Nicotine in Treating "Hunger Pain" in Patients With Malignant Bowel Obstruction Caused By Cancer...
AnorexiaConstipation6 moreRATIONALE: The use of a nicotine inhaler may help decrease appetite and relieve "hunger pain" (an intense craving for food) in patients with malignant bowel obstruction caused by cancer. PURPOSE: This randomized clinical trial is studying the side effects and how well a nicotine inhaler works in treating "hunger pain" in patients with malignant bowel obstruction caused by cancer.
Eating Concerns and Compulsivity
Anorexia Nervosa in RemissionEating DisorderThis study uses a computational task to examine differences in adaptive learning to both rewards and punishments between three groups: those who have recovered from anorexia nervosa, those who score highly on the EAT-26 (Eating Attitudes Test - 26 item version; an eating disorder symptom scale), and healthy controls. This task also allows the examination of pupil response (thought to reflect norepinephrine activity) in response to expected and unexpected wins and losses.
Accumbofrontal Tract Study in 2 Populations of Patients With Anorexia Nervosa and Obsessional Compulsive...
Accumbo Frontal TractRestrictive anorexia nervosa and TOCs are psychiatric diseases which shares a common pathophysiological substrate We hypothesize that anorexia patients and patients with OCD have structural and functional changes in the accumbofrontal tract. The main objective of this study will be to compare the structure and the connectivity of this tract in MRI with diffusion sequences (DTI tractography) and resting-state, in 3 distinct populations of anorexic patients, patients with OCD and healthy patients. The role of the accumbo-frontal tract in the cortico-striato-hypothalamo-cortical circuit seems to be established. DTI tractography will allow the measurement of functional anisotropy (FA), a parameter that evaluates the diffusion of water molecules along the white matter fibers, and therefore the potential alteration of the studied tract. Resting state sequences will allow to estimate the BOLD signal and the functionality of the tract.
Impaired Regulation of Energy Balance in Elderly People (Balance Study)
Anorexia of AgeingOver the past century life expectancy has risen rapidly. As a result, the proportion of elderly people continues to grow. Elderly people probably have an impaired regulation of energy balance (energy intake versus energy expenditure) whereby the underlying physiological mechanisms are not fully understood. The first objective of this study is to provide further evidence for an age-related failure to regulate energy balance in elderly. If the hypothesis of impaired regulation of energy balance in elderly is confirmed then the second objective becomes to elucidate the underlying physiological mechanisms of the age-related failure to regulate energy intake in elderly.
The Effects of Written Emotional Disclosure on Eating Disorder Pathology in a Clinical Eating Disordered...
Anorexia NervosaBulimia Nervosa1 moreA technique that has been found to be effective at relieving the physical and psychological symptoms associated with inhibiting emotions and emotional thoughts is written emotional disclosure. The goal of this study is to evaluate the effectiveness of written emotional disclosure on the remediation of eating disorder behaviour, cognitions, and management of emotions.
Alprazolam and Eating Behavior in Anorexia Nervosa
Anorexia NervosaThis study examines the role of anxiety in food intake among patients with AN by measuring caloric intake in a standardized, laboratory meal with alprazolam versus a placebo. Patients will participate in two test meal sessions, one after receiving alprazolam and one after receiving a placebo. Patients will be administered psychological measures of anxiety, mood, and eating behavior. Primary outcomes include caloric intake in a laboratory test meal and pre-meal anxiety levels.
Energy Homeostasis in Anorexia Nervosa
Anorexia NervosaThe purpose of this study is to investigate the potential biological predispositions that contribute to the difficulty patients with anorexia nervosa have in maintaining normal weight.
Microbiome Shifts in Adolescent Anorexia Nervosa
Anorexia NervosaThe aim of this study is to evaluate the effect of starvation and recovery in adolescent anorexia nervosa patients in regard to microbiome activity and composition and to elucidate potential connections between weight gain, depression and other comorbidities, further to capture hormone levels and inflammation parameters in a longitudinal design.
Retrospective Examination of Electroencephalography Signals of Individuals With Different Eating...
Anorexia NervosaBulimia NervosaThe aim of this study was to investigate the difference between electroencephalography (EEG) data and current psychological status of individuals diagnosed with anorexia nervosa (AN) and bulimia nervosa (BN).
Efficacy Study of an Olfactory Stimulation Program for the Recuperation of Autobiographical Memories...
AnorexicThe purpose of this study is to estimate the impact of an olfactive stimulation, in relaxing environment, on the access at the autobiographical memories in anorexic patients.
