Filter by:The primary aim of this study is to study how Repetitive Transcranial Magnetic Stimulation (rTMS) tailored to specific anorexia nervosa (AN) or bulimia nervosa (BN) brain activation alterations will promote recovery and to study how inhibitory tDCS (Transcranial Direct Current Stimulation) will reduce symptoms of body image distortion in a second sample of AN and BN groups.
The purpose of this study is to use positron emission tomography (PET) imaging and magnetic resonance imaging (MRI) to understand the brain function of individuals with anorexia nervosa and healthy controls.
Anorexia nervosa (AN) is a frequent, potentially life-threatening eating disorder characterized by a resistance to maintaining body weight at or above a minimally normal weight for age and height, an intense fear of weight gain or being "fat" even though underweight, a loss of menstrual periods in girls and women post-puberty and a disturbance in the experience of body weight or shape. Body weight and shape dissatisfaction is linked to the development, maintenance and relapse of AN. Neuroimaging studies have shown that the inferior parietal cortex is involved in body image perception and less activated in patients with AN compared with healthy subjects. Repetitive transcranial magnetic stimulation (rTMS) is used to modulate cortical excitability, and particularly to increase excitability with high-frequency rTMS. The aim of this study was to investigate the effect of "excitatory" high-frequency rTMS over the "hypoactive" inferior parietal cortex of 54 patients with AN. This randomized, double-blind, placebo-controlled study will compare effective rTMS (2000 ten-Hz stimulations per session, applied at 90% of the resting motor threshold, with 10 sessions in two weeks) versus placebo rTMS. Assessments will be performed before rTMS and after the last rTMS session (immediately after, at 15 days and three months). The principal criteria for judgement is a body image satisfaction scale (Boby Shape Questionnaire, BSQ-34). The secondary criteria for judgement are eating behaviour scales (Eating Attitude Test, EAT-40; Bulimia test, BULIT and Eating Disorders Inventory, EDI-2), the Hamilton depression rating scale and Hamilton anxiety rating scale, a quality of life scale (Short-Form Health Survey, SF-36), a body composition analysis using a Dual-energy X-ray absorptiometry and the alpha-MSH autoantibodies levels (biomarker for eating disorders recently described). Inferior parietal cortex rTMS could not only improve body image perception, but also help in the treatment of eating disorders, allowing weight gain with a decreased anxiety and improving patients' quality of life. Also positive results could have direct therapeutic implications with the possibility to complete regular rTMS sessions, or to implant extradural electrodes for chronic parietal cortex stimulation.
Athletes in particular elite athletes have obsessional food and body concerns, in bond with a worship of the performance more and more invading, which lead to clinical and subclinical eating disorders. These eating disorders differ according to the disciplines and are difficult to diagnose in athletes because there are insufficiently described. Our aim at estimating the frequency of eating disorders in athletes and describing eating disorders by means of somatic, dietetic and psychological evaluations.
RATIONALE: Megestrol acetate may help improve appetite and lessen weight loss caused by cancer. PURPOSE: This clinical trial studies megestrol acetate in treating weight loss or anorexia in young patients with malignancies who are undergoing radiation therapy and/or chemotherapy.
The purpose of this trial is to evaluate the safety and efficacy of the atypical antipsychotic, olanzapine, for the treatment of youth suffering from Anorexia Nervosa (AN). Adolescent males and females between the ages of 11 and 17 years who are being treated by a physician on the Eating Disorder team at the Children's Hospital of Eastern Ontario will be invited to join the study if they have been diagnosed with AN or Eating Disorder Not Otherwise Specified (EDNOS), and if they weigh less than or equal to 85% of their ideal body weight. Those who meet inclusion and not exclusion criteria, and consent to participating in the trial will be offered adjunctive treatment with olanzapine. Those who agree to take olanzapine will belong to the olanzapine group, and those who decline will belong to the comparison group. Olanzapine doses will be in keeping with the investigators current clinical practice, with flex doses ranging from 1.25 mg to 10.0 mg daily (the majority of patients are treated with 2.5 mg or 5.0 mg at bedtime); dose adjustments made based on individual need and tolerability. Participants will remain in the study for 12 weeks. Those who initially decline olanzapine treatment may change their minds and take olanzapine up until week 9 of the trial. It is hypothesized that those children and adolescents who choose to take olanzapine at entry into the trial will be more motivated to recover and more compliant with treatment. Compared to those who do not receive medication, it is expected that these adolescents will demonstrate reduced disordered eating attitudes and behaviours, as well as an increased rate of weight gain. Finally, it is predicted that the rates of discontinuation and the adverse effects of olanzapine will be minor given the relatively low dose (as compared to treatment for patients with schizophrenia), slow titration, and short-term use of olanzapine the investigators will be using. By comparing the well-being and outcome of patients in the two groups, the investigators hope to begin to answer the question of whether olanzapine does or does not lead to improved clinical outcome for patients with severe eating disorders such as AN or EDNOS, and the question of whether the benefits of using the medication outweigh the risks.
To compare the effect of megestrol acetate concentrated suspension and placebo on caloric intake in patients with cancer-associated anorexia.
Purpose of the study is to compare the effects of megestrol acetate concentrated suspension and placebo on caloric intake for the treatment of cancer-associated anorexia in patients with lung or pancreatic cancer
Research studies raise the possibility that medications such as quetiapine may improve mood or reduce obsessions in people with anorexia nervosa and may even help to normalize appetite. The medication quetiapine also known as seroquel works by activating certain systems in the brain, such as ones known as dopamine and serotonin chemical systems in the brain.
Primary: - To determine if treatment with Haelan (fermented soy product) can decrease the severity of poor appetite measured using a visual analog scale (VAS) of 0 to 100 mm (0 mm = best, 100 mm = worst) at week 4 +/- 5 days. - To determine if treatment with Haelan can decrease the severity of nausea, fatigue, and improve patients' overall sense of well being measured using a VAS of 0 to 100 mm (0 mm = best, 100 mm = worst) at week 4 +/- 5 days. - To determine if treatment with Haelan can increase patient's calorie intake, albumin, pre-albumin, anthropometric measure, lean body mass (measured by bio-impedence analysis), and weight at week 4+/- 5 days. - To determine if treatment with Haelan can decrease patient's Functional assessment of anorexia/cachexia therapy subscales or (FAACT) and the Functional Assessment of Chronic Illness Therapy with fatigue subscales (FACIT-F) at week 4+/- 5 days. - To assess the feasibility of accrual, and adherence to the Haelan consumption. Secondary: - Determine the plasma isoflavone activity, 12-MTA and 13-MTA of these patients. - Correlate the biologic modulation of peripheral blood lymphocyte NF-kB by Haelan with primary outcome in these patients. - To determine if treatment with Haelan can increase patient's functional status at week 4+/- 5 days.
