Filter by:This study uses a meal-challenge protocol to assess if patients with anorexia nervosa show a differential metabolism in response to food in comparison to healthy controls. This study determines how heritable and biochemical factors influence food metabolism in anorexia nervosa in order to develop more effective treatment strategies.
The investigators are conducting a randomized controlled trial using an adaptive design for adolescents (ages 12-18) with anorexia nervosa to compare standard Family Based Treatment (FBT) to adaptive FBT with an Intensive Parental Coaching (IPC) component. If participants do not reach expected milestones by session 4 of treatment, participants may be randomized to receive additional IPC or continue treatment as usual with regular FBT.
The goal of the present study is to investigate metabolic gut-brain signaling and the neural correlates of distraction from visual food cues in patients with Anorexia nervosa and healthy controls.
The researchers propose to utilize a pharmacological approach involving infusions of the sympathomimetic agent isoproterenol to repeatedly trigger cardiorespiratory sensations and anxiety during meal anticipation, to facilitate the development of tolerance or a reduction of the anxiety/fear response in individuals with anorexia nervosa. The investigators aim to conduct a proof of principle study to assess for evidence of initial efficacy of this new treatment approach. As a comparator condition, the researchers propose using repeated administration of saline infusions.
The heart rate variability (HRV) is a measure of the autonomic nervous system (ANS). In the model of anorexia nervosa, ANS is disturbed with mostly a predominance of activation of the parasympathetic nervous system and a decrease of the sympathetic system. Various explanations of this these dysfunctions are proposed in literature, mainly malnutrition, physical hyperactivity, anxiety, that are known characteristics of anorexia nervosa. The primary aim of this study is to evaluate correlation between ANS dysfunction and anxiety in anorexia nervosa. Other objectives of this study are firstly to evaluate correlation between ANS dysfunction and others parameters (weight, body mass index, depression, physical activity, purgative ou restrictive type, duration of disease, smoking) in anorexia nervosa and secondly to see if HRV is a predictive parameter of the evolution of anorexia nervosa.
The purpose of this study is to check if patients, but also relatives (as they share familial and genetic risk factors), are having more difficulties in regulating a spontaneous, pleasant physical effort (doing "too much") compared to healthy controls, and if physical efforts are participating to core symptoms of anorexia nervosa, such as more appetite (instead of less), less pain, more abnormal body image, and less cognitive flexibility. Such a result could help to further understand the role of difficulties with physical exercise as part of the phenotype of anorexia nervosa.
The 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.
This study evaluated the periodontal status of patients suffering from eating disorders (anorexia nervosa and bulimia nervosa). The work hypothesis is that eating disorder patients have a higher risk for periodontal diseases than non-eating disorder subjects.
This study is designed to understand responsiveness to reward in adolescents with restricting-type anorexia nervosa compared with non-clinical controls, and how it is affected by potential-threat perception.
Self-admission is a novel treatment tool whereby patients who are well-known to a service who have high previous utilization of health care are offered the possibility of self-admission to the inpatient ward for up to seven days without having their motive for admission questioned. Patients are free to admit themselves because of deteriorating mental health, acute stress, lack of structure in their everyday life, loneliness, boredom, or any other reason. The patients decide when they want to admit themselves and can discharge themselves at any time. The purpose behind the self-admission model is to increase the availability of inpatient care for severely ill patients, to avoid stressful and possibly destructive visits to the emergency service, and to decrease total inpatient care utilization. Patients offered a contract for self-admission usually have a history of repeated and prolonged hospitalizations. By encouraging them to monitor their own mental health status and allowing them to seek help swiftly when they are feeling poorly, the delay from first signs of deterioration to admission can be minimized and full-blown relapse can be avoided, ultimately reducing the total time spent in hospital. Until now, projects of self-admission have mainly targeted patients with long-standing psychotic disorders, such as schizophrenia, or bipolar disorder. Starting in August 2014, a four-year clinical project at the Stockholm Centre for Eating Disorders began offering self-admission to patients with severe and enduring eating disorders. The purpose of this study is to determine whether this model is viable in a specialized eating disorders treatment setting, if it does lead to increased patient participation and agency and a reduction of the total time spent hospitalized for this particular patient group, and if it is cost-effective.
