Filter by:According to the World Health Organization, cardiovascular diseases (CVDs) are the number 1 cause of death globally. Systemic and local tissue inflammation is now recognized as a key etiological process leading to CVD. Hence, elevated blood levels of inflammation markers are classified among the well-established risk factors for the development of CVD. Among nutritional strategies to prevent and/or reduce chronic inflammation, long-chain omega 3 PUFA (LCn-3PUFA), notably eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have raised tremendous interest for their purported anti-inflammatory effects. Previous meta-analysis of randomized controlled trials (RCTs) substantiated the anti-inflammatory effect of LCn-3PUFA supplementation as evidenced by significant reductions in plasma concentrations of specific inflammation markers such as C-reactive protein (CRP) and tumor necrosis factor alpha (TNF-alpha). However, it is stressed that almost all of the reported RCTs have used a mix of EPA and DHA in various ratios, as EPA and DHA occur concomitantly and naturally in food (fish oils) and in most dietary supplements. Yet, several recent RCTs have recently been undertaken to test the hypothesis that not all LCn-3PUFAs are equal, at least when it comes to their anti-inflammatory effects. Accordingly, there is increasing interest and evidence for potential distinctive effects of DHA compared to EPA on systemic inflammation, raising the question: Is DHA a more potent anti-inflammatory nutrient than EPA? To formally answer this question, we will conduct a systematic review and meta-analysis of RCTs to assess and compare the individual anti-inflammatory effects of DHA and of EPA. The present work will be a pairwise and network meta-analysis focusing on RCTs comparing the effects of EPA and DHA on surrogate markers of systemic inflammation. The findings generated by these analyses will provide invaluable and timely comparative information on the specific efficacy of DHA and EPA as one of the key nutritional modalities for the treatment of chronic inflammation in high-risk men and women. This is important considering that LCn-3PUFA supplements are increasingly being used by the population and an ever growing market in the dietary supplements' industry.
This project offers the opportunity to obtain detailed measurements on the health of body composition, metabolic health, and intestinal microbial diversity in overweight adults; moreover to provide information about the effects of physical exercise on them. The aim of the research is to advance in the understanding of the mechanisms induced by physical exercise, which includes the measurement of nutritional parameters, clinical and biochemical biomarkers of hepatic/cardiometabolic health, as well as the application of differential proteomics technologies by means of Arrays of cytokines and intestinal microbiome, making this study a novel and pioneer in sensitive areas of primary health care in Latin America.
The purpose of this study is to explore the effects of an intervention designed to help increase physical activity and decrease screen time.
In obese patients the superficial adipose tissue works as an endocrine active tissue to express different cytokines, and multiple molecular pathways implied in the cross talking with different part of the human body, such as the cardiovascular system. To date, adipocytes and adipose tissue-derived macrophages and adipose tissue synthesize, and secrete several cytokines, and sirtuins. In this setting, the excess of body fat is linked to heart contractile dysfunction. All these pathways are differently expressed in obese diabetic patients as compared to obese non diabetic patients. Intriguingly, in diabetic obese patients the hyper-expression of inflammatory cytokines is associated to a hypo-expression of sirtuins. Furthermore, microRNAs (miRs) as miR 195 and miR 27 could be implied in the regulation of this complex cellular and molecular axis.Therefore, this molecular pattern in diabetic obese patients may correlate to altered myocardial performance, and to the development of heart failure disease. In this study authors will evaluate at baseline by peripheral blood samples and by the abdominal fat tissue, and than at 12 months of follow-up by perupheral blood analysis, the expression of cytokines sirtuins and miR 195/27 comparing pre-diabetics obese patients vs. non pre-diabetics obese patients.
The objectives of this study are to determine, in normal-weight and overweight subjects the effect of: Primary: oatmeal containing 4 g oat β-glucan on food intake at a subsequent meal compared to Cream of Rice cereal. Secondary: (i) oatmeal containing 2 g oat β-glucan on food intake at a subsequent meal compared to Cream of Rice cereal; and (ii) oatmeal containing 2g, 4g and 4g low MW oat beta-glucan on subjective appetite ratings, gastric emptying, postprandial responses of glucose, insulin, ghrelin and PYY levels compared to those elicited by Cream of Rice cereal. In addition, the relationship between amount, MW and viscosity of OBG and the primary and secondary objectives will be determined.
This randomized phase II trial will enroll overweight cancer survivors. Subjects in both groups will be educated to follow a diet pattern similar to what is recommended by the Dietary Guidelines for Americans and the American Institute for Cancer Research (DGA/AICR) but one group will also receive 18 ounces of lean beef for incorporation into a healthy diet. Subjects will be encouraged to exercise regularly and activity will be monitored throughout the study. Nutrition and exercise may help cancer survivors successfully maintain improved dietary patterns, body composition, and physical activity efforts and consumption of beef may favorably impact lean body mass and specific nutritional outcomes.
Behavioral obesity treatment produces clinically significant weight loss; for the greatest impact, it should be made available in the primary care setting where it can reach the many patients with overweight/obesity. The investigators developed a 3-month automated online behavioral weight loss program, Rx Weight Loss (RxWL), and showed that it produces clinically significant weight losses among primary care patients. The investigators' early efforts at pragmatic implementation of RxWL have been promising, and have shed light on challenges associated with implementation, and the need to study longer-term effectiveness. The investigators will therefore conduct a pragmatic study to improve the implementation and effectiveness of this behavioral obesity intervention delivered in routine and representative healthcare settings. The investigators are partnering with the Rhode Island Primary Care Physicians Corporation (RIPCPC), a large primary care network of 58 practices with 100 physicians and 16 nurse care managers. Using the framework for Effectiveness-Implementation Hybrid Designs, the investigators will simultaneously target effectiveness and implementation to maximize the public health impact of the research. Half of the 16 nurse care managers, and the practices they serve, will be randomized to either Basic Implementation (alerts generated using the electronic medical record [EMR] to direct eligible patients to RxWL), or to the Enhanced Implementation (alerts, clinician skills training to motivate and support weight loss, clinician dashboard with reports on patient progress and tools to facilitate patient engagement and behavior change). The investigators will test the hypothesis that the Enhanced Implementation will increase the proportion of patients directed to, enrolling, and completing the weight loss program. Because maintenance of weight loss is a critical problem, this project will also involve randomization of 600 patients with overweight/obesity and type 2 diabetes, hypertension, and/or hypercholesterolemia to the 3 month RxWL intervention followed by one of three maintenance conditions: (a) Control- 9 monthly online education sessions; (b) Monthly Lessons and Feedback- 9 monthly online video lessons teaching self-regulation with automated feedback on the self-monitoring record; (c) Refresher Campaigns- 9 monthly on-line video sessions, teaching self-regulation and providing two 4-week courses with novel strategies and behavioral challenges to improve long-term outcomes. The investigators will test the hypothesis that 12-month weight losses are better with Refresher Campaigns than Monthly Lessons and Feedback, and both are better than Control. Secondary outcomes include changes in weight, CVD risk factors, and medication use over a full 24 months. The project is significant and innovative because: it uses an empirically validated approach to obesity treatment that is integrated into the primary care setting, leveraging existing staff and EMR capabilities; it has a dual focus on improving effectiveness and implementation; it has a pragmatic design in partnership with a large primary care network that treats a diverse patient population; and it has potential to it provides a scalable, sustainable approach that can serve as a model for broader dissemination of obesity treatment intervention.

Obesity in children and adolescents has become a major public health problem in recent years. In Belgium, 20% of people aged between 2 and 17 are overweight and 7% suffer from obesity. While studies often associate this overweight with socio-economic level, other factors, such as health literacy (HL), may also play a role. Among adolescents, some studies have shown an association between the level of HL and the Body Mass Index (BMI). Our study aims to investigate the association between HL of adolescents and their BMI. This is a cross-sectional survey among 9 high schools in a medium city of Belgium, including 254 high school students aged between 12-17 years. Health literacy was assessed by the Health Literacy Measure for Adolescents (HELMA). Student's age, sex, weight, size and parental socio-economic status are gathered in the medical file during the medical examination organized by the schools after obtaining the informed consent of the students and their parents.
This study looks at a new study medicine for weight control in people with overweight or obesity. The aim of this study is to see if the study medicine is safe for people to take. The study also looks at how fast the body removes the study medicine. The participants will either get NNC0194-0499 (the study medicine) or placebo (a formula that looks like the medicine but does not have active ingredients). Which treatment the participants get is decided by chance. The participants will get 1 or more injections into the skin of stomach area once each week for 12 weeks. The study will last for about 4 to 5 months. The participants will have 18 visits to the clinic.
