Diseases characterized by abnormal low and high body weight are common in the community and are associated with significant morbidity, mortality and health care related costs. Genetic, dietary, social and psychologic factors all play an important part in these conditions; however the central role of gastrointestinal (GI) function and the control of nutrient delivery to the small bowel has not been well described in health or disease. We propose that the GI response to feeding varies inversely with body weight. This hypothesis predicts that as body weight increases, the response to a given meal decreases in terms of motility, neurohormonal feedback, sensation and satiety. This provides an attractive explanation for why thin individuals stop eating after a small amount of food (i.e. limited gastric relaxation, rapid gastric emptying, powerful nutrient feedback with early satiety)and, conversely, why obese patients continue to eat even after nutritional requirements have been met (i.e. large gastric relaxation, slow gastric emptying, weak nutrient feedback with delayed satiety). This project will apply MRI and Breath Tests to assess GI motility, hormonal feedback, visceral sensation and satiety in patients with pathologically low (anorexia nervosa) and high (morbid obesity) body weight and in healthy, normal weight controls. Participants will include: Group A: normal weight, healthy volunteers (n=24: BMI: 18.5-24.9 kg/m2) Group B: patients with anorexia nervosa (DSMIV criteria and BMI: <16 kg/m2) B1: anorexia restricting type (n=12-20 over 2 years) and B2: anorexia bulimia type (n=20 over 2 years) Group C: patients with morbid obesity (BMI: 30-40 kg/m2) C1: obese (n=20 over 2 years) and C2: obese with DM type II (n=20 over 2 years). Two studies will be performed 1. Cross-sectional study: The effects of a test meal on GI motility, hormonal feedback, visceral sensation and satiety in healthy controls and in patients with anorexia and obesity 2. Longitudinal study: The effects of dietary treatment (i.e. weight change) on GI motility, hormonal feedback, visceral sensation and satiety in patients with anorexia and obesity
The investigators hypothesize that lung function would be adversely affected at the hypocaloric stage of adolescents suffering from anorexia nervosa.
UCAN is a research program funded by the National Institute of Mental Health and is part of the UNC Eating Disorders Program. UCAN aims to help couples work together in the treatment of anorexia nervosa. Couples participate in UCAN over a period of six months and return for follow-up treatment three months after the end of the original six-month period. Patients receive weekly individual therapy, monthly psychiatry consultations, monthly dietary consultations in addition to being randomized to one of two types of weekly couples therapy. Participation in UCAN can help participants gain new confidence in facing anorexia as a team and can help us understand how best to involve partners in the treatment of eating disorders.
This study will determine the importance and the level of physical activity among women with anorexia nervosa, both during inpatient treatment and 1 year after hospital discharge.
The objective of this research is to evaluate the efficacy of five different in-patient treatment modalities and predictive factors of outcome for anorexia nervosa. The primary hypothesis is that the different treatment types impact outcome of patients at discharge from inpatient treatment and at one year follow-up, even after adjustment for confounding factors (age, length of illness, number of previous hospitalizations, clinical state at intake).
Decreased bone strength is a common and serious medical problem present in many people with anorexia nervosa. Men with anorexia nervosa have lower levels of gonadal steroids such as testosterone. Low testosterone levels have been shown to result in low bone density. We are investigating whether bone mineral density and bone microarchitecture are abnormal in males with anorexia nervosa and whether supplementation with testosterone would improve both bone mineral density and bone microarchitecture.
The PICOWO research group in corporation with the University of Amsterdam (Artificial Intelligence) has developed a computer simulationmodel of eating disorders (Bosse, Delfos, Jonker & Treur, 2003). In a running Phd project we want to add ghrelin to the model. The idea for this current research is to collect clinical information about the functioning and (patho)physiology of ghrelin in patients with AN, so we can extend the simulation.
This study will examine the effectiveness of inpatient treatment for anorexia nervosa versus a sequenced treatment that transitions from higher intensity inpatient care to lower intensity outpatient care.
A 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.
