Filter by:The existing scientific evidence from both in vitro and clinical trials supports the notion that polyphenols can modulate platelet function. Beyond being central players in haemostasis and thrombosis, platelets have crucial roles in the development of atherosclerosis, mediated through their interactions with monocytes and endothelial cells. Disturbed platelet function correlates with other risk factors, including hypertension and obesity, and the progression of cardiovascular diseases (CVD), postulating platelets as rational targets in CVD prevention. Thus, the effects of polyphenols on disturbed platelet function would contribute to their pleiotropic beneficial effects of on cardiovascular health. Aronia juice is a rich source of polyphenols including anthocyanins, procyanidins, phenolic acids and flavonols. However, there is no clinical evidence on the effects of aronia juice consumption on platelet function and related CVD factors. The purpose of this study is to investigate the effects of Aronia juice polyphenols on platelet function and other CVD risk factors in subjects with moderate CVD risk.
Obesity is a major risk factor for cardiovascular disease and diabetes. Weight loss is an important therapeutic goal for overweight and obese patients to reduce their risk of developing cardiovascular disease and diabetes. Liquid meal replacements (LMRs) are simple tools that may aid in weight loss and may improve weight-related risk cardiometabolic risk factors. There is a need to synthesize the evidence on LMRs and cardiometabolic risk to inform clinical practice guidelines. The authors propose to conduct a series of systematic review and meta-analysis of randomized controlled trials to evaluate the effect of LMRs on 4 areas of cardiometabolic risk: markers of adipsoity, glycemic control, established lipid targets, and blood pressure.
Despite advances in the prevention and treatment of type 2 diabetes, its prevalence continues to rise worldwide. There is a need for new modalities to improve metabolic control in individuals with type 2 diabetes and those who are overweight or obese and at risk for type 2 diabetes. Contrary to the concerns raised about the adverse role of fructose in metabolic health, various lines of evidence suggest that fructose and its epimers may improve the metabolic handling of glucose through inducing glycogen synthesis. Recent small trials in humans suggest that catalytic doses (=<10g/meal) of fructose and its epimers (allulose, tagatose, and sorbose) may reduce postprandial glycemic responses to carbohydrate loads (i.e., oral glucose tolerance test or a starch load) in people with and without type 2 diabetes. There is also limited evidence that these acute effects may manifest as longer term improvements in glycemic control. There is an urgent need to synthesize the evidence of the effects of fructose and its epimers on postprandial carbohydrate metabolism.
Nutritional intervention in overweight middle aged individuals with subjective memory complaints.
The objective of the study is to investigate the efficacy of motivational interview intervention with adolescent students at a school environment on the adhesion to a therapeutic plan to loose weight.
This research study will compare two weight loss programs that provide different recommendations for how to reduce your energy (or calorie) intake to achieve weight loss in an effort to determine if fixed calorie reduction or varied calorie reduction is more effective for weight loss.
The present study is a public health project with the aim to treat overweight in children 9-11 years of age. After the first consultation the children are randomized to either continue the treatment at The Child Obesity Clinic, Child Department or to have the following 2-3 consultations on distance with Lync. Last visit for all children is on the Child Obesity Clinic after approximately 12 months. Follow up after at least 1 years will be performed.
Consumption of sugar-sweetened beverages (SSBs) has been linked to rising rates of overweight and obesity. The most prominent mechanism to explain the link between SSBs and obesity is that liquid calories are not perceived by the body; thereby, promoting less satiety, less energy compensation and more weight gain than does the same energy consumed in solid form. This view is supported by pooled analyses of acute preload trials that have primarily measured food intake as the outcome. Though failure of short-term compensation has been observed with liquid calories, results from these acute preload trials should not be extrapolated to infer that liquid energy sources lead to weight gain over the long-term. To date, it is unclear whether liquid calories have differential effects than solid calories on body weight gain over the longer term. To increase clarity in this issue, the investigators propose to conduct a systematic review and meta-analysis from long-term controlled feeding trials to distinguish the contribution of liquid calories from solid calories on body weight over the long-term. The findings generated by this analysis will 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 present study is a randomized pilot study, overweight/obese adolescent and young PCOS subjects will be assigned into two groups: Taichi arm and control arm. Hormonal profile and metabolic profile will be determined.
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
