Active clinical trials for "Feeding and Eating Disorders"

The purpose of this study is to test the feasibility, acceptability and efficacy of two technology-based intervention systems (including an Advanced Digital Data Sharing (ADDS) with Coaches or a smartphone-based just-in-time, adaptive interventions (JITAIs) system) for improving treatment adherence, skills utilization and binge eating when used in conjunction with a self-help cognitive behavior therapy [CBT] delivered via a smartphone application [app]). The study is being conducted to test a novel approach to providing evidence-based treatment for binge eating without clinician support in a routine clinical setting.

This project includes a parallel group randomized controlled trial comparing two psychological treatments: 1) Exposure-based Family Therapy (IE) vs. 2) Family Based Therapy (FBT) for low weight eating disorders with 12 month follow-up. Primary outcomes are expected body weight and clinical impairment. Three mechanisms of change (Autonomous Eating, Non-Judgmental Body Awareness, and Extinction Learning) will be examined in a process mediation models of change.

Background: Over 60% of Canadians are overweight or obese and more than half have a history of a mental illness. The COVID-19 pandemic has made it difficult for people living with obesity to manage their weight even after undergoing bariatric surgery. These difficulties in combination with the stress of the pandemic can cause significant declines in mental health and well-being. Psychotherapy ("talk therapy") has been shown to be effective in helping to reduce mental health and disordered eating symptoms in patients managing obesity; however, there is limited data in the context of COVID-19. Objective: This study will examine whether providing a convenient and accessible telephone-based psychotherapy during and potentially after the COVID-19 pandemic will lead to better mental health and disordered eating-related outcomes in patients managing obesity after weight loss surgery. Hypothesis: Relative to the control group, those receiving psychotherapy will have lower mental health distress and eating disorder symptoms. Methods: Participants recruited from 4 weight loss surgery programs across Ontario will be randomly assigned to one of two groups: 1) Control (7 weekly non-structured check-in emails and access to online COVID-19 related mental health resources) or 2) Tele-CBT (a 7-session telephone-based cognitive behavioural therapy [a type of "talk therapy"] intervention focused on developing coping skills and specifically designed for weight loss surgery patients). Participants will complete measures of mental health distress, eating behaviours and a psychological distress scale prior to and immediately following the intervention. Implications: If Tele-CBT is found to improve post-pandemic mental health distress and eating behaviours, it could be routinely offered to patients with other chronic medical conditions as a resource to help manage psychological distress and mental health concerns emerging during and after the COVID-19 pandemic.

This is a randomized, double blind, placebo-controlled study of the effects of transdermal estradiol versus placebo on cognitive flexibility, reward processing, and eating disorder pathology in hypoestrogenemic female adolescents and young adults (ages 14-35 years) with an eating disorder characterized by extreme dietary restriction and/or excessive exercise. Subjects will be randomized 1:1 to 12 weeks of transdermal estradiol with cyclic progesterone or placebo patches and cyclic placebo pills. Study visits include a screening visit to determine eligibility and visits at baseline, 8 weeks, and 12 weeks. Study procedures comprise behavioral, neuroimaging, and endocrine assessments.

Gastrostomy is an intra-gastric nutritional enteral device that could be put in place by percutaneous technique under radiological guidance: allowing local anesthesia. However, there is no clear recommendation about local analgesia during this exam. Operator can chose Lidocaine with a short period of action, or Ropivacaine with a longer period of action. The association of these two drugs could enhance the analgesia post procedure. The main objective of this study is to decrease maximal pain felt during a twenty four hour stay, after a gastrostomy under percutaneous technique with radiological guidance.

Pathological out-of-control behavior is the core clinical symptom of Bulimia nervosa (BN). The study of its neural circuits and biological mechanism is very important to explore new intervention targets. Previous studies have found that the patients with BN have inhibitory control impairment, which may be the basis of uncontrolled binge eating and purging behaviors of BN. The study found that the cognitive decision-making dysfunction of substance addicts may lead to behavior solidification. At present, there is no related research on the cognitive decision-making model of BN. Previous studies of applicants have found that there is an enhancement in goal-oriented decision-making in BN, which may explain the binge eating and purging behaviors aimed at weight control. In addition, BN patients have obvious impulsiveness, and the individuals of BN often feel unable to control eating behavior , and experience obvious sense of out of control. The previous study confirmed that untreated BN patients were highly impulsive and had inhibitory control disorders. Inhibition and control disorder is one of the important pathogenesis of BN. Previous studies indicated that dorsolateral prefrontal cortex (DLPFC) and dorsomedial prefrontal cortex (DMPFC) were associated with aboved symptoms. In this study, the patients with BN were selected as subjects. A randomized, single-blind cohort study was designed to observe the effect of iTBS intervention of DLPFC or DMPFC on pathological out-of-control behavior. Combined with behavioral, neuroimaging and genetic techniques, the investigators focused on the function of the prefrontal lobe-striatum neural circuits dopamine system. By the objective markers of peripheral, brain imaging and behavior of BN, to provide new targets and ideas for the treatment of BN.

Eating disorders are a difficult to treat illness with significant psychological and physical sequelae. Cognitive behavioural therapy (CBT) has been the most researched and supported intervention for eating disorders. A particular version of CBT for eating disorders, CBT-E (Fairburn, 2008), has been the focus of much research over the past decade. Despite promising results from initial CBT-E trials these findings have not always replicated well and evidence points to high drop-out in real-world settings. Further, CBT-E is a resource-intensive intervention, which may contribute to poorer access to care. In an attempt to overcome some of these barriers related to CBT-E, Waller and colleagues (2018) recently developed a brief (10 session) version of CBT for non-low-weight eating disorders (e.g., bulimia nervosa and binge eating disorder), referred to as CBT-T. Preliminary evidence from a case series of adult patients suggests that CBT-T has similar efficacy to CBT-E with low rates of drop-out. However, further evaluation of this brief treatment is needed, including direct comparisons with CBT-E. Indeed, given that no comparison group was included in the initial case series, it is unknown whether either CBT-T or CBT-E may be superior to the other. Thus, the aim of the current project is to examine CBT-T's efficacy in comparison to CBT-E as it has been implemented at the eating disorders service at London Health Science's Centre, and to determine whether either intervention is superior based on treatment outcome and treatment drop-out. Non-low-weight individuals with eating disorders assessed at the Adult Eating Disorders Service will be eligible to participate in the study. The principle investigator is Dr. Philip Masson, Ph.D., C. Psych., 519-685-8500 ext. 74866.

This study will test the relative efficacy and effectiveness of the combination of naltrexone and bupropion (NB) medication as a treatment for binge-eating disorder (BED) in patients with obesity. This is a controlled test of whether, amongst non-responders to acute treatments, NB medication results in superior outcomes compared with placebo.

Eating disorders are severe mental illnesses, mainly affecting adolescent- and young adult women. The prognoses for eating disorders are relatively poor, and a large part of patients with these illnesses do not benefit from available conventional therapies. After decades of research into the causes of eating disorders, there is now compelling evidence for specific neuropsychological difficulties in patients affected by eating disorders. These neuropsychological difficulties are characterized by cognitive and behavioral rigidity (poor set-shifting abilities), as well as difficulties related to central coherence, planning and impulse control. Surprisingly, few therapies specifically target these difficulties, and they are rarely incorporated into treatment. Cognitive Remediation Therapy has shown promising results as an adjunctive therapeutic intervention for patients with anorexia Nervosa. The primary aim of this randomized controlled trial is thus to investigate the effect of Cognitive Remediation Therapy on neuropsychological function, symptoms of eating disorders and general mental health, quality of life and motor activity in women with both eating disorders (transdiagnostic) and these specific cognitive difficulties.

Binge eating disorder (BED) is one of the recently acknowledged eating disorders, with many theories underlying its pathology whether biological or psychological. From the biological perspective, changes in plasma ghrelin were hypothesized to have a major role in developing and maintaining the disorder, while from the psychopathological perspectives, abnormalities in emotion regulation were found in many patients. Since Dialectical Behavioral Therapy (DBT) is known to target emotion dysregulation, the main aim of this study is to assess the efficacy of DBT versus treatment as usual (TAU) in BED patients, and whether plasma ghrelin level will be affected after treatment in both arms.
