The syndrome of anorexia-cachexie, which accompanies numerous cancers is a major comorbidity which compromises the forecast of these patients. Several cytokines pro-inflammatory as interleukines IL1 ß, IL6 or TNFa participate in the physiopathology of this syndrome at the man and the animal. Besides, it is now established that different neuronal populations, localized in the hypothalamus, are nerve centers of the control of the appetite and the energy homéostasie. However, there is not enough evidence of a direct action of cytokines on these neurones, suggesting the participation of intermediate molecules as chimiokines, inflammatory molecules produced in reaction to an immunological stress by gliales cells and acting directly on the surrounding neurones. The implication of chimiokines in the syndrome of anorexia-cachexie associated with the cancer thus seems very likely Among these, chimiokines " Monocyte Chemoattractant Proteins 1-3 " or MCPs represent obvious candidates because they are produced by multiple tumors. Furthermore, to the mouse, the intellectual expression of MCP1 is correlated in the anorexia led by peripheral injections of a bacterial by-product, the lipopolysaccharide (LPS). The investigators' main objective is to test at the Man's, in situation of cancer of the pancreas any confused stages, the degree of prédictivité of the chimiokine MCP1 towards the syndrome of anorexia-cachexie associated with the cancer. The investigator also suggest describing: i) the link between rate plasmatique of MCP1 and energy metabolism on one hand, physical composition on the other hand;; ii) the impact of the other chimiokines, particularly those of the family of the MCPs, on the anorexia-cachexie bound to the cancer, iii) the correlation enters their profile of expression plasmatique and the severity of the anorexia, the energy metabolism and the physical composition; iv) the same research on the other inflammatory factors plasmatiques, of nature different from chimiokines; v) the correlation between thin mass and anorexia; vi) the evolution of the chimiokines various and inflammatory factors after surgical treatment or chemotherapy with curative aim in 6 months.
By use of several questionaires, this study aimed at an investigation of the changes in motivation, symptoms, self-esteem and coping style in adolescent patients with anorexia nervosa.. The psychometric properties of the Anorexia Nervosa Stages of Change Questionnaire (ANSOCQ) and its relation to coping style and self-esteem were assessed. After a treatment period of nine months, clinical AN diagnosis and the body mass index (BMI) were re-assessed. Besides construct validity of the ANSOCQ, its predictive validity in terms of predicting the outcome of AN was assessed.
Fibroblast growth factor 23 (FGF23) is a recently discovered phosphaturic hormone produced by osteocytes. It is involved in phosphate-calcium metabolism (via its phosphaturic action and inhibition of 1,25-OH vitamin D). There are no published studies on the role of FGF23 in undernourished anorexic adolescents taking oral phosphorus supplements.
Anorexia is common symptom in cancer patients and is associated with increased morbidity and mortality. However timely detection with objective tools is necessary to establish the diagnosis of anorexia and to assess the magnitude of change over time. The anorexia pathophysiology is not clearly understood and treatment options are limited. Anecdotal historical benefits of smoking marijuana on nausea, pain and anorexia led to studies with marijuana and synthetic cannabinoids from Δ-9-tetrahydrocannabinol, the main active agent in marijuana. The endogenous cannabinoid system with its receptors CB1 and CB2 regulate appetite in four functional levels: (1) limbic system (hedonistic quality), (2) hypothalamus (appetite stimulant), (3) intestinal, and (4) tissue adipose. Nabilone, a synthetic analogue of THC approved in Mexico for nausea and vomiting induced by chemotherapy is also used in palliative care units for clinical improvement in increased appetite patients in terminal stages, however, there are no clinical trials demonstrating this benefit.
The study proposed in this protocol aims to document the physiological, subjective, behavioral, and neural effects of reduced environmental stimulation (floating) in patients with current or prior anorexia nervosa The primary aim of this study is to determine the safety of this intervention. Secondary aims including determining whether floating has an impact on symptom reports such as those related to anxiety and eating disorders.
The researchers plan to explore brain networks involved in emotion processing and learning using a brain scan and test meals. One core feature of Anorexia Nervosa (AN) is eating a small number of high-calorie or high-fat foods. By studying why individuals with AN are disgusted by food or other eating situations, the researchers will be able to understand more about the neurobiological pathways that lead to restricting food intake and food avoidance. This study also aims to find whether one of two short-term interventions (Interoceptive Exposure (IE); Family-Based Therapy (FBT)) affects connections in the brain and if the treatments affect food avoidance. IE is an intervention that helps reduce anxiety about eating. FBT is an intervention that motivates patients to eat through working with family to increase the value of eating and decrease the value of avoiding foods.
The investigators will examine whether compulsivity in those who score above-average (but below clinical cut-off) on an eating disorder questionnaire can be altered by 9 days of N-acetyl cysteine (NAC). N-acetyl cysteine has been shown to be of some benefit in individuals with other compulsive disorders, such as trichotillomania and addiction, so this research investigates whether a short period of time taking N-acetyl cysteine changes compulsivity, measured using cognitive tasks and questionnaires.
In the literature the use of olfactory dimension in the treatment of anorexia has not been verified experimentally. The investigator hypothesize that the therapeutic use of a dietary nature olfactory stimuli in anorexia nervosa promotes food recovery. The team propose a prospective study over a period of 12 months in which we use the Body Mass Index (BMI) as the primary endpoint of the state of anorexia nervosa patients.
The purpose of this study is to determine whether estrogen may help reduce fear of high calorie-density foods in weight-restored women with Anorexia Nervosa (AN).
