Filter by:Patients referred to Calgary's Alberta Hip & Knee Clinic, while awaiting consultation with an orthopedic surgeon for hip or knee osteoarthritis, will be offered the opportunity to participate in a dietary counseling program with the goal of attaining weight loss prior to surgery. Those patients interested in participating in the program will be offered the opportunity to participate in the research trial.
This study is undertaken to explore in T2D, the effect of meal timing on serum induced SIRT1 and Clock Genes mRNA expression in cultured hepatocytes. Fasting serum samples were collected from T2D participants, following two different meal timing schedules, either a diet with large breakfast and lunch with small dinner Breakfast Diet (3Mdiet) or an isocaloric diet with 6 small meals evenly distributed along the day Allday Diet (6Mdiet). The researchers will use an ex-vivo/in-vitro approach in which cultured medium will be conditioned with the fasted human serum collected from the two groups of T2D participants at baseline, after 2 weeks and after 12 week of the diet intervention.
Obesity today has become one of the main public health concerns. As a consequence, different strategies have arisen to fight weight gain. One of the alternative strategies to increase the success of therapeutic approaches to weight loss is the increase in energy expenditure, through thermogenesis, regulated by the beige/brown adipose tissue (BAT). Studies have shown that beige/BAT has a strong correlation with body weight regulation. It has also been demonstrated that cold exposure activates beige/BAT. Recent studies, mainly in animal models, suggest that beige/BAT can also be activated by specific food and nutrients. Concomitantly, new dietary interventions, to treat obesity, have also been studied. One of these dietary interventions is the Fasting Mimicking Diet (FMD). Since FMD is high in unsaturated fat, and clinical trials have shown that FMD interventions reduced body weight and improved metabolic health, there is a possible association between this diet and the activation of beige/BAT. The aim of this is study is to investigate the effect of Fasting Mimicking Diet on the activation of beige/brown adipose tissue, in humans with overweight. This will be an open clinical trial with the duration of three consecutive months (three cycles of the FMD diet). There will be an FMD and a control group. The following data will be collected before and after the intervention, for each group: dietary intake and physical activity data, evaluation of beige/brown adipose tissue activation (Positron Emission Tomography - PET with fluoride-18-labeled fluorodeoxyglucose (18F-FDG) in combination with computed tomography - PET/CT scan, Thermal Imaging, BAT adipokines and genes related to BAT activity), basal metabolic rates and caloric needs (Indirect Calorimetry), anthropometric measures and body composition (DEXA scan), lipid profile and inflammatory markers. Data will be expressed as mean and standard deviation and the variables will be compared by Student's t-test or ANOVA, for repeated measures.
The purpose of this research study is to determine the effectiveness of nutrition tools to support weight loss among obese individuals. All participation will be based online and there will be no in-person visits. Participants will be given nutrition support tools for 6 months. Participants will be asked to report their weight and diet at the start of the study, and every month for 6 months during the study period. Participants will additionally be asked to report weight and diet at 12 months, 18 months, and 24 months after the start of the study. Total study duration will be 2 years.
A prospective, multicenter, open-label, post-approval study of the safety and effectiveness of ORBERA36 as a 12-month adjunct to weight reduction for obese adults (BMI ≥ 27 kg/m2 and BMI ≤ 50 kg/m2) or for pre-surgical weight reduction in obese and super-obese adults (BMI ≥ 40 kg/m2 or ≥ 35 kg/m2 with comorbidities).
The objective of this study is to estimate the proportion of the recurrent deletion Δ6-8 of the LEPR gene in the homozygous and heterozygous state in pediatric cases with severe and early ( before the age of 6) obesity (BMI ≥ IOTF-30) on Reunion Island.
The world prevalence of obesity in adult population in 2016 was 650 million while in Indonesia, it has increased from 14,8 percent to 21,8 percent in 2018. Obesity is an established risk factors for metabolic and non communicable- diseases. The purpose of this research was to assess the different effect on waist circumference, insulin resistance and oxidative stress marker between fasting (intervention) group and not fasting (control) group after 8 weeks 5:2 intermittent fasting (IF) among obese male workers.
The high prevalence of childhood obesity is a major public health issue, worldwide. Childhood obesity is associated with a high risk of cardiovascular events in adulthood, but recent studies also point out the development of cardiovascular complications in childhood or adolescence justifying the need for early detection and appropriate therapeutic management to prevent the development of more severe abnormalities. This project proposes to evaluate the myocardial function in a fine and comprehensive way (longitudinal, circumferential and radial linear deformations, and rotation / torsion mechanics) from the deformation imaging (MRI and high-resolution echocardiography), in obese adolescents following a lifestyle intervention combining diet and physical activity.
Low mobility is a mediator for poor outcomes of hospital care. Wearable devices will be used and 2-way texting via patient smartphones to monitor patients' physical activity during hospitalization with and without gamification to improve patient adherence to existing guidance on recommended activity. After discharge, investigators will assess patient care utilization (SNF, inpatient vs home rehab, ED visits, readmission) and conduct validated surveys on patient function at 30 days after discharge.
In the United States, the most significant risk factors for endometrial cancer (and EIN) are obesity and metabolic syndrome, given their high prevalence in this population. Given the high survival rate in early stage endometrial cancer, these patients, specifically those that are obese and have metabolic syndrome, are more likely to die of other causes. By treating an obese patient's endometrial cancer, one cause of death may be prevented but an important opportunity is missed to improve overall survival after cancer treatment. Concurrent laparoscopic hysterectomy and weight loss surgery is not an experimental procedure. This combined procedure has successfully been performed at our institution numerous times but there is a lack of data describing clinical outcomes and ideal patient selection. The goal of this study is to assess the feasibility of an expedited referral process for the obese endometrial cancer or EIN patient from her gynecologic oncologist to the Brigham Center for Weight Management and Metabolic Surgery. Secondary outcomes will include short-term and long-term obesity-related outcomes (i.e., better diabetes control, lowered cholesterol, lowered baseline blood pressure) as well as whether quality of life is improved post-operatively compared to preoperatively in concurrent surgery.
