INTRODUCTION: The high prevalence of metabolic syndrome (MS) in Spain requires additional efforts for prevention and treatment. OBJECTIVE: The study RESMENA-S aims to improve clinical criteria and biomarkers associated with MS though an integral therapy approach. METHODS: The study is a randomized prospective parallel design in which is expected to participate a total of 100 individuals. The RESMENA-S group (n = 50) is a personalized weight loss (30% energy restriction) diet, with a macronutrient distribution (carbohydrate / fat / protein) of 40/30/30, high meal frequency (7 / day), low glycemic index/load and high antioxidant capacity as well as a high adherence to the Mediterranean diet. The control group (n = 50) is assigned to a diet with the same energy restriction and based on the American Heart Association pattern. Both experimental groups are under dietary and psychological control during 8 weeks. Likewise, for an additional period of 16 weeks of self-control, is expected that volunteers will follow the same pattern but with no dietary advice. RESULTS: Anthropometrical data and body composition determinations as well as blood and urine samples are being collected at the beginning and end of each phase. This project is registered at www.clinicaltrials.gov with the number NCT01087086 and count with the Research Ethics Committee of the University of Navarra approval (065/2009). CONCLUSIONS: Intervention trials to promote the adoption of dietary patterns and healthy lifestyle are of great importance to identify the outcomes and nutritional mechanisms that might explain the link between obesity, metabolic syndrome and associated complications.

the Objective: [corrected] of this article is to review biomarkers that have been suggested in recent years as the link between inflammation, obesity and associated co-morbidities, as well as some questions that yet remain unclear. Increasing evidence indicates the important role of inflammation in the etiology of major public health problems. In the last years, several studies have proposed that obesity might be a inflammatory disorder. In addition, oxidative stress has been suggested as a potential inductor of inflammatory status and susceptibility to obesity and related disorders. Several biomarkers are being suggested as the link between obesity, insulin resistance, cardiovascular disease and metabolic syndrome, such as tumor necrosis factor alfa, interleukin-6 and -18, angiotensinogen, transforming grow factor beta, plasminogen activator inhibitor-1, leptin, resistin, C-reactive protein, serum amyloid A, sialic acid, fibrinogen, markers of endothelial dysfunction (von Willebrand factor, ICAMs, VCAMs), complement factor 3, haptoglobin, Zinc-alpha2-glycoprotein, eotaxin, visfatin, apelin, alpha1-antitrypsin, vaspin, omentin, retinol binding protein 4, ceruloplasmin, adiponectin and desnutrin. Some of this biomarkers are good predictors of cardiovascular risk (plasminogen activator inhibitor-1, sialic acid, fribrinogen, complement factor 3, C-reactive protein), adiposity (leptin, visfatin, resistin, haptoglobin) and/or insulin resistance (sialic acid, C-reactive protein, plasminogen activator inhibitor-1, von Willebrand factor). However, it is currently unclear the role of many of them concerning inflammatory processes in humans, as well as the factors involved in their regulation. [ABSTRACT FROM AUTHOR]
