Bulimia nervosa is a severe psychiatric disorder characterized by recurrent binge eating episodes followed by inappropriate compensatory behavior to prevent weight gain such as self-induced vomiting. With this project, the investigators want to investigate the role of the neurotransmitter dopamine in bulimia nervosa. Dopamine is reported to have an important influence on the neural reward system and is involved in the processing of gains and losses. The reward system is functionally connected to the individual perception of rewards in the environment. A previous study revealed that under catecholamine depletion including dopamine depletion women suffering from bulimia nervosa in their past reported mild bulimic symptoms and their reward processing became dysfunctional: their ability to use rewarding stimuli for task solving was diminished. The aim of this study is to investigate the role of reduced dopamine availability in the development or maintaining of bulimia nervosa and in the dysfunctional processing of rewarding stimuli and negative visual information. Therefore, the investigators hypothesize that catecholamine depletion achieved by oral administration of alpha-methyl-paratyrosine (AMPT) will induce mild bulimic symptoms in females suffering from bulimia nervosa in their past. In addition, they will reveal dysfunctions in reward and emotional processing under catecholamine depletion. Using functional magnetic resonance imaging, the investigators propose that a reduced activation of the nucleus accumbens, a neural structure of the reward system, will be the neural correlate of this dysfunctional reward processing. Furthermore, the amygdala, a neural structure that is involved in emotional processing, will show a higher activation under catecholamine depletion. Genetic factors additionally have an influence on the dopaminergic system. Therefore, the investigators hypothesize that genetic factors, for example the COMT val-158-met polymorphism may have an effect on the behavioral and neural response to catecholamine depletion. In sum, this investigation may help to understand which changes in reward and emotional processing may lead to a reoccurrence of bulimic symptoms. In future, the findings of this study may help to develop individual pharmacological and psychotherapeutical interventions to enhance the outcome of treatment.
Vitamin B1 (Thiamine) is a water soluble essential nutrient; it is synthesized by a variety of plants and microorganisms. Since animals usually cannot synthesis it, humans must be supplied with exogenous vitamin B1 in the diet. The human storage of thiamine is small- about 30mg, an intake of 1-2 mg a day is needed to maintain this pool. Deficiency might occur when the vitamin is depleted from the diet in a short period. Vitamin B1 has a role in energy metabolism and main biosynthetic pathways. Low thiamine causes illnesses in the central and peripheral nervous systems as well as affecting the heart and gastrointestinal systems. Deficiency may occur from malnutrition of different mechanisms such as alcoholism, lack in diet and recently secondary to anti-obesity surgery and few case reports described eating disorders as the reason for developing deficiency causing neuropathy, (1,2) and encephalopathy (3,4,5). One of the presentations of thiamine deficiency is peripheral neuropathy mimicking Guillain-Barre syndrome, and administering the lacking vitamin improves the symptoms. One study examined the prevalence of vitamin B1 deficiency in adult anorexia nervosa patients (6) by measurement of the activation of the enzyme erythrocyte transketolase following addition of thiamin pyrophosphate and comparing them to control of blood donors. This study found significant lower levels of vitamin B1 in the anorectic patient compared to the controls. Rational of the study: The investigators assume that these few cases described of overt neurologic impairment due to vitamin B1 deficiency because of distorted eating are just the "tip of the iceberg" and more eating disorders patients lack thiamine, that may have neuropsychiatric effect on the illness and identifying and treating the shortage may improve the symptoms of the disorder and maybe even the distorted thoughts that are fundamental in eating disorders.
Strength training has been found effective for enhancement of bone health, muscle strength and body composition among premenopausal women from the general population, however it is unclear to what extend strength training might improve these parameters among women with eating disorders. The aim of this study is therefore to examine acute and long-term effects of strength training among persons with eating disorders. The study is a randomized, controlled, single-blinded trial with three intervention groups and one control group. The three intervention groups will perform different volumes of strength training. The intervention period is 16 weeks with three sessions per week. At pretest, posttest, and 6 months, 12 months and 24 months follow-up, the following variables will be measured: bone health, muscle strength, power, body composition hormone levels, physical activity level and compulsivity, body awareness, quality of life, and eating disorders psychopathology. Qualitative in-depth interviews will be carried out to explore the participants' experiences with strength training. The study is carried out in Norway, and is performed in collaboration with Telemark University College, University of Agder, Norwegian school of sport sciences and Modum Bad psychiatric center. The results from the study might implicate on strength training as part of treatment for eating disorders.
Background: research show that cognitive behavioral therapy (CBT) is effective inreducing bulimia nervosa (BN) and binge eating disorder's (BED) symptoms. Today, with the development of technology there are efforts being made for developinga treatment to these eating disorders threw the media, most of these attempts are based on the CBT method. The size of the effect that CBT given threw the internet has on BN and BED is still not entirely clear. Research presented today are mostly based on treatments that were given threw email or Skypeor an automatic self- help stage program. These researches show heterogenic results about the effect it had on eating disorders. In this research we aim to investigate the effect size that a CBT treatment threw a smartphone application that combines a clinician online reply and an automatic feedback in addition to astandard ones a week clinic treatment has on BN and BED symptoms frequency. Methods: Our aim is to make a research using an application that treats that offers an automatic and human therapist and dietitian reply threw a similar application that is suited for them. A selected 40 BN or sub-threshold BN or BED patients, men and women ages 18-60 ,that will turn to the "Sheba eating disorder medical center" will include the research. Half of the participants will receive aCBT treatment threw a smartphone application along with astandardclinical treatment that includes ones a week session with a therapist and ones a week session with a dietitian and the other half will receive a standardclinic treatment alone. We will test the eating disorder symptoms using eating disorders questionnaires at the starting point, at the end of a six months treatment and six months after finishing the treatment. Importance: This research will allow testing the need and benefit that a personal and direct patient- therapist connection has over a standardones a week meeting connection format. In addition, treating with a web application in the future might have a benefit of saving time spent on getting to the clinic, will allow to shorten the time of the session in the clinic and will save cost of the face to face treatment.
To demonstrate the effectiveness of an easily administered intervention (guided self help) aimed at reducing binge eating in patients undergoing bariatric surgery. The investigators hypothesize that patients who have guided self help pre-operatively will have reduced episodes of bingeing pre-operatively compared to those having treatment as usual (bariatric surgery), which will be maintained in the post-operative period, and will be associated with improved weight loss and psychological outcomes after surgery.
"Eating disorders" includes anorexia nervosa, bulimia nervosa, binge eating and other specified feeding or eating disorder (OSFED). Common to all is the intensively occupation to control food intake, body image and body weight. Most people with this kind of disorder don't reach for professional help, or there may be more than 4 years before they do. Cognitive behavior therapy is the foremost method of treatment of eating disorders, but up to 30-50% of the patients don't respond to this. The investigators find it important to identify science based alternatives of therapy, as this may reduce the health concern, and broaden the choice of therapy methods. A former study by Sundgot-Borgen et al in 2002, found guided physical activity to reduce symptoms of bulimia nervosa just as good as the traditional cognitive therapy. The primary objective of the project is to see whether the combination of physical exercise and dietary therapy is more effective in treating eating disorders, than cognitive therapy. Secondly, the investigators want to see whether there are any differences with regard to the individual satisfaction of treatment method, and to associated costs. Interviews with a sufficient number of participants from the PED-t arm to meet data saturation criteria, and all theraphists in the new treatment offer, will give uniqe insight to experiences with the treatment method and the delivery of treatment.
The purpose of this study is to evaluate two training methods of IPT with mental health service providers in college counseling centers.
The purpose is to evaluate a technologically-enhanced, guided self-help program to reduce eating disorder outcomes in college-age women.
Gut of newborn preterm is sterile, immediately by the mother and the surrounding environment from microbial colonization. As the effects of diet, intestinal flora is rapidly changed. Preterm children significantly delay in the establishment of normal flora,during hospitalization because of no breastfeeding, use of antibiotics, enteral feeding delay, combat disease and other factors. In this study, hospitalized preterm children for the study, the prospective randomized double-blind controlled study, to find oral intestinal bifidobacteria and lactobacilli and bifidobacteria subspecies composition and distribution, and further show intestinal bacteria in premature children case group.
