Abstract
BACKGROUND Obesity has reached epidemic dimensions in recent decades. Bariatric surgery (BS) is one of the most effective interventions for weight loss and metabolic improvement in patients with obesity. Short-chain fatty acids (SCFA) are gut microbiota-derived metabolites with a key role in body weight control and insulin sensitivity. Although BS is known to induce significant changes in the gut microbiota composition, its impact on the circulating levels of certain metabolites produced by the gut microbiota such as SCFA remains poorly understood. OBJECTIVE To determine the impact of BS on the circulating SCFA levels in patients with severe obesity. SETTING University hospital. METHODS An observational, prospective study was performed on 51 patients undergoing Roux-en-Y gastric bypass. Plasma samples were collected at baseline (1 day before surgery) and at 6 and 12 months after BS. Plasma SCFA levels were determined by liquid chromatography-mass spectrometry. RESULTS The results revealed significant changes in the circulating levels of SCFA after BS. A marked increase in propionate, butyrate, isobutyrate, and isovalerate levels and a decrease in acetate, valerate, hexanoate, and heptanoate levels were observed 12 months after BS. Furthermore, the changes in the levels of propionate, butyrate, and isobutyrate negatively correlated with changes in body mass index, while those of isobutyrate correlated negatively with changes in the homeostatic model assessment for insulin resistance index. CONCLUSION These results suggest that propionate, butyrate, and isobutyrate levels could be related to weight loss and improved insulin sensitivity in patients with severe obesity after BS.

Abstract
Childhood obesity has reached epidemic levels in developed countries and is becoming a major cause for concern in the developing world. The causes of childhood obesity are complex and multifactorial, involving the interaction between individual genetics and environmental and developmental factors. Among the environmental factors, there is a growing interest in understanding the possible relationship between the so-called environmental obesogens and the development of obesity in children. Exposure to these obesogens such as phthalates, bisphenol A, or parabens, has been identified as a promoter of obesity through different mechanisms such as the alteration of adipocyte development from mesenchymal progenitors, the interference with hormone receptors, and induced inflammation. However, less attention has been paid to the inheritance of epigenetic modifications due to maternal exposure to these compounds during pregnancy. Thus, the aim of this review is to summarize the current knowledge of epigenetic modifications due to maternal exposure to those obesogens during pregnancy as well as their potential implication on long-term obesity development in the offspring and transgenerational inheritance of epiphenotypes.

Abstract
PURPOSE The aim of this study was to evaluate the efficiency of a joint intervention that included educational components, self-assessment, and information to optimise diabetes control through the introduction of instant capillary glycosylated haemoglobin (HbA1c) determination in Primary Care. MATERIALS AND METHODS A multicentre prospective descriptive study was carried out over 3years in 10Primary Care Centres of the Area VII Murcia East. At the end of the study there were 804 patients with type 2 diabetes (DM2). Patients were divided into 4 groups based on initial values of HbA1c, and if changes in their treatment were needed. HbA1c, body mass index, and blood pressure were monitored. A financial assessment was also performed on the impact of the implementation of a protocol to measure instant capillary RESULTS: A significant reduction was observed in HbA1c values. The initial HbA1c mean value was 7.4±1.4%, which decreased to a final value of 6.9±1.0% (P<.001). At the end of the study, 71.4% of patients included reached diabetic control objectives. In addition, the financial assessment demonstrated that the implementation of this diabetes control system led to a decrease of the 24.7% in spending on glucose strips after the first year of study in Area VII Murcia Health Service. CONCLUSIONS The introduction of capillary HbA1c determination in Primary Care has demonstrated to improve diabetes control and the efficiency of the health personnel. Furthermore, a reduction in the health costs of patients with DM2 was also shown.
