Abstract
INTRODUCTION Classic cardiovascular risk factors do not explain all the cardiovascular events. Obstructive sleep apnoea (OSA) has been proposed as a potential and prevalent cardiovascular risk factor. Our study aimed to describe the prevalence of OSA in a middle-aged cohort with mild-moderate cardiovascular risk and evaluate its association with atherosclerotic disease. METHODS This is an observational cross-sectional ancillary study of the ILERVAS project which was aimed to study subclinical arterial disease in a cohort with mild-moderate cardiovascular risk. In a sample of consecutive subjects, we performed a sleep study and evaluate OSA prevalence and its association with carotid and femoral atheroma plaques and atherosclerotic burden. RESULTS Overall, 966 subjects with a median age of 57 years (25-75th percentile; 52-62) and a body mass index (BMI) of 28.5kg/m2 (25.6-31.6) were included. Of these, 72.6% (69.7%-75.3%) had OSA (apnoea-hypopnoea index (AHI)≥5/h); 35.7% (32.8%-38.8%) had mild OSA (AHI 5-14.9/h) and 36.9% (33.9%-39.9%) had moderate/severe OSA (AHI≥15/h). Mean oxygen saturation and the percentage of time with oxygen saturation<90% (CT90) were associated with atherosclerotic burden (eβ (95%CI) 0.932 (0.892, 0.974); 1.005 (1.002, 1.009), respectively) and total plaque (OR (95%CI) 0.88 (0.797,0.971); 1.013 (1.004,1.021), respectively). No association with the AHI or oxygen desaturation index was found. CONCLUSIONS This study confirms a high prevalence of OSA in patients with mild-moderate cardiovascular risk and shows an association between atherosclerotic burden, total and femoral plaque with CT90 and mean oxygen saturation, suggesting the importance of OSA-related hypoxaemia in the induction of atherosclerotic disease.

Abstract
CONTEXT Information concerning the risk-benefit profile of bariatric surgery in subjects with liver cirrhosis is scarce. Our aim was to describe the long-term outcomes of bariatric surgery in a cohort of patients with liver cirrhosis submitted to bariatric surgery. METHODS This was a multicenter, retrospective observational study performed by the Obesity Group of the Spanish Society of Endocrinology and Nutrition (GOSEEN), with a review of patients with cirrhosis who had undergone bariatric surgery during the period from April 2004 to March 2017 in ten public reference hospitals in Spain. RESULTS Data on 41 patients with cirrhosis submitted to obesity surgery were collected (mean age 53.8 ± 7.9 years, 46.3% women, presurgical BMI 45 ± 8.3 kg/m2). All but one patient belonged to Child-Pugh class A, and sleeve gastrectomy was conducted in 68.3% of cases. Percentage of total weight loss (%TWL) was 26.33 ± 8.3% and 21.16 ± 15.32% at 1 and 5 years after surgery, respectively. This was accompanied by a significant reduction of type 2 diabetes, high blood pressure, and dyslipidemia and by an improvement of liver enzymes over time. Model for End-Stage Liver Disease (MELD) index increased from 7.2 ± 1.9 to 9.8 ± 4.6 after 5 years. Seven patients (17%) developed early postsurgical complications. No postsurgical mortality was observed. During follow-up, only five patients developed liver decompensation. CONCLUSIONS Bariatric surgery in selected patients with liver cirrhosis has metabolic benefits that could have a positive impact on liver prognosis.

Abstract
AIMS: To study the response of clinical variables (HbA1c , body weight, lipid profile and blood pressure) over 24 months of liraglutide treatment in a real-world clinical setting, and to describe the evolution of HbA1c and body weight reduction in response to liraglutide treatment by employing generalized additive mixed models (GAMMs). METHODS We included people aged ≥ 18 years with Type 2 diabetes mellitus that initiated liraglutide treatment between November 2011 and May 2015. Demographic and clinical data were retrieved retrospectively over 24 months from electronic medical records with a median duration of observation of 7.0 (IQR 3.0-12.0) months. RESULTS Individuals that initiated liraglutide therapy were obese (BMI 39.1 kg/m2 ), with inadequate HbA1c (68 mmol/mol [8.4%]), blood pressure and lipid levels. Upon liraglutide treatment, HbA1c , body weight, mean systolic and diastolic blood pressure, and lipid levels decreased gradually. GAMMs demonstrated that longer treatment with liraglutide was a predictor of improved HbA1c response, whereas higher baseline HbA1c , longer Type 2 diabetes duration and treatment with insulin were predictors of worse HbA1c response. Higher baseline weight, longer treatment with liraglutide and the interaction between metformin and time were predictors of improved weight response. CONCLUSIONS In this real-world study, we showed the effectiveness of liraglutide in improving body weight, HbA1c , mean systolic and diastolic blood pressure, and lipid levels. GAMMs indicated that baseline HbA1c and weight, time of treatment with liraglutide, diabetes duration and the use of metformin or insulin are predictors of clinical response to liraglutide.

Abstract
BACKGROUND This study aims to describe the long-term outcomes of bariatric surgery in a cohort of patients with type 1 diabetes (T1DM). METHODS Thirty-two patients with T1DM and initial BMI of 41.3 ± 4.8 kg/m2 were studied, 18.7 % undergoing duodenal switch (DS), 34.4 % gastric bypass, and 46.9 % sleeve gastrectomy and followed-up after surgery for 4.6 ± 2.6 years. Changes in BMI, HbA1c, insulin requirements, evolution of comorbidities, and microvascular complications were registered annually after surgery. RESULTS Percentage of total weight loss (%TWL) 12 months after surgery was 30.4 ± 9.2 % and at 5 years, it decreased to 28.1 ± 11.5 % (p = 0.02). HbA1c was reduced during the first year from 8.5 ± 1.3 to 7.9 ± 1.4 %, p = 0.016. In the long-term, HbA1c returned to baseline values. There was a sustained reduction of 51 % in total daily insulin dose, and the decrease in the number of patients with hypertension, dyslipidemia, and obstructive sleep apnea was 42.8, 25, and 66 %, respectively. Retinopathy remained mainly unaffected, and 25 % of patients with microalbuminuria regressed to normoalbuminuria. CONCLUSIONS Bariatric surgery in patients with T1DM mainly provides benefits of weight reduction, on insulin requirements, obesity comorbidities, and some benefits in diabetes complications, but might have only minimal effect on the glycemic control in the long term. This trial was registered at www.controlledtrials.com as ISRCTN49980913.

Abstract
BACKGROUND AND OBJECTIVE Advanced glycation end-products (AGEs) are a marker of metabolic memory. Their levels increases when oxidative stress, inflammation, or chronic hyperglycemia exists. The role of morbid obesity in AGE levels, and the impact of bariatric surgery on them are unknown. PATIENTS AND METHOD An observational study with three sex- and age-matched cohorts: 52 patients with obesity, 46 patients undergoing bariatric surgery in the last 5 years, and 46 control subjects. AGE were measured using skin autofluorescence (SAF) in the forearm with an AGE Reader™ (DiagnOptics Technologies, Groningen, The Netherlands). Presence of metabolic syndrome was assessed. RESULTS Patients with morbid obesity had higher SAF levels (2.14±0.65AU) than non-obese subjects (1.81±0.22AU; P<.001), which was mainly attributed to obese subjects with metabolic syndrome (2.44±0.67 vs. 1.86±0.51AU; P<.001). After bariatric surgery, SAF continued to be high (2.18±0.40AU), and greater as compared to the non-obese population (P<.001). A multivariate analysis showed that age and presence of metabolic syndrome (but not sex or body mass index) were independently associated to SAF (R2=0.320). CONCLUSION SAF is increased in patients with morbid obesity and metabolic syndrome, mainly because of the existence of type 2 diabetes mellitus. In the first 5 years following bariatric surgery, weight loss and metabolic improvement are not associated with a parallel decrease in subcutaneous AGE levels.
