Gut Microbiome and Weight Gain After Smoking Cessation
Smoking CessationWeight GainInvestigating the effect of smoking and smoking cessation on the intestinal microbial composition and function. The investigators wish to determine whether the alteration in gut microbiome drives the significant weight gain seen in humans after smoking cessation, and find the mechanism by which the gut microbiome contributes to this phenomenon.
Effect of Moderate Weight Loss in Metabolically Abnormal Lean Subjects
Weight LossObesity is associated with a constellation of cardiometabolic abnormalities (including insulin resistance, elevated blood pressure and dyslipidemia) that are risk factors for diabetes and cardiovascular disease. Weight loss can improve all of the cardiometabolic abnormalities associated with obesity. Up to ~25% of lean people (Body Mass Index [BMI] 18.5-24.9 kg/m²) have many of the cardiometabolic abnormalities associated with obesity and are referred to as metabolically abnormal lean (MAL) people. However, the MAL phenotype is not well characterized, and it is unclear whether weight loss has beneficial metabolic effects in already lean people. Accordingly, the goal of this study is to: 1) carefully phenotype MAL people and 2) evaluate the effect of moderate (8-10%) diet-induced weight loss in MAL people. This will be investigated in 15 MAL (defined as having 2 or more of the following: intrahepatic triglyceride (IHTG) content ≥5.6%, glycated hemoglobin ≥5.7%, fasting plasma glucose concentration ≥100 mg/dl, 2-hr oral glucose tolerance test (OGTT) plasma glucose concentration ≥140 mg/dl, homeostatic model assessment of insulin resistance (HOMA-IR) ≥ 2.5) men and women. Only lean people who have a BMI ≥21.0 but <25.0 kg/m² will be asked to lose weight to avoid the risk that participants become underweight (BMI <18.5 kg/m²) during weight loss therapy.
Internet-Based Weight-Loss Program for Colorectal Cancer Survivors
Cancer SurvivorColorectal Cancer1 moreRATIONALE: A personalized Internet-based weight-loss program may help improve the quality of life for colorectal cancer survivors. PURPOSE: This randomized phase I trial is studying how well an Internet-based program works in helping colorectal cancer survivors lose weight.
Lean Body Weight-adjusted Rocuronium Dose and Intubation Conditions
Body Weight ChangesRocuronium1 moreIn this study, researchers wiil administer rocuronium, based on either the lean body weight or the total body weight in patients with body mass index (BMI) of 18.5 to 34.9 and compared the duration of action of the drug and its effects on tracheal intubation conditions and hemodynamic parameters..
Weight Abnormalities With Diet and Exercise Frequency in Egyptian Children With Cerebral Palsy
ObesityChildhood4 moreThe goal of this study was to find prevalence and correlations of different weight abnormalities and risk of abdominal obesity in a random sample of Egyptian children suffering from cerebral palsy. This cross- sectional study hypothesize the prevalence of weight abnormalities and risk of abdominal obesity in addition to positive correlations between weight abnormalities and number of exercise hours and frequency of meals in a random sample of Egyptian children suffering from cerebral palsy RESEARCH QUESTION: What is the prevalence of weight abnormalities and and risk of abdominal obesity in Egyptian children with cerebral palsy? Does the weight abnormalities correlates with number of exercise hours or frequency of meals in children with cerebral palsy?
Pre-sleep Protein Supplementation in British Army Recruits
Protein-energy; ImbalanceRecovery1 moreDietary protein has been shown to be important to support physical training. For occupational demands such as military training, new recruits often fail to meet the recommended protein intake during basic training (BT), with negligible amounts consumed in the evening. As such, individuals undertaking BT may require higher intakes than the general population.This study assessed the influence of a daily bolus of protein prior to sleep on performance adaptations, body composition and recovery in British Army recruits.
Meta-analyses of Nuts and Risk of Obesity
Body WeightObesity4 morePeanuts and tree nuts (almonds, pistachios, walnuts, pecans, pine nuts, Brazil nuts, cashews, hazelnuts, macadamia nuts) (herein referred to as "nuts") are a good source of unsaturated fatty acids, vegetable protein, fibre, and polyphenolics. Nut intake has been associated with reduced cardiovascular disease risk and claims for this association have been permitted by the FDA; however, intake of tree nuts is low in Canada. One of the barriers to increasing the consumption of nuts is the perception that they may contribute to weight gain more than other "healthy foods" owing to their high energy density. The evidence supporting this concern, however, is lacking. In a series of earlier systematic reviews and meta-analyses, we have shown that nuts improve glycemic control and metabolic syndrome criteria, findings which run contrary to any expected weight gain. However, it remains unclear whether nuts have an increasing, neutral, or even decreasing effect on body weight. To address the uncertainties, the investigators propose to conduct a series of systematic reviews and meta-analyses of the totality of the evidence from randomized controlled trials and prospective cohort studies to investigate the effect of nut consumption on body weight and adiposity. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing evidence-based guidelines and improving health outcomes by educating healthcare providers and patients, stimulating industry innovation, and guiding future research design
The Effect of Obesity on Endometrium in PCOS
Body WeightPolycystic Ovary SyndromeThe effect of Polycystic Ovary Syndrome (PCOS) with or without obesity has received a few attentions. There is a lack of evidence to whether the BMI affects the endometrial blood flow, which is necessary for implantation.
Endocrine and Neural Control of Eating in Women
Normal Body WeightObesityThe purpose of this study is to better understand how female sex hormones influence the food intake in the gut system through the release of satiety hormones as well as through central regulative mechanisms in the brain that subsequently contribute to the control of eating in healthy women at different stages of the ovarian cycle.
National Children's Food Survey II
Dietary HabitsLife Style1 moreThe overall objective of this project is to establish for the Republic of Ireland (ROI) a nationally representative database of food consumption in children aged 5-12 years to update 2003-04 data for this group and to complement more recent data on preschool children and adults. The survey will be comparable with existing survey data in ROI and with surveys in UK (GB & NI). The ROI database will be designed to address both nutrition and food safety issues of relevance to the development and implementation of public health policy, food safety risk assessment and to the needs of the food industry. In addition to detailed data on food consumption, data will be also be collected on body weight, lifestyle, including physical activity, determinants of food choice, urine, and composition of foods and food recipes. Food composition databases will be updated and restructured to facilitate future analyses of food ingredients, packaging materials, residues, contaminants, allergens, bioactives and microorganisms. Urine samples will be stored to facilitate future analyses nutrition and metabolic indicators, markers of food intake and for estimating exposure to food chemicals. Data will be analysed to estimate intakes of foods and nutrients and compliance with dietary recommendations, to establish the prevalence of overweight and obesity, to investigate physical activity patterns and compliance with guidelines, to identify psychological, social and attitudinal determinants of food choice and eating behaviour. Salt intake will be estimated from urine excretion. Findings will be disseminated to relevant stakeholders. The project will be carried out by a multi-disciplinary research team with strong linkages to related on-going research in food and health sciences.
