Filter by:Multimorbidity, the co-occurrence of several chronic conditions, is a growing phenomenon that poses new challenges for clinicians and researchers. The association between a mental health disorder and a physical health disorder represents a particularly frequent subtype of multimorbidity and is associated with greater severity and higher consumption of care. It is essential and urgent to explore the specific pathophysiology of this subtype of multimorbidity in order to develop adapted therapeutic strategies. Psychiatric disorders, such as mood disorders, anxiety disorders, attention deficit disorder and binge eating disorder, are common in people with obesity. For example, although most of these disorders may improve after bariatric surgery, some components of these disorders, such as emotional dysregulation and impulsivity, need to be addressed as they appear to be involved in the development of addiction and suicidality after bariatric surgery. Therefore, screening and vigilance of these risks appear increasingly necessary. To address this challenge, the BariaPsy databank aims to explore the screening of certain mental health disorders frequently observed in adults with obesity through an innovative approach that explores behaviors in the form of dimensions. It will help clinicians to quickly identify markers of certain disorders, thus helping them to further investigate the problem and provide personalized resources to their patient.
One-in-four Canadians will be diagnosed with an abnormal heart rhythm called atrial fibrillation (AF) in their lifetime. This is expected to double by 2050, owing to an aging population and increased age- and health behaviour-associated AF risk factors (e.g., poor cardiorespiratory fitness, Type II diabetes, hypertension, and obesity). AF is associated with an increased risk of severe health outcomes including stroke, heart failure, dementia, and death. Nearly three-quarters of people with AF also have obesity (excess body weight). According to research, people with obesity that lose approximately 10% of their body weight can experience relief from uncomfortable AF symptoms. Losing weight may even help people return to a normal heart rhythm. Cardiac rehabilitation (CR) is a proven way to help people with heart disease live longer, healthier lives. So far, research has not shown whether CR helps improve the abnormal heart rhythms seen in AF. This may be because CR programs usually do not offer specific help with weight management. Therefore, adding behavioural weight-loss treatment (BWLT; group classes to change thoughts and behaviours to encourage weight loss) to CR programs may help people with AF and obesity experience relief from their symptoms. This randomized controlled trial will assess whether the combination of an AF-specific 'small changes' BWLT and traditional CR results in a greater proportion of patients with AF and obesity achieving ≥ 10% body weight loss compared to patients who receive standard care (traditional CR alone). Traditional CR consists of participating in exercise sessions, supervised by health professionals, twice per week for 12 weeks. In addition to traditional CR, patients that are randomized to receive BWLT will attend 12 weekly online group therapy classes to learn strategies from psychology to help encourage weight loss. The investigators will collect data pertaining to weight, AF burden, physical activity, and disease-specific and generic patient-reported outcomes. This information will determine if taking CR+BWLT helps patients with weight loss and AF symptoms. Further, it will help efforts to provide effective treatment to patients with AF to help participants lose weight and reduce or eliminate AF symptoms.
In order to evaluate the difference in beta cell mass in patients with and without hyperinsulinemic hypoglycemia after Roux en Y gastric bypass (RYGB) investigators aim to compare quantitative PET imaging of the pancreas between these patient groups. These highly relevant data will provide investigators with more information on the possible role of beta cell mass in the mechanisms of hyperinsulinemic hypoglycemia bariatric surgery.
This study will evaluate the effectiveness of the Bright Bodies intervention in improving body mass index (BMI) among 7-13 year-old children with obesity simultaneously with the impact of the implementation strategy on adoption, reach, fidelity, cost, and maintenance of the intervention in three heterogenous settings serving patients disproportionately affected by obesity.
The purpose of this study is to determine the effectiveness of mobile health applications in improving health outcomes and type II diabetes outcomes in type 2 diabetics. This study will involve a 6-month long commitment where participants will be expected to weigh themselves every morning, at the same time, and check their blood glucose readings daily before and after meals for at least three meals in the day.
This study is intended to investigate safety and feasibility of a new weight loss technique called 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 obese participants by means of argon plasma coagulation (APC) in combination with waterjet submucosal injection using HybridAPC. As primary endpoint the % total body weight loss (TBWL) will be determined as body weight difference at the final 6 months FU 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 6 months to assess the outcome of the GMA procedure.
More than 84 million - or 1 out of every 3 U.S. adults - have prediabetes, a condition that if not treated often leads to type 2 diabetes within five years. Average medical expenditures among diabetics are about 2.3 times higher than expenditures for people without diabetes. Physical inactivity and elevated body mass index (BMI) are major risk factors for the disease. Sedentary behavior is becoming increasingly prevalent with the growth of a 'work from home' culture, most recently driven by the COVID-19 pandemic. Cross-sectional epidemiologic data report significant associations between high amounts of sedentary (sitting) time and prevalent cardiovascular disease and diabetes. In our pilot study of 15 subjects with sedentary office jobs, 6 months of sit-stand desk use resulted in a 23% improvement in insulin resistance, most substantial in those who decreased daily sitting by over 90 minutes/day. Additional improvements in vascular endothelial function and triglyceride levels were seen without any change in exercise activity, step counts, or body weight. These findings not only corroborate epidemiologic findings on this topic but suggest causality and warrant a randomized control trial. The investigators hypothesize that adult subjects at-risk for diabetes will improve insulin sensitivity, metabolic and vascular (endothelial) health with a sit-stand desk intervention at work (whether in the office or at home), in the context of a randomized, controlled trial. The investigators will randomize 198 sedentary office workers with a BMI≥25 at risk for type 2 diabetes mellitus in a 1:1:1 ratio of three groups: (a) sit-stand desk intervention targeting 2 hours standing per day; (b) sit-stand desk intervention targeting 3 hours standing per day; or (c) control arm over 6 months. The block randomization design will allow for important dose-response analyses. The investigators will objectively quantify standing time, sedentary time, sedentary bouts, daily steps, and exercise activity times using a compact and re-usable accelerometer that adheres to the subject's thigh. This will provide objective assessments of activity levels and sedentary times for 7 full days each at baseline, 3 and 6 months. The device is equipped with an inclinometer to classify posture (sitting verses standing).
The retrospective cohort study will compare the prevalence of sarcopenia and associated factors between older patients who have undergone bariatric surgery and older patients with obesity without previous bariatric surgery.
Obesity is the main risk factor for the development of chronic-degenerative diseases in Mexico. Due to the difficulty of treating obesity, prevention is urgently needed. The holidays are the festive period with the greatest impact on adult body weight. Evidence from observational studies has shown that more than 50% of the annual weight is gained during this period. However, few preventive interventions have been carried out worldwide. The present work will evaluate the efficacy of the Watch your Weight During Holidays Program on the prevention of weight gain during 8 weeks in comparison with the control group in Mexican adults. The study will be a randomized clinical trial. It will have two intervention groups: 1) Watch your Weight During Holidays Program and 2) Control Group (minimal intervention). Weight, height, body mass index, waist circumference, kilograms of body fat, fat mass index, cm2 of abdominal fat, blood pressure and perception of health-related quality of life will be measured in 64 volunteers, at the beginning and after 8 weeks of participating in Watch your Weight During Holidays Program. For comparisons between groups, Student's t-tests or Mann-Whitney's U-tests will be performed, according to the type of sample distribution. The primary variable of the study will be the change in body weight. The secondary variables will be the change in body mass index, waist circumference, kilograms of fat mass, fat mass index, cm2 of abdominal fat, blood pressure and aspects of perception of quality of life related to health.
This study is being done to assess the feasibility and acceptability of a meal delivery intervention among low-income postpartum women with obesity.
