Advancing Biopsychosocial Care Training Initiative

This project will compare two training approaches for US Preventive Services Task Force recommended obesity care in Federally Qualified Health Centers (FQHC) across four aims. Aim 1 compares patient-level effectiveness \[i.e., patient relative weight change and the proportion of patients who achieve clinically significant weight loss\]. Aim 2 compares reach (patient treatment utilization). Aim 3 compares primary care provider (PCP) referrals to USPSTF-recommended care at 12 (adoption) and 24 months (maintenance) and short- and long-term changes in provider obesity care competencies . Aim 4 compares implementation and service costs.

Weight Management After Cancer for Survivors in Rural Communities

This study is testing a new program called WeCan-Rural, designed to help breast cancer survivors manage symptoms and build healthy habits like eating well, staying active, and managing their weight. These changes may help lower the risk of heart disease after cancer treatment. The study will answer two main questions: * Can we successfully recruit and keep participants in the study, and will they find the program helpful and easy to follow? * Will people who join the program see better results in areas like weight, symptoms, diet, physical activity, and confidence in managing their health compared to those who receive standard care? Here's what participants will do: * Visit their clinic twice (about 12 weeks apart) to be weighed, have their blood pressure checked, give a blood sample, and complete a short walking test * Fill out online surveys about their health, diet, physical activity, symptoms, and confidence in managing their health * Be randomly assigned (like flipping a coin) to either receive the WeCan-Rural program or standard health information * If assigned to the program, attend 12 weekly one-hour video sessions on Zoom with a trained therapist

Weight Loss Management in Endometrial Cancer Survivors

This study is being done to understand how oncologists can engage a multidisciplinary team to help endometrial cancer survivors with obesity to engage in a weight management program and potentially start a weight loss medication. Obesity often impacts the future health and longevity of early-stage endometrial cancer survivors more than their cancer diagnosis. Patients will be referred to the KUMC OB/Gyn weight management clinic to discuss weight management options. * If patients decide to use medications for weight loss, then the study will collect data from their chart that is recorded as part of routine monitoring for patients on weight loss medications. * If patients decide not to use any medications, the study will monitor physical exam and lab data collected as part of their routine medical care. The study will also try to understand reasons why patients did or did not start using a weight loss medication.

Metabolic and Behavioural Effects of CONTRAVE as Potential Mechanisms of Weight Loss in Adults With Obesity

Obesity is a common chronic disease linked with increased risk for other illnesses and earlier death. Our team and others have shown that many bodily and psychological changes occur when individuals are on calorie-restricted diets. These changes might undermine dietary adherence and help to explain the relatively poor long-term efficacy of diets. These include increased appetite, increased food 'value' and 'wanting' that leads to overconsumption. Other factors include more sensitive sensory cues (e.g., smelling), higher food liking and craving, and a drop in resting energy expenditure (REE). REE has been shown to predict weight regain. The standard care for obesity may include the use of the weight-loss drug CONTRAVE®. The Federal Drug Agency (FDA) and Health Canada have approved this drug for weight management and obesity treatment. Although CONTRAVE® was designed to reduce appetite, food-related impulsivity and cravings, its mechanisms of action are unclear. In other words, the effects of CONTRAVE® on REE, executive function, and brain changes remain unknown in humans. A better understanding of how this drug works on the brain and body could lead to improvements in obesity management in the future. As such, the goal of this research is to study the effects of 4 weeks of CONTRAVE® (+ diet program) vs. control (placebo pill + diet program) on mood, body composition changes, biological/metabolic measures, and brain measures. Adults aged 18-64 with obesity will be randomized to one of two groups: diet + CONTRAVE® (CONTRAVE®, 20 participants) or diet + Placebo (Placebo, 20 participants). Both groups will be assigned the same study procedures for the entire study duration. The only difference is that Group 1 will receive CONTRAVE® while Group 2 will receive a placebo (non-medical) pill. The study design and intervention is as follows: Participants who meet all the telephone screening criteria will be invited to the Clinical EEG \& Neuroimaging Laboratory at The Royal's IMHR for an in-person screening and test-dose session. Participants who are cleared by the study physician, Dr. Pierre Blier, during the in-person screening will be enrolled in the 4-weeks trial. After the in-person screening visit, participants will attend two baseline testing visits (before starting the medication + diet program). The first will occur at the Behavioural and Metabolic Research Unit at the University of Ottawa. During this in-person visit, measures of body composition, resting energy expenditure, appetite, food craving, impulsivity, eating behaviours, taste and odour sensitivity, energy intake, and food preference will be collected. The second baseline visit (within a week of the first one) will occur at The Royal/IMHR. During this visit, participants will be asked to complete questionnaires. They will undergo an EEG recording while resting and performing computer tasks. They will also get a brain imaging scan, during which they are asked to rest and complete a computer task. Both testing sessions (University of Ottawa and Royal Ottawa testing sessions) will be repeated after four weeks of treatment. The section below provides further description and timing of these visits. As part of the treatment, you will receive an individualized dietary intervention with appropriate energy restriction from a registered dietitian at Dr. Judy Shiau's LEAF weight management clinic (called the 4-week BUDS program). The program involves weekly touch points with a registered dietitian and meal planning/coaching. The diet intervention will commence the same week as the start of the placebo/CONTRAVE®. During the 4-week intervention, participants will be asked to complete online questionnaires at various times.

How a Single Workout Affects Gut Bugs in Women With Different Fitness Levels and Body Types

This study aims to elucidate the differences in the gut microbiome functional activity and metabolome in adult premenopausal women with distinctive fitness levels and BMIs (with obesity, w/o obesity). The specific aims are as follows: * Aim 1: To examine the effects of acute aerobic exercise at 60-70% heart rate reserve (HRRmax) for 30 minutes bout on changes in the abundance of SCFA-producing bacteria and their functional downstream metabolic activity. * Aim 2: To examine the effects of acute aerobic exercise at 60-70% HRRmax 30-minute bout on changes in GM-released SCFA concentrations in stool and plasmatic metabolome.

Mitigation of Cardiovascular Disease Risks in Children With Extreme Obesity

The goal of this clinical trial is to learn if the drug semaglutide changes markers of disease risk as it relates to weight in children ages 12-15 years old who are obese (class 2 or 3). The main questions it aims to answer are: * How do the rate of weight loss, body mass index (BMI), body composition, heart structure and function, and exercise ability interact with one another in the study population at enrollment? * How do risk markers of disease change over the study in the study participants who are given semaglutides to help with weight loss? * Are there differences in the above factors between males and females and are there key factors to help improve the outcomes? Participants will be given semaglutide for this study. During the course of the study, participants will: * have two cardiac MRI scans OR two cardiac echocardiograms (one before starting semaglutide and one around 12 months after taking the drug) * have body composition and fitness levels assessed twice (before semaglutide and around 12 months after taking it) and have urine specific gravity (USG) measured * have extra blood drawn when labs their doctor orders are already being drawn (once at the beginning of the study, once around 6 months after enrollment, and once at the end of the study) * have follow up visits with the study doctor * be asked to take a pregnancy test if they are female and have started menstruation

Implementing Strategies for Eating Behaviour Modification Based on Portion Control

This is a pre-post intervention study designed to evaluate the feasibility of a self-applied weight management intervention based on portion control. A total of 40 healthy volunteers with overweight/obesity will take part in a 6-month intervention featuring 4 components: a portion control toolset; a manual including instructions for the use of the tools, dietary and activity recommendations, and behavioural strategies; a mobile app to motivate intervention engagement; and biweekly telephone support. The primary outcome will be Intervention adherence, assessed as the change in dietary energy density, meal nutrient composition and utilization of intervention components from start to end of trial. Other measurements (at baseline, 3 and 6 months from baseline) will include body composition, fasting biochemical parameters, inhibitory control, eating behaviour, portions size norms and acceptance of the intervention.

M4C Nutraceutical Intervention Human Health Effects Pilot

This 3 month pilot study will be an unblinded, convenience sampling, nutraceutical intervention trial. Twenty fasted subjects will undergo a baseline health assessment via a questionnaire, baseline clinical chemistries, blood lipids, dexa and impedence testing (to identify bone mineral density and body muscle/fat/water composition), and metabolite/novel biomarker testing through whole capillary blood, saliva, and urine collections. Assessments will be repeated every month (3 times after initial assessment) to cover a 3 month period. All measurements from each visit will be compared with baseline using paired t-tests or Chi square testing depending on variable. Power analyses are not included due to the pilot nature of the study. This pilot study will provide the necessary variability estimates for future trials.
