Active clinical trials for "Bulimia"

This study aims to examine targets of self-regulatory function among two exemplar populations for which behavior plays a critical role in health outcomes: smokers and individual who binge eat (BED). This is the second phase of a study that aims to identify putative mechanisms of behavior change to develop an overarching "ontology" of self-regulatory processes.

The purpose of this study is to evaluate the effectivity of guided self-help via Internet and bibliotherapy in the treatment of bulimia nervosa (BN) in young women.

This study will evaluate the extent to which we can engage and manipulate putative targets within the self-regulation domain outside of laboratory settings in samples of smokers and overweight/obese individuals with binge eating disorder. Fifty smokers and 50 overweight/obese individuals with binge eating disorder will be recruited to participate in a non-lab experimental paradigm in which we will leverage our novel mobile behavioral assessment/intervention technology platform. We will measure and modulate engagement of potential self-regulation targets and collect data in real time and in real-world conditions. Mobile sensing will be added to up to 50 additional participants.

The specific aim of this study is to assess the efficacy and safety of atomoxetine compared with placebo in outpatients with binge eating disorder.

Bulimic patients suffering from binge eating or "craving" a pressing need to eat, with a sense of unease and anxiety, relieved by food intake. The phenomenon of craving bulimia may be considered appropriately by using paradigms developed in the framework of embodied cognition theories. In bulimic, a study with 20 bulimic patients proved an automatic attraction (unconscious) for food in these patients, as measured by reaction time. Moreover, a therapeutic explored in bulimia (particularly on reducing craving), is repeated transcranial magnetic stimulation (rTMS). Studies have shown that a single session of rTMS to the dorsolateral prefrontal cortex left (DLPFC) reduces significantly the food craving among bulimics, 24 hours after stimulation. But the therapeutic efficacy of TMS on bulimia to more than 24 hours has not yet been demonstrated, and the psycho-cognitive underlying mechanisms have not yet been explored.

The Eva-PED-t project will evaluate implementation of a new therapy for eating disorders, called PED-t (Physical Exercise and Dietary therapy), in a new treatment arena for such illnesses. By this, Eva-PED-t evaluates effectiveness- and efficacy outcomes, with the latter highlighting both the user-, the therapists- and the management perspectives. The research group behind this initiative comprises the founders of the PED-t, and holds extensive expertise on research methodology, eating disorders, health science, and exercise medicine, affiliated high-ranked research-intensive universities. Previous documentation of poor implementation of evidence-based knowledge in public health services reveal poor or no translation of new research findings for improved screening, treatment or medical procedures into real life settings. This may impair public health service outcomes, as less effective or ineffective treatment or procedures are routinely preferred. In a randomized controlled trial, the Eva-PED-t partnership recently found a new therapy for eating disorders (PED-t) to be comparable effective to the currently recommended treatment (NCT02079935). Specific advantages with PED-t, are the use of professionals not currently used in therapy of mental disorders, and the efficiency of arranging therapy in groups, hence effectively dealing with the high request for therapy. The Eva PED-t collaborative is motivated by the knowledge of high prevalence of mental illnesses, for which there is a need to improve treatment access and -efficiency. Adding to this scenario, is the new and more prevalent diagnosis of eating disorders, binge eating disorder, for which specialized health services have no prioritization for treatment. Addressing requirements for improved therapy access demands investigation of new treatments and new ways of delivery. The PED-t responds to this request, still recommendation for a broad implementation necessitate exploration of implementation strategies and experiences.

The purpose of this study is to investigate areas of the brain responsible for appetite regulation. More specifically, the investigators would like to study changes in brain activation, e.g., changes in blood flow and oxygen use of the brain, during two different states: Once when the participants are hungry, and once when the participants are not hungry. The aim is to find out more about the neurobiology of Anorexia and Bulimia Nervosa by comparing women who never had an eating disorder with women who have recovered from Anorexia or Bulimia Nervosa.

This pilot study experimentally manipulates ovarian hormones to examine the direct impact of estrogen (E2) and progesterone (P4) on binge eating symptom burden and the behavioral reward response in women with bulimia nervosa (n=15). This is completed by taking medications that change ovarian hormone levels. This line of research could lead to the development of pharmacological interventions developed to target specific areas of the brain, brain receptors, or pathways identified to be involved in the mechanism underlying ovarian hormone change and binge eating.

This study will evaluate the degree to which engaging targets produces a desired change in medical regimen adherence (across 4-week interventions) and health behavior among smokers (n=50) and overweight/obese persons with binge eating disorder (n=50) (smoking in the former sample and binge eating in the latter sample). The investigators will employ a novel mobile behavioral assessment/intervention platform to engage targets in these samples, given that (1) it offers self-regulation assessment and behavior change tools via an integrated platform to a wide array of populations, and (2) content within the platform can be quickly modified as needed to better impact targets. This is the fourth and final phase of a study that aims to identify putative mechanisms of behavior change to develop an overarching "ontology" of self-regulatory processes. This trial builds on NCT03352713.

Obesity, defined as BMI> 30kg / m2, is a major public health problem, with devastating medical and psychological consequences. 30% of obese suffer from BED type of eating disorders. The optimal treatment of obesity remains bariatric surgery, failed in 20% of cases. Many arguments are in favor of the involvement of the reward circuitry, with the central role of NAc in the pathophysiology of BED and obesity. The recent application and effectiveness of DBS (Deep Brain Stimulation) in refractory psychiatric disorders suggest that DBS may be of interest in treating obesity and BED with potential target for the NAc. This project propose to study fMRI activation of the reward system in response to food stimuli to better direct the DBS targets. This is a pilot study to define indication criteria based on fMRI to obese BED patients are potential candidates for treatment with DBS.
