Filter by:The aim of the research project is to investigate the neurological, physiological and behavioral underpinnings associated with the development of anorexia nervosa in adolescents. The goal of the project is to enable new ways to both predict the course of the disease and to influence this process.
Anorexia nervosa (AN) is an eating disorder that can lead to severe medical complications. Kidney injuries are unknown in patients with extremely malnourished AN (BMI <13). The primary objective of the study is to evaluate the frequency and to determine the profiles of patients who may develop kidney injuries. The secondary objective is to evaluate the evolution of kidney injuries after a phase of refeeding. Guidelines for medical treatments and dietary intakes will be recommended to avoid severe or irreversible renal disease.
Amino acids (AAs) are crucial for protein synthesis, in influencing nutritional status, as sources of vital elements (e.g., nucleotides, neurotransmitters) and as signal molecules for the modulation of gene expression and epigenetic mechanisms. Data on the role of amino acids in underweight patients with anorexia nervosa (AN) are unknown. This study aims to evaluate whether a blend of essential amino acids (EAA) could influence the change in lean body mass (LBM) in patients with AN during weight restoration, treated with intensive inpatient enhanced cognitive behavior therapy (CBT-E). A total of 92 patients will be randomized to EAA supplementation or placebo supplementation upon admission to inpatient treatment. LBM, but also body weight, specific and general psychopathology, impairment assessment will be assessed at baseline and after 13 weeks of treatment.
Currently, Family Based Treatment (FBT) is the leading evidence-based, manualized treatment for adolescents with anorexia nervosa (AN). FBT emphasizes parental involvement in addressing disordered eating by supporting the child in eating and refeeding to achieve a healthy body weight and independent eating. Based on multiple RCTs, 50% of AN patients who receive FBT recover, and those who do not are more likely to develop a chronic illness. Research demonstrates that weight gain of less than 2.3kg (4.8 pounds) by week 4 of FBT predicts that 75% of adolescents with AN will not achieve weight restoration by the end of treatment. FBT works in part by reducing the avoidance of food and increasing the exposure to food triggers, like the treatment of anxiety disorders and obsessive-compulsive disorder (OCD). Thus, researchers postulate that anxiety may be a negative predictor of FBT treatment outcome in the early phase of FBT. In addition, elevated baseline anxiety has been shown to be associated with poorer outcomes at end of treatment and may also impact the likelihood of early response. To improve clinical response, we need to develop viable biological treatment targets (i.e., brain areas implicated in anxiety) that could be combined with FBT. Such targets can be defined by 1) initially targeting brain areas that mediate symptoms hindering treatment response (i.e., anxiety), and 2) looking at changes in brain chemistry and function. Thus, repetitive transcranial magnetic stimulation (rTMS) could be an alternative and promising treatment approach for adolescents with AN who do not respond to Phase 1 of FBT. Using rTMS, we can target the brain areas implicated in anxiety in people with anorexia and modulate that activity to reduce symptoms, and thus, facilitate response to FBT. Several studies have shown the rTMS to the right dorsolateral prefrontal cortex (DLPFC) is effective in reducing anxiety across a range of neuropsychiatric disorders. Therefore, it is possible that stimulating the right DLPFC could facilitate treatment efficacy of FBT in youth with AN. Additional explorations of the connections between, and neurochemistry of, the right DLPFC and those mediating emotion in the brain (e.g., amygdala) could aid in our understanding of the networks impeding effective treatment responses and allow for more tailored, precision targeting with TMS.
The BodyBabe studies aims to evaluate the perceptions that young mothers with anorexia nervosa (active or in remission) have of their own body and of the body of their child. The evaluations are carried out with self-assessment questionnaires and silhouette scales at three time points: D0 (during the stay at the maternity hospital), D15 (15 days after delivery) and M9 (9 months after delivery). The output expected from this study is to validate a questionnaire to help healthcare providers to adapt their care of women with anorexia nervosa during the pregnancy and the post-partum period.
The somatic complications as well as the suicidal risk make Anorexia Nervosa (AN) the psychiatric disease with the highest mortality rate: the standardized mortality ratio is higher than 4 and 1 in 5 patients with AN who dies has committed suicide. Approximately 20% of patients suffering from AN evolves into a chronic form without prolonged remission. These patients are at high risk of serious complications (somatic and psychiatric). The peak incidence of AN lies between 15 and 19 years: patients suffering from severe and resistant AN are therefore mostly young people. At present, there is no treatment for severe and resistant AN. New insights in AN pathophysiology revealed that AN patients develop a kind of "addiction" to thinness which contributes to weight loss despite negative consequences. In parallel, Deep Brain Simulation (DBS) is now widely performed for movements disorders with good results and low morbidity. DBS is also currently under investigations for other indications such as obsessional compulsive disorder or pharmacoresistant epilepsy. Some case series reported promising results of DBS for severe and resistant AN. The aim of this study is to investigate the safety of nucleus accumbens chronic stimulation for patients enduring severe and resistant AN. Secondary objective is to evaluate patient's acceptance of this new treatment.
164 patients will be recruited..Adult patients diagnosed with incurable solid tumors and CCAA who presented to Kasr Al-Ainy Center of Clinical Oncology and Nuclear Medicine (NEMROCK) - Kasr Al-Ainy School of Medicine - Cairo University will be randomly distributed into 1:1..82 will receive Olanzapine 5 mg daily at night and 82 patients will receive placebo for 4 weeks. Primary outcome is Change in loss of appetite score from day 0 to day 7 of treatment and secondary outcomes change in body weight, change in loss of appetite score..and change in quality of life
Patients with restrictive-type anorexia nervosa who are admitted to the hospital for feeding often urinate excessive amounts. Others have changes in the way that they handle acid and base. These issues prolong hospitalizations. Current data suggest that one hormone--named secretin--may control both urine output and how the body handles acid and base. This study will evaluate whether secretin levels are different in anorexic patients who urinate an excessive amount compared to those who urinate normal amounts. For this study, patients will have one extra blood draw before and after one meal during their hospitalization. The blood draw before the meal coincides with a standard of care blood draw. Also after the meal, subjects will be asked to provide one extra urine sample. Information from subject's medical records will also be used.
Reduction in appetite and/or food intake among older individuals is referred to as anorexia of aging (AOA, also known as Geriatric Anorexia). AOA is linked with myriad comorbidities associated with aging, contributes significantly to adverse health consequences in old age, and has been used as a predictor of morbidity and mortality. The overall aim of this study is to compare feasibility of body weight, body fat, body composition and activity assessments in elderly subjects in long-term care (LTC), nursing home, or assisted living facilities. This will be accomplished through the use of questionnaires in addition to devices that evaluate movement, body composition, and body weight.
This is an interventional study that will test the safety, tolerability, and efficacy of the Metabolic Diet, which was designed as a treatment for women with anorexia nervosa to remain weight-stable after they have been restored from low weight. Participants will be adult women with anorexia nervosa who have been recently restored to normal weight and adult women with no history of eating disorders. After enrollment, participants will start meeting weekly with a registered dietitian to implement the Metabolic Diet in their daily lives, and will receive medical monitoring for adherence, side effects, changes in metabolic or psychological parameters, and weight stability.
