical problem leading to an increased rate of morbidity and mortality. The present pharmacological therapies for treating anorexia-cachexia have limited effectiveness. The Japanese herbal medicine rikkunshito is often prescribed for the treatment of anorexia and upper gastrointestinal disorders. Thus, rikkunshito is expected to be beneficial for the treatment of patients with anorexia-cachexia syndrome. In this review, we summarize the effects of rikkunshito and its mechanisms of action on anorexia-cachexia.Persistent loss of appetite leads to a progressive depletion of body energy stores, which is frequently associated with cachexia. Consequently, regulating appetite and energy homeostasis is critically important for treating cachexia. Ghrelin is mainly secreted from the stomach, and it plays an important role in initiating feeding, controlling gastrointestinal motility, and regulating energy expenditure. Recent clinical and basic science studies have demonstrated that the critical mechanism of rikkunshito underlies endogenous ghrelin activity. Interestingly, several components of rikkunshito target multiple gastric and central sites, and regulate the secretion, receptor sensitization, and degradation of ghrelin. Rikkunshito is effective for the treatment of anorexia, body weight loss, muscle wasting, and anxiety-related behavior. Furthermore, treatment with rikkunshito was observed to prolong survival in an animal model of cachexia. The use of a potentiator of ghrelin signaling, such as rikkunshito, may represent a novel approach for the treatment of anorexia-cachexia syndrome.

Paediatric low-grade astrocytomas of the fourth ventricle are rare tumours, generally revealed by hydrocephalus. However, some patients present with a history of severe anorexia. It might be a harbinger, which if recognized, could lead to earlier diagnosis. We decided to examine our database in order to evaluate the incidence and signification of anorexia in this context. Retrospective monocentric study of cases of low-grade astrocytomas of the fourth ventricle operated between 1991 and 2012 in our paediatric neurosurgery department. We particularly observed the clinical presentation and long-term clinical, oncological and radiological evolution. Non-parametrical tests were used (Mann-Whitney, Fisher). We reviewed 34 cases, 31 pilocytic astrocytomas and 3 diffuse astrocytomas, 16 boys and 18 girls, (M/F ratio 0.89). Mean age at diagnosis was 8 years old. Seven presented with notable anorexia, the average BMI in this group was ≤2 standard deviation (SD); with clinical signs evolving for 11.5 months. Twenty-seven children had no anorexia; average BMI in this group was +1 SD, with clinical evolution for 6 months on an average of p anorexia, body mass index improved markedly in the postoperative follow-up, which lasted, on average, for 6 years. Anorexia with stunted body weight curve is a non-exceptional presentation in children with low-grade astrocytomas of the fourth ventricle. Unexplained or atypical anorexia with negative etiologic assessment should prompt cerebral imaging. Clinical improvement after surgical resection, could suggest a possible interaction between tumour tissue and appetite-suppressing peptide secretion.

The diagnostic value of selective anorexia is debated. Some authors have suggested an association between meat aversion and cancer, but most do not use it as a diagnostic tool. We aimed to characterize anorexia of different diseases to search for an association between selective aversions and diagnostic groups. All the patients admitted to three departments of a teaching hospital were included consecutively for 22months if they had more than 10 % weight loss in less than one year. Patients were excluded if history taking was not reliable, or if they suffered from anorexia nervosa. We compiled diagnoses at discharge and validated them six months later. We used logistic regression to identify independent factors associated with selective anorexia. Inclusion criteria were met in 106patients (female 44 %, median age 65years). Most frequent diagnoses were: cancer (36 %), infection (35 %), digestive diseases (19 %), non organic diseases (21 %). Recent selective anorexia was found in 46 % of the cases. It was significantly associated with female gender (P=0.002), marginally with young age (P=0.069) and long duration of weight loss (P=0.079). Opioid use at admission was negatively associated with selective anorexia (P=0.001). No specific diagnostic category was found to be associated. Selective anorexia does not appear to be a useful symptom to investigate pathological weight loss. It behaves more like a non-specific reactivation by current disease of earlier latent personal food aversions. Copyright © 2015 Société nationale française de médecine interne (SNFMI).

Full Text Available Anorexia Nervosa (AN has a mortality rate among the highest of any mental illness, though the factors involved in the condition remain unclear. Recently, the potential neurobiological underpinnings of the condition have become of increasing interest. Saccadic eye movement tasks have proven useful in our understanding of the neurobiology of some other psychiatric illnesses as they utilise known brain regions, but to date have not been examined in AN. The aim of this study was to investigate whether individuals with AN differ from healthy individuals in performance on a range of saccadic eye movements tasks.24 females with AN and 25 healthy individuals matched for age, gender and premorbid intelligence participated in the study. Participants were required to undergo memory-guided and self-paced saccade tasks, and an interleaved prosaccade/antisaccade/no-go saccade task while undergoing functional magnetic resonance imaging (fMRI.AN participants were found to make prosaccades of significantly shorter latency than healthy controls. AN participants also made an increased number of inhibitory errors on the memory-guided saccade task. Groups did not significantly differ in antisaccade, no-go saccade or self-paced saccade performance, or fMRI findings.The results suggest a potential role of GABA in the superior colliculus in the psychopathology of AN.

A growing body of evidence suggests that our diet is an important contributing factor in the development, management and prevention of a number of psychiatric illnesses. Tryptophan, an essential amino acid, is the sole precursor of neurotransmitter 5-hydroxytryptamine (5-HT; serotonin). Administration of tryptophan can boost serotonin neurotransmission to produce therapeutically important effects in serotonin deficiency disorders. Anorexia nervosa (AN) an eating disorder associated with high levels of psychiatric comorbidity including psychosis, hyperactivity, depression and anxiety has highest lethality of all psychiatric illnesses. Evidence suggests that excessive dieting and food restriction can decrease brain tryptophan and serotonin in AN patients to precipitate depression, psychosis and hyperactivity. There are currently no FDA approved pharmacological treatments available for AN patients; antidepressants and antipsychotics, largely used to treat associated psychiatric comorbidities are also not very effective. The aim of this non-systematic review article is to evaluate and document a potential importance of tryptophan supplementation in improving therapeutics in AN patients. Copyright © 2017 Elsevier Inc.

Objective Recent research has identified specific cognitive deficits in patients with anorexia nervosa (AN), including impairment in executive functioning and attention. Another such cognitive process, implicit category learning has been less studied in AN. This study examined whether implicit category learning is impaired in AN. Method Twenty-one women diagnosed with AN and 19 control women (CW) were administered an implicit category learning task in which they were asked to categorize simple perceptual stimuli (Gabor patches) into one of two categories. Category membership was based on a linear integration (i.e., an implicit task) of two stimulus dimensions (orientation and spatial frequency of the stimulus). Results AN individuals were less accurate on implicit category learning relative to age-matched CW. Model-based analyses indicated that, even when AN individuals used the appropriate (i.e., implicit) strategy they were still impaired relative to CW who also used the same strategy. In addition, task performance in AN patients was worse the higher they were in self-reported novelty seeking and the lower they were in sensitivity to punishment. Conclusions These results indicate that AN patients have implicit category learning deficits, and given this type of learning is thought to be mediated by striatal dopamine pathways, AN patients may have deficits in these neural systems. The finding of significant correlations with novelty seeking and sensitivity to punishment suggests that feedback sensitivity is related to implicit learning in AN. PMID:22201300

The present study sought to investigate emotion regulation strategies in people with anorexia nervosa (AN) and whether the theoretical concept of 'emotion coupling' between anger and disgust could help to explain some of the specific eating disorder symptomatology in people with AN. This 'emotion coupling' hypothesis was tested using a mood induction procedure within laboratory conditions, where individuals with AN (n = 22) were matched with control participants (n = 19). Participants completed a bank of different measures prior to the study, and these included measures of eating pathology, core beliefs about the self and others, and emotion regulation strategies. Within the experimental part of this study, anger, disgust and body size estimation were measured prior to and after an anger induction procedure (i.e., a repeated measures design). People with AN demonstrated a significantly more internal-dysfunctional way to regulate their emotional states, when compared with matched controls. Within the 'emotional coupling' part of the study, participants showed a significant increase in levels of disgust and body size estimation following an anger induction when compared with matched controls. The significance of these results was considered in the light of the new Schematic, Propositional, Analogical and Associative Representation Systems in eating disorders model.

Anorexia nervosa is a frequent disorder especially among adolescent girls and young women, with high morbidity, mortality, and relapse rates. To date, no single therapeutic approach has proved to be superior to others (Herpertz et al., 2011). It remains unclear how its etiology and pathology are encoded within cognitive, neural, and endocrinological processes that modulate important mechanisms in appetitive processing and weight regulation. Yet, several trait characteristics have been identified in AN which might reflect predisposing factors. Further, altered levels of neuropeptides and hormones that regulate appetite and feeding behavior have been found during both the acute and the recovered state, pointing to dysfunctional mechanisms in AN that persist even after malnutrition has ceased. Researchers are also hoping that brain imaging techniques will allow for a more detailed investigation of the neural basis of reward and punishment sensitivity that appears to be altered in AN. The integration and extension of recent findings in these areas will hopefully provide a more comprehensive understanding of the disorder and hence enable the development of more effective treatments.

Previous studies of prognostic factors of anorexia nervosa (AN) course and recovery have followed clinical populations after treatment discharge. This retrospective study examined the association between prognostic factors—eating disorder features, personality traits, and psychiatric comorbidity—and likelihood of recovery in a large sample of women with AN participating in a multi-site genetic study. The study included 680 women with AN. Recovery was defined as the offset of AN symptoms if the participant experienced at least one year without any eating disorder symptoms of low weight, dieting, binge eating, and inappropriate compensatory behaviors. Participants completed a structured interview about eating disorders features, psychiatric comorbidity, and self-report measures of personality. Survival analysis was applied to model time to recovery from AN. Cox regression models were used to fit associations between predictors and the probability of recovery. In the final model, likelihood of recovery was significantly predicted by the following prognostic factors: vomiting, impulsivity, and trait anxiety. Self-induced vomiting and greater trait anxiety were negative prognostic factors and predicted lower likelihood of recovery. Greater impulsivity was a positive prognostic factor and predicted greater likelihood of recovery. There was a significant interaction between impulsivity and time; the association between impulsivity and likelihood of recovery decreased as duration of AN increased. The anxiolytic function of some AN behaviors may impede recovery for individuals with greater trait anxiety. PMID:23535032

Disturbance of body perception is a central aspect of anorexia nervosa (AN) and several neuroimaging studies have documented structural and functional alterations of occipito-temporal cortices involved in visual body processing. However, it is unclear whether these perceptual deficits involve more basic aspects of others' body perception. A consecutive sample of 15 adolescent patients with AN were compared with a group of 15 age- and gender-matched controls in delayed matching to sample tasks requiring the visual discrimination of the form or of the action of others' body. Patients showed better visual discrimination performance than controls in detail-based processing of body forms but not of body actions, which positively correlated with their increased tendency to convert a signal of punishment into a signal of reinforcement (higher persistence scores). The paradoxical advantage of patients with AN in detail-based body processing may be associated to their tendency to routinely explore body parts as a consequence of their obsessive worries about body appearance.

Full Text Available The compulsive nature of weight loss behaviours central to Anorexia Nervosa (AN, such as relentless self-starvation and over-exercise, has led to the suggestion of parallels between AN and other compulsive disorders such as Obsessive-Compulsive Disorder (OCD and addictions. There is a huge unmet need for effective treatments in AN, which has high rates of morbidity and the highest mortality rate of any psychiatric disorder, yet a grave paucity of effective treatments. Viewing compulsivity as a transdiagnostic concept, seen in various manifestations across disorders, may help delineate the mechanisms responsible for the persistence of AN, and aid treatment development. We explore models of compulsivity that suggest dysfunction in cortico-striatal circuitry underpins compulsive behaviour, and consider evidence of aberrances in this circuitry across disorders. Excessive habit formation is considered as a mechanism by which initially rewarding weight loss behaviour in AN may become compulsive over time, and the complex balance between positive and negative reinforcement in this process is considered. The physiological effects of starvation in promoting compulsivity, positive reinforcement and habit formation are also discussed. Further research in AN may benefit from a focus on processes potentially underlying the development of compulsivity, such as aberrant reward processing and habit formation. We discuss the implications of a transdiagnostic perspective on compulsivity, and how it may contribute to the development of novel treatments for AN.

The disturbances related to the feeding behavior are increasing in Tunisia. To evaluate the impact of an adapted and personalized therapeutic program, including dietetic advises and practice of yoga in Tunisian teenagers suffering from bulimia or anorexia. Our study was carried out on 31 teenagers, old 16 to 19 years, 10 were anorexics (9 girls and 1 boy) and 21 were bulimics (14 girls and 7 boys). After twelve weeks of program application a clear improvement of the physical and mental state of our subjects was recorded. Indeed, an average fall of 7.3% of the body weight of the compulsive eaters and an increase of 6.6% of that of the anorexics were obtained. On the mental level, the frequency of the subjects which make daily crises passed from 29% to 19%. More half of the subjects (54.8%) paid more not to vomit but occasionally (less than one once out of two crises). These results show that an assumption of responsibility targeted of the teenagers suffering from food behavioral problems can help them to be left there.

Women with anorexia nervosa have reduced skeletal mass. Both anorexia and osteopenia are less common in men. We describe a 22-year-old man with anorexia nervosa and severe osteopenia involving both cortical and trabecular bone who developed a pelvic fracture and multiple vertebral compression fractures. He was found to have secondary hypogonadotropic hypogonadism that was reversible with weight gain. This case illustrates the need to consider osteopenia as a potential complication of anorexia nervosa in males as well as females

To compare body composition patterns before and after complete weight restoration in men with anorexia nervosa. Dual-energy X-ray absorptiometry (DXA) was used to measure body composition patterns in 10 men with anorexia nervosa before and after complete weight restoration, and in 10 healthy men matched to age and patients' post-treatment body mass index (BMI). Before weight restoration, men with anorexia nervosa displayed lower total body fat mass (FM) and lean mass (LBM) than those in the healthy comparison group, with a greater FM loss from the extremity than the trunk region. After short-term weight restoration, patients displayed complete normalization in total LBM and FM, but greater deposition of FM in the trunk region. Short-term weight restoration can normalize body composition patterns in men with anorexia nervosa, but results in a central adiposity phenotype. The clinical implication of this finding is unknown, but should be explored given the high levels of concern about central adiposity in anorexia nervosa. © 2017 Wiley Periodicals, Inc.

In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with chronic uncomplicated semistarvation, TBK and TBW were measured by whole body K40 counting and deuterium oxide dilution in 10 females with stable anorexia nervosa and 10 age-matched female controls. The ratio of TBK/TBW was significantly (p less than 0.05) higher in anorexia nervosa patients than controls. The close inverse correlation found in published studies between TBK/TBW and Nae/Ke together with our results suggest that in anorexia nervosa, Nae/Ke may be low or normal. A decreased TBK/TBW is not a good indicator of malnutrition in the anorexia nervosa patient. The use of a decreased TBK/TBW ratio or an elevated Nae/Ke ratio as a definition of malnutrition may result in inappropriate nutritional management in the patient with severe nonstressed chronic semistarvation.

Full Text Available In Anorexia Nervosa the observable phenomenon is the suppression of appetite. Little is known about the biological and psychological (top-down bases that maintain this pathological state. However, Anorexia Nervosa is a biological, psychological and social model where the main behavioral characteristic is the inhibition of eating behavior; not by bottom-up but top-down regulation. Objective: To explore the areas of the brain associated with food appetency through functional magnetic resonance in women with anorexia nervosa. Methods: The subjects include 5 female with Restrictive type of Anorexia Nervosa and five controls female with similar in age and low weigh. The subjects were within the MRI scanner and while took fMRI they saw food images that would generate appetite. The subjects were in fasting state and mentally prepare by instruction “imagine you are eating the food presented in the following images”. Results: Compared differences in the activation between subjects four regions were found significant: the anterior cingulate, left front medial region and the left and right midbrain. Conclusions: The patients with Anorexia Nervosa present different activated cerebral areas to those of the controls during the visual exposition to food in hungry state and with evoke cognitions associated with eat food; those regions may be implicated in reward and self-control.

Full Text Available Abstract We report two patients with anorexia nervosa and Graves' disease who received subtotal thyroidectomy for Graves' disease and concomitantly experienced remission from anorexia nervosa. Both were young women (aged 20 and 26 at the time of surgery. Both had well controlled thyroid function and eating behavior at the time of surgery. Both were followed for over five years without relapse of anorexia nervosa or hyperthyroidism. These cases suggest the existence of an endocrine factor originating from the thyroid gland that is involved in the pathogenesis of anorexia nervosa. Since patients of thyroidectomy can remain in good health with supplement of thyroxine alone, it can be hypothesized that this anorexigenic endocrine factor is an evolutionary relic not necessary for the normal function of humans and does not have physiological effects unless secreted beyond normal levels. Given that, it implies the existence of a creature in the animal kingdom for which such an anorexigenic hormone is essential for survival. Migrating birds eat beyond their caloric expenditure before migration and become anorexic for the duration of their flight. It is also known that their thyroid function is elevated during migration. The normal physiology of migration is a complex mechanism involving the hypothalamic, pituitary, thyroid, adrenal and reproductive hormones. The mechanism of disease, however, can be simpler. A review of the literature is presented that suggest a heretofore unreported thyroid hormone, which is involved in the regulation of migration behavior, may be the responsible factor behind anorexia nervosa.

In 20 female patients with anorexia nervosa, aging 16 - 26 years, the thyroid function was estimated by +- determining TSH secretion in response to TRH, and serum thyroxine (T 4 ), 3,5,3'L-triiodothyronine (T 3 ) and 3,3',5'L-triiodothyronine (reverse T 3 ) concentrations. 14 healthy women of the same age were included into the control group. If compared with control group, a marked supression of TRH stimulated TSH secretion and a lowering of serum T 3 concentration was found in patients with anorexia nervosa. On the other hand, serum reverse T 3 concentration was markedly higher in patients with anorexia nervosa than in control ones. Gain of body weight leads to normalization of thyroid hormones level in the serum. Obtained results show for peripheral mechanism of described hormonal disorders. (author)
Full Text Available The role of Defensive exclusion (Deactivation and Segregated Systems in the development of early relationships and related to subsequent manifestations of symptoms of eating disorders was assessed using the Adult Attachment Projective Picture System (AAP. Fifty-one DSM-IV diagnosed women with anorexia participated in the study. Anorexic patients were primarily classified as dismissing or unresolved. Quantitative and qualitative analyses of defensive exclusion were carried out. Results showed potential benefits of using the AAP defense exclusion coding system, in addition to the main attachment classifications, in order to better understand the developmental issues involved in anorexia. Discussion concerned the processes, such as pathological mourning, that may underlie the associations between dismissing and unresolved attachment and anorexia. Implications for developmental research and clinical nosology are discussed.

Hyperactivity in anorexia nervosa is difficult to control and negatively impacts outcome. Hyperactivity is a key driving force to starvation in an animal model named activity-based anorexia (ABA). Recent research has started unraveling what mechanisms underlie this hyperactivity. Besides a general increase in locomotor activity that may be an expression of foraging behavior and involves frontal brain regions, the increased locomotor activity expressed before food is presented (food anticipatory behavior or FAA) involves hypothalamic neural circuits. Ghrelin plays a role in FAA, whereas decreased leptin signaling is involved in both aspects of increased locomotor activity. We hypothesize that increased ghrelin and decreased leptin signaling drive the activity of dopamine neurons in the ventral tegmental area. In anorexia nervosa patients, this altered activity of the dopamine system may be involved not only in hyperactivity but also in aberrant cognitive processing related to food.

To discuss the application of the principles of participatory action research (PAR) in a project that developed and evaluated a mentor-mentee support programme for women with anorexia nervosa. A programme was developed and implemented in which mentors and mentees participated in workshops, social activities and focus groups that sought to support and develop resilience for those experiencing anorexia nervosa. PAR principles were mirrored in the programme, paying respect to the views and needs of each participant, an open trajectory to possible conclusions and a continuous feedback cycle. Mentees had a sense of empowerment, ownership of the programme and hope that recovery was possible. It allowed their voices to be heard and provided them with belief they could begin new relationships and friendships. The principles of PAR suited a project aimed at developing self-determination and resilience in women with anorexia nervosa. PAR would be readily transferable to a number of mental health settings where empowerment is of paramount concern.

Studies concerning eating disorder patients have revealed the presence of alexithymia, depressive, and anxiety disorders. We compared these aspects of emotional functioning in two groups of anorexia nervosa (AN) patients: adolescents vs. adults. Forty-eight adolescent anorexia nervosa patients (ADO) and 23 adult anorexia nervosa patients (ADU) completed a battery of tasks and questionnaires to measure these different aspects of emotional functioning and to control for differences of a more general cognitive nature. Both groups showed marked resemblance; both had high alexithymia scores and performed worse on emotional tasks measuring aspects of alexithymia. Furthermore, both groups showed high percentages of depressive and anxiety disorders, with the ADU group scoring only higher on specific and social phobia than the ADO group.

Anorexia nervosa is a serious psychiatric illness with limited evidenced-based treatment options. Mindfulness appears useful in many conditions, but few studies focus on its use in individuals with anorexia nervosa. To examine and summarize studies of mindfulness in individuals with anorexia nervosa and identify areas for future research. An integrated review was conducted by searching health care computerized databases. Results were mixed among the eight studies that met inclusion criteria. Multimodal mindfulness-based therapies appear effective, while brief interventions may be equally useful or result in greater anxiety compared to distraction. Qualitative data support that some participants feel mindfulness is challenging but beneficial. Mindfulness as a concurrent part of therapy and/or when routinely practiced may be more clinically useful than single-episode mindful eating interventions. Due to the complexity of the concept of mindfulness and limited existing data, additional research is needed.

Decision-making (DM) abilities have been found to be impaired in anorexia nervosa (AN), but few data are available about the characteristics and correlates of this cognitive function. The aim of the present study was to provide data on DM functioning in AN using both veridical and adaptive paradigms. While in veridical DM tasks, the individual's ability to predict a true/false response is measured, adaptive DM is the ability to consider both internal and external demands in order to make a good choice, in the absence of a single true "correct" answer. The participants were 189 women, of whom 91 were eating-disordered patients with a lifetime diagnosis of anorexia nervosa, and 98 were healthy women. All the participants underwent clinical, neuropsychological, and genetic assessment. The cognitive evaluation included a set of neuropsychological tasks and two decision-making tests: The Iowa Gambling Task and the Cognitive Bias Task. Anorexia nervosa patients showed significantly poorer performances on both decision-making tasks than healthy women. The Cognitive Bias Task revealed that anorexia nervosa patients employed significantly more context-independent decision-making strategies, which were independent from diagnostic subtype, handedness, education, and psychopathology. In the whole sample (patients and controls), Cognitive Bias Task performance was independently predicted by lifetime anorexia nervosa diagnosis, body mass index at assessment, and 5-HTTLPR genotype. Patients displayed poor decision-making functioning in both veridical and adaptive situations. The difficulties detected in anorexia nervosa individuals may affect not only the ability to consider the future outcomes of their actions (leading to "myopia for the future"), but also the capacity to update and review one's own mindset according to new environmental stimuli.

Anorexia (AN) and Bulimia Nervosa (BN) are two common eating disorders, which appear to share some reduced motor capacities, such as a reduced balance. The presence and the extent of other motor disorders have not been investigated in a comprehensive way. The aim of this study was to quantify gait pattern in AN and BN individuals in order to ascertain possible differences from the normality range and provide novel data for developing some evidence-based rehabilitation strategies. Nineteen AN patients (age 30.16+9.73) and 20 BN patients (age 26.8+8.41) were assessed with quantitative 3D computerized Gait Analysis. Results were compared with a group of healthy controls (CG; 30.7+5.6). AN and BN patients were characterized by different gait strategies compared to CG. Spatio-temporal parameters indicated shorter step length, with AN showing the shortest values. AN walked slower than BN and CG. As for kinematics, AN and BN showed a nonphysiologic pattern at pelvis and hip level on the sagittal and frontal plane, with BN yielding the most abnormal values. Both AN and BN patients were characterized by high ankle plantar flexion capacity at toe-off when compared to CG. As for ankle kinetics, both AN and BN showed physiologic patterns. Stiffness at hip level was close to CG in both pathologic groups; at the ankle level, stiffness was significantly decreased in both groups, with AN displaying lower values. Both AN and BN were characterized by an altered gait pattern compared to CG. Biomechanical differences were evident mainly at pelvis and hip level. Loss of lean mass may lead to musculoskeletal adaptation, ultimately causing alterations in the gait pattern.
Background: The etiology of Anorexia Nervosa (AN) is unknown.

Anorexia is the most frequent modification of eating habits in old age, which may lead to malnutrition and consequent morbidity and mortality in older adults. We aimed to estimate the prevalence and factors associated to anorexia in a sample of Italian older persons living in different settings. Our secondary aim was to evaluate the impact of senile anorexia on nutritional status and on eating habits, as well as on functional status. Observational study in nursing homes, in rehabilitation and acute geriatric wards, and in the community in four Italian regions (Lazio, Sicily, Emilia-Romagna, and Veneto). 526 over 65 years old participants were recruited; 218 free-living subjects, 213 from nursing homes, and 96 patients from rehabilitation and acute geriatric wards in the context of a National Research Project (PRIN) from the Italian Ministry of Instruction, University and Research (2005-067913 "Cause e Prevalenza dell'Anoressia senile"). Anthropometric and nutritional evaluation, olfactory, chewing, and swallowing capacity, food preferences, cognitive function, functional status, depression, quality of life, social aspects, prescribed drugs, and evaluation of gastrointestinal symptoms and pain. Laboratory parameters included prealbumin, albumin, transferrin, C-reactive protein, mucoprotein, lymphocyte count, as well as neurotransmitters leptin, and ghrelin. Anorexia was considered as ≥50% reduction in food intake vs. a standard meal (using 3-day "Club Francophone de Gériatrie et Nutrition" form), in absence of oral disorders preventing mastication. The overall prevalence of anorexia was 21.2% with higher values among hospitalized patients (34.1% women and 27.2% men in long-term facilities; 33.3% women and 26.7% men in rehabilitation and geriatric wards; 3.3% women and 11.3% men living in the community) and in the oldest persons. Anorexic subjects were significantly less self-sufficient and presented more often a compromised nutritional and cognitive status. Diet

A anorexia tem-se despontado como um dos grandes sintomas da atualidade. Especialmente entre jovens, a recusa radical da alimentação, associada a uma busca por um ideal de corpo esbelto, pode levar a situações extremas de emagrecimento, chegando, em alguns casos, a causar a própria morte. O aumento da incidência de anorexia fez com que as ciências da saúde e os serviços públicos a tomassem como uma de suas grandes preocupações. Diversas pesquisas surgiram, tentando compreender melhor a anorex...
German-language publications on anorexia nervosa and Simmonds' disease from between 1900 and 1945 are reviewed in order to trace factors inherent in medical thinking which have mostly hindered German-language medicine in understanding anorexia nervosa. It is demonstrated that a) the few German-language physicians who did describe central and possible characteristics of a.n. (weight-phobia, overactivity, bulimia, self-induced vomiting) were enabled to do so by valuing detailed clinical description, also of psychic characteristics, and an interest in the neuroses; b) the concept of anorexia nervosa was better known than previously assumed, though largely misunderstood; c) typical diagnostic misinterpretations led to typical biases in the description of the syndrome; d) in Germany more than in other countries a.n. was confounded with Simmonds' disease; and e) in addition to other factors, one reason for this lay in the 'holistic' ideal of psychosomatic medicine in the 1930s.

Many social psychological models propose that positive self-conceptions promote self-esteem. An extreme version of this hypothesis is advanced in "pro-anorexia" communities: identifying with anorexia, in conjunction with disordered eating, can lead to higher self-esteem. The current study empirically tested this hypothesis. Results challenge the pro-anorexia hypothesis. Although those with higher levels of pro-anorexia identification trended towards higher self-esteem with increased disordered eating, this did not overcome the strong negative main effect of pro-anorexia identification. These data suggest a more effective strategy for promoting self-esteem is to encourage rejection of disordered eating and an anorexic identity.

Anorexia nervosa is a psychiatric illness characterized by low weight, disordered eating, and hallmark neuroendocrine dysfunction. Behavioral phenotypes are defined by predominant restriction or bingeing/purging; binge-eating/purging type anorexia nervosa is associated with poorer outcome. The pathophysiology underlying anorexia nervosa types is unknown, but altered hormones, known to be involved in eating behaviors, may play a role. To examine the role of anorexigenic hormones in anorexia nervosa subtypes, we examined serum levels of peptide YY (PYY; total and active [3-36] forms), brain-derived neurotrophic factor (BDNF), and leptin as primary outcomes in women with DSM-5 restricting type anorexia nervosa (n = 50), binge-eating/purging type anorexia nervosa (n = 25), and healthy controls (n = 22). In addition, women completed validated secondary outcome measures of eating disorder psychopathology (Eating Disorder Examination-Questionnaire) and depression and anxiety symptoms (Hamilton Rating Scales for Depression [HDRS] and Anxiety [HARS]). The study samples were collected from May 22, 2004, to February 7, 2012. Mean PYY 3-36 and leptin levels were lower and BDNF levels higher in binge-eating/purging type anorexia nervosa than in restricting type anorexia nervosa (all P values anorexia nervosa types were significant (P anorexia nervosa, the anorexigenic hormones PYY, BDNF, and leptin are differentially regulated between the restricting and binge/purge types. Whether these hormone pathways play etiologic roles with regard to anorexia nervosa behavioral types or are compensatory merits further study. © Copyright 2015 Physicians Postgraduate Press, Inc.

Purpose To investigate the composition, cross-sectional area (CSA), and hormonal correlates of different fat depots in women with anorexia nervosa (AN) and control subjects with normal weights to find out whether patients with AN have lower fat CSA but higher attenuation than did control subjects and whether these changes may be mediated by gonadal steroids, cortisol, and thyroid hormones. Materials and Methods This study was institutional review board approved and HIPAA compliant. Written informed consent was obtained. Forty premenopausal women with AN and 40 normal-weight women of comparable age (mean age ± standard deviation, 26 years ± 5) were studied. All individuals underwent computed tomography of the abdomen and thigh with a calibration phantom. Abdominal subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), thigh SAT, and thigh intermuscular adipose tissue CSA and attenuation were quantified. Serum estradiol, thyroid hormones, and urinary free cortisol levels were assessed. Variables were compared by using analysis of variance. Associations were examined by using linear regression analysis. Results Women with AN had higher fat attenuation than did control subjects (−100.1 to −46.7 HU vs −117.6 to −61.8 HU, P < .0001), despite lower fat CSA (2.0–62.8 cm2 vs 5.5–185.9 cm2, P < .0001). VAT attenuation but not CSA was inversely associated with lowest prior lifetime body mass index in AN (r = −0.71, P = .006). Serum estradiol levels were inversely associated with fat attenuation (r = −0.34 to −0.61, P = .03 to <.0001) and were positively associated with fat CSA of all compartments (r = 0.42–0.64, P = .007 to <.0001). Thyroxine levels and urinary free cortisol levels were positively associated with thigh SAT attenuation (r = 0.64 [P = .006] and r = 0.68 [P = .0004], respectively) and were inversely associated with abdominal SAT and VAT CSA (r = −0.44 to −0.58, P = .04 to .02). Conclusion Women with AN have differences in fat
Full Text Available The aim of this study is to investigate the bodily-self in Restrictive Anorexia, focusing on two basic aspects related to the bodily self: autonomic strategies in social behavior, in which others' social desirability features, and social cues (e.g., gaze are modulated, and interoception (i.e., the sensitivity to stimuli originating inside the body. Furthermore, since previous studies carried out on healthy individuals found that interoception seems to contribute to the autonomic regulation of social behavior, as measured by Respiratory Sinus Arrhythmia (RSA, we aimed to explore this link in anorexia patients, whose ability to perceive their bodily signal seems to be impaired. To this purpose, we compared a group of anorexia patients (ANg; restrictive type with a group of Healthy Controls (HCg for RSA responses during both a resting state and a social proxemics task, for their explicit judgments of comfort in social distances during a behavioral proxemics task, and for their Interoceptive Accuracy (IA. The results showed that ANg displayed significantly lower social disposition and a flattened autonomic reactivity during the proxemics task, irrespective of the presence of others' socially desirable features or social cues. Moreover, unlike HCg, the autonomic arousal of ANg did not guide behavioral judgments of social distances. Finally, IA was strictly related to social disposition in both groups, but with opposite trends in ANg. We conclude that autonomic imbalance and its altered relationship with interoception might have a crucial role in anorexia disturbances.

The purpose of this article is to review the basic pharmacology and the role of drugs that are used to treat anorexia nervosa and bulimia. The pharmacological treatment of eating disorders is based upon theoretical principles. The theoretical models include: (a) an illness secondary to other psychiatric disorders, (b) a disorder in the hypothalamic control of food intake, (c) a disorder of hypothalamic endocrine regulation, (d) a syndrome secondary to depressive illness, and (e) a disorder in the hypothalamic regulation of food intake. Theoretical models a, b, and c govern the choice of drug therapy for anorexia nervosa, and models d and e govern the choice of drug therapy for bulimia. Drugs used to treat anorexia nervosa and bulimia include tricyclic antidepressants and lithium carbonate. Chlorpromazine, metoclopramide, cyproheptadine, and clomiphene citrate have also been prescribed for the treatment of anorexia nervosa. Monoamine oxidase inhibitors are commonly prescribed to treat bulimia. Fenfluramine has the potential to be of therapeutic value in patients with bulimia. Although drug therapy plays a limited role in the treatment of eating disorders, drugs are commonly prescribed. Therefore, the nutritionist should be familiar with the basic pharmacology and the side effects related to drug therapy.

In a two-center follow-up study on the early-onset form of anorexia nervosa, we reexamined 43 (74%) of 58 former patients who had developed anorexia nervosa at the age of 13 years or younger. In addition to make a standardized assessment of the eating disorder at follow-up we assessed psychiatric comorbidity with a structured interview based on the criteria of DSM-III-R and ICD-10. After an average follow-up period of 6.8 years, 8 (18%) of our former patients had an eating disorder not otherwise specified (EDNOS) and 4 (9%) still suffered from anorexia nervosa. 5 (11%) of the subjects had developed bulimia nervosa. In 3 cases (7%) we found both syndromes. 12 (28%) of our former patients had an additional psychiatric disorder. The results of our study indicate that the quality of outcome in patients with an early-onset form of anorexia nervosa does not differ from that in individuals with a later manifestation of the eating disorder. Factors of prognostic relevance were the existence of an eating disorder during the first year of life and the duration of the follow-up period.

The course of anorexia nervosa frequently has episodes of exacerbation during which motivation and insight are reduced, cognition is impaired and treatment resistance is increased. Formalizing a directive to be used during these episodes when the patient has greater motivation and insight is one way of reducing treatment resistance. We describe a form of directive, called the "Ulysses Agreement".

Anorexia nervosa has been related to alterations in brain activity in terms of hyperactive EEG patterns. This case report illustrates the principles and results of a five-week neurofeedback treatment in a 29-year-old woman suffering from anorexia nervosa. A neurofeedback protocol to enhance alpha activity (8 - 12 Hz) was developed and conducted additionally to the standardized treatment for eating disorders in training sessions twice a week. Pre- and post-test measurements included resting state EEG measurements and a psychological test battery. The results show improvements from pre- to post-test in eating disorder psychopathology including psychological wellbeing, emotional competence, and eating behavior traits. In addition, a decrease in theta power (4 - 7 Hz), a well-known trait marker of anorexia nervosa, was measured. However, our data should be interpreted with caution because this is a single case study. Nevertheless, this report documents the practicability and method of neurofeedback as treatment adjunct in eating disorders from the clinical perspective. Although the use of neurofeedback in the treatment of anorexia nervosa is recommended in literature, empirical studies are still lacking. Randomized controlled trials to evaluate short- and long-term effects of neurofeedback are needed. © Georg Thieme Verlag KG Stuttgart · New York.

The purpose of this review is to examine the concept of anorexia of aging, including its complex pathophysiology and the multifaceted interventions required to prevent adverse health consequences from this geriatric syndrome. Anorexia of aging is extremely common, occurring in up to 30% of elderly individuals; however, this diagnosis is frequently missed or erroneously attributed to a normal part of the aging process. With aging, impairments in smell and taste can limit the desire to eat. Alterations in stress hormones and inflammatory mediators can lead to excess catabolism, cachexia, and reduced appetite. In addition, mood disorders, such as anxiety and depression, are powerful inhibitors of appetite. Anorexia of aging, with its negative consequences on weight and muscle mass, is a risk factor for the development of frailty and is important to screen for, as early intervention is key to reversing this debilitating condition. Anorexia of aging is a complex geriatric syndrome and a direct risk factor for frailty and thus should not be accepted as normal consequence of aging. Early diagnosis and formulating a plan for targeted interventions is critical to prevent disability and preserve function in elderly patients.

During the last decades, there has been a rising interest in the role of shame in psychiatric disorders. To define shame and describe types and subtypes of shame and their relations to symptoms and meaning in anorexia nervosa. The study will also describe the possible role of pride, as a contrasting emotional and cognitive experience. Thirteen female patients (age 16-39 years) with anorexia nervosa were interviewed about their general understanding of the concept of shame, what they considered shameful in themselves, past and present, and in others and shame related to eating and body. Based on statements from the patients 'globalised internal shame', different subtypes of focal shame and different subtypes of pride are categorised. Shame is described both as cause and consequence in relation to symptoms in anorexia nervosa, hence a shame-shame cycle. A shame-pride cycle is also presented. The use of shame, as well as pride, as concepts in regard to anorexia nervosa may improve our understanding of the nature of this disorder, as well as being a guideline for therapists. 2007 John Wiley & Sons, Ltd and Eating Disorders Association

The most common pathological change in eating behaviour among older persons is anorexia, which accounts for a large percent of undernutrition in older adults. The main research aims are to determine, in a sample of acute and rehabilitation elderly subjects, the prevalence of anorexia of aging and the causes most impacting on senile anorexia. four different Units cooperated to this research study. Patients were recruited from geriatric acute and rehabilitation wards in Italy. Each Research Unit, for the estimation of the prevalence of anorexia in elderly subjects evaluated all the patients aged over 65 recruited from April 2006 to June 2007. Nutritional status, depression, social, functional and cognitive status, quality of life, health status, chewing, swallowing, sensorial functions were evaluated in anorexic patients and in a sample of "normal eating" elderly subjects. 96 anorexic subjects were selected in acute and rehabilitation wards (66 women; 81.5 +/- 7 years; 30 men: 81.8 +/- 8 years. The prevalence of anorexia in the sample was 33.3% in women and 26.7% in men. Anorexic subjects were older and more frequently needed help for shopping and cooking. A higher (although not statistically significant) level of comorbidity was present in anorexic subjects. These subjects reported constipation and epigastrium pain more frequently. Nutritional status parameters (MNA, anthropometry, blood parameters) were significantly worst in anorexic subjects whereas CRP was higher. Chewing and swallowing efficiencies were significantly impaired and eating patterns were different for anorexic subjects with a significant reduction of protein rich foods. consequences of anorexia can be extremely serious and deeply affect both patient's mobility, mortality and quality of life. Therefore, it is of utmost importance to perform a special evaluation of the nutritional risk, to constantly evaluate the nutritional status and feeding intake of older patients, to identify and treat the

Objective Anorexia nervosa is a psychiatric illness characterized by low weight, disordered eating, and hallmark neuroendocrine dysfunction. Behavioral phenotypes are defined by predominant restriction or bingeing/purging; binge-eating/purging type anorexia nervosa is associated with poorer outcome. The pathophysiology underlying anorexia nervosa types is unknown, but altered hormones, known to be involved in eating behaviors, may play a role. Method To examine the role of anorexigenic hormones in anorexia nervosa subtypes, we examined serum levels of peptide YY (PYY; total and active [3-36] forms), brain-derived neurotrophic factor (BDNF), and leptin as primary outcomes in women with OSM-5 restricting type anorexia nervosa (n=50), binge-eating/purging type anorexia nervosa (n = 22), and healthy controls (n = 22).1n addition, women completed validated secondary outcome measures of eating disorder psychopathology (Eating Disorder Examination-Questionnaire) and depression and anxiety symptoms (Hamilton Rating Scales for Depression [HDRS] and Anxiety [HARS]). The study samples were collected from May 22, 2004, to February 7, 2012. Results Mean PYY 3-36 and leptin levels were lower and BDNF levels higher in binge-eating/purging type anorexia nervosa than in restricting type anorexia nervosa (all Pvalues anorexia nervosa types were significant (Panorexia nervosa, the anorexigenic hormones PYY, BDNF, and leptin are differentially regulated between the restricting and binge/purge types. Whether these hormone pathways play etiologic roles with regard to anorexia nervosa behavioral types or are compensatory merits further study. PMID:25098834

The roles of corticotrophin-releasing factor (CRF), opioid peptides, leptin and ghrelin in anorexia nervosa (AN) were discussed in this paper. CRF is the key mediator of the hypothalamo-pituitary-adrenal (HPA) axis and also acts at various other parts of the brain, such as the limbic system and the peripheral nervous system. CRF action is mediated through the CRF1 and CRF2 receptors, with both HPA axis-dependent and HPA axis-independent actions, where the latter shows nil involvement of the autonomic nervous system. CRF1 receptors mediate both the HPA axis-dependent and independent pathways through CRF, while the CRF2 receptors exclusively mediate the HPA axis-independent pathways through urocortin. Opioid peptides are involved in the adaptation and regulation of energy intake and utilization through reward-related behavior. Opioids play a role in the addictive component of AN, as described by the “auto-addiction opioids theory”. Their interactions have demonstrated the psychological aspect of AN and have shown to prevent the functioning of the physiological homeostasis. Important opioids involved are β-lipotropin, β-endorphin and dynorphin, which interact with both µ and κ opioids receptors to regulate reward-mediated behavior and describe the higher incidence of AN seen in females. Moreover, ghrelin is known as the “hunger” hormone and helps stimulate growth hormone (GH) and hepatic insulin-like-growth-factor-1(IGF-1), maintaining anabolism and preserving a lean body mass. In AN, high levels of GH due to GH resistance along with low levels of IGF-1 are observed. Leptin plays a role in suppressing appetite through the inhibition of neuropeptide Y gene. Moreover, the CRF, opioid, leptin and ghrelin mechanisms operate collectively at the HPA axis and express the physiological and psychological components of AN. Fear conditioning is an intricate learning process occurring at the level of the hippocampus, amygdala, lateral septum and the dorsal raphe by
Anorexia nervosa (AN) and bulimia nervosa (BN) are related disorders of unknown etiology that most commonly begin during adolescence in women. AN and BN have unique and puzzling symptoms, such as restricted eating or binge-purge behaviors, body image distortions, denial of emaciation, and resistance to treatment. These are often chronic and relapsing disorders, and AN has the highest death rate of any psychiatric disorder. The lack of understanding of the pathogenesis of this illness has hindered the development of effective interventions, particularly for AN. Individuals with AN and BN are consistently characterized by perfectionism, obsessive-compulsiveness, and dysphoric mood. Individuals with AN tend to have high constraint, constriction of affect and emotional expressiveness, ahendonia and asceticism, whereas individuals with BN tend to be more impulsive and sensation seeking. Such symptoms often begin in childhood, before the onset of an eating disorder, and persist after recovery, suggesting they are traits that create a vulnerability for developing an ED. There is growing acknowledgement that neurobiological vulnerabilities make a substantial contribution to the pathogenesis of AN and BN. Considerable evidence suggests that altered brain serotonin (5-HT) function contributes to dysregulation of appetite, mood, and impulse control in AN and BN. Brain imaging studies, using 5-HT specific ligands, show that disturbances of 5-HT function occur when people are ill, and persist after recovery from AN and BN. It is possible that a trait-related disturbance of 5-HT neuronal modulation predates the onset of AN and contributes to premorbid symptoms of anxiety, obsessionality, and inhibition. This dysphoric temperament may involve an inherent dysregulation of emotional and reward pathways which also mediate the hedonic aspects of feeding, thus making these individuals vulnerable to disturbed appetitive behaviors. Restricting food intake may become powerfully

This is an updated version of a previously published review in The Cochrane Library (2005, Issue 2) on 'Megestrol acetate for the treatment of anorexia-cachexia syndrome'. Megestrol acetate (MA) is currently used to improve appetite and to increase weight in cancer-associated anorexia. In 1993, MA was approved by the US Food and Drug Administration for the treatment of anorexia, cachexia or unexplained weight loss in patients with AIDS. The mechanism by which MA increases appetite is unknown and its effectiveness for anorexia and cachexia in neoplastic and AIDS (acquired immunodeficiency syndrome) patients is under investigation. To evaluate the efficacy, effectiveness and safety of MA in palliating anorexia-cachexia syndrome in patients with cancer, AIDS and other underlying pathologies. We sought studies through an extensive search of electronic databases, journals, reference lists, contact with investigators and other search strategies outlined in the methods. The most recent search for this update was carried out in May 2012. Studies were included in the review if they assessed MA compared to placebo or other drug treatments in randomised controlled trials of patients with a clinical diagnosis of anorexia-cachexia syndrome related to cancer, AIDS or any other underlying pathology. Two independent review authors conducted data extraction and evaluated methodological quality. We performed quantitative analyses using appetite and quality of life as a dichotomous variable, and analysed weight gain as continuous and dichotomous variables. We included 35 trials in this update, the same number but not the same trials as in the previous version of the review. The trials comprised 3963 patients for effectiveness and 3180 for safety. Sixteen trials compared MA at different doses with placebo, seven trials compared different doses of MA with other drug treatments and 10 trials compared different doses of MA. Meta-analysis showed a benefit of MA compared with placebo

Full Text Available En el 2000, el Gobierno Nacional de Colombia se comprometió con la Organización de Naciones Unidas (ONU, con el Banco Mundial (BM, con el Fondo Monetario Internacional (FMI y con la organización para la Cooperación y el Desarrollo Económicos (OCDE a cumplir hacia el 2015 con un marco de ocho objetivos, dieciocho metas y cuarenta y ocho indicadores, con el fin de medir los progresos hacia el logro de los Objetivos de Desarrollo del Milenio (ODM. El presente trabajo se concentró en examinar los objetivos referidos a la pobreza. Al analizar el Plan Nacional de Desarrollo (PND 2002-2006 “Hacia un Estado comunitario”, no se observó un enlace directo con la consecución de los logros de los ODM sobre pobreza, ya que ésta no aparece como un objetivo explícito en tal plan. Posteriormente, al analizar el PND 2006-2010 “Estado Concordancia entre el cumplimiento de los Objetivos de Desarrollo del Milenio sobre pobreza, con los Planes Nacionales de Desarrollo de Colombia 2002-2010: evaluación con un modelo de cointegración comunitario: desarrollo para todos”, se encontró que hay una mejora sustancial en el tema de pobreza con respecto al PND anterior. Quizás esto se debe a que –como se anotó antes– en el PND 2002-2006 no se presentó el tema de la pobreza explícitamente, y a que ésta seguía siendo muy alta en el 2003. En dicho plan se presenta el tema de la pobreza como un objetivo general con proyecciones de metas anuales y con un plan de inversiones explícito sobre la reducción de la pobreza. A partir del modelo de cointegración estimado, se infiere que los gastos del gobierno colombiano dedicados al tema de la pobreza en el periodo que abarca los dos últimos PND no han sido suficientes para obtener las metas de ODM que el país se fijó cumplir en el 2015.
The current study demonstrates that recent attempts to equate anorexia nervosa with any form of voluntary self-starvation are not justified. Three arguments are critically reconsidered: That weight phobia was not part of early case reports on anorexia nervosa, that weight phobia should be eliminated from the diagnosis of anorexia nervosa, and that there is a continuity of forms of extreme fasting since the late Middle Ages. A critical approach to the history of eating disorders by interpreting historical sources makes the emergence of anorexia with weight phobia in the middle of the 19th century probable. The criteria for establishing psychiatric diagnoses and the differences between historical types of extreme fasting also support the historical novelty of anorexia nervosa. The etiologic implications of the historical specificity of anorexia nervosa are limited. Research should be directed to better understand self-starvation without weight phobia. 2005 by Wiley Periodicals, Inc.

Studies have shown that a prolonged P-wave dispersion is a risk factor for the development of atrial fibrillation. The aim of this study was to evaluate P-wave dispersion in adolescents with anorexia nervosa at diagnosis. We evaluated electrocardiographic findings, particularly the P-wave dispersion, at initial assessment in 47 adolescents with anorexia nervosa. Comparison of P-wave dispersion between adolescents with anorexia nervosa and controls showed a statistically significant higher P-wave dispersion in patients with anorexia nervosa (72 ± 16.3 msec) when compared to the control group (43.8 ± 9.5 msec). Percent of body weight lost, lower body mass index, and higher weight loss rate in the patients with anorexia nervosa had no effect on P-wave dispersion. Due to the fact that anorexia nervosa has a high mortality rate we believe that cardiac pathologies such as atrial fibrillation must also be considered in the medical evaluation.

We examined the nasopharynx and brain in 17 patients with anorexia nervosa by CT and compared the findings with those of 44 normal subjects and of 5 patients of the same age with marked emaciation caused by various psychiatric disorders. An enlarged nasopharyngeal space with a flattened posterior wall and enlarged lateral pharyngeal recesses were demonstrated in all patients with anorexia nervosa whose weight was lowest at the time of the CT examination, and these CT features regressed or became normal quickly after they had gained some weight. This characteristic enlargement of the nasopharynx and lateral pharyngeal recesses was observed neither in the markedly emaciated patients (2 with schizophrenia, 1 with major depression, 1 with stupor and the other with an extremely unbalanced diet) nor in 44 normal subjects without emaciation. These features were therefore thought to be characteristic and of diagnostic significance. (orig.). With 5 figs., 3 tabs

The purpose of this article is to describe the orbital changes due to lipolysis in anorexia nervosa. We examined a cachectic patient with MR imaging using T1-weighted images before and after contrast enhancement. Orbital fat edema has been observed in extreme forms of cachexia and the CT and MR findings have recently been reported. The imaging appearances have been explained by the disappearance of the fat tissue and the appearance of edema due to a disturbance in the electrolyte fluid balance. In the recent literature particular attention has been paid to the increased lipid peroxidation and lipolysis in anorexia nervosa. These metabolic processes result in an increased permeability of the vessel wall endothelium, which can explain the extravasation of the contrast agent in the orbital fat on MR imaging. (orig.)

Responses in pre-modern eras to anorexia nervosa (as now understood) varied widely, from religious piety and sanctity through fear and superstition. While noting briefly the limited conceptualizations from pre-modern history this article is primarily focused from the late 19th century, commencing with helpful but tentative formulations of anorexia nervosa for early-modern medicine that were laid out, consistently between themselves, by Lesègue, Gull and Osler. Yet that promising biomedical advent was superseded for more than a half-century by deep, internal divisions and bitter rifts that festered between three medical disciplines: neurology; Freudian psychotherapy; and Kraepelinian biological psychiatry. Mid-20th century developments preceded the 1960-1980s' improved understanding of suffering and movement toward effective remediation introduced by Dr. Hilde Bruch.

Peripheral vascular abnormalities caused by a dysregulation between peripheral vasoconstriction and vasodilatation, clinically appearing with Raynaud's phenomenon, have been described in anorexia nervosa but specific characteristics of microcirculation in anorexic patients have not yet been studied. We performed nailfold videocapillaroscopy to assess microcirculatory alteration in anorexic patients and found three different patterns: normal, aspecific and early scleroderma pattern. We also evaluated several laboratory and clinical parameters to better assess our capillaroscopic findings. None of the clinical parameters examined correlated with specific capillaroscopic findings. An increased risk of autoimmune diseases in eating disorder patients has been described. Our results evidenced an association between early scleroderma capillaroscopic pattern and Raynaud's phenomenon that occurs in anorexia nervosa patients, whereas no significant association was found between all three capillaroscopic patterns and the presence of autoantibodies, as well as ESR and CRP values. Our study reveals that patients with AN suffering from RP exhibit NVC findings typical of connective tissue diseases.

Full Text Available The relationship between anorexia nervosa and celiac disease remains an area of ongoing research. Identification of celiac disease in patients with restricted nutritional intake can be challenging since abdominal complaints are a common comorbidity associated with eating disorders and since diagnosis of celiac disease requires a duodenal biopsy while on a gluten containing diet. In this report, we present a 12-year-old female who developed anorexia nervosa and was thereafter diagnosed with celiac disease. The latter diagnosis occurred after a 2-year period of persistent abdominal complaints and duodenal biopsies on three separate occasions. Our case highlights the diagnostic challenge, which may include initially missing the diagnosis, associated with celiac disease in patients who are restricting their nutritional intake, and also the importance of re-testing in patients where gastrointestinal complaints are persistent for extended time periods after refeeding.

To elucidate the potential relationship between classification of emotional faces and impaired central processing in eating disorders and to investigate the potential mediatory role of alexithymia and depression in this relationship. Visual-evoked potentials (VEPs) to emotional faces and classification performance were assessed in 12 anorexic females and matched healthy controls. Patients with anorexia nervosa showed no modulation of emotional face processing and displayed significantly increased N200 amplitudes in response to all emotional categories and decreased VEPs in response to unpleasant emotional faces in the P300 time range as compared with healthy controls. They also made more mistakes in emotional face recognition, in particular, for neutral, sad, and disgusted content. There are marked differences in evoked potentials and emotion recognition performances of patients with anorexia nervosa and controls in facial processing. Differences in brain dynamics might contribute to difficulties in the correct recognition of facially expressed emotions, deficits in social functioning, and in turn the maintenance of eating disorders.

We hypothesised that hippocampal volume would be reduced in underweight anorexia nervosa (AN) and associated with impaired hippocampus-dependent cognitive function. Hippocampal and whole brain volumes were measured in 16 women with AN and 16 matched healthy women using magnetic resonance imaging (MRI) and a manual tracing method. Participants also completed the Doors and People Test of hippocampus-dependent memory and an IQ test. After adjustment for total cerebral volume, there was significant bilateral reduction in hippocampal volume in the AN group (8.2% right; 7.5% left). There was no evidence of impaired hippocampus-dependent cognitive function and no evidence of a relationship between hippocampal volume and clinical features of AN. The reduced hippocampal volume in anorexia nervosa is not associated with changes in cognitive function. To understand the cause and consequence of hippocampal size and function, it will be important to integrate endocrine, neuropsychological and neuroimaging studies.

Para ello se han cultivado cuantitativamente las muestras del lavado broncoalveolar broncoscópico, procedimiento que no siempre es posible. Objetivo. Evaluar la concordancia microbiológica entre muestras respiratorias tomadas por lavado broncoalveolar broncoscópico y no broncoscópico, y establecer si el uso previo de antibióticos y el momento de presentación de la neumonía pueden afectarla. Materiales y métodos. Estudio prospectivo realizado en el Hospital Universitario San Vicente de Paúl, en 38 pacientes con sospecha de neumonía y con asistencia respiratoria mecánica. En todos se practicó el lavado broncoalveolar por fibrobroncoscopia y el lavado no broncoscópico usando un catéter telescopado de punta preformada (Balcath®. Todas las muestras fueron procesadas siguiendo protocolos microbiológicos convencionales. Resultados. Considerando el lavado broncoalveolar por fibrobroncoscopia como patrón de referencia, los cultivos permitieron identificar el agente en 60,5% de los casos. El acuerdo diagnóstico se logró en 82% de los pacientes y 79% de los aislamientos. Utilizando el índice kappa de Cohen, la concordancia general entre los dos métodos fue 0,76 [0,60-0,93]; pero en quienes habían recibido antibióticos previos fue 0,26 [0,05-0,48], versus 1,0 en quienes no lo habían hecho (p<0,0001. La concordancia no difirió significativamente cuando se compararon los casos de neumonía temprana y tardía. Conclusiones. La concordancia general entre los dos métodos de lavado broncoalveolar es buena en pacientes con neumonía y respiración asistida mecánicamente. Sin embargo, el uso previo de antibióticos y no el momento de aparición de la neumonía, disminuye ésta significativamente.

Anorexia and impaired appetite (Dysorexia) are common symptoms with varying causes, and often need no serious medical intervention. Anorexia nervosa (AN) is a chronic psychiatric disease with a high mortality rate. In Traditional Persian Medicine (TPM), anorexia is a condition in which anorexic patients lose appetite due to dystemperament. This review aims to discuss the common points of traditional and conventional approaches rather than introducing Persian medical recommendations suitable for nowadays use. For this purpose, Avicenna's Canon of Medicine, main TPM resources and important databases were reviewed using the related keywords. Despite complex hormonal explanation, etiology of AN in conventional approach is not completely understood. In TPM approach, the etiology and recommended interventions are thoroughly defined based on humoral pathophysiology. In TPM approach, disease states are regarded as the result of imbalances in organs' temperament and humors. In anorexia with simple dystemperament, the physician should attempt to balance the temperament using foods and medicaments which have opposite quality of temperament. Lifestyle, spiritual diseases (neuro - psychological) and gastrointestinal worms are the other causes for reducing appetite. Also, medicines and foods with warm temperaments (such as Pea soup and Mustard) are useful for these patients (cold temperament). Although the pathophysiology of AN in TPM is different in comparison with conventional views, TPM criteria for treatment this disorder is similar to those of current medicine. Recommending to have spiritual support and a healthy lifestyle are common in both views. Simple safe interventions recommended by TPM may be considered as alternative medical modalities after being confirmed by well-designed clinical trials.

Eating disorders frequently occur in conjunction with autism spectrum disorders, posing diagnostic and therapeutic difficulties. The comorbidity of anorexia nervosa and Asperger syndrome is a significant clinical complication and has been associated with a poorer prognosis. The authors are presenting the cases of an eleven-year-old girl and a five-and-a-half-year-old girl with comorbid eating disorders and Asperger syndrome.

Amenorrhea is a current criterion for the diagnosis of anorexia nervosa (AN) according to the DSM-IV-TR. Nevertheless, when comparing groups of patients who fulfill all the criteria of this manual for AN and groups of women who show them all but amenorrhea, some studies did not find significant differences in the psychopathology typically associated with AN. The purpose of our study was to compare both groups in demographic, anthropometric, psychological and psychopathological variables. Ther...

Minoxidil is a potent antihypertensive used as an adjunctive agent in refractory hypertension. It exerts an antihypertensive effect through two mechanisms: selective arterial vasodilation by activation of potassium channels in the vascular smooth muscle and stimulation of carotid and aortic baroreceptors, leading to downstream release of renin and norepinephrine. Although frequently cited in reviews of antihypertensive agents, limited data about the use of minoxidil in neonates are available. We describe an infant girl, born at 35 weeks of gestation, who was diagnosed with idiopathic hypertension after extensive diagnostic evaluation. Adequate blood pressure control was not achieved with captopril, amlodipine, and clonidine. Oliguria secondary to captopril and rapid-onset congestive heart failure due to persistent hypertension led to the introduction of intravenous agents labetalol and nitroprusside. Although adequate blood pressure control was achieved, attempts to transition back to oral agents were unsuccessful, prompting the use of minoxidil as an alternative agent. Although good blood pressure control was achieved, the infant's oral intake plummeted from 210 to 63 ml/kg/day. The anorexia quickly resolved after stopping minoxidil, and she was discharged home at 5 months of age receiving propranolol, amlodipine, and doxazosin. Use of the Naranjo adverse drug reaction probability scale indicated a definite relationship (score of 10) between the patient's development of anorexia and minoxidil therapy. To our knowledge, there have been no previous reports of minoxidil-associated anorexia in preterm or term infants. Clinicians should be aware that anorexia is a possible adverse effect of minoxidil in this patient population when initiating the drug in similar patients. © 2014 Pharmacotherapy Publications, Inc.

Anorexia nervosa (AN) and bulimia nervosa (BN) are multifactorial diseases, which are among the most prevalent disorders in child and adolescent psychiatry. Aesthetic sports are often considered as a risk factor for the development of an eating disorder. The present professorial dissertation for the first time demonstrates no higher risk for competitive athletes aged 12 to 18 years to develop an eating disorder. Research shows that psychiatric comorbidity is a very unfavorable prognostic ...

Ample evidence suggests a rising incidence of anorexia nervosa and bulimia over the past few decades. Correspondingly, medical knowledge about the etiology, symptomatology and treatment of these eating disorders has increased. Often the front line health-care workers who treat these disorders, family physicians are in a key position for early detection and prevention of these eating disorders. An adequate understanding of relevant risk factors, symptoms and signs may allow the physician to pr...

Anorexia nervosa has the highest mortality rate of any psychiatric disorder. Many of the deaths are attributable to medical complications which arise as the malnutrition and weight loss worsens. Every body system may be adversely affected by anorexia nervosa. Yet, remarkably, most of the medical complications of anorexia nervosa are treatable and reversible with optimal medical care, as part of a multidisciplinary team who are often involved in the care of these patients. Herein, we will describe the medical complications of anorexia nervosa and their treatments.

Patients with anorexia nervosa exhibit higher levels of behaviours typically associated with autism-spectrum disorder (ASD), but the neural basis is unclear. We sought to determine whether elevated autistic traits in women with anorexia nervosa may be reflected in cortical morphology. We used voxel-based morphometry (VBM) to examine regional grey matter volumes in high-resolution MRI structural brain scans in women with anorexia nervosa and matched healthy controls. The Autism-spectrum Quotient (AQ) scale was used to assess autistic traits. Women with anorexia nervosa ( n = 25) had higher AQ scores and lower bilateral superior temporal sulcus (STS) grey matter volumes than the control group ( n = 25). The AQ scores correlated negatively with average left STS grey matter volume in women with anorexia nervosa. We did not control for cognitive ability and examined only women with ongoing anorexia nervosa. Elevated autistic traits in women with anorexia nervosa are associated with morphometric alterations of brain areas linked to social cognition. This finding provides neurobiological support for the behavioural link between anorexia nervosa and ASD and emphasizes the importance of recognizing autistic traits in preventing and treating anorexia nervosa.

Anxiety disorders and anorexia nervosa are frequently acknowledged to be highly comorbid conditions, but still, little is known about the clinical and aetiological cohesion of specific anxiety diagnoses and anorexia nervosa. Using the comprehensive Danish population registers, we aimed to determine the risk of anorexia nervosa in patients with register-detected severe anxiety disorders. We also explored whether parental psychopathology was associated with offspring's anorexia nervosa. Anxiety disorders increased the risk of subsequent anorexia nervosa, with the highest risk observed in obsessive-compulsive disorder. Especially, male anxiety patients were at an increased risk for anorexia nervosa. Furthermore, an increased risk was observed in offspring of fathers with panic disorder. A diagnosis of an anxiety disorder, specifically obsessive-compulsive disorder, constitutes a risk factor for subsequent diagnosis of anorexia nervosa. These observations support the notion that anxiety disorders and anorexia nervosa share etiological mechanisms and/or that anxiety represents one developmental pathway to anorexia nervosa.

Objective The Diagnostic and Statistical Manual of Mental Disorders (DSM) is designed primarily as a clinical tool. Yet high rates of diagnostic “crossover” among the anorexia nervosa subtypes and bulimia nervosa may reflect problems with the validity of the current diagnostic schema, thereby limiting its clinical utility. This study was designed to examine diagnostic crossover longitudinally in anorexia nervosa and bulimia nervosa to inform the validity of the DSM-IV-TR eating disorders classification system. Method A total of 216 women with a diagnosis of anorexia nervosa or bulimia nervosa were followed for 7 years; weekly eating disorder symptom data collected using the Eating Disorder Longitudinal Interval Follow-Up Examination allowed for diagnoses to be made throughout the follow-up period. Results Over 7 years, the majority of women with anorexia nervosa experienced diagnostic crossover: more than half crossed between the restricting and binge eating/purging anorexia nervosa subtypes over time; one-third crossed over to bulimia nervosa but were likely to relapse into anorexia nervosa. Women with bulimia nervosa were unlikely to cross over to anorexia nervosa. Conclusions These findings support the longitudinal distinction of anorexia nervosa and bulimia nervosa but do not support the anorexia nervosa subtyping schema. PMID:18198267

There is widespread use of the Internet to promote anorexia as a lifestyle choice. Pro-anorexia content can be harmful for people affected or at risk of having anorexia. That movement is actively engaged in sharing photos on social networks such as Flickr. To study the characteristics of the online communities engaged in disseminating content that encourages eating disorders (known as "pro-anorexia") and to investigate if the posting of such content is discouraged by the posting of recovery-oriented content. The extraction of pro-anorexia and pro-recovery photographs from the photo sharing site Flickr pertaining to 242,710 photos from 491 users and analyzing four separate social networks therein. Pro-anorexia and pro-recovery communities interact to a much higher degree among themselves than what is expected from the distribution of contacts (only 59-72% of contacts but 74-83% of comments are made to members inside the community). Pro-recovery users employ similar words to those used by pro-anorexia users to describe their photographs, possibly in order to ensure that their content appears when pro-anorexia users search for images. Pro-anorexia users who are exposed to comments from the opposite camp are less likely to cease posting pro-anorexia photographs than those who do not receive such comments (46% versus 61%), and if they cease, they do so approximately three months later. Our observations show two highly active communities, where most interaction is within each community. However, the pro-recovery community takes steps to ensure that their content is visible to the pro-anorexia community, both by using textual descriptions of their photographs that are similar to those used by the pro-anorexia group and by commenting to pro-anorexia content. The latter activity is, however, counterproductive, as it entrenches pro-anorexia users in their stance. Our results highlight the nature of pro-anorexia and pro-recovery photo sharing and accentuate the need for

To identify clinical or cognitive measures either predictive of illness trajectory or altered with sustained weight recovery in adult women with anorexia nervosa. Participants were recruited from prior studies of women with anorexia nervosa (AN-C) and in weight-recovery following anorexia nervosa (AN-WR). Participants completed a neuropsychological battery at baseline and clinical assessments at both baseline and follow-up. Groups based on clinical outcome (continued eating disorder, AN-CC; newly in recovery, AN-CR; sustained weight-recovery, AN-WR) were compared by using one-way ANOVAs with Bonferroni-corrected post hoc comparisons. Women with continued eating disorder had poorer neuropsychological function and self-competence at baseline than AN-CR. AN-CR showed changes in depression and externalizing bias, a measure of self-related attributions. AN-WR differed from both AN-CC and AN-CR at baseline in externalizing bias, but only from AN-CC at outcome. Neuropsychological function when recently ill may be a prognostic factor, while externalizing bias may provide a clinical target for recovery.

Full Text Available Anorexia nervosa is a complex eating disorder characterized by the voluntary reduction, and subsequent maintenance, of body weight at a level below 85% of optimal body weight, a pathological fear of food and weight gain, and disturbance of experience of weight and body shape. Development, sustainability and complexity of symptoms depend upon different biological, psychological and social factors. The aim of the paper is to present risk factors that can significantly contribute to the development and severity of the symptoms of anorexia nervosa. This review paper presents the key factors in the development of the disorder. Attachment styles, perfectionism and concerns about body shape, as core psychological factors for development and severity of symptoms, are the principle areas discussed. Lack of self-esteem and self-confidence, unresolved emotional issues, high, unrealistic standards and ideals of physical appearance to which people rigidly hold and which they persistently and consistently attempt to reach, dissatisfaction with body shape, and significant discrepancy between perceived and ideal body image are all associated with maladaptive behavior and attitudes towards food, and often precede the diagnosis of the disorder. The review of research indicates that insecure emotional attachment styles, perfectionism and concern about body shape significantly correlate with symptoms of anorexia nervosa and represent risk and maintaining factors of the disorder. Focus on these problems can significantly contribute to more comprehensive prevention and treatment of the disorder.

Anorexia is commonly present in persons with cancer and a major component of cancer cachexia. There are multiple causes of anorexia in cancer. Peripherally, these can be due to (i) substances released from or by the tumour, e.g. pro-inflammatory cytokines, lactate, and parathormone-related peptide; (ii) tumours causing dysphagia or altering gut function; (iii) tumours altering nutrients, e.g. zinc deficiency; (iv) tumours causing hypoxia; (v) increased peripheral tryptophan leading to increased central serotonin; or (vi) alterations of release of peripheral hormones that alter feeding, e.g. peptide tyrosine tyrosine and ghrelin. Central effects include depression and pain, decreasing the desire to eat. Within the central nervous system, tumours create multiple alterations in neurotransmitters, neuropeptides, and prostaglandins that modulate feeding. Many of these neurotransmitters appear to produce their anorectic effects through the adenosine monophosphate kinase/methylmalonyl coenzyme A/fatty acid system in the hypothalamus. Dynamin is a guanosine triphosphatase that is responsible for internalization of melanocortin 4 receptors and prostaglandin receptors. Dynamin is up-regulated in a mouse model of cancer anorexia. A number of drugs, e.g. megestrol acetate, cannabinoids, and ghrelin agonists, have been shown to have some ability to be orexigenic in cancer patients. PMID:26675762

Full Text Available The aim of this paper was to conduct a systematic review of body fat distribution before and after partial and complete weight restoration in individuals with anorexia nervosa. Literature searches, study selection, method development and quality appraisal were performed independently by two authors, and data was synthesized using a narrative approach. Twenty studies met the inclusion criteria and were consequently analyzed. The review had five main findings. First, during anorexia nervosa adolescent females lose more central body fat, while adult females more peripheral fat. Second, partial weight restoration leads to greater fat mass deposition in the trunk region than other body regions in adolescent females. Third, after short-term weight restoration, whether partial or complete, adults show a central adiposity phenotype with respect to healthy age-matched controls. Fourth, central fat distribution is associated with increased insulin resistance, but does not adversely affect eating disorder psychopathology or cause psychological distress in female adults. Fifth, the abnormal central fat distribution seems to normalize after long-term maintenance of complete weight restoration, indicating that preferential central distribution of body fat is a transitory phenomenon. However, a discrepancy in the findings has been noted, especially between adolescents and adults; besides age and gender, these appear to be related to differences in the methodology and time of body composition assessments.

The rate of adolescents presenting with anorexia nervosa (AN) is increasing. Medically unstable adolescents are admitted to the hospital for nutrition restoration. A lack of global consensus on appropriate refeeding practices of malnourished patients has resulted in inconsistent refeeding practices. Refeeding hypophosphatemia (RH) is the most common complication associated with refeeding the malnourished patient. This review sought to identify the range of refeeding rates adopted globally and the implication that total energy intake and malnutrition may have on RH while refeeding adolescents with anorexia nervosa. Studies were identified by a systematic electronic search of medical databases from 1980 to September 2012. Seventeen publications were identified, including 6 chart reviews, 1 observational study, and 10 case reports, with a total of 1039 subjects. The average refeeding energy intake was 1186 kcal/d, ranging from 125-1900 kcal/d, with a mean percentage median body mass index (% mBMI) of 78%. The average incidence rate of RH was 14%. A significant correlation between malnutrition (% mBMI) and post-refeeding phosphate was identified (R (2) = 0.6, P = .01). This review highlights the disparity in refeeding rates adopted internationally in treating malnourished adolescents with anorexia nervosa. Based on this review, the severity of malnutrition seems to be a marker for the development of RH more so than total energy intake.

To explore the association between specific maternal characteristics, maternal perceptions of toddler temperament, and infantile anorexia. Three groups of toddlers (aged 12-37 months) participated in this study: toddlers with infantile anorexia (n = 34), picky eaters (n = 34), and healthy eaters (n = 34). Mothers completed questionnaires that assessed their own eating attitudes, marital satisfaction, and their toddlers' temperament, and an interview that explored their attachment representations. Mothers and toddlers were videotaped during a feeding session, and toddlers were weighed and measured. Temperament ratings differentiated between infantile anorexics and healthy eaters (p unstoppable ratings. Mothers of anorexics showed greater attachment insecurity than mothers of healthy eaters (p < .05), but they demonstrated neither overt eating pathology nor less marital satisfaction than the other groups. Thirty-nine percent of variance in feeding conflict was explained by toddlers' diagnoses, temperament ratings, and maternal characteristics. Twenty-one percent of variance in toddlers' weights was explained by temperament ratings and feeding conflict. Maternal characteristics and perceptions of their toddlers' temperament characteristics should be addressed in treatment for infantile anorexia.

Anorexia can occur as a serious complication of disease. Increasing evidence suggests that inflammation plays a major role, along with a hypothalamic dysregulation characterized by locally elevated serotonin levels. The present study was undertaken to further explore the connections between peripheral inflammation, anorexia and hypothalamic serotonin metabolism and signaling pathways. First, we investigated the response of two hypothalamic neuronal cell lines to TNFα, IL-6 and LPS. Next, we studied transcriptomic changes and serotonergic activity in the hypothalamus of mice after intraperitoneal injection with TNFα, IL-6 or a combination of TNFα and IL-6. In vitro, we showed that hypothalamic neurons responded to inflammatory mediators by releasing cytokines. This inflammatory response was associated with an increased serotonin release. Mice injected with TNFα and IL-6 showed decreased food intake, associated with altered expression of inflammation-related genes in the hypothalamus. In addition, hypothalamic serotonin turnover showed to be elevated in treated mice. Overall, our results underline that peripheral inflammation reaches the hypothalamus where it affects hypothalamic serotoninergic metabolism. These hypothalamic changes in serotonin pathways are associated with decreased food intake, providing evidence for a role of serotonin in inflammation-induced anorexia.

Aims and method A community intensive treatment service for severe anorexia nervosa is described. The service is multidisciplinary but driven by a focus on psychological formulation. Psychological and dietetic interventions are grounded in a process of active risk management. Evaluations of safety, cost and acceptability of the service are described. Results Patients are highly satisfied with their care. A relatively low mortality rate for such a high-risk population was observed. In-patient bed use and costs were substantially reduced. Clinical implications There is a case for greater use of intensive community care for patients with severe anorexia nervosa, as it can be acceptable to patients, relatively safe and cost less than admission.

Anorexia nervosa often begins in adolescence, and there is a growing body of quantitative literature looking at the efficacy of treatment for adolescents. However, qualitative research has a valuable contribution to make to the understanding of treatment and recovery. This paper aims to review qualitative studies on the experience of treatment and recovery for adolescents with anorexia nervosa. Key themes from the 11 studies identified the role of family, peers and professionals, family therapy, the inpatient setting, emphasis on physical versus psychological and conceptualisation of recovery. Future studies would benefit from relating their findings to adolescent theory and considering reflexivity. Implications for clinical practice are also discussed.

The need for novel approaches to understanding and treating anorexia nervosa (AN) is well recognized. The aim of this paper is to describe an integrative bio-psycho-social theory of maintaining factors in AN. We took a triangulation approach to develop a clinically relevant theory with face validity and internal consistency. We developed theoretical ideas from our clinical practice and reviewed theoretical ideas within the eating disorders and wider bio-psycho-social literature. The synthesis of these ideas and concepts into a clinically meaningful framework is described here. We suggest eight key factors central to understanding the maintenance and treatment resistance of anorexia nervosa: genetic or experiential predisposing factors; dysfunctional feelings processing and regulation systems; excessive vulnerable feelings; 'feared self' beliefs; starvation as a maladaptive physiological feelings regulation mechanism; maladaptive psychological coping modes; maladaptive social behaviour; and unmet physical and psychological core needs. Each of these factors serves to maintain the disorder. The concept of universal physical and psychological core needs can provide an underpinning integrative framework for working with this distinctly physical and psychological disorder. This framework could be used within any treatment model. We suggest that treatments which help address the profound lack of trust, emotional security and self-acceptance in this patient group will in turn address unmet needs and improve well-being. Copyright © 2016 John Wiley & Sons, Ltd. The concept of unmet physical and psychological needs can be used as an underlying integrative framework for understanding and working with this patient group, alongside any treatment model. A functional understanding of the neuro-biological, physiological and psychological mechanisms involved in anorexia nervosa can help patients reduce self-criticism and shame.

It is well-established that prostaglandins (PGs) affect tumorigenesis, and evidence indicates that PGs also are important for the reduced food intake and body weight loss, the anorexia-cachexia syndrome, in malignant cancer. However, the identity of the PGs and the PG producing cyclooxygenase (COX) species responsible for cancer anorexia-cachexia is unknown. Here, we addressed this issue by transplanting mice with a tumor that elicits anorexia. Meal pattern analysis revealed that the anorexia in the tumor-bearing mice was due to decreased meal frequency. Treatment with a non-selective COX inhibitor attenuated the anorexia, and also tumor growth. When given at manifest anorexia, non-selective COX-inhibitors restored appetite and prevented body weight loss without affecting tumor size. Despite COX-2 induction in the cerebral blood vessels of tumor-bearing mice, a selective COX-2 inhibitor had no effect on the anorexia, whereas selective COX-1 inhibition delayed its onset. Tumor growth was associated with robust increase of PGE(2) levels in plasma - a response blocked both by non-selective COX-inhibition and by selective COX-1 inhibition, but not by COX-2 inhibition. However, there was no increase in PGE(2)-levels in the cerebrospinal fluid. Neutralization of plasma PGE(2) with specific antibodies did not ameliorate the anorexia, and genetic deletion of microsomal PGE synthase-1 (mPGES-1) affected neither anorexia nor tumor growth. Furthermore, tumor-bearing mice lacking EP(4) receptors selectively in the nervous system developed anorexia. These observations suggest that COX-enzymes, most likely COX-1, are involved in cancer-elicited anorexia and weight loss, but that these phenomena occur independently of host mPGES-1, PGE(2) and neuronal EP(4) signaling.

Medical record review to recover missing data in a Portuguese birth cohort: agreement with self-reported data collected by questionnaire and inter-rater variability Revisión de registros médicos para recuperar datos incompletos en una cohorte de nacimiento portuguesa: concordancia con datos recogidos por cuestionario y variabilidad interobservador
Full Text Available Objectives: To assess the yield of medical record review to recover missing data originally collected by questionnaire, to analyze the agreement between these two data sources and to determine interobserver variability in clinical record review. Methods: We analyzed data from a birth cohort of 8,127 women who were consecutively recruited after giving birth from 2005-2006. Recruitment was conducted at all public maternity units of Porto, Portugal. We reviewed the medical records of 3,657 women with missing data in the baseline questionnaire and assessed agreement between these two sources by using information from participants with data from both sources. Interobserver variability was assessed by using 400 randomly selected clinical records. Results: Data on pregnancy complications and maternal anthropometric parameters were successfully recovered. Agreement between the questionnaire and records in family history data was fair, particularly for cardiovascular disease [k=0.27; 95% confidence interval (95%CI: 0.23-0.32]. The highest agreement was observed for personal history of diabetes (k=0.82; 95%CI 0.70-0.93, while agreement for hypertension was moderate (k=0.60; 95%CI 0.50-0.69. Discrepancies in prepregnancy body mass index classes were observed in 10.3% women. Data were highly consistent between the two reviewers, with the highest agreement found for gestational diabetes (k=1.00 and birth weight (99.5% concordance. Conclusion: Data from the medical records and questionnaire were concordant with regard to pregnancy and well-known risk factors. The low interobserver variability did not threaten the precision of our data.Objetivo: Evaluar el rendimiento de la revisión de registros médicos para completar datos originalmente recogidos por cuestionario, y analizar la concordancia entre ambas fuentes de datos y la variabilidad interobservador en la revisión de registros médicos.

Voluntary wheel running (WR) is a form of physical activity in rodents that influences ingestive behavior. The present report describes an anorexic behavior triggered by the simultaneous introduction of a novel diet and WR. This study examined the sequential, compared with the simultaneous, introduction of a novel high-fat (HF) diet and voluntary WR in rats of three different ages and revealed a surprising finding; the simultaneous introduction of HF food and voluntary WR induced a behavior in which the animals chose not to eat although food was available at all times. This phenomenon was apparently not due to an aversion to the novel HF diet because introduction of the running wheels plus the HF diet, while continuing the availability of the normal chow diet did not prevent the anorexia. Moreover, the anorexia was prevented with prior exposure to the HF diet. In addition, the anorexia was not related to extent of WR but dependent on the act of WR. The introduction a HF diet and locked running wheels did not induce the anorexia. This voluntary anorexia was accompanied by substantial weight loss, and the anorexia was rapidly reversed by removal of the running wheels. Moreover, the HF/WR-induced anorexia is preserved across the age span despite the intrinsic decrease in WR activity and increased consumption of HF food with advancing age. The described phenomenon provides a new model to investigate anorexia behavior in rodents. Copyright © 2011 Elsevier Inc. All rights reserved.

This article explores the relationship between eating disorders and reading behaviors, arguing that there is a meaningful difference in a minority of readers' approach to and understanding of anorexia life-writing, and of literary texts more broadly. To illuminate this distinction, this article begins by considering the reported deleterious influence of Marya Hornbacher's anorexia memoir, Wasted, elaborating the ways Hornbacher offers a positive presentation of anorexia nervosa that may, intentionally or not, induce certain readers to "try it" themselves. This is followed by an exploration of how Hornbacher's own reading praxis is implicated in a discursive feedback loop around anorexia narratives. It concludes with a discussion of disordered reading attitudes in relation to the emergence of the "pro-anorexia" phenomenon.

The anorexia of aging was first recognized as a physiological syndrome 30 years ago. Its major causes are an alteration in fundal compliance with an increase in antral stretch and enhanced cholecystokinin activity leading to increased satiation.This anorexia leads to weight loss in aging persons and is one of the component causes of the aging related sarcopenia. This physiological anorexia also increases the risk of more severe anorexia when an older person has an increase in inflammatory cytokines such as occurs when they have an illness. This results in an increase in the anorexia due to cachexia in older persons. © 2017 The Authors.

Behavioral eating disorders (BED's) have shown an intense growth in the last years. They are considered to be caused by multiple factors, showing a bio-psycho-socio-cultural etiology. Although there are clinical signs that could alert the physician and allow an early diagnosis, their final diagnosis must meet certain criteria set in the DSM-IV (1994). Despite the fact that anorexia nervosa and bulimia nervosa in their typical forms, are the most known, there are atypical or incomplete forms of both that should be kept in mind when making the diagnosis. Anorexia nervosa is accompanied by somatic-nutritional problems that may condition the patient's life, requiring specific nutritional care. Bulimia nervosa is often accompanied by medical complications that require an exhaustive assessment. As for the nutritional support in anorexia nervosa, this must be proportional to the nutritional status of the patient and there should be no hesitation to resort to artificial nutrition using enteral nutrition through a tube in the case of severe malnutrition. In these cases there must be careful monitoring for the appearance of the re-nutrition syndrome, and this can be avoided by the slow and progressive administration of energetic nutrients, with special precautions in the supply of carbohydrates, and administering an adequate supplement of vitamins and electrolytes. Patients with a BED require a multi-disciplinary care with the simultaneous and coordinated action of a team of professionals. This type of care coupled with the experience of the team with regard to BED's and their treatment, and together with other actions and situations, may favor the final prognosis of a patient with a BED.

The aim of this paper was to analyze medical utilization patterns of female patients with anorexia nervosa before their first inpatient care visit for anorexia nervosa using the National Health Insurance Research Database (NHIRD) of Taiwan. We selected female anorexia nervosa patients (n=239) and control participants hospitalized for peptic ulcers (n=478) or appendectomy (n=478) who were matched by age and incident year from two subsets of the NHIRD. The number of visits, specialists, diagnosis distribution, and selected procedures used in ambulatory services during the 2-year period before the index admission were identified and compared. Healthcare service expenditures were also analyzed. Compared to the control groups, the female anorexia nervosa patients used more outpatient services (anorexia nervosa, 58.6±45.0 visits; peptic ulcers, 45.3±37.3 visits; appendectomy, 32.5±26.0 visits), mainly due to psychiatric visits. Anorexia nervosa patients were more likely to have received a diagnosis of digestive, endocrine/metabolic, and mental disorders than patients in the control groups. Although nearly equal percentages of patients in the three groups had obtained a diagnosis of a digestive disease, anorexia nervosa patients received digestive disease diagnoses with greater frequency. We posit that the various physical symptoms of anorexia nervosa patients and physicians' low level of suspicion of anorexia nervosa led to delayed diagnoses and greater medical utilization than that of the controls groups. Education to raise awareness of anorexia nervosa and other eating disorders among physicians is warranted. Copyright © 2017 Elsevier Inc. All rights reserved.
Full Text Available Abstract Background The compulsory treatment of anorexia nervosa is a contentious issue. Research suggests that psychiatrists have a range of attitudes towards patients suffering from anorexia nervosa, and towards the use of compulsory treatment for the disorder. Methods A postal self-completed attitudinal questionnaire was sent to senior psychiatrists in the United Kingdom who were mostly general adult psychiatrists, child and adolescent psychiatrists, or psychiatrists with an interest in eating disorders. Results Respondents generally supported a role for compulsory measures under mental health legislation in the treatment of patients with anorexia nervosa. Compared to 'mild' anorexia nervosa, respondents generally were less likely to feel that patients with 'severe' anorexia nervosa were intentionally engaging in weight loss behaviours, were able to control their behaviours, wanted to get better, or were able to reason properly. However, eating disorder specialists were less likely than other psychiatrists to think that patients with 'mild' anorexia nervosa were choosing to engage in their behaviours or able to control their behaviours. Child and adolescent psychiatrists were more likely to have a positive view of the use of parental consent and compulsory treatment for an adolescent with anorexia nervosa. Three factors emerged from factor analysis of the responses named: 'Support for the powers of the Mental Health Act to protect from harm'; 'Primacy of best interests'; and 'Autonomy viewed as being preserved in anorexia nervosa'. Different scores on these factor scales were given in terms of type of specialist and gender. Conclusion In general, senior psychiatrists tend to support the use of compulsory treatment to protect the health of patients at risk and also to protect the welfare of patients in their best interests. In particular, eating disorder specialists tend to support the compulsory treatment of patients with anorexia nervosa

OBJECTIVE Although anorexia nervosa has a high mortality rate, our understanding of the timing and predictors of mortality in eating disorders is limited. The authors investigated mortality in a long-term study of patients with eating disorders. METHOD Beginning in 1987, 246 treatment-seeking female patients with anorexia nervosa or bulimia nervosa were interviewed every 6 months for a median of 9.5 years to obtain weekly ratings of eating disorder symptoms, comorbidity, treatment participation, and psychosocial functioning. From January 2007 to December 2010 (median follow-up of 20 years), vital status was ascertained with a National Death Index search. RESULTS Sixteen deaths (6.5%) were recorded (lifetime anorexia nervosa, N=14; bulimia nervosa with no history of anorexia nervosa, N=2). The standardized mortality ratio was 4.37 (95% CI=2.4-7.3) for lifetime anorexia nervosa and 2.33 (95% CI=0.3-8.4) for bulimia nervosa with no history of anorexia nervosa. Risk of premature death among patients with lifetime anorexia nervosa peaked within the first 10 years of follow-up, resulting in a standardized mortality ratio of 7.7 (95% CI=3.7-14.2). The standardized mortality ratio varied by duration of illness and was 3.2 (95% CI=0.9-8.3) for patients with lifetime anorexia nervosa for 0 to 15 years (4/119 died), and 6.6 (95% CI=3.2-12.1) for those with lifetime anorexia nervosa for >15 to 30 years (10/67 died). Multivariate predictors of mortality included alcohol abuse, low body mass index, and poor social adjustment. CONCLUSIONS These findings highlight the need for early identification and intervention and suggest that a long duration of illness, substance abuse, low weight, and poor psychosocial functioning raise the risk for mortality in anorexia nervosa.

To evaluate gastric emptying, 20 patients with anorexia nervosa were given 150 μCi of Tc-99m triethylene tetraamine polystyrene resin in cereal and were imaged in the supine position. Data were accumulated at 5-minute intervals to determine the gastric emptying time (GET). The GET results were divided into three categories: prolonged (10 patients); rapid (eight); and normal (two). Although all patients had symptoms of gastric dysfunction, only 50% had prolonged GET. This study allows the objective documentation of gastric emptying and the separation of patients with rapid or normal GET from those with prolonged GET, who might benefit from metoclopramide

The purpose of this article is to outline a model of anorexia nervosa (AN) as a disorder of psychological inflexibility, motivated by an insatiable desire for prediction and control with related intolerance for uncertainty. We describe preliminary data that provide initial support for this conceptualization and point to the ways in which mindfulness and acceptance-based strategies might be particularly useful for treating AN. This article is not intended to be an exhaustive literature review, rather a conceptual framework to guide future research and treatment development.

Full Text Available Anorexia Nervosa (AN usually follows a prolonged course accompanied by significant morbidity and high mortality. AN patients have been found to have elevated and attempted suicide rates, with suicide being the second most common cause of death in AN after the complications of the disorder itself. The suicide risk in AN is similar to that in major depression or conduct disorder and linked mainly to longer duration of illness, lower weight, bingeing and purging, impulsivity-related manifestations, comorbid substance abuse, and affective disorder. This paper reviews suicidal tendency and disturbed body image, death and eating disorders, and attachment and death with clinical implications related to AN.

Full Text Available 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.
La anorexia es uno de los síntomas más comunes en los enfermos con cáncer avanzado y se manifiesta con pérdida de apetito por saciedad. Por otro lado, la caquexia se describe en aquellos enfermos con pérdida de peso involuntaria. El proceso canceroso produce un desequilibrio en el balance energético al disminuir la ingesta y aumentar el catabolismo, produciéndose un balance netamente negativo. Se observan diferentes factores que determinan a la caquexia, desde los desequilibrios metabólicos p...

In this chapter we have reviewed the evidence for physiological anorexia of aging and stressed that its pathophysiology involves both central and peripheral mechanisms. Early satiation in the older person appears to involve signals predominantly arising in the stomach. The increased feeling of satiety in older persons is mainly related to changes in the central feeding drive, in particular a decrease in the opioid rewarding properties for fatty foods. Increased cytokines, secondary to inflammatory conditions which are common in old age, may further increase the anorexia seen in older persons. Leptin, the fat hormone, is an excellent indicator of fat mass in women, in whom leptin concentrations correlate with the MNA. In men, testosterone inhibits leptin, and the fall in testosterone with age results in an increase in leptin concentrations. In males the MNA is not related to leptin concentrations. Finally, we have examined the interrelation of two nutritional screening indices, MNA and SCALES. The two indices were well correlated and were both predictive of poor basic function. We conclude that the MNA is an excellent predictor of nutritional status. These findings suggest that malnutrition is a major predictor of frailty or the "failure to thrive" syndrome in older persons. Depression is a major cause of poor nutritional status in older persons.

The scope of this study is to identify and contextualize aspects of the therapeutic itineraries of patients treated at a university medical clinic specialized in nervous anorexia and bulimia. For this purpose, an attempt was made to reconstitute the succession of events triggered in 20 respondents and their families with the classification of anorexia and bulimia as "health problems." The narratives were analyzed in order to link the individual experiences and the social context of their occurrence (organization of health services, characteristics of treatment and medical knowledge and characteristics of contemporary subjectivity), in light of the theoretical studies of Public Health and Psychoanalysis. Data analysis revealed that these itineraries arise from connections and disconnections between two distinct approaches: one that organizes the management of patients and the other governing the conduct of health institutions and families. If the latter presuppose a quest for health, this is not what primarily concerns the individuals in question. Their refusal to moderate their own eating disorders is notable on their itineraries, and indicates the functionality of those practices. Such practices play a part in the reconstruction of their self-images.

Animals exhibit a rapid and sustained anorexia when fed a diet that is deficient in a single indispensable amino acid (IAA). The chemosensor for IAA deficiency resides within the anterior piriform cortex (APC). Although the cellular and molecular mechanisms by which the APC detects IAA deficiency are well established, the efferent neural pathways that reduce feeding in response to an IAA-deficient diet remain to be fully characterized. In the present work, we investigated whether 1) central melanocortin signaling is involved in IAA deficiency-induced anorexia (IAADA) and 2) IAADA engages other key appetite-regulating neuronal populations in the hypothalamus. Rats and mice that consumed a valine-deficient diet (VDD) for 2-3 wk exhibited marked reductions in food intake, body weight, fat and lean body mass, body temperature, and white adipose tissue leptin gene expression, as well as a paradoxical increase in brown adipose tissue uncoupling protein-1 mRNA. Animals consuming the VDD had altered hypothalamic gene expression, typical of starvation. Pharmacological and genetic blockade of central melanocortin signaling failed to increase long-term food intake in this model. Chronic IAA deficiency was associated with a marked upregulation of corticotropin-releasing hormone expression in the lateral hypothalamus, particularly in the parasubthalamic nucleus, an area heavily innervated by efferent projections from the APC. Our observations indicate that the hypothalamic melanocortin system plays a minor role in acute, but not chronic, IAADA and suggest that the restraint on feeding is analogous to that observed after chronic dehydration.

Older people frequently fail to ingest adequate amount of food to meet their essential energy and nutrient requirements. Anorexia of aging, defined by decrease in appetite and/or food intake in old age, is a major contributing factor to under-nutrition and adverse health outcomes in the geriatric population. This disorder is indeed highly prevalent and is recognized as an independent predictor of morbidity and mortality in different clinical settings. Even though anorexia is not an unavoidable consequence of aging, advancing age often promotes its development through various mechanisms. Age-related changes in life-style, disease conditions, as well as social and environmental factors have the potential to directly affect dietary behaviors and nutritional status. In spite of their importance, problems related to food intake and, more generally, nutritional status are seldom attended to in clinical practice. While this may be the result of an "ageist" approach, it should be acknowledged that simple interventions, such as oral nutritional supplementation or modified diets, could meaningfully improve the health status and quality of life of older persons.

Full Text Available Anorexia Nervosa is a chronic, severe psychiatric illness characterized with life threatening weight loss. Patients with eating disorder almost devote their lives to lose weight. In the course of disorder, patients hold irrational fears of becoming overweight and are committed to lose weight with/without engaging bulimic behaviors. The effectiveness of drug treatment and psychotherapy is scant. Therefore, in this paper, treatment process of a 28 y.o patient with anorexia nervosa whom hospitalized to inpatient unit with 33kg is presented to discuss the effectiveness CBT treatment. After two weeks of intense psychiatric care, 10 sessions of CBT is delivered in inpatient unit resulting with significant improvements in her weight control behavior. She completed 6-week inpatient treatment and followed by this, she completed her treatment process as an outpatient client. By the end of treatment, she reached 50kg and sustained her weight afterwards. The records revealed that she manages to cope with her fears of gaining weights and stopped using safety behaviors. Moreover, it is reported that her maintaining behaviors like excessive exercising habits, purging and restrictive dieting abated. Exposure intervention is combined with CBT treatment introduced to help her to first accommodate an imaginary acceptance to idea of gaining weight and tolerating to reach her healthy targeted weight. This followed by using exposure interventions as a preventative instrument to help her overcome her fears of gaining weights, during the 6 months followup she maintained the healthy weight.

Ideal body weight for maximum life expectancy increases with advancing age. Older people, however, tend to weigh less than younger adults, and old age is also associated with a tendency to lose weight. Weight loss in older people is associated with adverse outcomes, particularly if unintentional, and initial body weight is low. When older people lose weight, more of the tissue lost is lean tissue (mainly skeletal muscle) than in younger people. When excessive, the loss of lean muscle tissue results in sarcopenia, which is associated with poor health outcomes. Unintentional weight loss in older people may be a result of protein-energy malnutrition, cachexia, the physiological anorexia of aging, or a combination of these. The physiological anorexia of aging is a decrease in appetite and energy intake that occurs even in healthy people and is possibly caused by changes in the digestive tract, gastrointestinal hormone concentrations and activity, neurotransmitters, and cytokines. A greater understanding of this decrease in appetite and energy intake during aging, and the responsible mechanisms, may aid the search for ways to treat undernutrition and weight loss in older people.

Choking phobia has been rarely described in the literature and its prevalence has not yet been determined. Because of its clinical picture (female predominance, avoidance or refusal of certain foodstuffs, secondary weight loss, associated obsessive-compulsive symptoms), it is often misdiagnosed as anorexia nervosa. The authors describe the case of an 11-year-old girl, hospitalised for anorexia, who actually had choking phobia. Following a long history of anxiety disorders (including separation anxiety, social phobia, obsessive-compulsive disorder), the choking phobia had been triggered by a traumatic choking episode occurred in her grandfather. The disorder was successfully treated by cognitive-behavioural techniques associated with an antidepressant therapy. This typical case questions the relationships between choking phobia and the other anxiety disorders of childhood and adolescence. According to data from the literature, the authors conclude that choking phobia may be regarded as a non developmental specific phobia, whose occurrence is facilitated by the presence of pre-existing anxiety disorders. The disorder is usually improved by cognitive-behavioural treatment.

Full Text Available Lindsay P Bodell, Pamela K KeelDepartment of Psychology, Florida State University, Tallahassee, FL, USAAbstract: Anorexia nervosa (AN is a serious psychiatric illness associated with significant medical and psychiatric morbidity, psychosocial impairment, increased risk of death, and chronicity. Given the severity of the disorder, the establishment of safe and effective treatments is necessary. Several treatments have been tried in AN, but few favorable results have emerged. This paper reviews randomized controlled trials in AN, and provides a synthesis of existing data regarding the efficacy, safety, and adherence associated with pharmacologic and psychological interventions. Randomized controlled trials for the treatment of AN published in peer-reviewed journals were identified by electronic and manual searches. Overall, pharmacotherapy has limited benefits in the treatment of AN, with some promising preliminary findings associated with olanzapine, an antipsychotic agent. No single psychological intervention has demonstrated clear superiority in treating adults with AN. In adolescents with AN, the evidence base is strongest for the use of family therapy over alternative individual psychotherapies. Results highlight challenges in both treating individuals with AN and in studying the effects of those treatments, and further emphasize the importance of continued efforts to develop novel interventions. Treatment trials currently underway and areas for future research are discussed.Keywords: anorexia nervosa, treatment, pharmacotherapy, psychotherapy, randomized controlled trials

The significance of socio-emotional factors in development and maintenance of Anorexia Nervosa (AN) has been noted, but the literature is poorly integrated without clear models guiding research or treatment. This systematic review retrieved experimental studies of social-cognitive or affective processing in AN and categorised them using Ochsner's "Social-Emotional Processing Stream." Ochsner's "Processing Stream", based on healthy data, comprises five constructs: (1) acquisition of and (2) recognition and response to social-affective stimuli, (3) low-level and (4) high-level mental state inference and (5) context-sensitive emotion regulation. Thirty-seven experimental studies in Anorexia Nervosa were identified, mapping on to four of the five constructs (not Construct 3). A meta-analysis of nine affect recognition studies was conducted. AN patients demonstrated impairments in each of the four domains with preliminary reports that some difficulties are trait-like, and others ameliorate following recovery. Socio-emotional data was integrated with previous reports of neural abnormalities to generate an AN specific model of socio-emotional processing. Additional research is required for further definition and to translate experimental findings into clinical practice. Copyright © 2010 Elsevier Ltd. All rights reserved.

Many models have been proposed over the years to explain how motivated feeding behavior is controlled. One of the most compelling is based on the original concepts of Eliot Stellar whereby sets of interosensory and exterosensory inputs converge on a hypothalamic control network that can either stimulate or inhibit feeding. These inputs arise from information originating in the blood, the viscera, and the telencephalon. In this manner the relative strengths of the hypothalamic stimulatory and inhibitory networks at a particular time dictates how an animal feeds. Anorexia occurs when the balance within the networks consistently favors the restraint of feeding. This article discusses experimental evidence supporting a model whereby the increases in plasma osmolality that result from drinking hypertonic saline activate pathways projecting to neurons in the paraventricular nucleus of the hypothalamus (PVH) and lateral hypothalamic area (LHA). These neurons constitute the hypothalamic controller for ingestive behavior, and receive a set of afferent inputs from regions of the brain that process sensory information that is critical for different aspects of feeding. Important sets of inputs arise in the arcuate nucleus, the hindbrain, and in the telencephalon. Anorexia is generated in dehydrated animals by way of osmosensitive projections to the behavior control neurons in the PVH and LHA, rather than by actions on their afferent inputs. PMID:17531275

This study aimed to compare a sample of females with anorexia nervosa in Singapore with international clinical and population samples from published data in terms of endorsement of risk factors related to anorexia nervosa, severity of eating pathology and levels of psychosocial impairment and to explore the nature of the relationships between the anorexia nervosa risk factors and adherence to Asian cultural values. Data from the Eating Disorder Inventory-3 (EDI-3), the Eating Attitudes Test (EAT-26), the Perceived Sociocultural Pressure Scale (PSPS), the Ideal Body Stereotype Scale (IBSS), the Eating Disorder Examination Questionnaire (EDE-Q), the Clinical Impairment Assessment Questionnaire, and the Asian American Values Scale-Multidimensional (AAVS-M) were collected from 41 female patients (13-31 years old) who presented for treatment of anorexia nervosa at the Singapore General Hospital. The profile and presentation of anorexia nervosa in Singapore was comparable to that observed in the Western clinical samples in terms of levels of endorsement of the risk factors for anorexia nervosa. No protective benefit of orientation to Asian culture was found. The observed pattern of general similarity of presentation between Western data and Singaporean data, together with the finding that no protective benefit of orientation to Asian culture was observed, suggests that it may be appropriate to directly apply evidence-based Western models of intervention to the treatment of anorexia nervosa in Singapore.
Full Text Available Animal studies are very useful in detection of early disease indicators and in unravelling the pathophysiological processes underlying core psychiatric disorder phenotypes. Early indicators are critical for preventive and efficient treatment of progressive psychiatric disorders like anorexia nervosa. Comparable to physical hyperactivity observed in anorexia nervosa patients, in the activity-based anorexia rodent model, mice and rats express paradoxical high voluntary wheel running activity levels when food restricted. Eleven inbred mouse strains and outbred Wistar WU rats were exposed to the activity-based anorexia model in search of identifying susceptibility predictors. Body weight, food intake and wheel running activity levels of each individual mouse and rat were measured. Mouse strains and rats with high wheel running activity levels during food restriction exhibited accelerated body weight loss. Linear mixed models for repeated measures analysis showed that baseline wheel running activity levels preceding the scheduled food restriction phase strongly predicted activity-based anorexia susceptibility (mice: Beta = -0.0158 (±0.003 SE, P<0.0001; rats: Beta = -0.0242 (±0.004 SE, P<0.0001 compared to other baseline parameters. These results suggest that physical activity levels play an important role in activity-based anorexia susceptibility in different rodent species with genetically diverse background. These findings support previous retrospective studies on physical activity levels in anorexia nervosa patients and indicate that pre-morbid physical activity levels could reflect an early indicator for disease severity.

Pathological concern regarding one's weight and weight gain is a crucial feature of anorexia nervosa. Consequently, anorexia nervosa patients often claim that they are uncertain regarding the amount of food they should eat. The present study investigated whether individuals with anorexia nervosa show an altered estimation of meal portion sizes and whether this estimation is modulated by an intent-to-eat instruction (where patients are asked to imagine having to eat the presented meal), meal type and meal portion size. Twenty-four women with anorexia nervosa and 27 healthy women estimated, using a visual analogue scale, the size of six different portions of three different meals, with and without intent-to-eat instructions. Subjects with anorexia nervosa estimated the size of small and medium meal portions (but not large meal servings) as being significantly larger, compared to estimates of healthy controls. The overestimation of small meal portions by anorexia nervosa subjects was significantly greater in the intent-to-eat, compared to general, condition. These findings suggest that disturbed perceptions associated with anorexia nervosa not only include interoceptive awareness (i.e., body weight and shape), but also extend to external disorder-related objects such as meal portion size. Specific therapeutic interventions, such as training regarding meal portion evaluation, could address these difficulties. Copyright © 2013. Published by Elsevier Ltd.

Introduction The amount of information being uploaded onto social video platforms, such as YouTube, Vimeo, and Veoh, continues to spiral, making it increasingly difficult to discern reliable health information from misleading content. There are thousands of YouTube videos promoting misleading information about anorexia (eg, anorexia as a healthy lifestyle). Objective The aim of this study was to investigate anorexia-related misinformation disseminated through YouTube videos. Methods We retrieved YouTube videos related to anorexia using the keywords anorexia, anorexia nervosa, proana, and thinspo on October 10, 2011.Three doctors reviewed 140 videos with approximately 11 hours of video content, classifying them as informative, pro-anorexia, or others. By informative we mean content describing the health consequences of anorexia and advice on how to recover from it; by pro-anorexia we mean videos promoting anorexia as a fashion, a source of beauty, and that share tips and methods for becoming and remaining anorexic. The 40 most-viewed videos (20 informative and 20 pro-anorexia videos) were assessed to gauge viewer behavior. Results The interrater agreement of classification was moderate (Fleiss’ kappa=0.5), with 29.3% (n=41) being rated as pro-anorexia, 55.7% (n=78) as informative, and 15.0% (n=21) as others. Pro-anorexia videos were favored 3 times more than informative videos (odds ratio [OR] 3.3, 95% CI 3.3-3.4, P<.001). Conclusions Pro-anorexia information was identified in 29.3% of anorexia-related videos. Pro-anorexia videos are less common than informative videos; however, in proportional terms, pro-anorexia content is more highly favored and rated by its viewers. Efforts should focus on raising awareness, particularly among teenagers, about the trustworthiness of online information about beauty and healthy lifestyles. Health authorities producing videos to combat anorexia should consider involving celebrities and models to reach a wider audience. More

Theory and clinical literature suggest that pride may play an important role in the maintenance of restrictive eating disorders. A grounded theory study explored experiences of, and reflections on, pride among women with a current or past diagnosis of anorexia nervosa. This is a qualitative study using grounded theory. Semistructured interviews were conducted with 21 women recruited from an eating disorder unit in England, and from a UK self-help organization. Grounded theory from a constructivist lens was used. Analysis involved coding, constant comparison, and memo-writing. Pride evolves over the course of anorexia nervosa. Two overarching conceptual categories were identified: 'pride becoming intertwined with anorexia' and 'pride during the journey towards recovery'. These categories encompassed different forms of pride: 'alluring pride', 'toxic pride', 'pathological pride', 'anorexia pride', 'shameful pride', 'recovery pride', and 'resilient pride'. Initially, pride contributed to self-enhancement and buffered negative emotions. As the condition progressed, pride became a challenge to health and interfered with motivation to change. During recovery, perceptions of pride altered as a healthy approach to living ensued. The evolving nature of pride plays a central role in development, maintenance, and treatment of anorexia nervosa. Understanding of pride and its role in psychotherapeutic work with this client group may increase motivation to change and promote recovery. Future work should investigate whether tackling pride in eating disorders increases treatment efficacy and reduces the risk of relapsing. Pride associated with anorexia appeared to evolve in nature. During early stages of the eating disorder, it stopped people from seeking help. Later on, it prevented them from seeing pride in healthy domains of life (outside anorexia). Over time, pride in anorexia became an overwhelming emotion that interfered with motivation to change. It is important for

In mental diseases, the brain does not systematically adjust motor activity to feeding. Probably, the most outlined example is the association between hyperactivity and anorexia in Anorexia nervosa. The neural underpinnings of this ‘paradox', however, are poorly elucidated. Although anorexia and hyperactivity prevail over self-preservation, both symptoms rarely exist independently, suggesting commonalities in neural pathways, most likely in the reward system. We previously discovered an addictive molecular facet of anorexia, involving production, in the nucleus accumbens (NAc), of the same transcripts stimulated in response to cocaine and amphetamine (CART) upon stimulation of the 5-HT4 receptors (5-HTR4) or MDMA (ecstasy). Here, we tested whether this pathway predisposes not only to anorexia but also to hyperactivity. Following food restriction, mice are expected to overeat. However, selecting hyperactive and addiction-related animal models, we observed that mice lacking 5-HTR1B self-imposed food restriction after deprivation and still displayed anorexia and hyperactivity after ecstasy. Decryption of the mechanisms showed a gain-of-function of 5-HTR4 in the absence of 5-HTR1B, associated with CART surplus in the NAc and not in other brain areas. NAc-5-HTR4 overexpression upregulated NAc-CART, provoked anorexia and hyperactivity. NAc-5-HTR4 knockdown or blockade reduced ecstasy-induced hyperactivity. Finally, NAc-CART knockdown suppressed hyperactivity upon stimulation of the NAc-5-HTR4. Additionally, inactivating NAc-5-HTR4 suppressed ecstasy's preference, strengthening the rewarding facet of anorexia. In conclusion, the NAc-5-HTR4/CART pathway establishes a ‘tight-junction' between anorexia and hyperactivity, suggesting the existence of a primary functional unit susceptible to limit overeating associated with resting following homeostasis rules.

The anorexia that results from extended periods of cellular dehydration is an important physiological adaptation that limits the intake of osmolytes from food and helps maintain the integrity of fluid compartments. The ability to experimentally control both the development and reversal of anorexia, together with the understanding of underlying hormonal and neuropeptidergic signals, make dehydration (DE)-anorexia a powerful model for exploring the interactions of neural networks that stimulate and inhibit food intake. However, it is not known which meal parameters are affected by cellular dehydration to generate anorexia. Here we use continuous and high temporal resolution recording of food and fluid intake, together with a drinking-explicit method of meal pattern analysis to explore which meal parameters are modified during DE-anorexia. We find that the most important factor responsible for DE-anorexia is the failure to maintain feeding behavior once a meal has started, rather than the ability to initiate a meal, which remains virtually intact. This outcome is consistent with increased sensitivity to satiation signals and post-prandial satiety mechanisms. We also find that DE-anorexia significantly disrupts the temporal distribution of meals across the day so that the number of nocturnal meals gradually decreases while diurnal meal number increases. Surprisingly, once DE-anorexia is reversed this temporal redistribution is maintained for at least 4 days after normal food intake has resumed, which may allow increased daily food intake even after normal satiety mechanisms are reinstated. Therefore, DE-anorexia apparently develops from a selective targeting of those neural networks that control meal termination, whereas meal initiation mechanisms remain viable. PMID:21854794

This study aims at examining whether adolescent girls diagnosed with anorexia nervosa and their parents differ in perceiving the different aspects of family functioning. Moreover, the discrepancy between adolescent girls and healthy controls on Family Adaptability and Cohesion Evaluation Scales dimensions, family communication, and family satisfaction is investigated. The study includes 36 female anorexia patients and their parents and 36 healthy controls. The results showed a different view between mothers and their daughters with regard to the dimension of rigidity. In addition, girls with anorexia nervosa were less satisfied about family environment and rated their families as less communicative, flexible, cohesive, and more disengaged, compared to controls.

Full Text Available OBJETIVO: avaliar a ingestão diária de cálcio e estabelecer sua correlação com a densidade óssea de pacientes com anorexia nervos. PACIENTES E MÉTODOS: quatorze mulheres com anorexia nervosa registraram, em diário alimentar padronizado, sua ingestão em 24 horas e foram submetidas ao exame de densitometria óssea. A análise estatística foi feita pelos testes do c² e correlação de Pearson, adotando-se como significância estatística p<0,05. RESULTADOS: a média da densidade óssea na coluna lombar foi de 0,95 ± 0,15 e no colo do fêmur foi de 0,88 ± 0,26. Houve correlação significativa entre o tempo de amenorréia e a perda de massa óssea, tanto na coluna lombar (r=-0,65; p=0,01 como no fêmur (r=-0,71; (p=0,0068. Com exceção de uma paciente, todas apresentavam ingestão de cálcio inferior ao recomendado pelo RDA, com média de 554,5 mg/dia (variando de 120 a 840 mg/dia. Observou-se que 64% das pacientes apresentavam algum grau de perda de massa óssea (osteopenia ou osteoporose na coluna e 57% no fêmur. Das seis pacientes com déficit na ingestão de cálcio inferior a 60%, nenhuma apresentou osteoporose, ao passo que das oito pacientes com déficit superior a 60% na ingestão de cálcio, três tinham osteoporose. CONCLUSÃO: Pacientes com anorexia nervosa têm baixa ingestão de cálcio e perda significativa de massa óssea, que estão diretamente relacionadas entre si. A baixa densidade óssea está, também, correlacionada com o tempo de amenorréia.

There is increasing evidence that anorexia of aging can cause physical and mental impairment. The aim of the present study was to evaluate the relationship between anorexia and sarcopenia in elderly persons aged 80 years or older. Data are from the baseline evaluation of 354 subjects enrolled in the ilSIRENTE study. The ilSIRENTE study is a prospective cohort study performed in the mountain community living in the Sirente geographic area (L'Aquila, Abruzzo) in Central Italy. We defined anorexia as the presence of loss of appetite and/or lower food intake. According to the European Working Group on Sarcopenia in Older People (EWGSOP) criteria, diagnosis of sarcopenia required the documentation of low muscle mass plus the documentation of either low muscle strength or low physical performance. The relationship between anorexia and sarcopenia was estimated by deriving odds ratios from the multiple logistic regression models considering sarcopenia as the dependent variable. Nearly 21 % of the study sample showed symptoms of anorexia. Using the EWGSOP-suggested algorithm, 103 subjects (29.1 %) with sarcopenia were identified. Thirty-four (46.6 %) participants were affected by sarcopenia among subjects with anorexia compared to 69 subjects [24.6 %] without anorexia (p anorexia had a higher risk of sarcopenia compared with non-anorexic subjects (HR 1.88, 95 % CI 1.01-3.51). Anorexia is common among community-dwelling older subjects in Italy. Our results suggest that among old-old subjects, anorexia is independently associated with sarcopenia.

There is growing interest in the relationship between anorexia nervosa (AN) and autism spectrum disorder (ASD). This review aimed to synthesise the most recent research on this topic to identify gaps in current knowledge, directions for future research and reflect on implications for treatment. Eight studies assessing the presence of ASD in AN were identified in the literature along with three studies examining the impact of symptoms of ASD on treatment outcome. Research with young people and using parental-report measures suggest lower rates of co-morbidity than previous adult studies. The wide range of diagnostic tools, methodologies and populations studied make it difficult to determine the prevalence of ASD in AN. Despite this, studies consistently report over-representation of symptoms of ASD in AN. Co-morbid AN and ASD may require more intensive treatment or specifically tailored interventions. Future longitudinal research and female-specific diagnostic tools would help elucidate the relationship between these two disorders.

The research aimed to identify the interaction of nurses and clients suffering from bulimia and anorexia. We use the case study as a resource in which we collect clinical data and did interviews with eight of fourteen nurses, who have been our subject-object. According to the nurses, clients are isolated from the world living in a world without hunger and mirrors reflecting a body always above the "ideal weight", they were lonely people, personnel who have lost their shine, sending signals that could extinguish their lives at any time. In the study, was possible to identify the manner in which nurses interacted and perceived customers and, as a result, we elucidate a peculiar practice in nursing.

Individuals with anorexia nervosa (AN) experience insecure attachment. We investigated whether insecure attachment is associated with punishment and reward sensitivity in women with AN. Women with AN (n = 24) and comparison women (n = 26) (CW) completed The Eating Disorder Examination Questionnaire, Depression Anxiety Stress Scale, The Attachment Style Questionnaire, and Sensitivity to Punishment/Sensitivity to Reward Questionnaire. Participants with AN returned higher ratings for insecure attachment (anxious and avoidant) experiences and greater sensitivity to punishment (p = 0.001) than CW. In AN, sensitivity to punishment was positively correlated with anxious attachment and negative emotionality but not eating disorder symptoms. Regression analysis revealed that anxious attachment independently predicted punishment sensitivity in AN. Anxious attachment experiences are related to punishment sensitivity in AN, independent of negative emotionality and eating disorder symptoms. Results support ongoing investigation of the contribution of attachment experiences in treatment and recovery.

Full Text Available Anorexia nervosa (AN is considered a relatively “modern” disorder; however, a number of scholarly works have cited examples of voluntary self-starvation dating back to several centuries. In particular, there are many examples of female starvation for religious reasons during the medieval period, with many being elevated to sainthood. We present a case of an elderly woman with AN who began restricting her diet when she was 13-years old while studying to be a nun at a Catholic convent. She reports that, during the development of her disease, she had no mirrors and, rather than restricting her diet to be thin or attractive, she restricted her diet to be closer to God in hopes of becoming a Saint. This unique case presents an opportunity to deepen our understanding of AN and the cultural context that affects its development.

To test whether intolerance of uncertainty (IU) is related to eating disorder (ED) pathology. Thirty individuals with anorexia nervosa (AN), 19 with bulimia nervosa (BN), and 28 healthy control women (CW) completed the Intolerance of Uncertainty Scale (IUS). AN and BN groups showed higher IU compared with CW. In AN and BN, Harm Avoidance and Depression scores were positively correlated with IU. In AN but not BN, IU was related positively to Drive for Thinness and Body Dissatisfaction. Elevated IU is associated with AN and BN. Anxious traits may be inherent in EDs and IU could be a developmental factor contributing to anxiety, mood, and ED behavior in AN and BN. Copyright © 2011 Wiley Periodicals, Inc.
Full Text Available A 21-year-old girl presented with acute painless vision loss in her right eye. There was no remarkable ocular history and she had a history of anorexia nervosa. At presentation best-corrected visual acuities were counting fingers from 2 meters and 20/20, in the right and left eyes, respectively. Slit lamp examination result was normal. Fundus examination revealed multiple cotton wool spots and intraretinal hemorrhages surrounding the optic disc and macula in the right eye. Fluorescein angiography showed capillary filling defect and leakage from optic disc in the late phase of the angiogram. One week later best-corrected visual acuities remained the same in both eyes with similar fundus appearance. One month after initial presentation visual acuity was 20/20 in both eyes with no abnormality in fundus appearance.

An emotion-focused approach to the treatment of eating disorders and to case formulation is described in an individual with anorexia nervosa (AN). The basic theory of emotion-focused therapy (EFT), the steps of case formulation and an outline of the tasks and course of treatment of an individual recently hospitalized on an inpatient unit for eating disorders highlight key aspects of the approach. The transformation in this individual, in terms of gaining access to her internal experience, understanding and tolerating her emotions, and working through her core themes of insecure attachment and worthlessness, is described. Weight and scores on self-report measures at the outset of treatment and at 18 months are provided.

Activation of the immune system is metabolically costly, yet a hallmark of an infection is a reduction in appetite with a subsequent reduction in metabolite provision. What is the functional value of decreasing nutrient intake when an infection imposes large demands on metabolic parameters? Here, we propose that sickness-associated anorexia (SAA) upregulates the ancient process of autophagy systemically, thereby profoundly controlling not only immune- but also nonimmune-competent cells. This allows an advanced impact on the resolution of an infection through direct pathogen killing, enhancement of epitope presentation and the contribution toward the clearance of noxious factors. By rendering a 'free meal,' autophagy is thus most fundamentally harnessed during an anorexic response in order to promote both host tolerance and resistance. These findings strongly suggest a reassessment of numerous SAA-related clinical applications and a re-evaluation of current efforts in patient care.

Contemporary understandings of anorexia nervosa are framed by the body image paradigm. The body-image framework considers that women's bodily experiences are reflected through distorted mental images of their bodies or disordered thinking and behavior around food and eating. Body image has come to symbolize all that can go wrong with women's relationship with their bodies, food and eating. The problem with this approach is its failure to consider the experience of women who survived childhood abuse. Women's bodily disturbances are not easily discernible through objective measures as they lie within the inner subjective realm of the embodied 'self', and embodied emotional experience. Consideration of the different ways that women inhabit their bodies inform this paper's examination of the conceptual framework embodiment as an alternate to the body image paradigm.

Anorexia nervosa (AN) is characterized by severe undernutrition associated with alterations in multiple endocrine axes, which are primarily adaptive to the state of caloric deprivation. Hormonal changes include growth hormone (GH) resistance with low insulin like growth factor-1 (IGF-1) levels, hypothalamic hypogonadism, relative hypercortisolemia and changes in appetite regulating hormones, including leptin, ghrelin, and peptide YY. These alterations contribute to abnormalities in bone metabolism leading to low bone mass, impaired bone microarchitecture, and increased risk for fracture, and may also negatively impact cognition, emotions and mood. The best strategy to improve all biologic outcomes is weight and menstrual recovery. Physiological estrogen replacement improves bone accrual rates and measures of trait anxiety in adolescents with AN. Other therapies including testosterone and IGF-1 replacement, and use of DHEA with oral estrogen-progesterone combination pills, bisphosphonates and teriparatide have also been studied to improve bone outcomes.

Frequently, depression is a concomitant pathology in anorexia nervosa. To verify this, we carried out a comparative case/control study with 50 anorexic patients, restricting-type (ANP), 50 depressed patients (DP) and 50 non-patients (NP), aged between 13 and 16. We used the Rorschach Test and the Minnesota Multiphasic Personality Inventory (MMPI) and compared the results to parent's observations collected from the Achenbach Child Behavior Checklist (CBCL). Results showed two clearly different groups among participants: ANP with depression (36%) and ANP without depression (64%). This seems to indicate that depression is not a core element in anorexic disorders. However, we also observed a significant increase in the MMPI scale 2, which was probably related to starvation and weight loss. We confirmed the absence of general anxiety in the ANP group and obtained differences between depressive symptoms and those derived from coping deficit disorders. The discussion emphasizes the importance of using several tests to reduce bias in results and conclusions.

Cognitive behavioral therapy (CBT) for anorexia nervosa (AN), based on Beck's cognitive theory, was developed in a "generic" form in the early eighties. In recent years, however, improved knowledge of the mechanisms involved in maintaining eating disorder psychopathology has led to the development of a "specific" form of CBT, termed CBT-E (E = enhanced), designed to treat all forms of eating disorders, including AN, from outpatient to inpatient settings. Although more studies are required to assess the relative effectiveness of CBT-E with respect to other available treatments, the data indicate that in outpatient settings it is both viable and promising for adults and adolescents with AN. Encouraging results are also emerging from inpatient CBT-E, particularly in adolescents, and clinical services offering CBT-E at different levels of care are now offered in several countries around the world. However, CBT-E requires dissemination in order to become widely available to patients.

Recent research has modified both the conceptualization and treatment of eating disorders. New diagnostic criteria reducing the "not otherwise specified" category should facilitate the early recognition and treatment of anorexia nervosa (AN) and bulimia nervosa (BN). Technology-based studies identify AN and BN as "brain circuit" disorders; epidemiologic studies reveal that the narrow racial, ethnic and income profile of individuals no longer holds true for AN. The major organs affected long term-the brain and skeletal system-both respond to improved nutrition, with maintenance of body weight the best predictor of recovery. Twin studies have revealed gene x environment interactions, including both the external (social) and internal (pubertal) environments of boys and of girls. Family-based treatment has the best evidence base for effectiveness for younger patients. Medication plays a limited role in AN, but a major role in BN. Across diagnoses, the most important medicine is food.

A systematic literature review published between 1990 and 2006 using a qualitative approach was conducted to explore family members' perception of anorexia and bulimia nervosa patients. Articles were critically reviewed and a meta-synthesis analysis was carried out based on a meta-ethnographic method to analyze and summarize data. Of a total of 3,415 studies, nine met the study inclusion and exclusion criteria. Reciprocal translation was used for data interpretation allowing to identifying two concepts: disease awareness and disease impacts. Feelings of impotence were often described in family reorganization. The study results point to distortions in the concept of disease associated with family involvement, resulting in changes in communication, attitudes, and behaviors in a context of impotence.

1 Anorexia in rats following injections of mazindol (0.1-8 mg/kg i.p.) could be antagonized by pretreatment with a dopamine receptor blocker (primozide) but not by pretreatment with an alpha-adrenoceptor blocker (phenoxybenzamine), a beta-adrenoceptor blocker ((-)-propranolol), or a 5-hydroxytryptamine receptor blocker (methergoline). 2 In rats with a unilateral lesion in the substantia nigra made by stereotaxic injection of 6-hydroxydopamine, mazindol caused a dose-dependent turning towards the lesioned side, indicating an indirect mechanism of action. This effect could be antagonized by pretreatment with a dopamine receptor blocker. 3 In rats pretreated with reserpine and alpha-methyl-p-tyrosine, mazindol did not have any motor stimulant action. 4 In vitro studies with synaptosomes prepared from rat brain, indicated that mazindol blocks uptake and causes release of dopamine. 5 It is concluded that the anorectic action of mazindol is mediated by a dopaminergic mechanism.

Little has been published about the co-occurrence of gender dysphoria (GD) and eating disorders (ED) in adults, with no cases described in the adolescent population. The emphasis on body shape in both conditions suggests that there may be some overlap in symptomatology. We report two adolescent cases initially diagnosed with anorexia nervosa who later met criteria for GD. The drive for thinness for the 16-year-old male was associated with a wish to achieve a feminine physique whereas there was an emphasis for stunted breast growth and a desire for muscularity in the 13-year-old female. Complexities in presentation, evolution of symptoms over time, and the treatment of the two cases are discussed. Clinicians should inquire about sexual issues in the presentation of ED and should monitor for symptoms of GD, not only at initial presentation, but throughout treatment, especially as weight gain progresses. © 2014 Wiley Periodicals, Inc.

Full Text Available This is a case story of a 14-year-old girl with severe anorexia nervosa (AN (158 cm, 28 kg, –44.1% ideal body mass index, admitted with purpura, edema, and general fatigue. We treated her carefully and paid particular attention to prevent development of refeeding syndrome (RS, and her body weight increased satisfactorily. However, RS (edema, hypoalbuminemia, and heart failure occurred despite careful treatment. We used albumin and diuretics for treatment of RS, but severe liver damage resulted. RS was aggravated by the medical treatment. More attention should have been paid to her weight gain and medical treatment should have been initiated more slowly to prevent dramatic changes in the patient's fluid and electrolyte status.

Low triiodothyronine syndrome is a physiological adaptation encountered in anorexia nervosa (AN) and generally improves with sufficient weight gain. However, when a primary thyroid pathology accompanies AN, both the evaluation of thyroid hormone levels and the management of the co-morbid disease become more challenging. Hashimoto thyroiditis could complicate the management of AN by causing hyper- or hypothyroidism. AN could also negatively affect the treatment of Hashimoto thyroiditis by altering body weight and metabolic rate, as well as by causing drug non-compliance. We present the case of a 15-year-old boy with comorbid AN restrictive sub-type and Hashimoto thyroiditis. In this case report, we aimed to draw attention to the challenges that could be encountered in the diagnosis, treatment, and follow-up of patients with AN when accompanied by Hashimoto thyroiditis.

Objective To test whether intolerance of uncertainty (IU) is related to eating disorder (ED) pathology. Method Thirty individuals with anorexia nervosa (AN), 19 with bulimia nervosa (BN) and 28 healthy control women (CW) completed the Intolerance of Uncertainty Scale (IUS). Results AN and BN groups showed higher IU compared to CW. In AN and BN, Harm Avoidance and Depression scores were positively correlated with IU. In AN but not BN, IU was related positively to Drive for Thinness and Body Dissatisfaction. Conclusion Elevated IU is associated with AN and BN. Anxious traits may be inherent in EDs and IU could be a developmental factor contributing to anxiety, mood and ED behavior in AN and BN. PMID:21495057

Full Text Available Investigação que objetivou identificar a interação de enfermeiros e clientes portadores de bulimia e anorexia. Utilizamos o estudo de caso como recurso, para o qual coletamos dados de prontuários e fizemos entrevistas com oito de quatorze enfermeiros, que foram nossos sujeitos-objeto. De acordo com os enfermeiros, os clientes se isolavam do mundo, vivendo num mundo sem fome e de espelhos que refletiam um corpo sempre acima do "peso ideal"; eram pessoas solitárias, que perderam o brilho pessoal, emitindo sinais de que podiam extinguir a vida deles a qualquer momento. Com o estudo, foi possível identificar a maneira pela qual os enfermeiros interagiam e percebiam os clientes e, em decorrência disso, explicitamos uma prática de cuidar peculiar na enfermagem.
Full Text Available Abstract Anorexia nervosa is a clinically significant illness that may be associated with permanent medical complications involving almost every organ system. The paper raises a question whether some of them are associated with premorbid vulnerability such as subcellular ion channel abnormalities ('channelopathy' that determines the clinical expression of the bodily response to self-imposed malnutrition. Aberrant channels emerge as a tempting, if rather speculative alternative to the notion of cognitively-driven neurotransmitter modulation deficit in anorexia nervosa. The concept of channelopathies is in keeping with some characteristics of anorexia nervosa, such as a genetically-based predisposition to hypophagia, early onset, cardiac abnormalities, an appetite-enhancing efficacy of some antiepileptic drugs, and others. The purpose of this article is to stimulate further basic research of ion channel biophysics in relation to restrictive anorexia.
Clinical studies describe binge eating as a reaction to hunger, negative affect, or the need to dissociate. However, little is known about the meanings that women with bulimia nervosa and anorexia nervosa associate with binge eating. To examine how women with anorexia nervosa and bulimia nervosa interpret their experiences of binge eating. Sixteen women who engaged in binge eating and had been diagnosed with anorexia nervosa, bulimia nervosa, or their subclinical variants were interviewed about their experiences of eating disorder. Interview data were analyzed using phenomenologically-informed thematic analysis. Participants described binge eating as a practice through which the self experiences a sense of release, and existential emptiness is replaced by overwhelming fullness. Meaningful experiences of release and fullness are central to binge eating in bulimia nervosa and anorexia nervosa, and may contribute to the long-term maintenance of this practice.
Anorexia nervosa as a psychiatric disorder presents itself through the concreteness of symptoms. Emotions are experienced as a corporeality here-and-now. In a companion article, Part I, different 'body metaphors' are described and categorised. The human body functions as metaphor, and in anorexia nervosa there is a striking closeness between emotions and different bodily experiences. This is interpreted as impaired 'reflective function', referring to the capacity to make mental representations, and is proposed as a central psychopathological feature. The psychodynamic concepts 'concretised metaphors' and 'psychic equivalence' are discussed as useful tools to better understand such compromised symbolic capacity. Psychotherapy in anorexia nervosa can be described as a relational process where concretised metaphors will be developed into genuine linguistic ones. Part III in this series of articles presents an outline for psychotherapy for anorexia nervosa. 2007 John Wiley & Sons, Ltd and Eating Disorders Association

Anorexia nervosa (AN) inevitably begins with dieting. Yet, it is unknown whether anyone who will ultimately suffer from anorexia is already ill upon "going on a diet", or whether disease begins during, and is perhaps triggered by, dieting. The objective of the following study was to precipitate anorexia by imposing diet restriction on animals, as a model for generating AN in humans. Three hundred young female Sabra mice were diet restricted to 40% of daily nutrient requirements for 12 days, lost 17% of body weight and were then re-fed ad-lib. All mice regained appetite and weight. Our conclusions are that diet restriction does not precipitate anorexia in mice. Our findings do not support a role for diet restriction per se in triggering AN.

Anorexia is a common manifestation of chronic diseases, including cancer. Here we investigate the contribution to cancer anorexia made by calcitonin gene-related peptide (CGRP) neurons in the parabrachial nucleus (PBN) that transmit anorexic signals. We show that CGRP PBN neurons are activated in mice implanted with Lewis lung carcinoma cells. Inactivation of CGRP PBN neurons before tumor implantation prevents anorexia and loss of lean mass, and their inhibition after symptom onset reverses anorexia. CGRP PBN neurons are also activated in Apc min/+ mice, which develop intestinal cancer and lose weight despite the absence of reduced food intake. Inactivation of CGRP PBN neurons in Apc min/+ mice permits hyperphagia that counteracts weight loss, revealing a role for these neurons in a 'nonanorexic' cancer model. We also demonstrate that inactivation of CGRP PBN neurons prevents lethargy, anxiety and malaise associated with cancer. These findings establish CGRP PBN neurons as key mediators of cancer-induced appetite suppression and associated behavioral changes.

The cross-sectional study aimed at examining the sexual function of young adult women suffering from eating disorders. The authors interviewed 53 women (26 with anorexia nervosa and 27 with bulimia nervosa) and 58 female students. Each participant was administered the Female Sexual Function Index, the Eating Attitudes Test, the Body Shape Questionnaire, and the Beck Depression Inventory. Comparisons among the 3 groups showed that patients with anorexia nervosa scored lower in each Female Sexual Function Index subscale than did healthy controls. There was no significant difference between bulimia nervosa and healthy controls. Sexual functionality of patients with anorexia nervosa was correlated only with body mass index (r = 0.5, p =.01). Sexual functionality of patients with bulimia nervosa was correlated only with the Beck Depression Inventory (r = -0.4, p =.03) Patients with anorexia nervosa had more disturbed sexual function than did controls. Sexual function can be related to the level of starvation and symptoms of depression.

, however, this has been reported to be absent in normal weighted amenorrheic athletes. Anorexia nervosa is associated with multiple endocrine abnormalities. Hypothalamic amenorrhoea often precedes the weight loss and may persist after weight recovery. We hypothesized that leptin could be involved...... in the regulation of eating behaviour and gonadal function in anorexia nervosa. DESIGN: We measured the concentration of leptin in serum samples taken after an overnight fast in 18 female anorexia nervosa patients and 11 controls. To study diurnal variation, eight patients and 11 controls were hospitalized for 24 h...... and had a standardized diet at regular times. Seven blood samples were obtained at 4 h intervals from each subject. PATIENTS: The patients fulfilled the DSM-IV criteria for anorexia nervosa. The mean body mass index for the patients was 14.2 +/- 2.3 kg/m2 and for controls 20.3 +/- 1.7 kg/m2. RESULTS...
Full Text Available The prevalence of eating disorders is on the increase in adolescence and childhood. The peak age of onset occurs between 14 and 19 years. Anorexia nervosa is diagnosed approximately nine times more often in females than in males. Anorexia nervosa is a eating disorder that occurs mainly in female adolescents and young women. Eating disorders are associated with severe and sometimes life-threatening medical and psychiatric comorbidities. Hematological abnormalities are common in anorexia nervosa. But severe bone marrow supression has rarely been reported. To our knowledge, there is not any publication in the literature about bone marrow supression due to constipation.We reported here a 17 years old girl diagnosed as anorexia nervosa who was not wasted yet, presented with constipation and developed fever and pancytopenia.

The coexistence of Type 1 Diabetes Mellitus and anorexia nervosa results in an increased incidence of known diabetic complications such as retinopathy and nephropathy, presumably because blood glucose is difficult to control within the throes of comorbid anorexia nervosa. In addition, even when a diabetic patient with anorexia nervosa has committed to resolving his or her eating disorder, glucose control is again difficult and fraught with complexity and peril as will be highlighted in the following case report. Prudence dictates that strict glucose control is not indicated for the relatively short period of time that constitutes the early stage of refeeding in a patient with severe anorexia nervosa. Rather, "permissive hyperglycemia" may be the more optimal course to pursue, as a clinical strategy which is considerate of both the criticality of the refeeding treatment plan and of the long-term nature of the diabetic illness. © 2014 Wiley Periodicals, Inc.

Anorexia nervosa (AN) is a serious disorder with associated morbidity and mortality, most commonly diagnosed in females. Existing literature on male anorexia is sparse, and a review of the endocrine effects of AN in males has not previously been published. Our objective is to highlight the clinical characteristics of AN in males as a routinely overlooked cause of multiple endocrinopathies and systemic illness in hospitalized patients. We present 4 cases (2 cases at The Mount Sinai Hospital; 2 cases at Long Island Jewish Hospital) of young men with hormonal dysfunction due to underlying AN. Pertinent de-identified data were collected from a chart review of cases seen on the endocrinology consult service at both hospitals. Institutional Review Board approval was not required for an observational report of the cases presented. Four young men with AN demonstrated evidence of multiple systemic complications from severe caloric and protein malnutrition. Varying degrees of endocrinopathies were present, including hypogonadotropic hypogonadism, hypercortisolemia, and nonthyroidal illness syndrome, resulting in bradycardia, gastroparesis, hypothermia, acute systolic heart failure, and erectile dysfunction. Ages at diagnosis were 20, 24, 23, and 20 years, with mean age 21.75 years. Most of the clinical effects from these endocrinopathies resolved with improved caloric intake and nutrition, although symptoms of hypogonadism persisted. This small case series highlights the importance of AN as a potential cause of multiple endocrinopathies in males. The heterogeneous presentations and varying degrees of clinical manifestations in our cohort emphasize the challenge in diagnosis. Increased awareness of AN in males is vital, as its prevalence is likely underestimated and appropriate diagnosis and treatment can ameliorate the metabolic dysfunction in a majority of cases. Further studies on males with eating disorders are needed to help guide diagnostic and therapeutic decisions.

Obesity and eating disorders are prevailing health concerns worldwide. It is important to understand the regulation of food intake and energy metabolism. Thiamine (vitamin B1) is an essential nutrient. Thiamine deficiency (TD) can cause a number of disorders in humans, such as Beriberi and Wernicke-Korsakoff syndrome. We demonstrated here that TD caused anorexia in C57BL/6 mice. After feeding a TD diet for 16days, the mice displayed a significant decrease in food intake and an increase in resting energy expenditure (REE), which resulted in a severe weight loss. At the 22nd day, the food intake was reduced by 69% and 74% for male and female mice, respectively in TD group. The REE increased by ninefolds in TD group. The loss of body weight (17-24%) was similar between male and female animals and mainly resulted from the reduction of fat mass (49% decrease). Re-supplementation of thiamine (benfotiamine) restored animal's appetite, leading to a total recovery of body weight. The hypothalamic adenosine monophosphate-activated protein kinase (AMPK) is a critical regulator of food intake. TD inhibited the phosphorylation of AMPK in the arcuate nucleus (ARN) and paraventricular nucleus (PVN) of the hypothalamus without affecting its expression. TD-induced inhibition of AMPK phosphorylation was reversed once thiamine was re-supplemented. In contrast, TD increased AMPK phosphorylation in the skeletal muscle and upregulated the uncoupling protein (UCP)-1 in brown adipose tissues which was consistent with increased basal energy expenditure. Re-administration of thiamine stabilized AMPK phosphorylation in the skeletal muscle as well as energy expenditure. Taken together, TD may induce anorexia by inhibiting hypothalamic AMPK activity. With a simultaneous increase in energy expenditure, TD caused an overall body weight loss. The results suggest that the status of thiamine levels in the body may affect food intake and body weight.

Atypical anorexia nervosa (AAN) is defined by the symptoms of anorexia nervosa in the presence of "significant weight loss" in individuals who are not underweight. Description of current weight in AAN has been limited, significant weight loss has not been defined, and the distinction between having AAN versus having weight suppression has not been examined. Secondary analyses were conducted with data from an epidemiological study of women (n = 1,640) and men (n = 794). Three definitions of significant weight loss (5, 10, and 15%) for AAN were tested in comparisons with controls and a DSM-5 eating disorder group (DSM-5 ED) on measures of eating pathology and clinical significance using ANCOVA and logistic regression, controlling for age and body mass index. Secondary analyses compared AAN to a weight suppressed group (WS-only) and a cognitive concerns group (COG-only). Across weight loss thresholds, ≥25% of adults with AAN were currently overweight/obese. At the 5% and 10% definitions, AAN was associated with elevated eating pathology and distress relative to controls, WS-only, and COG-only in women and men. Women with AAN endorsed less eating pathology and distress than DSM-5 ED at some weight loss definitions, whereas men with AAN did not differ from DSM-5 ED in eating pathology or distress. Results support that even a 5% weight loss, combined with cognitive concerns, may produce a group with a clinically significant eating disorder. AAN was observed in both healthy weight and overweight/obese adults, highlighting the importance of screening for restrictive eating disorders at all weights. © 2017 Wiley Periodicals, Inc.

Since estradiol exercises inhibitory effect on food intake, we wanted to find out if this influence of estradiol is mediated by cocaine- and amphetamine-regulated transcript peptide (CART), a well established anorectic agent in the brain. Ovariectomized (OVX) rats, replaced with estradiol to produce estrous-phase like conditions, showed a significant decrease in food intake as compared with that in OVX controls. Intracerebroventricular (icv) administration of CART (0.5-1 μg/rat) to OVX rats, resulted in a dose-dependent reduction in the food intake. The lower dose (0.25 μg) had no effect, and was considered subeffective. In estradiol replaced OVX rats, CART at subeffective dose, further reduced food intake. However, CART failed to reduce food intake in estradiol replaced OVX rats pretreated with anti-estrogenic agent tamoxifen (3 mg/kg, subcutaneous). Administration of CART antibody (1:500 dilution/rat, i.c.v.) significantly attenuated estradiol-induced anorexia in the OVX rats. While estradiol replacement significantly increased CART-immunoreactivity in the cells/fibers of paraventricular nucleus (PVN) of OVX rats, fibers in the anteroventral periventricular nucleus (AVPV), and cells/fibers in the arcuate nucleus (ARC) showed considerable reduction. These changes were attenuated following concurrent injection of tamoxifen to the estradiol replaced OVX rats. However, CART-immunoreactive cells/fibers in the periventricular area did not respond to any of the treatments. We suggest that estradiol treatment might influence the hypothalamic CART system in a site specific manner. While increased CART activity in the PVN might produce anorexia, reduction of CART in ARC and AVPV might represent a compensatory homeostatic response. Copyright © 2011 Elsevier Inc.

Background Anorexia nervosa is a serious illness with a high mortality rate, a poor outcome, and no empirically supported treatment of choice for adults. Patients with anorexia nervosa strive for thinness in order to obtain self-control and are ambivalent toward change and toward treatment. In order to achieve a greater understanding of patients’ own understanding of their situation, the aim of this study was to examine the expectations of potential anorexic patients seeking treatment at a specialized eating-disorder unit. Methods A qualitative study design was used. It comprised 15 women between 18 and 25 years of age waiting to be assessed before treatment. The initial question was, “What do you expect, now that you are on the waiting list for a specialized eating-disorder unit?” A content analysis was used, and the text was coded, categorized according to its content, and further interpreted into a theme. Results From the results emerged three main categories of what participants expected: “treatment content,” “treatment professionals,” and “treatment focus.” The overall theme, “receiving adequate therapy in a collaborative therapeutic relationship and recovering,” described how the participants perceived that their expectations could be fulfilled. Discussion Patients’ expectations concerning distorted thoughts, eating behaviors, a normal, healthy life, and meeting with a professional with knowledge and experience of eating disorders should be discussed before treatment starts. In the process of the therapeutic relationship, it is essential to continually address patients’ motivations, in order to understand their personal motives behind what drives their expectations and their desire to recover.

Although weight history is relevant in predicting eating disorder symptom severity, little is known about its role in the etiology of anorexia nervosa (AN). This study aimed to determine whether BMI or BMI trajectory differed between individuals who later developed adolescent-onset AN and a comparison group of HCs between school grades 1 through 6. This study was based on longitudinal data that identified 51 adolescents with AN and 51 matched HCs. Cases were identified through community screening in Sweden and included individuals born in 1969 through 1977. Measured weights and heights were retrieved and BMIs and weight trajectories of the AN and HC groups were compared using growth curve analysis. Main outcome measures included measured BMI and BMI trajectories from grades 1-6. Secondary outcomes examined included ponderal index at birth and maternal body weight. Individuals who later developed AN had higher BMIs than HCs between grades 1 and 6, by an average of 1.42 BMI-units. There was no difference in rate of weight gain between groups. Ponderal index at birth was higher for the AN as compared with HC group. Maternal weight did not differ significantly between groups. These findings, combined with those previously reported on the premorbid BMIs of those with bulimia nervosa, suggest that a predisposition toward elevated premorbid BMIs during childhood characterizes those who later develop anorexia or bulimia nervosa. These findings are consistent with a transdiagnostic perspective and suggest shared risk factors for AN and obesity. © 2016 Wiley Periodicals, Inc.

Background The objectives of this study were to explore associations between autistic traits and self-reported clinical symptoms in a population with anorexia nervosa (AN). Experimental and self-report evidence reveals similarities between AN and autism spectrum condition (ASC) populations in socio-emotional and cognitive domains; this includes difficulties with empathy, set-shifting and global processing. Focusing on these similarities may lead to better tailored interventions for both conditions. Methods A cross-sectional independent-groups design was employed. Participants with AN (n = 66) and typical controls (n = 66) completed self-report questionnaires including the Short (10-Item) Version Autism Spectrum Quotient (AQ-10) questionnaire (the first time this has been implemented in this population), the Eating Disorder Examination Questionnaire, the Hospital Anxiety and Depression Scale and the Work and Social Adjustment Scale. Group differences and the relationship between autistic traits and other questionnaire measures were investigated. Results The AN group had a significantly higher AQ-10 total score and a greater proportion scored above the clinical cut-off than the control group. Seven out of ten AQ-10 items significantly discriminated between groups. In the AN group, levels of autistic traits correlated with a greater self-reported anxiety and depression and a lower ability to maintain close relationships; however, eating disorder symptoms were not associated with autistic traits. Conclusions Women with anorexia possess a greater number of autistic traits than typical women. AQ-10 items that discriminated between groups related to ‘bigger picture’ (global) thinking, inflexibility of thinking and problems with social interactions, suggesting that autistic traits may exacerbate factors that maintain the eating disorder rather than cause the eating disorder directly. Using screening instruments may improve understanding of patients’ problems, leading

Background The neurobiology of anorexia nervosa is poorly understood. Neuronal networks contributing to action selection, self-regulation and interoception could contribute to pathologic eating and body perception in people with anorexia nervosa. We tested the hypothesis that the salience network (SN) and default mode network (DMN) would show decreased intrinsic activity in women with anorexia nervosa and those who had recovered from the disease compared to controls. The basal ganglia (BGN) and sensorimotor networks (SMN) were also investigated. Methods Between January 2008 and January 2012, women with restricting-type anorexia nervosa, women who recovered from the disease and healthy control women completed functional magnetic resonance imaging during a conditioned stimulus task. Network activity was studied using independent component analysis. Results We studied 20 women with anorexia nervosa, 24 recovered women and 24 controls. Salience network activity in the anterior cingulate cortex was reduced in women with anorexia nervosa (p = 0.030; all results false-discovery rate–corrected) and recovered women (p = 0.039) compared to controls. Default mode network activity in the precuneus was reduced in women with anorexia compared to controls (p = 0.023). Sensorimotor network activity in the supplementary motor area (SMA; p = 0.008), and the left (p = 0.028) and right (p = 0.002) postcentral gyrus was reduced in women with anorexia compared to controls; SMN activity in the SMA (p = 0.019) and the right postcentral gyrus (p = 0.008) was reduced in women with anorexia compared to recovered women. There were no group differences in the BGN. Limitations Differences between patient and control populations (e.g., depression, anxiety, medication) are potential confounds, but were included as covariates. Conclusion Reduced SN activity in women with anorexia nervosa and recovered women could be a trait-related biomarker or illness remnant, altering the drive to approach

Anorexia nervosa is complex and difficult to treat. In cognitive therapies the focus has been on cognitive content rather than process. Process-oriented therapies may modify the higher level cognitive processes of metacognition, reported as dysfunctional in adult anorexia nervosa. Their association with clinical features of anorexia nervosa, however, is unclear. With reclassification of anorexia nervosa by DSM-5 into typical and atypical groups, comparability of metacognition and drive for thinness across groups and relationships within groups is also unclear. Main objectives were to determine whether metacognitive factors differ across typical and atypical anorexia nervosa and a non-clinical community sample, and to explore a process model by determining whether drive for thinness is concurrently predicted by metacognitive factors. Women receiving treatment for anorexia nervosa (n = 119) and non-clinical community participants (n = 100), aged between 18 and 46 years, completed the Eating Disorders Inventory (3(rd) Edition) and Metacognitions Questionnaire (Brief Version). Body Mass Index (BMI) of 18.5 kg/m(2) differentiated between typical (n = 75) and atypical (n = 44) anorexia nervosa. Multivariate analyses of variance and regression analyses were conducted. Metacognitive profiles were similar in both typical and atypical anorexia nervosa and confirmed as more dysfunctional than in the non-clinical group. Drive for thinness was concurrently predicted in the typical patients by the metacognitive factors, positive beliefs about worry, and need to control thoughts; in the atypical patients by negative beliefs about worry and, inversely, by cognitive self-consciousness, and in the non-clinical group by cognitive self-consciousness. Despite having a healthier weight, the atypical group was as severely affected by dysfunctional metacognitions and drive for thinness as the typical group. Because metacognition concurrently predicted drive for thinness

The authors conducted a genome-wide association study of anorexia nervosa and calculated genetic correlations with a series of psychiatric, educational, and metabolic phenotypes. Following uniform quality control and imputation procedures using the 1000 Genomes Project (phase 3) in 12 case-control cohorts comprising 3,495 anorexia nervosa cases and 10,982 controls, the authors performed standard association analysis followed by a meta-analysis across cohorts. Linkage disequilibrium score regression was used to calculate genome-wide common variant heritability (single-nucleotide polymorphism [SNP]-based heritability [h 2 SNP ]), partitioned heritability, and genetic correlations (r g ) between anorexia nervosa and 159 other phenotypes. Results were obtained for 10,641,224 SNPs and insertion-deletion variants with minor allele frequencies >1% and imputation quality scores >0.6. The h 2 SNP of anorexia nervosa was 0.20 (SE=0.02), suggesting that a substantial fraction of the twin-based heritability arises from common genetic variation. The authors identified one genome-wide significant locus on chromosome 12 (rs4622308) in a region harboring a previously reported type 1 diabetes and autoimmune disorder locus. Significant positive genetic correlations were observed between anorexia nervosa and schizophrenia, neuroticism, educational attainment, and high-density lipoprotein cholesterol, and significant negative genetic correlations were observed between anorexia nervosa and body mass index, insulin, glucose, and lipid phenotypes. Anorexia nervosa is a complex heritable phenotype for which this study has uncovered the first genome-wide significant locus. Anorexia nervosa also has large and significant genetic correlations with both psychiatric phenotypes and metabolic traits. The study results encourage a reconceptualization of this frequently lethal disorder as one with both psychiatric and metabolic etiology.

It is well-established that prostaglandins (PGs) affect tumorigenesis, and evidence indicates that PGs also are important for the reduced food intake and body weight loss, the anorexia–cachexia syndrome, in malignant cancer. However, the identity of the PGs and the PG producing cyclooxygenase (COX) species responsible for cancer anorexia–cachexia is unknown. Here, we addressed this issue by transplanting mice with a tumor that elicits anorexia. Meal pattern analysis revealed that the anorexia...

Author Summary Two routes to decreasing susceptibility to infection are resistance (the ability to clear pathogens) and tolerance (the ability to limit damage in response to pathogens). Anorexia induced by sickness puts animals into a diet-restricted state, a state that is generally believed to extend lifespan. We asked whether anorexia induced by sickness would alter the immune response. We measured the effects of diet restriction on both resistance and tolerance to two different infections ...

Pharmacotherapy for anorexia nervosa is considered to be of limited efficacy. However, many studies suffer methodological limitations, and the utility of newer drugs in the treatment of anorexia has not been examined yet. Although there have been more fruitful investigations on the efficacy of medication in the management of bulimia nervosa, there are still many unresolved issues regarding the optimal management of partial remission during the acute treatment phase and the intensity and durat...

Context Anorexia nervosa and normal-weight hypothalamic amenorrhea are characterized by hypogonadism and hypercortisolemia. However, it is not known whether these endocrine abnormalities result in reductions in adrenal and/or ovarian androgens or androgen precursors in such women, nor is it known whether relative androgen deficiency contributes to abnormalities in bone density and body composition in this population. Objective Our objective was to determine whether endogenous androgen and dehydroepiandrosterone sulfate (DHEAS) levels: 1) are reduced in women with anorexia nervosa and normal-weight hypothalamic amenorrhea, 2) are reduced further by oral contraceptives in women with anorexia nervosa, and 3) are predictors of weight, body composition, or bone density in such women. Design and Setting We conducted a cross-sectional study at a general clinical research center. Study Participants A total of 217 women were studied: 137 women with anorexia nervosa not receiving oral contraceptives, 32 women with anorexia nervosa receiving oral contraceptives, 21 normal-weight women with hypothalamic amenorrhea, and 27 healthy eumenorrheic controls. Main Outcome Measures Testosterone, free testosterone, DHEAS, bone density, fat-free mass, and fat mass were assessed. Results Endogenous total and free testosterone, but not DHEAS, were lower in women with anorexia nervosa than in controls. More marked reductions in both free testosterone and DHEAS were observed in women with anorexia nervosa receiving oral contraceptives. In contrast, normal-weight women with hypothalamic amenorrhea had normal androgen and DHEAS levels. Lower free testosterone, total testosterone, and DHEAS levels predicted lower bone density at most skeletal sites measured, and free testosterone was positively associated with fat-free mass. Conclusions Androgen levels are low, appear to be even further reduced by oral contraceptive use, and are predictors of bone density and fat-free mass in women with

A growing body of literature has investigated the association between maternal anorexia nervosa and pregnancy outcomes. Infant low birth weight is associated with a number of neurodevelopmental and physical sequelae; however, consistent results on its association with maternal anorexia nervosa are scant. Therefore, a systematic review and meta-analysis of the existing literature were undertaken. PubMed, Embase, and PsychInfo were searched for studies comparing the mean birth weight of babies ...
This article reviews the paper by Liebman, Minuchin, and Baker (1974) describing the use of a family meal as part of an integrated treatment approach for anorexia nervosa. The ideas laid out in the paper are described and discussed in terms of the understanding of anorexia nervosa at the time as well as placed in a current clinical and theoretical context. A comment is made on whether or not, in this author's opinion, the paper stands 'the test of time'.

Eating disorders have captured the attention of medical and dental professionals as well as the public for decades and continue to raise concern today. The literature devoted to anorexia and bulimia highlights myriad psychological, systemic, and dental health complications. Dental practitioners are in a unique position to discover early manifestations of these disorders. The present article reviews anorexia and bulimia, summarizing telltale behavioral traits, systemic manifestations, and dental features to facilitate recognition and enable accurate diagnosis.
Anyone who has experienced influenza or a bacterial infection knows what it means to be ill. Apart from feeling feverish, experiencing aching joints and muscles, you lose the desire to eat. Anorexia, defined as loss of appetite or persistent satiety leading to reduced energy intake, is a hallmark of acute inflammatory disease. The anorexia is part of the acute phase response, triggered as the result of activation of the innate immune system with concomitant release of inflammatory mediators, ...

This study is the second part of a process evaluation, embedded in the MOSAIC study, a large randomised controlled trial comparing two different psychological therapies, the Maudsley Model for Treatment of Adults with Anorexia Nervosa (MANTRA) and Specialist Supportive Clinical Management (SSCM). The study adopted a qualitative approach to examine patient experiences of the two treatments. Seventeen semi-structured interviews were conducted with Anorexia Nervosa and Eating Disorder Not Otherwise Specified-Anorexia Nervosa type patients, and transcripts were analysed thematically. Patient responses yielded five main themes: positive and helpful aspects, beneficial outcomes, less helpful aspects, possible improvements to the treatments, and the therapeutic and external environment. The findings show clear differences and some overlaps between patients' views on MANTRA and SSCM. Both therapies were experienced by patients as credible and largely helpful, albeit in different ways. These results are in agreement with those of therapists' views on these treatments.

Anorexia nervosa is a potentially life-threatening eating disorder where people intentionally refuse to eat sufficient amounts to maintain a healthy body-weight for fear of becoming fat. The intense preoccupation with restriction of food and control of body weight makes this one of the most complex and confusing conditions for practitioners to treat. While no single treatment has been found to be superior to another in the treatment of anorexia nervosa, general practice guidelines are available to guide mainstream treatment, however there are no guidelines for practitioners of complementary therapies. Complementary therapies such as acupuncture show promise as an adjunctive therapy in improving co-morbidities such as depression and anxiety levels among people with anorexia nervosa, by strengthening mind, body and overall well-being. The aim of this guideline is to assist and support acupuncture practitioners to deliver effective and safe adjunctive acupuncture treatments to people with anorexia nervosa, by providing a practice guideline that is underpinned by an ethical and evidence-based framework. The use of complementary therapies and specifically acupuncture in the treatment of anorexia nervosa may provide important adjunctive care to allow a comprehensive treatment approach that potentially improves quality of life, reduces anxiety and instils hope for recovery. It is hoped that acupuncture practitioners treating patients with anorexia nervosa will refer to these guidelines and apply the guidance (as deemed appropriate). Copyright © 2015 Elsevier Ltd.

In cancer anorexia, a decrease in food intake (FI) occurs concomitant with changes in orexigenic peptides such as neuropeptide Y (NPY) and anorexigenic peptides such as alpha-melanocyte-stimulating hormone (alpha-MSH) and anorexigenic neurotransmitter serotonin. omega-3 Fatty acid (omega-3FA) inhibits cytokine synthesis, and delays tumor appearance, tumor growth, and onset of anorexia in tumor-bearing rats. We hypothesize that, in cancer anorexia, omega-3FA is associated with quantitative reversal of hypothalamic NPY, alpha-MSH, and serotonin receptor (5-HT(1B)-receptor) enhancing FI. Fischer rats were divided into: MCA tumor bearing fed chow (TB-Chow) or omega-3FA diet (TB-omega-3FA) and controls: non-tumor bearing fed chow (NTB-Chow) or omega-3FA diet (NTB-omega-3FA). Rats were euthanized at anorexia and brains were removed for hypothalamic immunohistochemical study, using NPY, alpha-MSH, and 5-HT(1B)-receptor-specific antibodies and slides assessed by image analysis. Immunostaining specificity was controlled by omission of primary or secondary antibodies and pre-absorption test. At anorexia, FI decreased (P anorexia, concomitant with an increase in FI, were probably mediated by omega-3FA inhibition of tumor-induced cytokines.
The eating disorders literature has focussed on females and little is known of the male experience. The overall image this has generated suggests a young woman in conflict with socio-cultural pressures which associate thinness with beauty. Historical studies have examined anorexia nervosa from an entirely female focus while ignoring how diagnostic categories have shaped approaches to the male body. This paper will track the case of the male with anorexia nervosa through changing theories of causation and treatment approaches, from when the condition first emerged in 1873 to the present. In doing so, we gain a valuable new insight into how anorexia nervosa has been historically gendered and the far-reaching implications this has had for diagnosis and treatment of the male sufferer. Similarities between the sexes helped to establish male anorexia as a distinct category. However, this shifted focus away from important differences, which have yet unexplored implications in the assessment, diagnosis and management of disordered eating. Throughout history, there has been constant pressure to give a precise definition to anorexia nervosa, despite being fraught with medical uncertainties. This has resulted in inevitably harmful generalisations rooted in the dominant epidemiology. This paper reveals that anorexia nervosa is a truly global phenomenon which cannot be adequately constructed through exclusive studies of the female. There is consequently a pressing need to address the dearth of research examining eating disorders in males.

Anorexia nervosa is a severe eating disorder often leading to malnutrition and cachexia, but its pathophysiology is still poorly defined. Chronic food restriction during anorexia nervosa may induce gut barrier dysfunction, which may contribute to disease development and its complications. Here we have characterized intestinal barrier function in mice with activity-based anorexia (ABA), an animal model of anorexia nervosa. Male C57Bl/6 ABA or limited food access (LFA) mice were placed respectively in cages with or without activity wheel. After 5 days of acclimatization, both ABA and LFA mice had progressively limited access to food from 6 h/d at day 6 to 3 h/d at day 9 and until the end of experiment at day 17. A group of pair-fed mice (PF) was also compared to ABA. On day 17, food intake was lower in ABA than LFA mice (2.0 ± 0.18 g vs. 3.0 ± 0.14 g, p anorexia nervosa. The role of these alterations in the pathophysiology of anorexia nervosa should be further evaluated. Copyright © 2013 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Full Text Available BACKGROUND A crude rate of mortality of 5% has been quoted for anorexia nervosa in recent studies. Nowadays the mechanism of death is unclear and various authors recommend that any anorexia nervosa death be reported and that, where possible, an autopsy be performed. METHODS In this work we present a case of sudden death in anorexia nervosa with unexpected autopsy findings. A 21-years-old woman with long-standing anorexia nervosa, severely underweight with a body mass index of 14.47 kg/m2, has been taken to the Emergency Department in very critical conditions. Despite the attempts of resuscitation, she died shortly afterwards. Therefore an autopsy has been requested in order to clarify the causes of death. RESULTS The clinical picture, laboratory parameters, histology and microbiological investigations were consistent with pneumococcal sepsis associated adrenal apoplexy. CONCLUSIONS The cause of death in anorexia nervosa cannot reliably be established from antemortem clinical features. All anorexia nervosa deaths should be reported together with description of necropsy. This may lead to advances in the knowledge and treatment practices.

Links between media portrayals of celebrities and participation in activities related to anorexia are of interest to both researchers and practitioners but are difficult to study over long time periods and in large populations. Here we aim to determine the links between media portrayals of celebrities and online practices related to anorexia. We examined the Internet searching activities of 9.2 million people, focusing on searches related to known celebrities, especially those perceived by the public as suffering from anorexia, and on searches indicative of anorexic practices. Additionally, we tracked media attention of individual celebrities by monitoring all messages from Twitter related to those celebrities. We found that a subset of users focus their browsing activities on celebrities perceived as anorexic. There was an increase of 14% in the hazard of performing anorexia-related searches after searching for information on the celebrities most perceived as anorexic. Media attention of a celebrity was a trigger for search activity, and when focused on a celebrity perceived as anorexic, resulted in a 33% increase in hazard for carrying out anorexic searches. Strikingly, when media attention included a reference to anorexia, the hazard decreased by 22%. Our findings suggest that it would be beneficial for media, when reporting on those celebrities who are known to suffer from anorexia, to include this information in their reporting.

Anorexia is one of the most common symptoms associated with illness and constitutes an adaptive strategy in fighting acute infectious diseases. However, prolonged reduction in food intake and an increase in metabolic rate, as seen in the anorexia-cachexia syndrome, lead to depletion of body fat and protein reserves, thus worsening the organism's condition. Because the central nervous system controls many aspects of food intake, soluble factors known as cytokines that are secreted by immune cells might act on the brain to induce anorexia during disease. This review focuses on the communication pathways from the immune system to the brain that might mediate anorexia during disease. The vagus nerve is a rapid route of communication from the immune system to the brain, as subdiaphragmatic vagotomy attenuates the decrease in food-motivated behavior and c-Fos expression in the central nervous system in response to peripheral administration of the proinflammatory cytokine, interleukin-1beta, or bacterial lipopolysaccharide. At later time points after peripheral lipopolysaccharide administration, interleukin-1 itself acts in the brain to mediate anorexia and is found in the arcuate nucleus of the hypothalamus. The mechanisms by which interleukin-1beta gains access to the brain and the potential role of neuropeptide-Y-containing neurons in the arcuate hypothalamus in mediating anorexia during disease are discussed.
This paper argues that there is a relationship between understandings of anorexia nervosa (AN) and how the ethical issues associated with involuntary treatment for AN are identified, framed, and addressed. By positioning AN as a construct/discourse (hereinafter "AN: the diagnosis") several ethical issues are revealed. Firstly, "AN: the diagnosis" influences how the autonomy and competence of persons diagnosed with AN are understood by decision-makers in the treatment environment. Secondly, "AN: the diagnosis" impacts on how treatment and treatment efficacy are defined and the ethical justifiability of paternalism. Thirdly, "AN: the diagnosis" can limit the opportunity for persons with AN to construct an identity that casts them as a competent person. "AN: the diagnosis" can thus inherently affirm professional knowledge and values. Postmodern professional ethics can support professionals in managing these issues by highlighting the importance of taking responsibility for professional knowledge, values, and power and embracing moral uncertainty.

Anorexia nervosa (AN) is a psychiatric illness with minimal effective treatments and a very high rate of mortality. Understanding the neurobiological underpinnings of the disease is imperative for improving outcomes and can be aided by the study of animal models. The activity-based anorexia rodent model (ABA) is the current best parallel for the study of AN. This review describes the basic neurobiology of feeding and hyperactivity seen in both ABA and AN, and compiles the research on the role that stress-response and reward pathways play in modulating the homeostatic drive to eat and to expend energy, which become dysfunctional in ABA and AN.

Anorexia nervosa presenting as Wernicke-Korsakoff syndrome is rare. The causes of Wernicke-Korsakoff syndrome are multiple like alcohol abuse, thyrotoxicosis, haemodialysis, severe malnutrition because of gastric carcinoma and pyloric obstruction, hyperemesis gravidarum, and prolonged parenteral feeding. We report a case of anorexia nervosa, who presented with Wernicke's encephalopathy and progressed to Korsakoff's syndrome. Knowledge, awareness, and early intervention of anorexia nervosa by mental health professionals can prevent development of Wernicke-Korsakoff syndrome.

The principal aims of the present study were to explore the prevalence of anorexia and the factors correlated to anorexia in a large population of older people living in nursing home. Secondary, we evaluated the impact of anorexia on 1-year survival. Data are from baseline evaluation of 1904 participants enrolled in the Un Link Informatico sui Servizi Sanitari Esistenti per l'Anziano study, a project evaluating the quality of care for older persons living in an Italian nursing home. All participants underwent a standardized comprehensive evaluation using the Italian version of the inter Resident Assessment Instrument Minimum Data Set (version 2.0) for Nursing Home. We defined anorexia as the presence of lower food intake. The relationship between covariates and anorexia was estimated by deriving ORs and relative 95% CIs from multiple logistic regression models including anorexia as the dependent variable of interest. Hazard ratios and 95% CIs for mortality by anorexia were calculated. More than 12% (240 participants) of the study sample suffered from anorexia, as defined by the presence of decreased food intake or the presence of poor appetite. Participants with functional impairment, dementia, behavior problems, chewing problems, renal failure, constipation, and depression, those treated with proton pump inhibitors and opioids had a nearly 2-fold increased risk of anorexia compared with participants not affected by these syndromes. Furthermore, participants with anorexia had a higher risk of death for all causes compared with nonanorexic participants (hazard ratio 2.26, 95% CI: 2.14-2.38). The major finding is that potentially reversible causes, such as depression, pharmacologic therapies, and chewing problems, were strongly and independently associated with anorexia among frail older people living in nursing home. Furthermore, anorexia was associated with higher rate of mortality, independently of age and other clinical and functional variables. Copyright © 2013

Anorexia nervosa (AN) continues to remain poorly understood within eating disorders. Recent research and theory have moved away from understanding its aetiological causes, addressing instead potential maintaining factors. This study is focused on interpersonal maintenance factors: the response of close others. Relatives of those with AN typically carry the main burden of care, and research has found high levels of carer distress and unmet needs. Recent theories have proposed this emotional impact to contribute to expressed emotion and other unhelpful caregiver interactions which inadvertently maintain AN. One such understudied response is accommodation, described as a 'process' whereby caregivers 'assist or participate' in symptomatic behaviours of the cared for individual. There is a dearth of research relating to accommodation within eating disorders, particularly qualitative accounts. This study utilized a grounded theory methodology to explore caregivers' responses to managing AN, focusing particularly on carers' experience of accommodation. Eight participants with experience of caring for an individual diagnosed with AN were interviewed. Participants were recruited from a national eating disorder charity and regional eating disorder service. A number of themes emerged, including the importance of caregivers' emotional resources in mediating accommodation responses. Low-perceived efficacy over AN contributed to caregiver burnout. Decreased emotional resources influenced a shift in caregiving aims conducive with accommodation. Nevertheless, carers perceived accommodation as counterproductive to recovery and consequently experienced internal conflict (cognitive dissonance). Dissonance was reduced using a number of cognitive and behavioural strategies. The implications of these findings are discussed with reference to existing literature.
