Active clinical trials for "Obesity"

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.

The main objective of this trial is to assess the clinical usefulness of thyromental height test (TMHT) in prediction of difficult intubation in obese patients scheduled for elective surgical procedures. The secondary aim is to evaluate usefulness of other commonly used predictive tests associated with difficult intubation in obese patients.

The main objective of the study is to assess the serum levels of progranulin and FAM19A5 protein in adults with metabolic syndrome.

Obesity is defined as abnormal or excessive fat accumulation. It is a complex disease with multifactorial etiology. Although the prevalence of obesity is generally greater in elders and women, obesity rates have increased in all ages and both sexes in recent years. Obesity or overweight also has a higher risk of diabetes, metabolic syndrome, dyslipidemia, hypertension, hyperuricemia, gout, osteoarthritis, cardiovascular disease, coronary artery disease, breast cancer, endometrial cancer and colorectal cancer. The body mass index (BMI), calculated as weight in kilograms divided by the square of height in meters, is widely used to define overweight and obesity in clinical studies. In Taiwan, subjects with BMI between 24 and 27 were diagnosed of overweight, and those with BMI over 27 were diagnosed of obesity. Chinese herbal medicine (CHM) was widely used in the treatment of obesity. The main purpose of CHM treatment is to promote metabolism, suppress appetite and block intestinal digestion and absorption of fat. Since there are various adverse effects of anti-obesity medicines, and there are surgical complications including infection and anastomotic stenosis, patients may seek CHM for losing weight. Many studies have indicated the efficacy of single herb in the treatment of obesity. Currently, the amount of computerized clinical data is increasing rapidly with the adoption of electronic medical records. The study is expected to collect the medical records, including the data of body weight, related side effects and biochemical data of each individual. By comparing the change of related data before and after CHM treatment, we could evaluate the efficacy of CHM in patients with obesity.

Physical activity is mainly considered and use for its impact on energy expenditure in the treatment of obesity, and less is known concerning its indirect effects on energy intake. The aim of this work is to clarify the impact of an acute bout of exercise, depending on its intensity (high versus low), on the following energy intake and nutrient utilization, in obese and non-obese boys and men.

MOPS: Mannheim Obesity Pilot Study Introduction: Obesity is a central feature of the metabolic syndrome. With increasing prevalence of overweight and obesity, the incidence of WHO III° obesity will further augment. In this subset of obese patients, metabolic complications and cardiovascular risk are major clinical issues. Epidemiological data show that with increased BMI mortality rises (1). The SOS-Study demonstrated, for the first time, that bariatric surgery and consecutive weight reduction are associated with a decrease in cardiovascular and overall mortality. Significant mortality in this study was caused by cardiovascular events and cancer. Metabolic Syndrome - MS - Despite varying definitions of the metabolic syndrome, obesity is one of its central features. Depending on the definition used, it can represent an obligate criterion (IDF) or a facultative parameter (WHO and ATP III). Even though not obligate, extreme obesity is a central risk factor for most other parameters of the metabolic syndrome. Endothelial dysfunction -ED- represents the initial step of atherosclerosis (3). An appropriate measurement is the evaluation by retinal analysis. Epidemiological data demonstrate increased cardiovascular risk with retinal vessel pathology (4).

This study tests the hypothesis that exercise training can confer additional benefit to patients in weight-loss programs in the form of improvements in either metabolic or vascular parameters or both. Patients will be randomized to either diet plus conventional physical activity or diet plus a planned exercise training. The interventions will be carried out until the patients lose between 5% and 7.5% of their initial weight. At entry and at the end, all subjects will be evaluated for outcomes such as blood glucose, lipid profile, insulin, c-reactive protein, fibrinogen, vascular reactivity (doppler ultrasound) and total and abdominal visceral fat (CT-scan). Both groups will be compared.

The purpose of this study is to determine whether walking exercise after dietary treatment of obesity is associated with a decrease of the daily spontaneous physical activity and\or with an increase of the time spent in sedentary activities. Our hypothesis is that the practice of walking as an exercise during the phase of weight stability following the dietary treatment of obesity leads to a reduction of spontaneous physical activity and\or to an increase in the time spent in sedentary activities.

The aim of our study is to suggest possible underlying mechanisms for the observed clinical differences in disease severity and behavior of overweight and obese patients with crohn's disease(BMI > 25 kg/m²)as compare to non-obese crohn's patients with a normal or low weight ( BMI ≤ 25) by measuring metabolic\nutritional variables and cytokine levels.

The Nordic Diet is a dietary pattern rich in traditional Nordic foods, including berries, grains, and fatty fish common in northern Europe. Studies have shown a protective effect of the Nordic Diet on cardiometabolic risk factors, however only select clinical practice guidelines for the management of diabetes (i.e. Diabetes Canada) recommend this dietary pattern. To support the update of the EASD clinical practice guidelines for nutrition therapy, the investigators propose to conduct a systematic review and meta-analysis of prospective cohort studies and clinical trials to investigate the association between the Nordic Diet, cardiometabolic outcomes and cardiovascular disease incidence and mortality. 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.
