Cold Acclimation as a Modulator of Brown Adipose Tissue Function in Adults With Obesity
ObesityThis study will investigate the effects of at least 12 weeks of weekly cold water immersions (water temperature 18ºC) on BAT perfusion in individuals with obesity. BAT oxygen uptake and tissue perfusion will be measured using 15O-O2 and 15O-H2O PET-CT, at room temperature and after cold exposure. In addition, BAT glucose uptake will be measured using 18F-FDG after 2 hours of cold exposure and BAT NEFA uptake will be analyzed using 18F-FTHA at room temperature. To understrand the metabolic effects of BAT activation in individuals with obesity and how the cold water immersions affect the BAT perfusion in humans is critical for the development of new strategies to treat obesity and its comorbidities.
Parks & Pediatrics Fit Together
Pediatric ObesityImplementationThe proposed project will test an implementation strategy (the "TrailGuide") for delivering an existing model of pediatric obesity treatment ("Fit Together") that has demonstrated ability to meet published recommendations for improving health outcomes of children with obesity.
Endoscopic Gastric Mucosal Ablation as a Primary Obesity Therapy
ObesityAdiposityThis study is intended to investigate safety and feasibility of a new weight loss technique called endoscopic Gastric Mucosal Ablation (GMA) that does not require surgery, but can be achieved using an endoscopic procedure. Previous studies have suggested that weight loss after vertical sleeve gastrectomy (VSG) is partly due to the removal of normal stomach tissue suspected of having hormonal function. The study will investigate the minimally invasive treatment of obesity by means of argon plasma coagulation (APC) in combination with waterjet submucosal injection using HybridAPC. As primary objective total body weight loss (TBWL) will be determined as body weight difference at the 6 months follow up (FU) visit after the last treatment session in comparison to the body weight prior to the initial treatment. After signing the informed consent the doctor and research team will determine if the participant meets all requirements for this study. If a participant is confirmed to be a suitable candidate additional tests will be performed prior to the first application of GMA to assess the health status of the participant prior to treatment. During the screening and baseline visit the medical history and the medications of the participant will be reviewed. After the treatments the participants will be followed for up to 12 months to assess the outcome of the GMA procedure.

Using Technology to Investigate Lapses in a Weight Loss Program Among Individuals With Overweight...
ObesityWeight LossApproximately 70% of American adults have overweight/obesity, which increases risk of major medical issues and preventable death (Abdelaal et. al, 2017). Many individuals with overweight/obesity attempt to lose weight through behavioral strategies, e.g., adopting a reduced-calorie diet and/or increased physical activity. However, it is exceedingly difficult to consistently adhere to a reduced-calorie diet and high levels of physical activity; as such, most individuals attempting to lose weight via these methods experience repeated instances of non-adherence, i.e., dietary and physical activity lapses. These lapses are a core driver of weight loss failure, undermining individuals' ability to achieve weight control (Forman et al, 2017). As such, it is important to understand what predicts these lapses, which in turn allows for better lapse prevention. The current study proposes to measure these risk factors in an ecologically valid manner, i.e., in the moment they occur and in the context of individuals' everyday lives, using advanced technology. Specifically, the current study will use ecological momentary assessments (EMA; brief, repeated surveys delivered in one's natural environment, typically via a smartphone) and sensor technology (e.g., Fitbit and sensors on smartphone devices) to measure momentary risk factors of dietary and physical activity lapse, as well as the lapses themselves. Findings from this research project will lay the groundwork for a sophisticated just-in-time adaptive intervention (JITAI), a tailored, personalized intervention that targets momentary risk factors (e.g., cravings) via in-the-moment support, thereby reducing lapse occurrence and improving adherence to behavioral weight control prescriptions.
Integrating Community LITE Programme as an Online Family-based Intervention to Combat Childhood...
Pediatric ObesityChildhood obesity in Singapore is rising with a record prevalence of 13% in 2017 (1). Given that 70% of overweight children remain so into adulthood (2), this will further increase the public health epidemic of diabetes among Singaporeans. Early intervention is thus critical to improve the weight trajectory of overweight children and foster life long healthy lifestyle habits. Family-based interventions combining dietary, physical activity and behavioural interventions are currently recommended as the best practice in the management of childhood obesity in children younger than 12 years old (3-7). Our pilot study on family-based intervention in the tertiary setting demonstrated feasibility and short-term effectiveness. However, its outreach and sustainable results are limited. Currently, school-based screening, weight management clinics and community recreational facilities are operating in silos with limited effectiveness. Here, the investigators will integrate our family-based intervention into a school, clinic and community partnership to achieve an impactful and sustainable outcome for families with overweight children. The community Lifestyle InTervention for Everyone (LITE) program is a structured, group family-based multicomponent lifestyle intervention. Community LITE program will introduce various exercise programs within the family based online sessions to reduce perceived barrier and promote self-efficacy of community sports facilities to increase physical activity. Children have minimal control over their food and physical activity choices especially in current obesogenic environment (8). Parents are the most important influencers(9) to impose interventions for childhood obesity through parental practices and parenting style(10). Therefore, they are the main focus of the community-based intervention program.
Dietary Intervention in Obesity-related Glomerulopathy
ObesityGlomerulopathyObesity-related glomerulopathy (ORG) is a silent comorbidity associated with obesity whose incidence is increasing in parallel to the obesity epidemic. ORG is associated with serious health consequences including chronic kidney disease, end-stage renal disease, and increased mortality. Unfortunately, ORG has an absence of targeted therapy (except for the use of drugs blocking the renin-angiotensin system), and therefore the prognosis of this disease may be seriously compromised. Some previous studies have shown that weight loss could be effective to decrease albuminuria and reduce the declining in kidney function in subject with obesity. In line with this, in this study the investigators will evaluate the efficacy of two different dietary strategies for ORG, given the current lack of therapies for this condition. Thus, the investigators will conduct an open-label randomized controlled trial comparing a hypocaloric Mediterranean diet with a very-low calorie diet (VLCD), evaluating the efficacy on albuminuria reduction and changes in renal function. Also, the investigators will assess changes on body composition, blood pressure, markers of renal damage and inflammation, gut microbiota, and on renal ultrasound elastography.
Management of Childhood Obesity
Childhood ObesityPediatric ObesityThe significant increase in the prevalence of obesity can also be attributed to various social changes, in which the environment (political, economic, social, cultural), and not only the individual and his choices, takes a strategic place in the analysis of the problem and proposed interventions. The food environment can influence the choice and consumption of foods that promote obesity, such as ultra-processed foods (UPA). It is suggested that to intervene to effectively change behavior and eating habits, intensive interventions are needed that consider multiple levels that include the family, school, and community rather than one-off interventions that may not be effective in changing behavior and lifestyle. Regarding the family environment, parents or guardians can assist in the adoption of obesity-related behavioral patterns. It is known that the context of Primary Health Care (PHC) is ideal for actions to prevent diseases and promote children's health, since the PHC professional team is closest to the reality of life of the child, family, and community. We emphasize the importance of this study from the perspective of treatment of childhood obesity, in order to generate scientific evidence and practical subsidies for the implementation of interventions focused not only on the individual, but also in the context of the Unified Health System (SUS). The hypothesis of the study is that there will be a decrease in the consumption of ultra-processed foods (UPA) among children, aged 6 to 10 years, living with obesity and who are treated in primary health care. In addition to encouraging healthy habits such as physical activity and the consumption of in natura and minimally processed foods. The management of childhood obesity is one of the priority topics on the national agenda of SUS's food, nutrition, and health promotion policies.
