Active clinical trials for "Obesity, Abdominal"

Metabolic syndrome including increased body mass index or waist circumference is known to be a risk factor of cardiovascular disease. However, the relationship between body mass index or waist circumference and clinical outcome after cardiac surgery has not been fully elucidated.

We aimed to risk faoctors for GERD and association between visceral obesity, plasma adipoline(leptin, adiponectin, IL-6, TNF-α)and development of reflux esophagitis in healthy Koreans.

Sugars have been implicated in the epidemics of overweight and obesity. This view is supported by lower quality evidence from ecological observations, animal models, and select human trials. Higher level evidence from controlled trials and prospective cohort studies has been inconclusive. Whether sugars contribute to weight gain or increases in adiposity independent of their calories and whether important food sources of sugars other than SSBs are associated with a higher risk of overweight and obesity or weight gain remain unclear. To address the uncertainties, the investigators propose to conduct a series of systematic reviews and meta-analyses of the totality of the evidence from controlled trials and prospective cohort studies to distinguish the contribution of fructose-containing sugars and important food sources of sugars (SSBs, fruit, 100% fruit juice, cakes/sweets, yogurt, cereals, etc) from that of energy in the development of overweight and obesity. 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

This study aims to explore the determinants of cognitive impairment among Indonesian geriatrics in an Old Age Home.

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.

The principal aim of the present study is to analyze adiponectin, omentin-1, apelin and visfatin plasma levels in patients with and without AF in an effort to identify their potential role in the development of AF.

Comparison of the prevalence of obstructive sleep apnea (OSA), measured by polysomnography in normal weight patients with central obesity by body mass index (BMI) and waist hip ratio (WHR), with normal weight patients without central obesity by BMI and WHR. Evaluation of arterial stiffness and vascular age in normal weight patients with central obesity and in normal weight patients without central obesity. Determination of the exercise response characteristics in OSA patients.

The metabolic risks associated with obesity are closely correlated with central (abdominal), rather than a peripheral (gluteofemoral) fat pattern It has been shown that weight loss after bariatric surgery is followed by metabolic improvements. The amount of fat lost from each site may be independently regulated. Very scant information is found in the literature regarding the relative changes in different fat body compartments, and their effect on the improvement of the metabolic profile. In this study we define the absolute and relative changes in the different adipose tissue compartment after weight loss surgery

Recurrence and metastases after microwave ablation(MWA) of hepatocellular carcinoma(HCC) are the major factors that influence the survival. Obesity has been reported was significantly correlated with increased risk of developing HCC. In this study, we will analysis the association of multiple obesity index(waist circumference,waist-hip ratio and body mass index) with the prognosis of HCC treated by MWA.

Although it is frequently mentioned in the media that overweight and obesity have reached epidemic proportions worldwide and in this country, some Canadians are perplexed and sometimes confused about the role of obesity in diabetes and heart disease. In fact, the investigators even hear from time to time that there could be "healthy" obese individuals. In clinical practice, assessment of obesity as a risk factor for cardiovascular disease (CVD) remains a challenge as even some physicians are confused. However, studies conducted in our laboratory and by other research teams around the world over the last 20 years have clearly shown that body shape is more important than body size when evaluating the risk of overweight/obesity and that high accumulation of abdominal fat (excess belly fat) increases the risk of diabetes and cardiovascular disease (CVD). The investigators now need to better understand the link between excess belly fat and atherosclerosis (the thickening of artery walls by fatty deposits, also referred to as atherosclerotic plaque), leading to complications such as angina (chest pain) and myocardial infarction (heart attacks). Using non-invasive imaging techniques such as magnetic resonance imaging, the investigators therefore propose to examine the relationships between measures of fatness and of abdominal fat and the size of atherosclerotic plaque in large blood vessels of apparently healthy human subjects. This study is also a unique opportunity to look, for the first time, at the relationship between belly fat, blood sugar, several well-known risk factors for heart disease (cholesterol, blood pressure, cardiorespiratory fitness, etc.) and the size of atherosclerotic plaques. This research program should pave the way to the development of new improved preventive/therapeutic approaches focusing not on body weight but rather on abdominal fat and associated blood abnormalities which are predictive of the development of atherosclerotic plaques leading to the premature development of heart disease.
