Filter by:Abnormal body composition with increased body fat mass and decreased lean body mass has been found in adults with Prader-Willi syndrome (PWS), contributing to reduced physical capacity and impairment. The aim of this study was to investigate whether progressive elastic band resistance training can improve physical motor performance and regional body composition in adults with PWS.
To evaluate the effectiveness of rhGH (Recombinant human growth hormone) injection for improving motor development in patients with PWS.
There have been some preliminary studies, primarily in animals, that suggest that exposure to some of the chemicals in our everyday environment, such as the chemicals found in plastics, may cause weight gain. It is not clear whether this also happens in humans, or whether decreasing exposure to these chemicals can improve success with weight loss when people adopt healthy lifestyle changes. The THRIVE Study is a 4-week group healthy lifestyle education program that is designed to determine whether: - changes in dietary habits and the types of personal care products used can decrease a person's exposure to chemicals in our environment that have been suggested to cause weight gain - whether any measurable changes in body composition (fat tissue vs. lean tissue) can be seen as a result of participating in the healthy lifestyle program.
This project will test whether a food response training intervention produces lasting body fat loss, use objective brain imaging to examine the mechanism of effect of this treatment and investigate the generalizability of the training to non-training foods, and examine factors that should amplify intervention effects to provide a test of the intervention theory. This novel treatment represents a bottom-up implicit training intervention that does not rely on executive control, prolonged caloric deprivation, and expensive clinicians to deliver, like behavioral weight loss treatments that have not produced lasting weight loss. If this computer-based response training intervention produces sustained body fat loss in overweight individuals, it could be easily implemented very broadly at almost no expense, addressing a leading public health problem.
The proposed research will follow healthy weight children who vary by family risk for obesity to identify the neurobiological and appetitive traits that are implicated in overeating and weight gain during the critical pre-adolescent period. The investigator's central hypothesis is that increased intake from large portions of energy dense foods is due in part to reduced activity in brain regions implicated in inhibitory control and decision making, combined with increased activity in reward processing pathways. To test this hypothesis, the investigators will recruit 120 healthy weight children, aged 7-8 years, at two levels of obesity risk (i.e., 60 high-risk and 60 low-risk) based on parent weight status. This will result in 240 participants: 120 children and their parents.
This study is a phase 2 randomized double blind 8-week treatment trial of intranasal OXT vs. placebo in 50 subjects aged 5 to 17 years with PWS in order to assess IN-OXT's affect on measurements of (1) eating behaviors (2) repetitive behaviors (3) weight and body composition (4) quality of life (5) salivary OXT and hormone levels (including ghrelin, pancreatic polypeptide, peptide YY, GLP-1, insulin, glucagon, testosterone, and estrogen). If superior to placebo, this data will add to the current knowledge that OXT is an effective treatment for hyperphagia as well as other symptoms of PWS. Funding Source- FDA OOPD
The aim of this research is to build systems that can recognize when people are stressed and then provide them with relaxation prompts in the moment to reduce their likelihood of being stressed, smoking, or overeating in the near future. Using these systems should help smokers be more effective in their attempts to quit by reducing their tendency to lapse when they are stressed or experiencing other negative moods or behaviors.
As populations become urbanized in Africa, the change to a more Westernized diet has been associated with rise in obesity and related metabolic syndrome diseases. The current study shows that in the West African Sahel, these replacement starchy staple foods have fast gastric emptying compared to traditional sorghum and millet foods; and implies that the latter could be beneficial in lowering glycemic response, providing energy from a meal over a longer time, and providing a satiety effect. Knowledge of this attribute of sorghum and millet foods could be useful to improve their image in West African cities to increase their consumption and to improve markets for local smallholder farmers.
The purpose of this study is to examine the psychological benefits of chronic exercise as well as the effects of exercise training on eating behaviors and stress-induced overeating in overweight and obese women. Participants will be randomized to an 12-week exercise condition or a delayed exercise condition. Assessments will occur at baseline, 6 weeks, and 12 weeks and will include answering surveys in real-time using smartphones, several assessments of eating behaviors and dietary intake, and questionnaire measures of factors which could mediate the relationship between exercise and eating. Participants will be compensated for completing assessments and for adherence to the exercise protocol.
There is no specific treatment for core symptoms of PWS. Regarding behavioral and psychiatric symptoms (hyperphagia, imulsivity and self-mutilations), one of the only drug options consists in antipsychotics, that are not efficient and might be responsible for a worsening of the weight gain (major issue in PWS). An alternative therapeutic approach for behavioral disturbances has been suggested by some authors with topiramate (Epitomax®), an antiepileptic drug that can be used as a mood stabilizer and anti-impulsive. In addition, topiramate is used as a treatment for eating disorders because it induces loss of weight and appetite. This last effect might be useful in the case of SPW. Except for some clinical case reports, the investigators only found one open study for topiramate in SPW 8 patientssuggesting promising effects. There si however no placebo controlled study.. Objective: To evaluate the efficacy of topiramate (200 mg / d) on Eating disorders (E), self Mutilations (M), irritability and Impulsivity (I), metabolic status, and tolerance among of PWS patients. Methodology: This is a multicenter (out-patients in Toulouse, Reims, Nantes and Paris and in-patients in Hendaye) 8 weeks double-blind placebo controlled study . Subjects (n = 125 for 112 analyzable) all having PWS, aged 12 years-old and more should have any of the following symptoms: E, M and U (see above). All subjects will be randomly allocated into two groups one taking a placebo, the other taking topiramate (50mg / day initially, increasing up to 50mg per week 200mg / day). The population of analyzable patients in and out patient will be of equal size (n = 56). The inclusion period is two years.. Are excluded subjects with antipsychotic or mood stabilizer medication or topiramate. The primary endpoint will be the rate of responders, with response defined by obtaining a score of 1 or 2 on the CGI improvement after 8 weeks of treatment Other assessments, secondary endpoints : - Clinic: Weight / Size / Self-injury behavior (french Echelle des Conduites Auto et Hétéro Aggressives, ECAHA)) - Psychometric: C-SHARP and A-SHARP / Conners (Impulsivity) / Dickens (Eating behavior for PWS) - Organic: NFS, serum electrolytes, creatinine, ammonia plasma, serum bicarbonate, AST / ALT / GGT, ghrelin, fasting glucose, lipid profile and insulin, leptin, TG and HbA1c. - Side effects of topiramate: SAPS / SANS and BPRS (hallucinations), anxiety scales and laboratory tests.
