This clinical study is designed to evaluate the providing of a computational prediction engine for optimization of personalized nutrition Personalized recommendations for effective diet, lifestyle and activities based on the patient's parameters measurements and reactions will be provided on a bi-weekly basis, all Lab tests and dietician control will be performed twice a month.

The aim of the study is to describe an immune activation profile of people at risk of insulin resistance based on a wide range of markers which will allow easy identification of patients at risk.

Mindfulness based stress reduction offered to couples where one has metabolic syndrome to see if their stress is reduced as measured by bio markers and surveys

Evaluation of metabolic profile of users of hormonal and non-hormonal contraceptives during five years follow-up

This crossover study is designed to compare the gastric layering and rates of emptying and by inference rates of digestion of two different porridge meals prepared from either finely milled or flaked oats. On each of two study days, a total of 9 MRI scans will be taken, I baseline and 8 post meal, to assess gastric layering and emptying over three hours. Blood samples will also be taken periodically over the same period in order to determine changes in concentrations of circulating glucose, insulin and key gastrointestinal hormones. Participants will also be asked to complete a questionnaire at predetermined times to assess feelings of satiation.

Worldwide, the rising incidence of obesity has led to the identification of an obesity related syndrome, called metabolic. This syndrome is characterized by central obesity, hypertension, insulin resistance and altered lipid levels. Taking into consideration the rising incidence of obesity, anesthetists will more frequently encounter patients with metabolic syndrome, in their everyday practice. Moreover, the comorbidities that are related to the metabolic syndrome, increase the risk for perioperative complications. Therefore, strategies that will evaluate and modify the risk will be of great importance in the management of these patients, in order to maximize peri-anaesthetic and surgical safety. The aim of the study is to assess the incidence of metabolic syndrome and the impact of its presence on the outcome of patients undergoing elective laparotomy.

The aim of this study is to explore the microRNA profile in serum of women with Polycystic Ovary Syndrome and investigate the correlation between the microRNA profile and markers of metabolic syndrome.

Schizophrenia and bipolar disorders are major public health problems. The second generation anti-psychotic drugs have efficacy for both positive and negative symptoms and a favorable risk profile as far as movement disorders. However, these drugs are associated with clinically significant weight gain and metabolic effects. The underlying mechanisms of these side effects are unclear, however in our preliminary studies with schizophrenic patients on atypical anti-psychotic drugs, we found that weight gain and vitamin D deficiency was present in about 50% of this population. Given the considerable heterogeneity among the patients on atypical anti-psychotics and potential for weight gain in vitamin D-deficient states, we propose that patients with schizophrenia who gain weight on atypical antipsychotic medications are vitamin D-deficient. This hypothesis will be tested in patients with schizophrenia receiving second-generation anti-psychotic drugs for a minimum duration of 4 months. Specific Aim: We predict that the patients with schizophrenia, who gain weight with antipsychotic treatment, are vitamin D-deficient compared to the patients who do not gain weight. We will examine circulating levels of serum 25(OH)D, mRNA transcripts and protein expression of vitamin D receptor (VDR) and the enzymes, CYP24A and CYP27B, in the white blood cells of the subjects and correlate with BMI and the blood levels of leptin and adiponectin.

Childhood obesity is one of the most serious global public health challenges of the 21st century (Daniels et al., 2009). Mexico has the highest prevalence of obesity, (Secretaría de Salud, 2009); 34.4% of children and 35% of adolescents are overweight or obese (ENSANUT 2012). Obesity has major health consequences for children and adolescents; On the other hand, undernutrition as well has important deleterious consequences on children's health. Anything that disrupts energy balance may cause individuals to be underweight, overweight or obese. Fat has been considered an endocrine organ for some time (Elizondo, 2011). Recently, skeletal muscle has been shown to function as a peripheral endocrine organ by releasing myokines, (Pedersen, 2012). Most recently, a new identified hormone secreted by muscle tissue in mouse, irisin, has been discovered. Irisin acts on white adipose cells in culture and in vivo to stimulate UCP1 expression and a broad program of brown-fat-like development. Irisin was induced with exercise in mice and humans which caused an increase in energy expenditure in mice with no changes in movement or food intake (Boström et al., 2012). Irisin was thus, promptly hypothesized as a hormone influencing body weight, obesity and type 2 diabetes mellitus, among other conditions (Sanchis-Gomar et al., 2012). Some studies have indicated that circulating levels of irisin in humans correlate positively with anthropometric parameters such as BMI, fat mass, fat free mass, and are higher in obese patients compared to lean ones (Stengel et al., 2013; Huh et al., 2012; Roca-Rivada et al., 2013; Crujeiras et al., 2014; Pardo, 2014). Studies have shown an association between irisin levels, insulin resistance and the metabolic syndrome (Park et al., 2013; de la Iglesia et al., 2014; Crujeiras et al., 2014; Pardo et al., 2014). However, some others have found a negative correlation with anthropometric parameters, finding lower irisin levels in obese patients (Moreno-Navarrete et al., 2013). Noteworthy, all these studies have been performed in adults. To date, there are only two studies evaluating irisin levels in children. One found that a 1-year long lifestyle intervention program was associated with an elevation in irisin levels in obese children, although no correlation was found between irisin levels and anthropometric markers (Blüher et al., 2014). The other study investigated normal weight Saudi children and found correlations between circulating irisin and glucose and HDLc, but a negative association with insulin resistance (Al-Daghri et al, 2014). Besides, associations between irisin levels and adiponectin, leptin and resistin in the set of obesity have been explored, the three of them are implicated in the physiopatology of obesity. As there are still conflicting data regarding the association of irisin with anthropometric parameters, obesity and the metabolic syndrome, as well as its 'association with other adiponectines, and most important, there is scarce data of these associations in children, the objective of this study will be to correlate the circulating irisin and adipokines levels across a broad spectrum of body mass index ranging from undernourished to obese as well as with insulin resistance and risk factors for the metabolic syndrome in Hispanic children. The sample size with statistical power for this study yielded a sample of 40 children. Frozen stored plasma (-80°C) will be taken from a previous study performed in children which has been published (Elizondo-Montemayor et al., 2014). The samples will be divided into five groups, 8 per group, according to the CDC and American Academy of Pediatrics body mass index percentile classification: 1.) underweight = <3 percentile; 2.) normal weight = >3 - < 85 percentile; 3.) Overweight = >85 - < 95 percentile, and 4.) obese = > 95 percentile. The fifth group will correspond to children with known metabolic syndrome according to the classification specified by Cooks et al (2008). Anthropometric measurements will include BMI, percentile BMI, waist circumference, % body fat, fat mass, fat free mass, and triceps skin fold. Biochemical measurements will include glucose, total cholesterol, low-density cholesterol (LDL), high-density cholesterol (HDL-c) and triglycerides. Clinical measurements will include blood pressure, physical activity records and dietary habits. All biochemical, anthropometric and clinical measurements were previously performed in a former published study (Elizondo-Montemayor et al., 2014). Irisin, adiponectin and leptin will be measured in plasma media using commercial ELISA kits.
