Study of Human Adipose Tissue (LOSHAT)
Weight ChangeBody7 moreThe investigators will study the influence of initial fat cell size/number and adipose function (in particular lipolysis) on weight development over very long time periods (years). By comparing investigations of fat biopsies or blood samples obtained at baseline, the investigators will determine the association between adipose morphology/function and changes in weight or development of metabolic complications (e.g. metabolic syndrome, glucose intolerance, type 2 diabetes, dyslipidemia and hypertension).
Addressing Post Cessation Weight Gain
ObesitySmoking CessationSome individuals smoke with the perception that smoking helps control body weight. Smokers gain an average of as much as 10 pounds in the months following smoking abstinence, with heavier and more-dependent smokers gaining more weight. T The Mayo Clinic Nicotine Research Program will randomize 100 nondiabetic, overweight or obese adult smokers to active lorcaserin or placebo for 24 weeks; all of the subjects will receive open-label varenicline for 12 weeks. The purpose of this study is to assess the efficacy of a 24-week course of lorcaserin for decreasing weight gain after stopping smoking.
Progesterone and Resting Energy Expenditure
MenopauseProgesterone1 moreThis study evaluates the effect of micronized progesterone substitution in the luteal phase on resting energy expenditure in women during menopausal transition.
Reducing Binge Eating to Prevent Weight Gain in Black Women
Binge EatingWeight Loss1 moreThe purpose of the proposed study is to pilot a 6-month, cognitive-behavioral binge eating intervention, Appetite Awareness Training (AAT) to reduce binge eating and prevent weight gain for Black women with a BMI > 25 kg/m^2 and with weekly binge eating episodes. Intervention participants will receive a 8-week group AAT intervention, and will also receive bluetooth-connected scales for daily weighing. Participants will also receive tailored feedback on self-weighing frequency and weight change. The investigators will follow-up with participants at six months.
Treatment on Iatrogenic Weight Gain and Dyslipidaemia Associated With Olanzapine
SchizophreniaOlanzapine is one of the most effective and best tolerated of the atypical antipsychotics, but it is also particularly associated with weight gain and metabolic problems. This study is being conducted by GW Pharma Ltd as a pilot study in order to determine the efficacy and safety of two medications GW42003 and GW42004 as a 40:1 ratio when combined with the subjects existing treatment of olanzapine in subjects with weight gain attributable to olanzapine treatment for functional psychosis. This is the first study to determine whether the study medications have a positive benefit for subjects on their cholesterol levels, body weight and other metabolic parameters, as well as a potential augmentation of the anti-psychotic effect of olanzapine. This is a multi-centre randomised, double-blind, placebo-controlled, parallel-group pilot study. There will be two groups of subjects (GWP42003 plus GWP42004 (40:1 ratio) and placebo), with a treatment duration of 6 weeks as well as a baseline period of variable length and one week follow-up. The two treatment groups will be randomised equally. In order to be eligible for enrollment in this study, subjects will need to be aged 18 years and above and be clinically diagnosed with functional psychosis and receiving olanzapine treatment for no more than 3 months with evidence of weight gain attributable to olanzapine treatment. Eligible subjects will enter the study at a screening visit (Visit 1) and commence a baseline period. Subjects will also be assessed at Visit 2 for further weight gain during the baseline period. The baseline period is flexible in length to allow time for this weight gain to be achieved and also for the olanzapine dose to be stabilised. If eligible the subject will be randomised into the 6-week treatment phase. There are a total of 6 visits in the study.
Improving Metabolic Parameters of Antipsychotic Child Treatment With Ziprasidone, Aripiprazole,...
Weight GainThe purpose of this study is to evaluate the relative risks and benefits of two approaches to the control of weight gain and other negative side effects in children and adolescents on 2nd generation antipsychotics (SGA): Healthy lifestyle instruction (nutritional and physical activity surveillance and advice) + continuation of current SGA; Add the diabetes drug, metformin + continuation of current SGA.
Effect of Rimonabant on Weight Gain and Body Composition in Adults With Prader Willi Syndrome
Prader-willi SyndromeThe purpose of this study is to evaluate the effect of rimonabant, a cannabinoid receptor-1 blocking drug, on the appetite, body weight, body fat and growth hormone level of subjects with Prader-Willi Syndrome (PWS). This will be a double blind placebo controlled clinical trial involving a total of 18 young adults aged 18 to 35 years with PWS. Patients will be divided in to the two groups of control and intervention, and treated with either placebo (inactive drug), or rimonabant 20 mg once a day for a total duration of 6 months. Body weight, fat distribution, objective and subjective assessment of the hunger, fasting blood sample for measurement of ghrelin and leptin (two hormones regulating appetite), serum lipids , IGF-1(growth hormone related protein), insulin and glucose concentrations will be measured upon enrollment, at 3 months, and at the end of the study. The proportion of body fat to muscle will be determined using a radiological technique, whole body dual-energy x-ray absorptiometry (DEXA) scan, and also by measurement of skin fold thickness, waist and hip circumference at the enrollment prior to the intervention, and at the end of the study.
Growth and Safety Clinical Trial on a New Infant Formula
Weight GainThe aim of this study is to assess age-appropriate growth of healthy infants fed a new infant formula. In this randomized, controlled trial, healthy, term, formula-fed infants will be randomized to one of two infant formulas: a standard, commercially-available infant formula for term infants or the new infant formula for term infants for 16 weeks. A reference group of human milk-fed infants will also be enrolled. This study is designed in accordance with Good Clinical Practice guidelines and the requirements of the Code of Federal Regulations, 21CFR106.96. This study allows caregivers to participate completely from the comfort of their own home.
Microbiome and Malnutrition in Pregnancy (MMiP)
Weight GainPregnancy11 moreNutritional status during pregnancy plays an important role in maternal health and birth outcomes. While few factors impacting nutritional status during pregnancy have been identified, studies of undernutrition in children have revealed a key role for the gut microbiome. Remarkably, studies examining the dynamics of the maternal gut microbiome before and during pregnancy and its impact on birth outcomes are limited. This study is being conducted to investigate how a mother's nutritional status and her gut microbiome during pregnancy contribute to the birth outcomes and health of her baby. The gut microbiome is the totality of microorganisms (e.g. bacteria, viruses, fungi) living in the gastrointestinal tract. This study will focus on married pregnant women 24 years and younger living in Matiari District in Pakistan. The focus is on younger women due to their vulnerability to undernutrition. Pregnant participants, and upon delivery, their newborns will be followed throughout pregnancy and for a year afterwards. Throughout this period, the investigators will collect stool samples, rectal swabs, blood samples, health assessments, nutritional and dietary assessments and birth/ labour details. The goal is to define the relationship between a mother's nutritional status and her microbiome dynamics during pregnancy and how they contribute to the birth outcomes and growth of her newborn. Investigators hypothesizes that alterations of the microbiota in the maternal gut (dysbiosis) is exacerbated by nutritional status or pathogen exposure during pregnancy. This impacts weight gain because of impaired nutrient absorption, and can lead to corresponding negative birth outcomes.
Effect of Dietary and Life Style Modification on Post Liver Transplant Obesity
Post Liver Transplantation Weight GainPost Liver Transplantation Obesity1 moreThis study is to assess value of providing classes about dietary and life style modifications to decrease or prevent weight gain, less occurrence or better control of weight gain associated disorders such as high blood sugar, hypertension, heart or brain vessels problems.Candidates for this study will be those who have got liver transplant within 6 months of their post transplant period.
