Filter by:Body Image distortion is a key diagnostic feature for Anorexia Nervosa. Patients suffering from Anorexia Nervosa tend to perceive themselves as fatter than they are. This bias might be at the origin of a reinforcement of anorectic behavior which might alter medical care. The objective of this study is to identify neural correlates of self-recognition in Anorexia Nervosa. Patients are hypothesized to activate the self-recognition network when seeing images of a fatter body shape than their own.
Patients with anorexia nervosa (AN), a serious psychiatric disorder, exhibit restricted dietary intake and endorse fear of consuming calorie-dense foods, which in turn drives weight loss. Premorbid anxious personality traits and comorbid anxiety disorders are common in patients with AN. Although intensive behavioral treatment programs can achieve weight restoration in a majority of adults with AN, relapse rates are high. Predictors of relapse include elevated state anxiety and low dietary variety, including lower intake of fat, after discharge, which suggests that relapse following weight restoration may be related to inadequate fear extinction to high energy density (ED) foods during treatment and consequent resumption of restrictive eating patterns. Despite evidence of anxiety's role in the onset and maintenance of restricted eating behavior, utilizing exposure and response prevention (EX-RP) and meal-based interventions to reduce food-related fears is understudied. EX-RP is the gold standard of treatment for Obsessive Compulsive Disorder (OCD). This proposal aims to test the efficacy of an adjunct meal-based EX-RP intervention to reduce food-related fears during intensive behavioral weight restoration in hospitalized patients with AN in comparison to a control treatment, Motivational Interviewing. The investigators will assess changes in a) self-reported anxiety regarding consumption of high-ED foods, b) physiological (skin conductance and heart rate variability) responses to imagined consumption of food items elicited utilizing a visual food cue task, and c) caloric intake of a challenging test meal pre- and post-treatment. A secondary aim is to assess the relationship of early treatment response to EX-RP, operationalized as a reduction in self-reported anxiety within the first three weeks of treatment, and end-of-treatment as well as six-month post-discharge outcomes. Helping patients tolerate food-related anxiety and increase dietary variety across meal contexts may augment treatment effectiveness in adult patients during intensive treatment for AN and has potential to decrease relapse rates.
Multicenter, randomized, double-blind, parallel-group, placebo-controlled study to evaluate the efficacy and safety of anamorelin HCl. Approximately 316 patients with advanced NSCLC with cachexia will be randomized 1:1 to anamorelin HCl 100 mg or placebo, taken orally once daily (QD) for a total of 24 weeks. Patients will be instructed to take the study drug at least 1 hour before their first meal of the day

Anorexia nervosa is an eating disorder whose symptomatology induces a modification of the intestinal microbiota. To date, studies have shown variable profiles without linking them to metabolic and neuropsychological energy phenotyping. This intestinal dysbiosis could be involved in the maintenance of the disorders. Bidirectional communication channels exist between the microbiota, the intestine and the brain. Anomalies in these pathways could explain the impact of the microbiota on the pathophysiology of anorexia nervosa. Therapeutic interventions would then be possible to restore the microbiota in anorexia nervosa and influence the treatment of this disease. This study aims to explore the hypothesis of disruption of the microbiota-intestinal-brain axis transversely and measuring the intestinal microbiota, urinary metabolome, biological factors nutritional, immunological and physiological plasma plasma of the intestine, and finally, the psychological dimensions characteristic of anorexia nervosa.
Anorexia nervosa (AN) is a comparably low-prevalent illness. Chronic courses are often and the mortality rate of patients with AN is higher than in any other mental illness. A major influence on the course of the illness is the interval between the onset of AN symptoms and the beginning of an adequate treatment (duration of untreated illness, DUI). Patients with AN have a better prognosis if treated early. Previous large-scale interventions have not shown the desired positive effects on the DUI. Therefore, an important starting point seems to be a better initial understanding of the factors influencing the DUI, which is the major aim of this project. The planned mixed-method study is divided in three consecutive sub-studies. The first substudy aims to identify modifiable factors influencing the DUI using semi-structured interviews and a multi-informant approach (patients, carers, physicians). As a result of this qualitative analyses using Grounded Theory the most relevant factors will be determined. The motivation of the second substudy is to condense the factors identified to influence the DUI into a checklist and to conduct a first psychometric evaluation of this newly developed instrument. The third substudy aims to quantitatively determine the magnitude of the effects of a) a priori determined non-modifiable factors and b) the modifiable checklist-factors using a multi-informant approach (planned n for each informant = 130; 13 co-operating specialized clinics and 6 cooperating outpatient partners). Additional outpatient partners may be recruited during the course of the study. In conclusion, the study aims to derive recommendations for effective secondary prevention. Thereby, the study might ultimately contribute to earlier treatment initiation of patients with AN, and to the prevention of chronic courses and the associated high health care costs and individual burden.
This study evaluates if imaginal exposure therapy can decrease symptoms of eating disorders and anxiety, and test an online format of IE to maximize its ability to reach as many individuals with eating disorders as possible. All participants will complete four imaginal exposure sessions and will complete questionnaires prior to receiving this treatment, as well as complete follow up questionnaires at 1-month, 6-month, and 12-month.
A growing qualitative literature about personal recovery process in mental disorders emerges. However in Anorexia Nervosa (AN), it remains few understood, especially in severe AN during adolescence. This pilot study seeks to enhance understanding of recovery from AN in France and support the dissemination of the PR paradigm among the French mental health community working with AN, as a complement to the medical approach. A qualitative research according to Interpretative Phenomenological Analysis (IPA) method was conducted .Five young women hospitalized ten years before for a severe AN during their adolescence were interviewed with a semi-structured face-to-face interview on recovery process.
To improve treatment for patients with severe anorexia nervosa admitted for inpatient care, and to help their families. Inpatients and their families will be offered a novel intervention which includes multimedia training materials. These materials provide guidance in how families can provide support to maintain and build on changes made during inpatient care
The purpose of the study is to evaluate the use of a new brain stimulation tool called transcranial direct current stimulation (tDCS). tDCS is a new technique used to stimulate the brain. The investigators believe that it may help to change brain function in individuals with anorexia nervosa. The brain stimulation occurs outside the head. The tDCS procedure involves applying a small amount of electrical current across the scalp, for a short period of time. This small electrical current is able to change the electrical activity inside areas of the brain. In the current study, the investigators will ask participants to complete computer-based brain training sessions. While participants do the brain training exercises, they will receive either real tDCS for "sham" tDCS. "Sham" tDCS means that participants might feel sensations like tingling or vibrations from the tDCS machine, but will not actually receive the electrical current. Investigators will also ask participants to complete several tests to assess changes in brain function. The information gained from this study will help investigators to understand how tDCS could be used to improve brain function and learning in individuals with anorexia nervosa.
